Exposure Assessment 07
Exposure Assessment 07 : Medicine. Each hazard listed in the Workplace Information section is evaluated. The evaluation includes a qualitative and quantitative review of the hazard, including pertinent monitoring data, the level and frequency of exposure, and the effectiveness of existing control measures. Decisions to identify personnel for medical surveillance, to recommend additional hazard controls, or to specify exposure monitoring is based the exposure assessment. The assessment will be positive or negative. Rationale for a Negative Determination: A negative determination is issued under any, or a combination of, the conditions listed below: The worker is not exposed to the hazard because of the effective design and use of engineering controls. The worker is not exposed to the hazard at least 15 days per quarter or 30 days per year, and the hazard is not separately regulated by specific Navy or Federal standards. Based upon the results of workplace and exposure monitoring, the worker(s) are unlikely to be exposed to above the Action Level. Monitoring results of similar operations performed under similar or worse conditions were below the Action Level. The sampling size must be statistically significant. Based upon a combination of the experience of the industrial hygienist with the hazard, literature reviews, low toxicity, physical characteristics (e.g.: low volatility), limited frequency and/or duration of the job, effective and reliable use of engineering or other control measures, the worker(s) are unlikely to be exposed above the Action Level. Panel Decisions: Sometimes hazards do not fit neatly into the decision process as described above. When an industrial hygienist has difficulty in making an exposure assessment, a panel of the IH Department industrial hygienists will convene and discuss the issue. Infrequent or sub-action level exposure to OSHA or ACGIH listed carcinogens, or USN listed reproductive hazards are examples in which a panel decision might be needed to assess exposure
