Introduction

Section B. NIOSH RELs and General Recommendations for Safety and Health

This section contains three tables listing occupational hazards and the NIOSH RELs and general
recommendations for safety and health. Table 1 lists chemical hazards, Table 2 presents physical hazards,
and Table 3 contains industry, process, and work environment hazards. Health effects cited in Tables 1 and
2 are those generally associated with the hazard; they are for humans unless otherwise noted. Consult the
primary sources listed in Section A for definitive information. The Chemical Abstracts Service (CAS)
number and the Registry of Toxic Effects of Chemical Substances (RTECS) number are included in Table 1
where appropriate.

Appendix I. Classes of Chemicals

Scveral RELs apply to entire classes of chemicals. Appendix I lists these classes (e.g., alkanes, ketones, etc.)
and the individual members of each that are listed by RTECS. Table 1 of Section B refers the reader to
Appendix I whenever a class name is mentioned. Readers may use the class name to locate source
documents in Section A.

Appendix Il. Chemicals for Which NIOSH Adopted RELs During the OSHA PEL
Project

Appendix II lists chemicals for which NIOSH adopted exposure limits on the basis of their comments during
the OSHA PEL Project. These RELs are included in Table 1 of Section B. For further information about
these chemicals, readers should refer to OSHA’s final rule on air contaminants in the Federal Register

[54 FR 2641 (1989)] and to the 1988 NIOSH testimony on OSHA’s proposed rule on air contaminants [NTIS
No. PB-91-115-337].

Appendix Ill. Chemicals for Which NIOSH Did Not Adopt RELs During the OSHA
PEL Project

Appendix III lists chemicals for which NIOSH did not adopt RELs during the OSHA PEL Project. After a
limited review of these chemicals, NIOSH concluded that adverse health effects could occur at the proposed
OSHA PELs.

Appendix IV. Chemicals for Which NIOSH Revised Existing RELs During the
OSHA PEL Project

Appendix IV lists chemicals for which NIOSH revised existing RELs during the OSHA PEL Project. These
chemicals are listed with their previous and current RELs.

Appendix V. Categories of Pesticides

Appendix V lists pesticides according to three categories of toxicity defined in the 1978 NIOSH criteria
document on pesticides (Criteria for a Recommended Standard: Occupational Exposure During the
Manufacturing and Formulation of Pesticides, DHEW (NIOSH) Publication No. 78-174, NTIS No.
PB-81-227-001). Many of the chemicals listed as pesticides have other applications and are presented in
Sections A and B.

Recommended exposure limit. RELs are occupational exposure limits
recommended by NIOSH as being protective of worker health and safety over a
working lifetime. The REL is used in combination with engineering and work
practice controls, exposure and medical monitoring, labeling, posting, worker
training, and personal protective equipment. This limit is frequently expressed as a
time-weighted average (TWA) exposure for up to 10 hr/day during a 40-hr
workweek. The REL may also be expressed as (1) a short-term exposure limit
(STEL) that should never be exceeded and is to be determined in a specified
sampling time (usually 15 min), or (2) a ceiling limit that should never be exceeded
even instantaneously unless specified over a given time period.

Registry of Toxic Effects of Chemical Substances

The notation "skin" indicates that airborne or direct exposure by the cutaneous
route (including mucous membranes and eyes) contributes to overall exposure.

Short-term exposure limit. Unless otherwise noted, the STEL is the 15-min TWA
exposure that shall not be exceeded at any time during a workday.

Compendium of Policy Documents

. NIOSH publications (criteria documents, CIBs, Alerts, Special Hazard Reviews, Occupational
Hazard Assessments, and miscellaneous statements and reports)

. Written testimony from NIOSH about rules proposed by regulatory agencies such as OSHA, MSHA,
or the U.S. Environmental Protection Agency (EPA)

. Testimony presented by NIOSH at regulatory hearings convened by OSHA or MSHA

These documents are described here briefly and are available through NIOSH or the National Technical
Information Service (NTIS).”

Criteria Documents. —Criteria documents are developed to provide the basis for the comprehensive
occupational safety and health standards sought by congress. These documents generally contain a critical
review of the scientific and technical information available on the prevalence of hazards, the existence of
safety and health risks, and the adequacy of methods to identify and control hazards. Recommendations for
minimizing safety and health risks include medical monitoring, exposure assessment, worker training, control
technology, personal protective equipment, and recordkeeping as well as RELs where appropriate. Criteria
documents are developed primarily for the U.S. Department of Labor (OSHA and MSHA), however, they
are also distributed to health professionals in academia, industry, organized labor, public interest groups, and
other Federal, State, and local government agencies.

Current Intelligence Bulletins (CIBs). —CIBs review and evaluate new and emerging information about
occupational hazards. A CIB may draw attention to a previously unrecognized hazard, report new data on a
known hazard, or disseminate information about hazard control. These documents are distributed to
representatives of academia, industry, organized labor, public health agencies, and public interest groups as
well as to Federal agencies responsible for ensuring the safety and health of workers.

Alerts. —NIOSH Alerts briefly present new information about occupational illnesses, injuries, and deaths.
Alerts urgently request assistance in preventing, solving, and controlling newly identified occupational
hazards. Workers, employers, and safety and health professionals are asked to take immediate action to
reduce risks and implement controls.

Special Hazard Reviews, Occupational Hazard Assessments, and Miscellaneous Statements
and Reports. —Special Hazard Reviews, Occupational Hazard Assessments, and miscellaneous statements
and reports are other types of NIOSH documents that complement NIOSH recommendations for standards.
These documents assess safety and health problems and recommend appropriate methods for control and
monitoring. Although these documents do not supplant the more comprehensive criteria documents, they
are prepared to assist OSHA or MSHA in the formulation of regulations.

Responses to Regulatory Agencies. —NIOSH periodically presents written comments and testimony
before Congressional committees and at regulatory hearings convened by OSHA or MSHA. The testimony
always includes the current NIOSH policy concerning the hazard in question.

INTRODUCTION

PURPOSE

This document was developed to provide a comprehensive list of National Institute for Occupational Safety
and Health (NIOSH) documents that contain recommendations for safety and health standards in the
workplace. Our intention is to make this information conveniently available to workers, employers,
occupational health professionals, and union representatives.

BACKGROUND

Under the authority of the Occupational Safety and Health (OSH) Act [29 USC 1900] and the Mine Safety:
and Health Act [30 USC 80], NIOSH develops and recommends criteria for preventing disease and
hazardous conditions in the workplace. NIOSH recommended exposure limits (RELs) are examples of such
criteria, NIOSH also recommends preventive measures (e.g., engineering controls, safe work practices,
personal protective equipment, and environmental and medical monitoring) for reducing or eliminating the
adverse health effects of these hazards. To formulate these recommendations, NIOSH evaluates all relevant
scientific information about a given hazard. The recommendations are then transmitted to the Occupational
Safety and Health Administration (OSHA) and the Mine Safety and Health Administration (MSHA) of the
U.S. Department of Labor for use in promulgating legal standards. These recommendations are generally
published in criteria documents, Current Intelligence Bulletins (CIBs), Alerts, Special Hazard Reviews,
Occupational Hazard Assessments, and responses to regulatory agencies (see page 2 for a description of
these documents).

SCOPE

This document contains two major sections, A and B. Section A lists all NIOSH documents containing
recommendations for chemical, physical, and other hazards in the workplace. Section B contains the NIOSH
RELs for all of these hazards as well as the adverse health effects for the chemical and physical hazards.
Five appendices contain additional information about (1) classes of chemicals and (2) RELs adopted or
revised during OSHA rulemaking activity in 1988.”

Section A. Documents Containing NIOSH Recommendations for Safety and
Health

This section lists all NIOSH documents that contain recommendations for safety and health standards in the
workplace. These documents are listed by publication date under the occupational hazard they discuss.
Each occupational hazard is arranged alphabetically. The types of documents included are as follows:

“This activity is referred to hereafter as the OSHA PEL Project. The final rule was published in the
Federal Register on January 19, 1989 [54 FR 2329-2984 (1989)}.

APPENDIX V

CATEGORIES OF PESTICIDES

NIOSH recommends three categories to define the toxicity of pesticides for the various routes of exposure
(oral, inhalation, and dermal). Group I contains the pesticides that pose a significant risk of (1) adverse
acute health effects at low concentrations, or (2) carcinogenic, teratogenic, neurotoxic, or reproductive
effects. Group II pesticides pose adverse acute health risks at moderate doses, and Group III pesticides pose
minimal risk of adverse acute effects even at relatively high doses. For further discussion and clarification,
refer to the 1978 NIOSH criteria document on pesticides (Criteria for a recommended standard:
occupational exposure during the manufacturing and formulation of pesticides, DHEW (NIOSH) Publication
No. 78-174, NTIS No. PB-81-227-001). Many of the chemicals listed as pesticides have other applications and
are presented in Sections A and B,
