What are the types of fire extinguishers

What is

Class A,B and C

200

Name different ways to recognize potential health hazards

What is

•Visible material in the air – If you see a visible cloud of vapor or particles, there maybe an exposure potential.

•Settled Dust – Chemical dust on the ground or other surfaces, it probably got there by settling out of the air.  If disturbed, settled dust can become airborne again.

•Odor – If you smell a chemical, you are inhaling it.  However some chemicals can be smelled at levels well below those that are harmful.
