Commands with highlyhazardous chemicals, at or above the specified thresholdquantities defined in the American Conference of GovernmentalIndustrial Hygienists (ACGIH) Manual, Industrial Ventilation, AManual of Recommended Practice, shall develop plans documentingsystematic analyses of potential hazards for every step in theirchemical processes. This plan shall include safe operatingprocedures, training requirements on specific safety and healthhazards, emergency operations, safe work practices, inspectionand maintenance, and mishap investigation and reportingprocedures. Commands shall review any contractor’s safetyrecords regarding these chemicals before entering intocontracts.17005. VENTILATION. In areas where injurious air contaminantsare routinely generated by fixed installations, permanentexhaust or ventilation systems shall be provided. The ACGIHIndustrial Ventilation Manual will be used as the standard forindustrial ventilation designs where applicable. At temporarywork sites or for interim measures, portable ventilationequipment may be used. Contaminants will not be exhausted intoareas that could endanger others. If flammable atmospheres arebeing removed, the ventilation equipment selected must belabeled by the manufacturer as explosion-proof or intrinsicallysafe. All industrial ventilation systems must be evaluated andapproved by the responsible safety manager, industrialhygienist, environmental manager, and fire department.17006. HEALTH HAZARDS1. Due to the variety and diversity of hazardous or potentiallyhazardous substances available for use, an overview of healthhazards is presented here in a generalized manner.
