Hazardous Chemicals in Laboratories

Class A Peroxide-Forming Chemicals

These types of chemicals can form explosive levels of peroxides while sitting on the shelf.

Flammable Liquids

Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C).

Carcinogens

Carcinogens are substances and exposures that can cause cancer.

The primary function of a fume hood or chemical fume hood is to protect laboratory employees. Using a fume hood properly assists with containing spills, providing shielding, removing odors, and reducing the concentration of flammable vapors. 

Anything that involves working with volatile materials should take place inside the fume hood. Working within the fume hood will ensure the contaminated air is moved completely away from the work area.
