1. The inlet concentration of vapors is greater than the TWA.

2. The carbon filter becomes saturated.

3. The ventilation of the room is insufficient to dilute the exhaust of the

enclosure to below the TWA for the chemical.

When the inlet concentration is greater than the TWA, extra measures must be
taken to monitor the filter and number of room air exchanges.

Chemical Carcinogen Use with Odor Control Carbon

Filters

Selected carcinogens may be used safely with Odor Control carbon filters under
the following restrictions.

The use of a vented fume hood or ventilated enclosure with
ducting to the outside is always the preferred method when
working with carcinogens. The Odor Control carbon filters
should only be used, as a last resort when venting to the outside is
not an option. Another option is the use of the XPert Filtered
Balance Station, which uses a remote blower.

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.

Consult a Labconco Technical Specialist for estimated saturation life. See Chapter
6 for an example of estimating saturation life. Another source is the Labconco
chemical guide for carbon-filtered enclosures.

Prohibited Acid Use

The XPert Filtered Balance System motorized impeller cannot be exposed to acids.
Where applications require the use of acids, a separate ventilated enclosure or
vented fume hood should be used with a remote blower ducted to the outside. No
exceptions are permitted, as the impeller life span will be limited with acid use.

LOW-LEVEL ACIDS CAN BE USED WITH THE XPERT
FILTERED BALANCE STATION, WHICH USES A REMOTE
BLOWER.
