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.

Hazardous Misapplications for

Odor Control Carbon Filters with

Volatile Chemicals

There is one scenario where the accessory carbon filter misapplication would be a part of a hazardous condition. If the
