project scope
Project Scope
  • Review IH Historical exposure monitoring records
  • Review chemical use by process
  • Establish a worker exposure matrix inventory by
    • Division
    • Process & Unit Operation
    • Exposure Point & Chemical Use
    • Chemical Agent (MeCl2, isocyanates, etc.)
  • Prioritize exposure points for monitoring
  • Assess regulatory compliance (CSI 400 and OSHA)
  • Design sampling program
scope of study
Scope of Study
  • Battery Manufacturing (1 building, 1 process)
  • Reagent Manufacturing Operations (1 building, 30 processes)
  • Film Assembly Operations (2 buildings)
  • Power Boiler Plants
  • Other
  • Chemical Operations (3 buildings, 200 processes)
  • Sheet Coating Operations (3 Buildings, 35 processes)
  • Negative Coating Operations (2 buildings, 5 processes)
exposure assessment strategy
Exposure Assessment Strategy
  • Basic characterization
  • Exposure assessment
  • Prioritize exposures
  • Recommendations
basic characterization
Basic Characterization
  • Review past monitoring data
  • Initial tour of facility
    • Approach by chemical, process, similar exposure group
    • Where/when to focus subsequent visits
  • Obtain chemical list, process information, MSDS’s. SOP’s, exposure guidelines, workforce information.
exposure assessment
Exposure Assessment
  • Supervisor/employee interviews
  • Subsequent tours:
    • Engineering controls
    • Observe, observe, observe
    • Document exposure points
    • Estimate exposure ratings
prioritize exposures
Prioritize Exposures
  • Assign exposure ratings
  • Assign toxicity rating
  • Calculate priority rating
  • Use ratings and professional judgment to determine monitoring plan
exposure rating
Exposure Rating

Both inhalation and skin exposures are expected to be negligible [< 10 % of the Polaroid Exposure Guideline (PEG)]i.e. closed system with no potential for release to the work area.

Both inhalation and skin exposures are expected to be low (11-25% of PEG)i.e. working around closed systems with potential for release at identified points.

There is a potential for moderate inhalation and/or skin exposures (25-50% of PEG) i.e. manual handling of materials with low to moderate volatility/dustiness

There is a potential for high inhalation and/or skin exposures (51-99% of PEG) i.e. sampling or packaging high volatility materials without sufficient local ventilation

Frequent contact or exposure to the agent at very high concentrations (>100 % of the PEG)

Description

Very Low (1)

PEG = 100 ppm or 10 mg/m3

Low (2)

PEG = 50-100 ppm or 5-10 mg/m3

Moderate (3)

PEG = 5-50 ppm or 0.5-5 mg/m3

High (4)

PEG = 0.5-5 ppm or 0.05-0.5 mg/m3

Very High (5)

PEG < 0.5 ppm or 0.05 mg/m3
