# PREFACE

The NIOSH Pocket Guide to Chemical Hazards presents information taken from the NIOSH/OSHA Occupational Health Gu idelines for Chemical Hazards , from National Institute for Occupational Safety and Hea lth (NIOSH) criteria documents and Current Intelligence Bulletins, and from recognized references in the fields of industrial hygiene, occupational medicine, toxicology, and analytical chemistry. The information is presented in tabular form to provide a quick, convenie nt source of information on general industrial hygiene practices. The information in the Pocket Guide includes chemical structures or formulas, identification codes, synonyms, exposure limits, chem ical and physical properties, incompatibilities and reactivities, measurement methods, respirator selections, signs and symptoms of exposure, and procedures for emergency treatment.

The information assembled in the original 1978 printing of the Pocket Guide was the result of the Standards Completion Program, a join t effort by NIOSH and the Department of Labor to develop supplemental requireme nts for the approximately 380 workplace environmental exposure standards adopted by the Occupational Safety and Health Administration (OSHA) in 1971.

Listed below are changes that were made for this edition (2005-149) of the Pocket Guide :

• New layout for the Chemical Listing section.

• Recommendations for particulate respirator s have been revised to incorporate “Part 84” terminology. See “Recommendati ons for Respirator Selection” on page xiv for a more thorough explan ation of these changes.

• The Synonym and Trade Name Index has been expanded. This index is now called the Chemical, Synonym, a nd Trade Name Index (page 383).

• Some ID and Guide Numbers were changed to reflect changes made in the 2004 Emergency Response Guidebook (http://hazmat.dot.gov/pubs /erg/gydebook.htm).

• Appendix E (page 351) has been revised. It now contains OSHA respirator requirements for 28 chemicals or hazardous substances that were identified in the preamble to the OSHA Respiratory Protection Standard (29 CFR 1910.134).

• Other minor technical cha nges have also been made since the February 2004 edition. (For the most current information and updates, consult the electronic version on the NIOSH Web site: http ://www.cdc.gov/nios h/npg/npg.html.)

Listed below are changes made for the 3 rd 

## printing of this edition of the Pocket Guide :

• Changes were made to re flect the new OSHA PEL for hexavalent chromium.

• The NIOSH REL for coal mine dust was added to the coal dust entry.

• A few other minor technical changes have been made.

# INTRODUCTION

The NIOSH Pocket Guide to Chemical Hazards provides a concise source of general industrial hygiene information for worker s, employers, and occupational health professionals. The Pocket Guide presents key information and data in abbreviated tabular form for 677 chemicals or substance groupi ngs commonly found in the work environment (e.g., manganese compounds, tellurium com pounds, inorganic tin compounds, etc.). The industrial hygiene information found in the Pocket Guide assists users to recognize and control occupational chemical hazards. The chemicals or substances contained in this revision include all substances for which the National Institute for Occupational Safety and Health (NIOSH) has recommended exposure li mits (RELs) and thos e with permissible exposure limits (PELs) as found in the Occupational Safety and Health Administration (OSHA) Occupational Safety and H ealth Standards (29 CFR 1910.1000 – 1052).

Background

In 1974, NIOSH (which is responsible for recommending health and safety standards) joined OSHA (whose jurisdictions include pr omulgation and enforcement activities) in developing a series of occupational health st andards for substances with existing PELs. This joint effort was labeled the Standards Completion Program and involved the cooperative efforts of severa l contractors and personnel fro m various divisions within NIOSH and OSHA. The Standards Completion Program developed 380 substance-specific draft standards with supporting documentation that contained techni cal information and recommendations needed for the promulgation of new occupational health regulations. The Pocket Guide was developed to make the technical information in those draft standards more conveniently available to workers, employ ers, and occupational health professionals. The Pocket Guide is updated periodi cally to reflect new data regarding the toxicity of various substances and any changes in expos ure standards or recommendations. (For the most current information and updates, cons ult the electronic version on the NIOSH Web site: http://www.cdc.gov/niosh/npg/npg.html.)

Data Collection and Application

The data collected for this revision were derived from a variety of sources, including NIOSH policy documents such as Criteria Documents and Current Intelligence Bulletins (CIBs), and recognized references in the fields of industrial hygiene, occupational medicine, toxicology, and analytical chemistry.



# NIOSH RECOMMENDATIONS

Acting under the authority of the Occupationa l Safety and Health Act of 1970 (29 USC Chapter 15) and the Federal Mine Safety and Health Act of 1977 (30 USC Chapter 22), NIOSH develops and periodi cally revises recommended exposure limits (RELs) for hazardous substances or conditio ns in the workplace. NIOSH also recommends appropriate preventive measures to reduce or eliminate the adverse health and safety effects of these

## viii hazards. To formulate these recommendations, NIOSH evaluates all known and available medical, biological, engineering, chemical, trad e, and other information relevant to the hazard. These recommendations are then published and transmitted to OSHA and the Mine Safety and Health Administ ration (MSHA) for use in promulgating legal standards.

NIOSH recommendations are published in a va riety of documents. Criteria documents recommend workplace exposure limits and approp riate preventive meas ures to reduce or eliminate adverse health effects and accidental injuries.

Current Intelligence Bulletins (CIBs) are issued to disseminate new scientific information about occupational hazards. A CIB may draw attention to a formerly unrecognized hazard, report new data on a known hazard, or present information on hazard control.

Alerts, Special Hazard Reviews, Occupational Hazard Assessments, and Technical Guidelines support and complement the othe r standard development activities of the Institute. Their purpose is to assess the safety and health problems associated with a given agent or hazard (e.g., the potential for injury or for carcinogenic, mutagenic, or teratogenic effects) and to recommend appropriate contro l and surveillance methods. Although these documents are not intended to supplant the mo re comprehensive criteria documents, they are prepared in order to assist OSHA a nd MSHA in the formulation of regulations.

In addition to these publicati ons, NIOSH periodically presents testimony before various Congressional committees and at OSHA and MSHA rulemaking hearings.

Recommendations made through 1992 are ava ilable in a single compendium entitled NIOSH Recommendations for Occupational Saf ety and Health: Compendium of Policy Documents and Statements [DHHS (NIOSH) Publication No. 92-100] (http://www.cdc.gov/niosh/92-100.html). More recent recommendations are available on the NIOSH Web site (http://www.cd c.gov/niosh). Copies of the Compendium may be ordered from the NIOSH Publications office (800-356-4674).



# HOW TO USE THIS POCKET GUIDE

The Pocket Guide has been designed to provide ch emical-specific data to supplement general industrial hygiene knowledge . Individual tables for each chemical pres ent this data in the Chemical Listing section (page 1). To maximize the amount of data provided in the limited space in these tables, abbreviations and codes have been used extensively. These abbreviations and codes, which have been desi gned to permit rapid comprehension by the regular user, are discussed for each field in these chemical tables in the following subsections.

Chemical Name

The chemical name found in the OSHA Genera l Industry Air Contaminants Standard (29 CFR 1910.1000) is listed in the blue box in the to p left portion of each chemical table. This name is referred to as the “primary name” in the Chemical, Synonym, and Trade Name Index (page 383).

## ix Structure/Formula

The chemical structure or formula is listed in the field to the right of the chemical name in each chemical table. Carbon-carbon double bonds (-C=C-) and carbon-carbon triple bonds (-C ≡ C-) have been indicated where applicable.

CAS Number

This section lists the Chemical Abstracts Service (CAS) registry number. The CAS number, in the format xxx-xx-x, is unique for each ch emical and allows efficient searching on computerized data bases. A page index fo r all CAS registry numbers listed is included at the back of the Pocket Guide (page 374) to help the user locate a specific substance.

RTECS Number

This section lists the NIOSH Registry of T oxic Effects of Chemi cal Substances (RTECS ® 

## ) number, in the format ABxxxxxxx. RTECS ® 

## may be useful for obtaining additional toxicologic information on a specific substance.

RTECS ® 

## is a compendium of data extracted from the open scientific literature. On December 18, 2001, CDC’s Technology Transfer Office, on behalf of NIOSH, successfully completed negotiating a “PHS Trademark Licensing Agreement” for RTECS ® 

## . This nonexclusive licensing agreement provides for the transfer and continued development of the “RTECS ® 

## database and its trademark” to MDL Info rmation Systems, Inc. (MDL), a wholly owned subsidiary of Elsevier Science, Inc. Under this agreement, MD L will be responsible for updating, licensing, marketing, and distributing RTECS ® 

## . For more information visit the MDL Web site (http://www.mdli.com).

The RTECS ® 

## entries for chemicals listed in the Pocket Guide can be viewed on the NIOSH Web site (http://www.cdc.gov/niosh/npg/npg.html ) or on the CD-ROM version of the Pocket Guide (see page iii for or dering information).

IDLH

This section lists the immediat ely dangerous to life or health concentrations (IDLHs). For the June 1994 Edition of the Pocket Guide , NIOSH reviewed and in many cases revised the IDLH values. The criteria utilized to determin e the adequacy of the original IDLH values were a combination of those used during th e Standards Completion Program and a newer methodology developed by NIOSH. These “int erim” criteria formed a tiered approach, preferentially using acute human toxicity data, followed by acute animal inhalation toxicity data, and then by acute animal oral toxicity data to determine a preliminary updated IDLH value. When relevant acute toxicity data were insufficient or unavailable, NIOSH also considered using chronic toxicity data or an analogy to a chemically similar substance. NIOSH then compared these preliminary values with the following criteria to determine the updated IDLH value: 10% of lower explosiv e limit (LEL); acute animal respiratory irritation data (RD 50 

## ); other short-term exposure guidelines; and the NIOSH Respirator Selection Logic (DHHS [NIOSH] Publication No. 2005-100;

## x http://www.cdc.gov/niosh/docs/2005-100). The Documentation for Immediately Dangerous to Life or Health Concentrations (NTIS Publication Number PB-94-195047) further describes these criteria and provides in formation sources for both the original and revised IDLH values (http: //www.cdc.gov/niosh/idlh/idlh- 1 

## .html). NIOSH currently is assessing the various uses of IDLHs, whether th e criteria used to derive the IDLH values are valid, and if other information or criteria should be utilized.

The purpose for establishing an IDLH value in the Standards Completion Program was to determine the airborne concentration from whic h a worker could escape without injury or irreversible health effects from an IDLH exposur e in the event of the failure of respiratory protection equipment. The IDLH was consid ered a maximum concentration above which only a highly reliable breathi ng apparatus providing maximum worker protection should be permitted. In determining IDLH values, NI OSH considered the ability of a worker to escape without loss of life or irreversible health effects along with certain transient effects, such as severe eye or respiratory irritation, disorientation, and incoordination, which could prevent escape. As a safety margin, IDLH values are based on effects that might occur as a consequence of a 30-minute exposure. Howe ver, the 30-minute period was NOT meant to imply that workers should stay in the work environment any longer than necessary; in fact, EVERY EFFORT SHOULD BE MADE TO EXIT IMMEDIATELY!

The NIOSH Respirator Selection Logic defines IDLH exposure conditions as “conditions that pose an immediate threat to life or health, or conditions that pose an immediate threat of severe exposure to contaminan ts, such as radioactive materi als, which are likely to have adverse cumulative or delayed effects on hea lth.” The purpose of establishing an IDLH exposure concentration is to ensure that the worker can escape from a given contaminated environment in the event of failure of th e respiratory protection equipment. The Respirator Selection Logic uses IDLH values as one of several respirator selection criteria. Under the Respirator Selection Logic , the most protective respirators (e.g., a self-contained breathing apparatus equipped with a full facepiece a nd operated in a pressure-demand or other positive-pressure mode) would be selected for firefighting, exposure to carcinogens, entry into oxygen-deficient atmospheres, in em ergency situations, during entry into an atmosphere that contains a s ubstance at a concentration greater than 2,000 times the NIOSH REL or OSHA PEL, and for entry into IDLH at mospheres. IDLH valu es are listed in the Pocket Guide for over 380 substances.

The notation “ Ca ” appears in the IDLH field for all substances that NIOSH considers potential occupational ca rcinogens. However, IDLH values that were originally determined in the Standards Completion Program or were subsequently revised are shown in brackets following the “ Ca ” designations. “ 10%LEL ” indicates that the IDLH was based on 10% of the lower explosive limit for safety consid erations even though the relevant toxicological data indicated that irreversible health effects or impairment of escape existed only at higher concentrations. “ N.D. ” indicates that an IDLH value has not been determined for that substance. Appendix F (page 361 ) contains an explanation of the “Effective” IDLHs used for four chloronaphthalene compounds.

## xi Conversion Factors

This section lists factors for the conversion of ppm (parts of vapor or gas per million parts of contaminated air by volume) to mg/m 3 

## (milligrams of vapor or gas per cubic meter of contaminated air) at 25°C and 1 atmosphere for chemicals with exposure limits expressed in

ppm.

DOT ID and Guide Number

This section lists the U.S. Department of Transportation (DOT) Identification numbers and the corresponding Guide numbers. Their form at is xxxx yyy. The Identification (ID) number (xxxx) indicates that the chemical is regulated by DOT. The Guide number (yyy) refers to actions to be taken to stabilize an emergency situation; this information can be found in the 2004 Emergency Response Guidebook (Office of Hazar dous Materials Initiatives and Training [DHM-50], Research and Special Programs Administration, U.S. Department of Transportation, 400 7 th 

## Street, S.W., Washington, D.C. 20590-0001; for sale by the U.S. Government Printing Office, S uperintendent of Documents, P.O. Box 371954, Pittsburgh, PA 15250-7954). This information is also available on the CD-ROM and Web site versions of the Pocket Guide (http://www.cdc.gov/niosh/npg/npg.html). A page index for all DOT ID numbers listed is provided on page 379 to help the user locate a specific substance; please note however, that many DOT numbers are not unique for a specific substance.

Synonyms and Trade Names

This section contains an alphabetical list of common synonyms and trade names for each chemical. A page index for all chemical names, synonyms, and trade names listed in the Pocket Guide is included on page 383.

Exposure Limits

The NIOSH recommended exposure limits ( REL s) are listed first in this section. For NIOSH RELs, “ TWA ” indicates a time- weighted average concentration for up to a 10-hour workday during a 40-hour workweek. A short-term exposure limit (STEL) is designated by

“ ST ” preceding the value; unless noted otherwise, the STEL is a 15-minute TWA exposure that should not be exce eded at any time during a workday. A ceiling REL is designated by

“ C ” preceding the value; unless noted otherwise, the ceiling value should not be exceeded at any time. Any substance that NIOSH considers to be a potential occupational carcinogen is designated by the notation “ Ca ” (see Appendix A [page 342], which contains a brief discussion of potential occupational carcinogens).

The OSHA permissible exposure limits ( PEL s), as found in Tables Z-1, Z-2, and Z-3 of the OSHA General Industry Air Contaminants Standard (29 CFR 1910.1000), that were effective on July 1, 1993* and which are currently enforced by OSHA are listed next.

*In July 1992, the 11th Circuit Court of Appeals in its decision in AFL-CIO v. OSHA, 965 F.2d 962 (11th Cir., 1992) vacated more protective PELs set by OSHA in 1989 for 212 substa nces, moving them back to PELs

## xii established in 1971. The appeals court also vacated new PELs for 164 substances that were not previously regulated. Enforcement of the court decision began on June 30, 1993. Although OSHA is currently enforcing exposure limits in Tables Z-1, Z- 2, and Z-3 of 29 CFR 1910.1000 which were in effect before 1989, violations of the “general duty clause” as contained in Section 5(a) (1) of th e Occupational Safety and Health Act may be considered when worker e xposures exceed the 1989 PELs for the 164 substances that were not previous ly regulated. The substances for which OSHA PELs were va cated on June 30, 1993 are indicated by the symbol “ † ” following OSHA in this section and previous values (the PELs that were vacated) are listed in Appendix G (page 362).

TWA concentrations for OSHA PEL s must not be exceeded during any 8-hour workshift of a 40-hour workweek. A STEL is designated by “ ST ” preceding the value and is measured over a 15-minute period unless noted otherwise. OSHA ceiling concentrations (designated by “ C ” preceding the value) must not be exceed ed during any part of the workday; if instantaneous monitoring is not feasible , the ceiling must be assessed as a 15-minute TWA exposure. In addition, there are a number of substances from Table Z-2 (e.g., beryllium, ethylene dibromide) that have PEL ceiling values that must not be exceeded except for specified excursions. For example, a “5-minute maximum peak in any 2 hours” means that a 5-minute exposure above the ceiling value, but never above the maximum peak, is allowed in any 2 hours during an 8-hour workday. Appendix B (page 344) contains a brief discussion of substa nces regulated as car cinogens by OSHA.

Concentrations are given in ppm, mg/m 3 

## , mppcf (millions of particles per cubic foot of air as determined from counting an impinger sample), or fibers/cm 3 

## (fibers per cubic centimeter). The “ [skin] ” designation indicates the potential for dermal absorption; skin exposure should be prevented as necessary thr ough the use of good work practices, gloves, coveralls, goggles, and other appr opriate equipment. The “ (total) ” designation indicates that the REL or PEL listed is for "total particulate" versus the “ (resp) ” designation which refers to the “respirable fraction” of the airborne particulate.

Appendix C (page 345) contains more detailed discussions of the sp ecific exposure limits for certain low-molecular-weight aldehydes, asbe stos, various dyes (benzidine-, o-tolidine-, and o-dianisidine-based), carbon black, ch loroethanes, the various chromium compounds (chromic acid and chromates, chromium (II) and chromium(III) compounds, and chromium metal), coal tar pitch volatiles, coke oven emissions, cotton dust, lead, mineral dusts, NIAX® Catalyst ESN, trichlor oethylene, and tungsten carb ide (cemented). Appendix D (page 350) contains a brief discussi on of substances included in the Pocket Guide with no established RELs at this time. Appendi x F (page 361) contains miscellaneous notes regarding the OSHA PEL for benzene, and A ppendix G (page 362) lis ts the OSHA PELS that were vacated on June 30, 1993.

Measurement Methods

The section provides a source (NIOSH or OSHA) and the corresponding method number for measurement methods which can be used to determine the exposure for the chemical or

## xiii substance. Unless otherwise noted, the NI OSH methods are from the 4th edition of the NIOSH Manual of Analytical Methods (DHHS [NIOSH] Publication No. 94-113 [http://www.cdc.gov/niosh/nmam]) and supplements. If a different edition of the NIOSH Manual of Analytical Methods is cited, the appropriate edition and, where applicable, the volume number are noted [e.g., II-4 (2nd edition, volume 4)]. The OSHA methods are from the OSHA Web site (http://w ww.osha-slc.gov/dts/s ltc/methods). “None available” means that no method is availabl e from NIOSH or OSHA. Table 1 (page xvii) lists the editions, volumes, and supplements of the NIOSH Manual of Analytical Methods

.

Each method listed is the recommended met hod for the analysis of the compound of interest. However, the method may not have been fully optimized to meet the specific sampling situation. Note that some methods are only partia lly evaluated and have been used in very limited sampling situations. Revi ew the details of the method and consult with the laboratory performing the analysis regard ing the applicability of the method and the need for further modifications to the method in order to adjust for the particular conditions.

Physical Description

A brief description of the appearance and odor of each substance is provided in the physical description section. Notations are made as to whether a substance can be shipped as a liquefied compressed gas or whether it has major use as a pesticide.

WASH SKIN...... Recommends when workers should wash the spilled chemical from the body in addition to normal washing (e.g., before eating).

REMOVE.............. Advises workers when to remove clothing that has accidentally become wet or significantly contaminated.

CHANGE............. Recommends whether routin e changing of clothing is needed. PROVIDE............ Recommends the need for ey ewash fountains and/or quick drench facilities.

Recommendations for Respirator Selection

This section provides a condensed table of allowable respirators to be used for those substances for which IDLH values have been determined, or for which NIOSH has previously provided respirator recommendations (e.g., in criteria documents or Current Intelligence Bulletins) for ce rtain chemicals. Th ere are, however, 186 ch emicals listed in

## xv the Pocket Guide for which IDLH values have yet to be determined. Since the IDLH is a critical component for completing the Respirat or Selection Logic for a given chemical, the Pocket Guide does not provide respiratory reco mmendations for t hose 186 chemicals without IDLH values. As new or revised ID LH values are developed for those and other chemicals, NIOSH will provide appropriate respirator recommendations. (Updated information on the Pocket Guide can be found on the NIOSH Web site (http://www.cdc.gov/niosh/npg/npg.ht ml) and incorporated into subsequent editions of the Pocket Guide. [Appendix F (page 361) contains an e xplanation of the “Effective” IDLHs used for four chloronaphthalene compounds.]

In 1995, NIOSH developed a new se t of regulations in 42 CFR 84 (also referred to as “Part 84”) for testing and certifying non-powered, air-pu rifying, particulate-filter respirators. The new Part 84 respirators have passed a more demanding certification test than the old respirators (e.g., dust; dust and mist; dust, mi st, and fume; spray paint; pesticide) certifiedunder 30 CFR 11 (also referred to as “Part 11”). Recommendations for non-powered, airpurifying particulate respirators have been updated from previous editions of the Pocket Guide to incorporate Part 84 respirators; Part 11 terminology has been removed. See Table 4 (page xxv) for information concerning the selection of N-, R-, or P-series (Part 84) particulate respirators.

In January 1998, OSHA revised its respiratory protection standard (29 CFR 1910.134). Among the provisions in the revised standard is the requirement for an end-of-service-life indicator (ESLI) or a change schedule when air-purifying respirators with chemical cartridges or canisters are used for protection against gases and vapors [29 CFR 1910.134(d)(3)(iii)]. (Note: All respirator codes containing “ Ccr ” or “ Ov ” are covered by this requirement.) In the Pocket Guide , air-purifying respirators (without ESLIs) for protection against gases and va pors are recommended only for chemicals with adequate warning properties, but now these respirators may be selected regardless of the warning properties. Respir ator recommendations in the Pocket Guide have not been revised in this edition to reflect the OSHA requirements for ESLIs or change schedules.

Appendix A (page 342) lists the NIOSH carcinog en policy. Respirator recommendations for carcinogens in the Pocket Guide have not been revised to reflect this policy; these recommendations will be revised in future editions.

The first line in the entry indicates whether the “NIOSH” or the “OSHA” exposure limit is used on which to base the respirator recomme ndations. The more protective limit between the NIOSH REL or the OSHA PEL is always used. “NIOSH/OSHA” indicates that the limits are equivalent.

Each subsequent line lists a maximum use con centration (MUC) followed by the classes of respirators that are acceptable for use up to the MUC. Codes for the various categories of respirators, and Assigned Protect ion Factors (APFs) for these respirators, are listed in Table 3 (page xx). Individual respirator cla sses are separated by diagonal lines ( / ). More protective respirators may be worn. The symbol “ § ” is followed by the classes of respirators that are acceptable for emergenc y or planned entry into unknown concentrations or entry into IDLH conditions. “ Escape ” indicates that the respirators are to be used only

## xvi for escape purposes. For each MUC or condition, this entry lists only those respirators with the required APF and other use restrictions based on the NIOSH Respirator Selection Logic

.

All respirators selected must be approved by NIOSH under the provisions of 42 CFR 84. The current listing of NIOSH/MSHA certif ied respirators can be found in the NIOSH Certified Equipment List , which is available on the NIOSH Web site (http://www.cdc.gov/niosh/npptl/topi cs/respirators/cel).

A complete respiratory protection program must be implemented and must fulfill all requirements of 29 CFR 1910.134. A respiratory protection program must include a written standard operating procedure covering regular training, fit-testing, fit-checking, periodic environmental monitoring, main tenance, medical monitoring, inspection, cleaning, storage and periodic program evaluation. Selection of a specific respir ator within a given class of recommended respirators depends on the particular situation; this choice should be made only by a knowledgeable person. REMEMBER: Air-purifying respirators will not protect users against oxygen-deficient atmospheres, and they are not to be used in IDLH conditions. The only respirators recommended fo r fire fighting are self-contained breathing apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure mode. Additional information on the selection and use of respirators can be found in the NIOSH Respirator Selection Logic (DHHS [NIOSH] Publication No. 2005-100) and the NIOSH Guide to Industrial Respiratory Protection (DHHS [NIOSH] Publication No. 87-116), which are available on the Respirator Topic Page on the NIOSH Web site (http://www.cdc.gov/nios h/npptl/topics/respirators).

Incompatibilities and Reactivities

This section lists important ha zardous incompatibilities or react ivities for each substance.

Exposure Routes, Symptoms, and Target Organs

The first row for each substance in this sec tion lists the toxicologically important entry routes ( ER ) and whether contact with the skin or ey es is potentially ha zardous. The second row lists the potential symptoms of exposure ( SY ) and whether NIOSH considers the substance a potential occupational carcinogen ( [carc] ). The third row lists target organs ( TO ) affected by exposure to the substance (for carcinogens, the types of cancer are listed in brackets). Information in this section reflects human data unl ess otherwise noted. Abbreviations are defined in Table 5 (page xxvi).

First Aid

This section lists emergency procedures for ey e and skin contact, inhalation, and ingestion of the toxic substance. Abbreviations are defined in Table 6 (page xxviii).

# Table 4 Selection of N-, R-, or P-Se ries Particulate Respirators

1. The selection of N-, R-, and P-series filters depends on the presence of oil particles as follows:

● If no oil particles are present in the work environment, use a filter of any series (i.e., N-, R-, or P-series).

● If oil particles (e.g., lubricants, cutting fl uids, glycerine) are present, use an R- or P-series filter. Note: N-series filters cannot be used if oil particles are present.

● If oil particles are present and the filter is to be used for more than one work shift, use only a P-series filter.



## Note: To help you remember the filter series, use the following guide:

N for N ot resistant to oil, R

for R esistant to oil, P for oil P roof.

2. Selection of filter efficiency (i.e., 95%, 99%, or 99.97%) depends on how much filter leakage can be accep ted. Higher filter efficiency means lower filter leakage.

3. The choice of facepiece depends on the level of protection needed – that is, the assigned protection factor (APF) needed. See Table 3 (page xx) for APFs of respirator classes, and

see Recommendations for Respirator Selection (page xiv) for more information.

# Appendix A NIOSH POTENTIAL OCCUPATIONAL CARCINOGENS

New Policy (Adopted September 1995)

For the past 20 plus years, NIOSH has subscribed to a carcinogen policy that was published in 1976 by Edward J. Fairchild, II, Associate Dir ector for Cincinnati Operations, which called for “no detectable exposure levels for proven carci nogenic substances” (Annals of the New York Academy of Sciences, 271:200-207, 1976). This was in response to a generic OSHA rulemaking on carcinogens. Because of advances in science and in approaches to risk assessment and risk management, NIOSH has adopted a more inclusive policy. NIOSH recommended exposure limits (RELs) will be based on risk evaluations usi ng human or animal health effects data, and on an assessment of what levels can be feasibly achieved by engineering controls and measured by analytical techniques. To the extent feasible , NIOSH will project not only a no effect exposure, but also exposure levels at which there may be residual risks. This policy applies to all workplace hazards, including carcinogens, and is responsive to Section 20(a)(3) of the Occupational Safety and Health Act of 1970, which charges NIOSH to “. . .describe exposure levels that are safe for various periods of em ployment, including but not limited to the exposure levels at which no employee will suffer impaire d health or functional capacities or diminished life expectancy as a result of his work experience.”

The effect of this new policy will be the de velopment, whenever possible, of quantitative RELs that are based on human and/or animal data, as well as on the consideration of technological feasibility for controlling workplace e xposures to the REL. Under the old policy, RELs for most carcinogens were non-quantitative va lues labeled “lowest feasible concentration (LFC).” [Note: There are a few exceptions to LFC RELs for carcinogens (e.g., RELs for asbestos, formaldehyde, benzene, and ethylene oxide are quantitative values based primarily on analytical limits of detection or technological f easibility). Also, in 1989, NIOSH adopted several quantitative RELs for carcinogens from OSHA's permissible exposure limit (PEL) update.]

Under the new policy, NIOSH will also reco mmend the complete range of respirators (as determined by the NIOSH Respirator Decision Lo gic) for carcinogens with quantitative RELs. In this way, respirators will be consistently r ecommended regardless of whether a substance is a carcinogen or a non-carcinogen.

# Appendix A (Continued) NIOSH POTENTIAL OCCUPATIONAL CARCINOGENS

Old Policy

In the past, NIOSH identified numerous substa nces that should be treated as potential occupational carcinogens even though OSHA might not have identified them as such. In determining their carcinogenicity, NIOSH used the OSHA classification outlined in 29 CFR 1990.103, which states in part:

Potential occupational carcinogen means any substance, or combination or mixture of substances, which causes an increased incidence of benign and/or malignant neoplasms, or a substantial decrease in the latency period between exposure and onset of neoplasms in humans or in one or more experimental mammalian species as the result of any or al, respiratory or dermal exposure, or any other exposure which results in the induction of tumors at a site other than the site of administration. This definition also includes any substance which is metabolized into one or more potential occupational carcinogens by mammals.

When thresholds for carcinogens that would protect 100% of the population had not been identified, NIOSH usually recommended that occupational exposures to carcinogens be limited to the lowest feasible concentration. To ensure maximum protection from carcinogens through the use of respiratory protection, NIOSH also recommended that only the most reliable and protective respirators be used. These respirator s include (1) a self-contained breathing apparatus (SCBA) that has a full facepiece and is operated in a positive pressure mode, or (2) a supplied air respirator that has a full facepiece and is operated in a pressure demand or other positive pressure mode in combination with an auxiliary SCBA operated in a pressure demand or other positive pressure mode.



## Recommendations to be Revised

The RELs and respirator recommendations for carcinogens listed in this edition of the Pocket Guide still reflect the old policy. Changes in the RELs and respirator recommendations that reflect the new policy will be included in future editions.

# Appendix B THIRTEEN OSHA-REGULATED CARCINOGENS

Without establishing PELs, OSHA promulgated standards in 1974 to regulate the industrial use of the following 13 chemicals identified as potential occupational carcinogens:

• 2-Acetylaminofluorene

• 4-Aminodiphenyl

• Benzidine

• bis-Chloromethyl ether

• 3,3'-Dichlorobenzidine

• 4-Dimethylaminoazobenzene

• Ethyleneimine

• Methyl chloromethyl ether

• α -Naphthylamine

• β -Naphthylamine

• 4-Nitrobiphenyl

• N-Nitrosodimethylamine

• β -Propiolactone

Exposures of workers to these 13 chemicals ar e to be controlled through the required use of engineering controls, work practices, and persona l protective equipment, including respirators. OSHA respirator requirements for these chemical s are provided in Appendix E (page 351). See 29 CFR 1910.1003 - 1910.1016 for more specific details of these requirements.

# Appendix C SUPPLEMENTARY EXPOSURE LIMITS

Aldehydes (Low-Molecular-Weight)

Exposure to acetaldehyde has produced nasal tumors in rats and laryngeal tumors in hamsters, and exposure to malonaldehyde has prod uced thyroid gland and pancreatic islet cell tumors in rats. NIOSH therefore recommends that acetaldehyde and malonaldehyde be considered potential occupational carcinogens in conformance with the OSHA carcinogen policy. Testing has not been completed to determine the carcinogenicity of the following nine related low-molecular-weight aldehydes:

● 

## Acrolein (CAS# 107-02-8) ● 

## Paraformaldehyde (CAS# 30525-89-4)

● 

## Butyraldehyde (CAS# 123-72-8) ● 

## Propiolaldehyde (CAS# 624-67-9)

● 

## Crotonaldehyde (CAS# 4170-30-3) ● 

## Propionaldehyde (CAS# 123-38-6)

● 

## Glutaraldehyde (CAS# 111-30-8) ● 

## n-Valeraldehyde (CAS# 110-62-3)

● 

## Glyoxal (CAS# 107-22-2)

However, the limited studies to date indicate that these substances have chemical reactivity and mutagenicity similar to acetaldehyde and malona ldehyde. Therefore, NIOSH recommends that careful consideration should be given to reduci ng exposures to these nine related aldehydes. Further information can be found in NIOSH Current Intelligence Bulletin 55: Carcinogenicity of Acetaldehyde and Malonaldehyde, and Mutageni city of Related Low-Molecular-Weight Aldehydes [DHHS (NIOSH) Publication No. 91-112]. This document is available on the NIOSH Web site (http://www.cdc.gov/niosh/91112_55.html).



## Asbestos

NIOSH considers asbestos to be a potentia l occupational carcinogen and recommends that exposures be reduced to the lowest feasible concen tration. For asbestos fibers >5 micrometers in length, NIOSH recommends a REL of 100,000 fibe rs per cubic meter of air (100,000 fibers/m 3 

## ), which is equal to 0.1 fiber per cubic centimeter of air (0.1 fiber/cm 3 

## ), as determined by a 400-liter air sample collected over 100 minutes in acco rdance with NIOSH Analytical Method #7400. Airborne asbestos fibers are defined as those pa rticles having (1) an aspect ratio of 3 to 1 or greater and (2) the mineralogic characteristics (t hat is, the crystal structure and elemental composition) of the asbestos minerals and their nonasbestiform analogs. The asbestos minerals are defined as chrysotile, crocidolite, amos ite (cummingtonite-grunerite), anthophyllite, tremolite, and actinolite. In addition, airborne cleavage fragments from the nonasbestiform habits of the serpentine minerals antigorite and li zardite, and the amphibole minerals contained in the series cummingtonite-grunerite, tremolite-f erroactinolite, and glaucophane-riebeckite should also be counted as fibers provided they meet th e criteria for a fiber when viewed microscopically.

As found in 29 CFR 1910.1001, the OSHA PEL for asbestos fibers (i.e., actinolite asbestos, amosite, anthophyllite asbestos, chrysotile, crocidolite, and tremolite asbestos) is an 8-hour TWA airborne concentration of 0.1 fiber (longer than 5 micrometers and having a length to diameter ratio of at least 3 to 1) per cubic centimeter of air (0.1 fiber/cm 3 

## ), as determined by the membrane filter method at approximately 400X magnification w ith phase contrast illumination. No worker should be exposed in excess of 1 fiber/cm 3 

## (excursion limit) as averaged over a sampling period of 30 minutes.

Asphalt Fumes

The recommendations provided below are from Health Effects of Occupational Exposure to Asphalt [DHHS (NIOSH) Publication No. 2001- 110] (http://www.cdc.gov/niosh/01-110pd.html).

Occupational exposure to asphalt fumes shall be controlled so that employees are not exposed to the airborne particulates at a concentration greater than 5 mg/m 3 

## , determined during any 15-minute period.

Data regarding the potential carcinogenicity of paving asphalt fumes in humans are limited, and no animal studies have examined the carcinogen ic potential of either field- or laboratorygenerated samples of paving asphalt fume condensates. NIOSH concludes that the collective data currently available from studies on paving asphalt provide insufficient evidence for an association between lung cancer and exposure to asphalt during paving.

The results from epidemiologic studies indicate th at roofers are at an increased risk of lung cancer, but it is uncertain whether this increase can be attributed to asphalt and/or to other exposures such as coal tar or asbestos. Data from experimental studies in animals and cultured mammalian cells indicate that laboratory-genera ted roofing asphalt fume condensates are genotoxic and cause skin tumors in mice when applied dermally. Furthermore, a known carcinogen (Benzo(a)pyrene) was detected in fi eld-generated roofing fumes. The collective health and exposure data provide sufficient eviden ce for NIOSH to conclude that roofing asphalt fumes are a potential occupational carcinogen.

The available data indicate that although not all asphalt-based paint formulations may exert genotoxicity, some are genotoxic and carcinogenic in animals. No published data examine the carcinogenic potential of asphalt-based paints in humans, but NIOSH concludes that asphaltbased paints are potential occupational carcinogens.



## Benzidine-, o-Tolidine-, and o-Dianisidine-based Dyes

In December 1980, OSHA and NIOSH jointly published the Health Hazard Alert: Benzidine-, o-Tolidine-, and o-Dianisidine-based Dyes [DHHS (NIOSH) Publication No. 81-106] (http://www.cdc.gov/niosh/81-106. html). In this Alert, OSHA and NIOSH concluded that benzidine and benzidine-based dyes were potential occupational carcinogens and recommended that worker exposure be reduced to the lowest feasible level. OSHA and NIOSH further concluded that o-tolidine and o-dianisidine (and dyes based on them) may present a cancer risk to workers and should be handled with caution and exposure minimized.



## Carbon Black

NIOSH considers “Carbon Black” to be the material consisting of more than 80% elemental carbon, in the form of near-spherical colloidal pa rticles and coalesced particle aggregates of colloidal size, that is obtained by the part ial combustion or thermal decomposition of hydrocarbons. The NIOSH REL (10-hour TWA) for carbon black is 3.5 mg/m 3 

## . Polycyclic aromatic hydrocarbons (PAHs), particulate polycyclic organic material ( PPOM), and polynuclear aromatic hydrocarbons (PNAs) are terms frequently used to describe various petroleum-based substances that NIOSH considers to be poten tial occupational carcinogens. Since some of these aromatic hydrocarbons may be formed during the manufacture of carbon black (and become adsorbed on the carbon black), the NIOSH REL (10-hour TWA) for carbon black in the presence

of PAHs is 0.1 mg PAHs/m 3 

## (measured as the cyclohexane-extractable fraction). The OSHA PEL (8-hour TWA) for carbon black is 3.5 mg/m 3



## . 

## Chloroethanes

NIOSH considers the following four chemicals to be potential occupational carcinogens:

● 

## Ethylene dichloride ● 

## 1,1,2,2-Tetrachloroethane

● 

## Hexachloroethane ● 

## 1,1,2-Trichloroethane

Additionally, NIOSH recommends that the follo wing five other chloroethane compounds be treated in the workplace with caution because of their structural similarity to the four chloroethanes shown to be carcinogenic in animals:

● 

## 1,1-Dichloroethane ● 

## Methyl chloroform ● 

## 1,1,1,2-Tetrachloroethane

● 

## Ethyl chloride ● 

## Pentachloroethane



## Chromic Acid and Chromates (as CrO 3 

## ), Chromium(II) and Chromium(III) Compounds (as Cr), and Chromium Metal (as Cr)

The NIOSH REL (10-hour TWA) is 0.001 mg Cr(VI)/m 3 

## for all hexavalent chromium [Cr(VI)] compounds. NIOSH considers all C r(VI) compounds (including chromic acid, tert-butyl chromate, zinc chromate, and chromyl chloride) to be potential occupational carcinogens. The NIOSH REL (8 -hour TWA) is 0.5 mg Cr/m 3 

## for chromium metal and chromium(II) and chromium(III) compounds.

The OSHA PEL is 0.005 mg CrO 3 

## /m 3 

## (8-hour TWA) for chromic acid and chromates (including tert-butyl chromate with a “skin” designation and zinc chromate); 0.5 mg Cr/m 3 

## (8- hour TWA) for chromium(II) and chromium(III) compounds; and 1 mg Cr/m 3 

## (8-hour TWA) for chromium metal and insoluble salts.



## Coal Dust and Coal Mine Dust

The NIOSH REL (10-hour TWA) for respirable coal mine dust is 1 mg/m 3 

## , measured using a coal mine personal sampler unit (CPSU) as define d in 30 CFR 74.2. The REL is equivalent to 0.9 mg/m 3 

## measured according to the ISO/CEN/ACGIH (International Standards Organization/ Comité Européen de Normalisation/American Conference of Governmental Industrial Hygienists) definition of respirable dust. The REL applies to respirable coal mine dust and respirable coal dust in occupations other than mining. NIOSH recommends a separate REL for crystalline silica. See NIOSH publication 95-106 ( Criteria for a Recommended Standard - Occupational Exposure to Respirable Coal Mine Dust ) for more detailed information.



## Coal Tar Pitch Volatiles

NIOSH considers coal tar products (i.e., coal tar, coal tar pitch, or creosote) to be potential occupational carcinogens; the NIOSH REL (10-hour TWA) for coal tar products is 0.1 mg/m 3 

## (cyclohexane-extractable fraction).

The OSHA PEL (8-hour TWA) for coal tar pitch volatiles is 0.2 mg/m 3 

## (benzene-soluble fraction). OSHA defines “coal tar pitch volatiles” in 29 CFR 1910.1002 as the fused polycyclic hydrocarbons that volatilize from the distillation re sidues of coal, petroleum (excluding asphalt),

## Coke Oven Emissions

The production of coke by the carbonization of bituminous coal leads to the release of chemically-complex emissions from coke ovens th at include both gases and particulate matter of varying chemical composition.

NIOSH recommends reducing exposures to cotton dust to the lowest feasible concentration to reduce the prevalence and severity of byssinosis; the REL is <0.200 mg/m 3 

## (as lint free cotton dust).

As found in OSHA Table Z-1 (29 CFR 1910. 1000), the PEL for cotton dust (raw) is 1 mg/m 3 

## for the cotton waste processing operations of waste recycling (sorting, blending, cleaning, and willowing) and garnetting. PELs for other sectors (as found in 29 CFR 1910.1043) are 0.200 mg/m 3 

## for yarn manufacturing and cotton washing operations, 0.500 mg/m 3 

## for textile mill waste house operations or for dust from “lower grade washed cotton” used during yarn manufacturing, and 0.750 mg/m 3 

## for textile slashing and weaving operations. The OSHA standard 29 CFR 1910.1043 does not apply to cott on harvesting, ginning, or the handling and processing of woven or knitted materials and wash ed cotton. All PELs for cotton dust are mean concentrations of lint-free, respirable cotton dust collected by a vertical elutriator or an equivalent method and averaged over an 8-hour period.



## Lead

NIOSH considers “Lead” to mean metallic l ead, lead oxides, and lead salts (including organic salts such as lead soaps but excluding l ead arsenate). The NIOSH REL for lead (8-hour TWA) is 0.050 mg/m 3 

## ; air concentrations should be maintained so that worker blood lead remains less than 0.060 mg Pb/100 g of whole blood.

OSHA considers “Lead” to mean metallic lead , all inorganic lead compounds (lead oxides and lead salts), and a class of organic com pounds called soaps; all other lead compounds are excluded from this definition. The OSHA PEL (8-hour TWA) is 0.050 mg/m 3 

## ; other OSHA requirements can be found in 29 CFR 1910.1025. The OSHA PEL (8 hour-TWA) for lead in “non-ferrous foundries with less than 20 employees” is 0.075 mg/m 3



## .



## Mineral Dusts

The OSHA PELS for “mineral dusts” listed below are from Table Z-3 of 29 CFR 1910.1000. The OSHA PEL (8-hour TWA) for crystalline silica (as respirable quartz) is either 250 mppcf divided by the value “%SiO 2 

## + 5” or 10 mg/m 3 

## divided by the value

# Appendix C (Continued) SUPPLEMENTARY EXPOSURE LIMITS

“%SiO 2 

## + 2.” The OSHA PEL (8-hour TWA) for crystalline silica (as total quartz) is 30 mg/m 3 

## divided by the value “%SiO 2 

## + 2.” The OSHA PELs (8-hour TWAs) for cristobalite and tridymite are 1⁄2 the values calculated above using the count or mass formulae for quartz.

The OSHA PEL (8-hour TWA) for amorphous silica (including diatomaceous earth) is either 80 mg/m 3 

## divided by the value “%SiO 2 

## ,” or 20 mppcf.

The OSHA PELs (8-hour TWAs) for talc (not containing asbestos), mica, and soapstone are 20 mppcf. The OSHA PEL (8-hour TWA) for portland cement is 50 mppcf. The OSHA PEL (8-hour TWA) for graphite (natural) is 15 mppcf. The PELs for talc (not containing asbestos), mica, soapstone, and portland cement are applicab le if the material contains less than 1% crystalline silica.

The OSHA PEL (8-hour TWA) for coal dust (as the respirable fraction) containing less than 5% SiO 2 

## is 2.4 mg/m 3 

## divided by the value “%SiO 2 

## + 2.” The OSHA PEL (8-hour TWA) for coal dust (as the respirable fraction) containing greater than or equal to 5% SiO 2 

## is 10 mg/m 3 

## divided by the value “%SiO 2 

## + 2.”



## NIAX® Catalyst ESN

In May 1978, OSHA and NIOSH jointly published Current Intelligence Bulletin (CIB) 26: NIAX® Catalyst ESN . In this CIB, OSHA and NIOSH recommended that occupational exposure to NIAX® Catalyst ESN, its compone nts, dimethylaminopropionitrile and bis(2-(dimethylamino)ethyl)ether, as well as fo rmulations containing either component, be minimized. Exposures should be limited to as few workers as possible, while minimizing workplace exposure concentrations with effectiv e work practices and engineering controls. Exposed workers should be carefully monitored for potential disorders of the nervous and genitourinary system. Although substitution is a possible control measure, alternatives to NIAX® Catalyst ESN or its components should be carefully evaluated with regard to possible adverse health effects.



## Trichloroethylene

NIOSH considers trichloroethylene (TCE) to be a potential occupational carcinogen and recommends a REL of 2 ppm (as a 60-minute ceiling) during the use of TCE as an anesthetic agent, and 25 ppm (as a 10-hour TWA) during all other exposures.



## Tungsten Carbide (Cemented)

“ Cemented tungsten carbide” or “hard metal” refers to a mixture of tungsten carbide, cobalt, and sometimes metal oxides or carbides and other me tals (including nickel). When the cobalt (Co) content exceeds 2%, its contribution to th e potential hazard is judged to exceed that of tungsten carbide. Therefore, the NIOSH REL (10-hour TWA) for cemented tungsten carbide containing >2% Co is 0.05 mg Co/m 3 

## ; the applicable OSHA PEL is 0.1 mg Co/m 3 

## (8-hour TWA). Nickel (Ni) may sometimes be used as a binder rather than cobalt. NIOSH considers cemented tungsten carbide cont aining nickel to be a potential occupational carcinogen and recommends a REL of 0.015 mg Ni/m 3 

## (10-hour TWA). The OSHA PEL for Insoluble Nickel (i.e., a 1 mg Ni/m 3 

## 8-hour TWA) applies to mixtures of tungsten carbide and nickel.

# Appendix D SUBSTANCES WITH NO ESTABLISHED RELs

After reviewing available published litera ture, NIOSH provided comments to OSHA on August 1, 1988, regarding the “Proposed Rule on Air Contaminants” (29 CFR 1910, Docket No. H-020). In these comments, NIOSH questioned whether the PELs proposed (and listed below) for the following substances included in the Pocket Guide were adequate to protect workers from recognized health hazards. The current PEL for each of these compounds is listed on the chemical page for each substance in the Pocket Guide . See pages xi-xii for a discussion of the vacated PELs.

• Acetylene tetrabromide [ TWA 1 ppm]

• Chlorobenzene [ TWA 75 ppm]

• Ethyl bromide [ TWA 200 ppm, STEL 250 ppm]

• Ethylene glycol [ C 50 ppm]

• Ethyl ether [ TWA 400 ppm, STEL 500 ppm]

• Fenthion [ TWA 0.2 mg/m 3 

## (skin)]

• Furfural [ TWA 2 ppm (skin)]

• 2-Isopropoxyethanol [ TWA 25 ppm]

• Isopropyl acetate [ TWA 250 ppm, STEL 310 ppm]

• Isopropylamine [ TWA 5 ppm, STEL 10 ppm]

• Manganese tetroxide (as Mn) [ TWA 1 mg/m 3 

## ]

• Molybdenum (soluble compounds as Mo) [ TWA 5 mg/m 3 

## ]

• Nitromethane [ TWA 100 ppm]

• m-Toluidine [ TWA 2 ppm (skin)]

• Triethylamine [ TWA 10 ppm, STEL 15 ppm]

At that time, NIOSH also conducted a limited ev aluation of the literature and concluded that the documentation cited by OSHA was inadequate to support the proposed PEL (as an 8-hour TWA) of 10 mg/m 3 

## for the compounds listed below. The current PEL for magnesium oxide fume is 15 mg/m 3 

## (8-hour TWA, total particulate), and the current PEL for molybdenum (insoluble compounds as Mo) is 15 mg/m 3 

## (8-hour TWA, total dust). For the other compounds listed below the current PEL is 15 mg/m 3 

## (8-hour TWA, total dust) and 5 mg/m 3 

## (8-hour TWA, respirable dust).

• α -Alumina

• Benomyl

• Emery

• Glycerine (mist)

• Graphite (synthetic)

• Magnesium oxide fume

• Molybdenum (insoluble compounds as Mo)

• Particulates not otherwise regulated

• Picloram

Definitions for Type C and Type CE Respirators

The definitions below were obtained from the NIOS H Certified Equipment List, which is available on the NIOSH Web site (http://www.cdc.gov/niosh/npptl/topics/respirators/cel).

Type C Respirator: An airline respirator, for entry into and escape from atmospheres not immediately dangerous to life or health, which consists of a sour ce of respirable breathing air, a hose, a detachable coupling, a control valve, orifice, a demand valv e or pressure demand valve, and arrangement for attaching the hose to the wearer and a facepiece, hood, or helmet.

Type CE Respirator: A Type C supplied-air respirator equi pped with additional devices designed to protect the wearer's head and neck against impact and abrasion from rebounding abrasive material, and with shielding material such as plastic, glass, w oven wire, sheet metal, or other suitable material to protect the window(s) of facepieces, hoods, and helmets which do not unduly interfere with the wearer's vision and permit easy access to the exte rnal surface of such window(s) for cleaning.

# Appendix F MISCELLANEOUS NOTES

Benzene

The final OSHA Benzene standard in 1910.1028 applies to all occupational exposures to benzene except some subsegments of industry where exposures are consistently under the action level (i.e., distribution and sales of fuels, seal ed containers and pipelines, coke production, oil and gas drilling and production, natural gas processing, and the percentage exclusion for liquid mixtures); for the excepted subsegments, the benzene limits in Table Z-2 apply (i.e., an 8-hour TWA of 10 ppm, an acceptable ceiling of 25 ppm, and 50 ppm for a maximum duration of 10 minutes as an acceptable maximum peak above the acceptable ceiling).

Octachloronaphthalene Pentachloronaphthalene Tetrachloronaphthalene Trichloronaphthalene

IDLH values for these four chloronaphthalene compounds are unknown. The Documentation for Immediately Dangerous to Life or Health Concentrations (NTIS Publication Number PB-94-195047) identified “Effective” IDLH values, based on analogy with other chloronaphthalenes and the then-effective NIOSH Respirator Decision Logic (DHHS [NIOSH] Publication No. 87-108; http:// www.cdc.gov/niosh/docs/ 87-108). These values for respirator recommendations were determined by multip lying the NIOSH REL or OSHA PEL by an assigned protection factor of 10. This assigned protection factor was used during the Standards Completion Program for deciding when the “most pr otective” respirators should be used for these four chemicals. Listed below are the “Effective” IDLH values that were determined using 10 times the REL or PEL for each chemical. For more information please consult the IDLH Documentation on the NIOSH Web site (http://www.cdc.gov/niosh/idlh/idlh- 1 .html).
