12. Class F - Dangerously Reactive Material
Hazard/Danger
Very unstable
React with water to give
off toxic gas
Undergoes polymerization/
decomposition
a. Why are Class F - Dangerously Reactive Materials unstable?
- Polymerization - addition, condensation
- Decomposition
- Self-reactive - shock, increased temperature or
pressure
b. How are Class F materials used safely?
- Read all the information on the label/MSDS.
- Follow the safe operating instructions.
- Be aware of the hazards.
- Take measures to eliminate or control the hazards.
13. Material Safety Data Sheet (MSDS)
a. What is a material safety data sheet (MSDS)?
- A supplier document that gives important information on the safe use of the
product.
- Lists hazardous ingredients > 1%
- List carcinogens/reproductive toxins > 0.1%
- Update MSDS every 3 years or in 6 months - if new health info available
b. What information is found in a MSDS
- hazardous ingredients
- product identification
- physical information
- fire & explosion hazard
- reactivity information
- health hazard information
- preventive measures
- first aid measures
- preparation information
c. The employer’s responsibility on MSDS’s
Have a MSDS
for each controlled
product
Make the MSDS’s
readily available
Educate workers
on using MSDS’s
