OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY 

Tot. # of workers exposed via assessed routes: 4 

Basis: Submission estimates 10 workers/site. CEB conservatively assumes all 

workers exposed to the PMN 

Inhalation: 

Negligible exposure to vapors expected (VP <0.001 torr); however, exposure to 

dust is possible. 

Exposure to Particulate (Class I) 

Typical: 6.0E-2 mg/day over 20 days/yr 
Worst Case: 2.0E-1 mg/day over 20 days/yr 

Number of workers (all sites) with inhalation exposure: 4 

Basis: 

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? 1-2 No 

Inhalation Monitoring Data Desired? No 

Dermal: 

Exposure to Solid at % concentration 

High End: 3.1E+3 mg/day over 20 days/yr
