  1. OSHA in the Laboratory Lance Jones Env Health & Safety

  2. Goals • OR-OSHA Inspection • Chemical Hygiene Plan • General Chemical Information • Specific Chemical Information • Chemical class • Eyewash • Spills

  3. OR-OSHA • “The employer did not provide lab employees with information and training at the time of their initial assignment to a work area where hazardous chemicals were present or prior to assignments involving new exposure situations.”

  4. OR-OSHA inspection • What’s the most hazardous chemical you work with? • What are the hazards (what can it do to you)?

  5. Chemical Hygiene Plan • Responsibilities • Laboratory CHP • Laboratory Chemicals • Exposure Sampling • Safety Controls • Employee Training Based on OSU’s plan (template on EH&S website) • Special Precautions • Medical Surveillance • Laboratory Accidents • Laboratory Audits • Chemical Inventory • Recordkeeping

  6. Chemical Hygiene Plan • Add • Inventory • Hazardous operations • Allergens, embryotoxins and teratogens • High acute or chronic toxicity • Animals, radiological, recombinant DNA • Infectious agents

  7. SDS • Safety Data Sheet - expectations • Access MSDSOnline or • File cabinets at EH&S • Chemical companies: • Sigma/Aldrich/Fluka • Mallinckrodt & JT Baker • Fisher

  8. Manufacturer name Physical characteristics Flammability Reactivity Harmful levels (PEL) Route of entry Target organs Systemic effects Signs and symptoms Exposure risks Acute Chronic PPE Control methods SDS – What is it Good For?

  9. Chemical Classifications • Know about general hazards • Check on specific hazards • Handling solvents • Handling acids/bases

  10. Health Effects - Chemical Categories • Aromatic hydrocarbons – irritant, CNS • benzene • Aldehydes – irritant • formaldehyde • Straight-chain hydrocarbons – irritant, CNS • Alcohols – irritant • methanol • Esters - irritant

  11. More Health Effects • Chlorinated solvents - CNS • dichloromethane • Amines – irritant • Toxic – mercury, lead, nickel, cadmium, arsenic, chromium • Acids & Bases – corrosive and irritant

  12. Carcinogens • Three categories: • Extreme (committee review & approval) • High (registration of use) • Moderate • Facility impacts

  13. Lab Practices • NO consumption or storage of food or drink in labs • NO handling of contact lenses, lip balm, cosmetics in labs • Keep exit paths open

  14. Hierarchy of Hazard Prevention • Engineering controls • Substitute • Enclose • Barriers • Safe work practices (CHP) • Administrative • PPE

  15. Eyewash • Requirements: • Locate any place corrosive materials are used • Cannot pass through doorway • Stays on 15 minutes • One hand operation • Weekly test • Shower

  16. PPE • Personal Protective Equipment • Types • Head • Eyes • Lungs • Skin • Feet • Levels • Glasses – goggles – face shield

  17. Spills • Prepare • Assess hazard • Get backup • Get equipment • PPE • Spill response (pads, pigs, loose) • What if you need to get help?

  18. Fire Safety • Keep exits clear • Extension cords-temporary use only • Frayed cords • Fire extinguisher use

  19. What Else? • Biohazards • Radiation hazards • Carcinogen registration • Occupational health program • Hazardous materials transportation
