Exposure Assessment: thoughts after an ISM Audit Tim Roberts, Industrial Hygiene Jim Floyd, ALS LBNL
The Rule(10 CFR 851.21) (a) Contractors must establish procedures to identify existing and potential workplace hazards and assess the risk of associated workers injury and illness. Procedures must include methods to: (1) Assess worker exposure to chemical, physical, biological, or safety workplace hazards through appropriate workplace monitoring; (2) Document assessment for chemical, physical, biological, and safety workplace hazards using recognized exposure assessment and testing methodologies and using of accredited and certified laboratories; (3) Record observations, testing and monitoring results; (5) Evaluate operations, procedures, and facilities to identify workplace hazards; (6) Perform routine job activity-level hazard analyses; (7) Review site safety and health experience information
LBL Strategy Risk-based Use of Similar Exposure Groups (SEGs) Factoring in engineering controls OSHA Lead, Asbestos, noise, etc. DOE Notice 456.1 Nano AIHA “Occupational Exposure Assessment” model Used as a guide to good practices Based on a very new comprehensive job hazards analysis (JHA) tool
HSS View “The LBNL non-radiological exposure assessment program does not include adequate exposure assessment procedures and protocols and does not perform sufficient qualitative and quantitative exposure assessments to fully meet the requirements…”
What are the requirements? OSHA requirements are pretty clear 10 CFR 851 has some specific wording, but not fully defined DOE N 456.1 Guidance from the IH Standard, STD-6005-2001 A new Technical Standard is being developed and is scheduled to be rolled out, this year. Interpretations are mixed
Questions Tiered Approach Risk-based screening Qualitative vs. quantitative assessments when is IH Professional Judgment applicable? Role of line management vs. EHS organization
Proposed Approach 3-tiered system Hazard ID Exposure Assessment (quant.) Hazard Assessment (qualitative) Employees that will not need an Exposure Assessment
Hazard Identification Line management: Through the work planning process (JHA), workers self identify hazardous materials and agents associated with work line management verification step EHS: Checks of the chemical inventory program Walkthroughs Response to employee (or supervisor) evaluation requests On-going review of new regulations/requirements
Criteria for Assessment Priority for evaluation is based on overall risk: Presumed exposure Inherent hazard(s) of material e.g., Carcinogen, Sensitizer, Reproductive Toxin Frequency of use Quantity of material Controls (e.g., Respirators and Fumehoods or Enclosures) Employee or management requests Decision tool for quantitative assessments
Next Steps • Complete a regulatory requirements analysis 9/09 • Benchmarking 12/09
