 estimating inhalation exposure; 

 3. Refinement of the media of release determinations for the various 

 release sources based on additional discussions with the submitter; 

 4. Addressing of the water release potential for each of the 

 two stages based on additional review and discussions with the submitter; 

 5. Addition of information on the use of PPE by the workers for each of 

 the two lifecycle stages; 

 6. Included results of submitter's monitoring data on lead and zirconium 

 levels in wastewater from the Lockheed Martin facility;

Gen Eqpt: Safety glasses are recommended for protection 

against exposures to dusts. Full body clothing should be 

worn to prevent potential exposure to skin. Sufficient 

mechanical ventilation (general and/or local exhaust) 

shall be provided to| maintain exposures below 

permissible air concentrations. Protective gloves 

required. 

Respirator: A NIOSH approved respirator with P100 filters 

shall be worn when airborne exposures may exceed 

OSHA/ACGIH permissible air concentrations. 

Health Effects: ACUTE: May produce eye, skin and 

respiratory tract irritation, effects on the nervous 

system and kidneys, gastrointestinal distress and anemia. 

Common symptoms are a loss of appetite, nausea, vomiting, 

stomach cramps, constipation, anxiety, difficulty in 

sleeping, fatigue, moodiness, headache, joint or muscle 

aches and decreased sexual drive. Extreme overexposure 

may lead to tremors, convulsions, paralysis, stupor, coma 

and death. // CHRONIC: Children have enhanced absorption 

and retention of ingested lead and are particularly 

sensitive to the chronic effects of lead, with slowed 

cognitive| development and reduced growth. May produce 

effects on the blood, nervous and| immune systems, blood 

pressure, kidneys as well as skin and pulmonary| 

inflammatory tissue masses, rickets-like bone deformities, 

 decreased sperm count| and spontaneous abortion. Common 

symptoms are a loss of appetite, metallic taste in the 

mouth, anxiety, constipation, nausea, pallor, fatigue, 

weakness, insomnia,| headache, nervous irritability, 

muscle and joint pain or soreness, fine tremors,| 

numbness, dizziness, hyperactivity and abdominal pain. 

Maternal overexposure| may produce low birth weight, 

birth defects and slowed postnatal neurobehavioral| 

development in the offspring. Extreme overexposure may 

lead to vomiting,| drowsiness, stupor, poor memory, 

restlessness, irritability, tremor, convulsions,| coma 

and death. Muscular weakness may develop and progress to 

paralysis| observed as "wrist-drop" and/or "foot-drop".

NOTES & KEY ASSUMPTIONS: 

Generated by the 06/07/2005 version of ChemSTEER. The PMN 

is manufactured domestically, therefore mfg, proc/use 

into piezoelectric ceramics are assessed. This PMN is 

part of a related set including P11-0270 through P11-0274. 

 All cases have the same manufacturing and proc/use and 

exhibit the same releases and exposures. Changes to the 

IRER may effect the assessment of the other 4 PMNs in the 

set. The PMN contains four elements of concern: lead, 

titanium, tungsten, and cobalt. The PMN PB rating is P3B2; 

 therefore, a full assessment is required. Releases are 

assessed to all media. Note, submission specifies several 

dust releases to stack air, which is controlled by a bag 

house. Cleaning releases are collected in a collection 

sump pit. The submission implies this pit may discharge 

or be further treated. Solids collected in the bag house 

from air emissions or from collected sump pit solids are 

sent off-site as hazardous waste every 3-5 years. 

Therefore, releases presented in this IRER to air and 

water may occur regularly; whereas land and incineration 

releases are expected to collect over time and occur 

every 3-5 years. Der

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY 

Tot. # of workers exposed via assessed routes: 

Basis: 

Inhalation: 

Submitter indiated that respirators (1/2 face respirator 

with P100 filter) are used whenever there is a potential 

for lead exposure by inhalation. 

Exposure to Mist (non-volatile) (Class I) 

Output 2: 2.9E-1 mg/day over 13 days/yr 

Number of workers (all sites) with inhalation exposure: 

Basis: Various activities (weighing, mixing and transfer 

of powder and slurries); User-defined Inhalation Model. 

Submitter indicated in supplemental information that an 

industrial hygiene plan for the site is developed each 

january for the current year. Personal lead exposure is 

always included in the plan. The sampling plan involves 

analyzing personal lead exposure for each major process 

performed in the ceramic area. The plan is based on 

activity in the area. Recent sample results for the lead 

breakup process was 13 ug/m3. Recent average sample 

result for powder fabrication for 220 kg/bt was 18 ug/m3. 

 OSHA Action level for lead is 30 ug/m3 and OSHA PEL for 

lead is 50 ug/m3. Although employees are not exposed 

above the action level for more than 30 days a year they 

still require lead levels to be measured every 6 months. 

Recent blood lead levels for two employees in the area 

EPA SANITIZED Page 5 of 9
were less than 3 mcg/d. The other employee's lead level 

wa s9 mcg/d. CEB estimate is based on 18 ug/m3 

(conservatively assumed to be an 8-hr TWA exposure). 

Chemistry report estmated that PMN material is 58-64% 

lead oxide. Calculation: 18 ug/m3 (lead)/0.61 x 1.25 

m3/hr x 8 hr/day = 0.295 mg/day. 

NOTE: The respirator class is: I. Particulate (including 

solid or liquid droplets). 

INHALATION MONITORING DATA REVIEW 

1) Uncertainty (estimate based on model, regulatory limit 

 or data not specific to industry): Yes 

2)a) Exposure level > 1 mg/day? No 

 OR 

 b) Hazard Rating for health of 2 or greater? 3 Yes 

Inhalation Monitoring Data Desired? Yes (both criteria

Dermal: 

Submitter indicated that Tyvek suits and booties are 

required whenever an employee enters the ceramic area. 

Nitrile gloves are used when working with powders. There 

are several activities when the PMN may be handled in 

liquid form. The submission indicates that the same PPE 

requirements would be in place as for liquids (Tyvek suit 

and booties, and Nitrile gloves). 

Exposure to Solid at 100.00% concentration 

High End: 3.1E+3 mg/day over 13 days/yr 

Number of workers (all sites) with dermal exposure:
