We DO investigate health hazards DO investigate in the workplace! in (We DON’T clean teeth in factories!) DON clean (We DON’T clean toilets in factories!) DON DISEASE DISEASE What does an IH do? Inspect the workplace Inspect Identify health hazards Identify Sample the work environment Remediate and control Remediate Provide training to workers and management management Recognition of Hazards hazard assessment hazard exposure potential exposure types of hazards types chemical chemical biological biological Recognition of Hazards physical physical physiological physiological psychological psychological Evaluation of Hazards exposure assessment exposure air sampling air comparison to standards/guidelines comparison OSHA ACGIH - Control of Hazards purpose: to reduce or eliminate the hazard purpose: methods: methods: substitution substitution isolation isolation ventilation ventilation administration administration and Anticipating the Hazard by meeting with engineers by by specifying in orders by by learning from past mistakes by Where does an IH work?
