"Minimize all chemical exposures."

	Minimize all chemical exposures.
	Avoid underestimating the risk.
	Provide adequate ventilation.
	Institute a Chemical Hygiene Program.
	Observe the PEL’s or TLV’s
	Observe all the rules of safety.

"PEL = Permissible Exposure Limit..."

	PEL = Permissible Exposure Limit (OSHA)
	TLV = Threshold Limit Value (ACGIH)

"PEL’s and TLV’s are airborne..."

	PEL’s and TLV’s are airborne concentrations of chemicals set as limits, which are generally considered safe for the average worker.
	These limits are based on an average eight work hours in an average forty hours work week.
	PEL’s are exposure levels regulated by OSHA, whereas TLV’s are exposure guidelines suggested by the American Conference of Governmental Industrial Hygienists (ACGIH)

"PEL’s and TLV’s can also..."

	PEL’s and TLV’s can also be based on a fifteen minute exposure, which is called STEL (Short Term Exposure Limit).
	There can also be a limit based on a maximum exposure with no time average, which is called Ceiling.
