Air contaminants

Topic index


Air contaminants are particles, liquids, and gases in the air that can be harmful to your health if you breathe them in, swallow them, or get them on your skin.

Oregon OSHA requires employers to set exposure limits for many air contaminants; you’ll find them in three “Z tables” in Oregon Rules for Air Contaminants (437-002-0382). Table Z-1 includes all of the air contaminants that have Oregon OSHA exposure limits. Notes for some air contaminants in Table Z-1 refer you to Table Z-2, Table Z-3, or other Oregon OSHA requirements.

There are similar tables in Oregon OSHA’s construction rules and agriculture rules.
