the operation process, and workers to determine the evaluation procedure necessary.
USAEHA, Industrial Hygiene Division, may be contacted for information concerning
hazard evaluation or detailed sampling instructions.
d. Medical Risk Assessment Code and Occupational Health Hazard
Abatement. Risk assessment codes must be assigned to every hazard evaluated in
accordance with DODI 6055.1 and AR 385-10. Risk assessment codes(s) are used to
prioritize funding for corrective action at all levels. Hazards with a RAC of 1 or 2 must
be controlled before funding lesser hazards. Risk assessment codes generated by the
industrial hygienist must reflect a comprehensive evaluation of the particular health
hazard to include sampling (if warranted). Identified health hazards (which have been
sufficiently assessed) will be entered into the installation abatement plan by written
report to the local DA OSH manager. AR 385-10 contains detailed information on
hazard abatement procedures.
e. Record Keeping.
(1) A record must be kept on all IH activities, to include health hazard
inventories, evaluations of hazards, existing health hazard control measures, and
recommendations for improvements. Records should be maintained in bound
notebooks or other permanent documents. All records must comply with DOD and
OSHA standard requirements. Department of Defense policy is to maintain all records
for 40 years. Records of worker exposures must be maintained in such form that they
can be included in the worker medical record and used to apprise the worker of
exposures. Data, which show no worker exposure, are as important, if not more so,
than exposure data and the relationship of the period sampled to the employee's
exposure for the shift(s) sampled must also be documented. Full shift samples are the
best way to accomplish this.
(2) Records of toxic chemicals used and records of hazardous devices or
processes should be kept so those potential problems may be identified. These records
should be kept as part of HHIM. Ventilation flow rates, noise levels, and process
variables should also be maintained to show effects of control measures.
f. Design Review. A thorough review of the plant, process and operational
changes, and new design can prevent many potential OSH problems. The local IH staff
should be in the design review process for all installation activities. In areas of highly
technical or unusual designs, USAEHA can be requested to provide assistance.
AR 420-10 is the authority for medical review.
g. Respiratory Protection. An ongoing Respiratory Protection Program must
meet all the OSHA standards. Supervisory, safety, and preventive medicine personnel
should jointly develop an installation program that meets legal requirements. Detailed
program information can be found in OSHA standards, AR 11-34, USAEHA Technical
Guide (TG) 171, and the NIOSH Guide to Respiratory Protection. Respiratory
Protection will be discussed in detail in another lesson.
