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). Chemicals not listed by NIOSH in the Pocket
Guide must be approved by Labconco’s 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.
Use of Chemical Carcinogens in
the FilterMate
Selected carcinogens may be used safely in the FilterMate under
the following restrictions.
The use of a vented hood or vented enclosure is
always the preferred method when working with
carcinogens. The FilterMate should only be used
as a last resort when venting is not an option.
The potential carcinogens are listed in the
NIOSH Pocket Guide to Chemical Hazards as
“Ca.” Each potential carcinogen must have a
TWA of 1 or greater; have minimum respirator
recommendation of Escape GMFOV, and an
odor threshold significantly lower than the TWA
for the chemical.
The inlet concentration or the evaporation rate
of the chemical must never exceed the TWA for
the chemical.
