Berkeley Lab Exposure Assessment: thoughts after an ISM Audit Tim Roberts, Industrial Hygiene Jim Floyd, ALS LBNL

Berkeley Lab The Rule (10 CFR ) (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

Berkeley Lab LBL Strategy Risk-based —Use of Similar Exposure Groups (SEGs) —Factoring in engineering controls OSHA —Lead, Asbestos, noise, etc. DOE Notice —Nano AIHA “Occupational Exposure Assessment” model —Used as a guide to good practices Based on a very new comprehensive job hazards analysis (JHA) tool

Berkeley Lab 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…”

Berkeley Lab What are the requirements? OSHA requirements are pretty clear 10 CFR 851 has some specific wording, but not fully defined DOE N Guidance from the IH Standard, STD A new Technical Standard is being developed and is scheduled to be rolled out, this year. Interpretations are mixed

Berkeley Lab Questions Tiered Approach —Risk-based screening Qualitative vs. quantitative assessments —when is IH Professional Judgment applicable? Role of line management vs. EHS organization

Berkeley Lab Employees that will not need an Exposure Assessment Proposed Approach Hazard ID Exposure Assessment (quant.) Hazard Assessment (qualitative) 3-tiered system

Berkeley Lab 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

Berkeley Lab 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
