<br />Notes: Exposure limits are California OSHA values (unless noted otherwise). If California OSHA values were not available, then NIOSH RELs or ACGIH TLVs were listed.
<br />California OSHA Permissible Exposure Limit (CA PEL)- Legally required exposure limit.
<br />NIOSH Recommended Exposure Limit (REL)- Voluntary conservative exposure limit.
<br />** ACGIH Threshold Limit Value (TLV)- Voluntary exposure limit (updated most frequently).
<br />TWA = Time Weighted Average concentrations that must not be exceeded during any 8-hour workshift during a 40-hour workweek.
<br />IDLH = Immediately Dangerous to Life or Health - a condition that poses a threat of exposure to airborne contaminants when that exposure is likely to cause death,
<br />immediate or delayed permanent adverse health effects, or prevent escape from such an environment. EVERY EFFORT SHOULD BE MADE TO EXIT IMMEDIATELY!
<br />inh = inhalation
<br />abs = absorption
<br />ing = ingestion
