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.”
![Page 4: OSHA in the Laboratory](https://reader036.fdocuments.us/reader036/viewer/2022062517/5681354f550346895d9cac3f/html5/thumbnails/4.jpg)
OR-OSHA inspection
What’s the most hazardous chemical you work with?
What are the hazards (what can it do to you)?
![Page 5: OSHA in the Laboratory](https://reader036.fdocuments.us/reader036/viewer/2022062517/5681354f550346895d9cac3f/html5/thumbnails/5.jpg)
Chemical Hygiene Plan
Responsibilities Laboratory CHP Laboratory Chemicals Exposure Sampling Safety Controls Employee Training
Special Precautions Medical Surveillance Laboratory Accidents Laboratory Audits Chemical Inventory Recordkeeping
Based on OSU’s plan (template on EH&S website)

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

SDS – What is it Good For?
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

Chemical Classifications
Know about general hazards Check on specific hazards Handling solvents Handling acids/bases
![Page 10: OSHA in the Laboratory](https://reader036.fdocuments.us/reader036/viewer/2022062517/5681354f550346895d9cac3f/html5/thumbnails/10.jpg)
Health Effects - Chemical Categories
Aromatic hydrocarbons – irritant, CNS benzene
Aldehydes – irritant formaldehyde
Straight-chain hydrocarbons – irritant, CNS
Alcohols – irritant methanol
Esters - irritant

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

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

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

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

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

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