immediate irreversible health effects.  IDLH concentrations should 

not be approached in the enclosure. 

Appropriate Chemicals for Odor 

Control Carbon Filters 

Below is a general set of rules to determine appropriateness of 

chemical usage. 

Selected organic chemicals considered to be 

occupational carcinogens by NIOSH can be used 

in the filtered enclosure with carbon filters 

under rigid restrictions.  See separate discussion 

on carcinogens for special instructions. 

Organics must have time weighted exposure limits (TWA) of 1 

PPM or greater. 

Chemicals must have a detectable odor at concentrations below the 

TWA for the chemical. 

Chemicals must be designated by NIOSH guidelines as acceptable 

for use with chemical cartridge-type respirators (the exception is 

formaldehyde and ammonia/amines, which used impregnated 

carbon).  Chemicals not listed by NIOSH in the Pocket Guide must 

be approved by Labconco Product Specialist (or Engineering). 

Inlet concentration must never exceed the IDLH (Immediately 

Dangerous to Life and Health) concentrations. 

Chemicals having a recommendation by NIOSH of at least 

“Escape GMFOV” (Gas Mask Full-Face Respirator). 

When evaporating a mixture of chemicals, the chemical having the 

lowest TWA will be used to determine if the mixture meets the 

guidelines. 

Call a Labconco Product Specialist at 1-800-821-5525 for 

assistance in chemical appropriateness.
