Name 4 types of effects that hazardous mixtures can have on your body.
PEL - Permissible Exposure Limit
Legal limit in the United States for exposure of an employee to a chemical substance or physical agent and established by the OSHA.
For chemicals, the chemical regulation is usually expressed in parts per million (ppm), or sometimes in milligrams per cubic meter (mg/m3).
A PEL is usually given as a time-weighted average (TWA), although some are short-term exposure limits (STEL) or ceiling limits.
TLV- Threshold Limit Value
Level to which a worker can be exposed day after day for a working lifetime without adverse effects. The TLV is an estimate based on the known toxicity in humans or animals of a given chemical substance. TLV are values established by a professional organization and are not law.
A chemical added to slow down or speed up a chemical reaction.
A substance that spontaneously ignites when exposed to air is considered?
