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
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
When evaporating a mixture of chemicals, the chemical having the lowest TWA will be used to determine if the mixture meets the guidelines.
