Threshold Limit Values (TLV) and Immediately Dangerous to Life and Health (IDLH) values
Matheson Tri-Gas assumes no responsibility for the accuracy of the informationlisted. As TLV and IDLH values may change, the current Substance guidelines from the following sources should be consulted for Fluorine up-to-date accuracy. Formaldehyde Sources: TLV-TWA and TLV-STELdata extracted from the 2005 Threshold Limit Values & Biological Exposure Indices, copyright 2005 by the American Conference of Formic Acid Furfural Governmental Industrial Hygienists (ACGIH). IDLHvalues extracted from the NIOSH Pocket Guide to Chemical Hazards, 2004 published by the National Institute Gasoline for Occupational Safety and Health (NIOSH).
