WARNING
.
TOXIC AND OXIDIZING GAS
This module generates ozone which is toxic by inhalation and is a strong irritant to throat and
lungs. Ozone is also a strong oxidizing agent. Its presence is detected by a characteristic pungent
odor.
The module's exhaust contains both ozone and nitrogen dioxide, both toxic by inhalation, and may
contain other constituents of the sample gas which may be toxic. Such gases include various ox-
ides of nitrogen, unburned hydrocarbons, carbon monoxide and other products of combustion re-
actions. Carbon monoxide is highly toxic and can cause headache, nausea, loss of consciousness,
and death.
Avoid inhalation of the ozone produced within the module, and avoid inhalation of the sample and
exhaust products transported within the module. Avoid inhalation of the combined exhaust prod-
ucts at the exhaust fitting.
Keep all tube fittings tight to avoid leaks The user is responsible for testing for leakage only at the
inlet and outlet fittings on the rear panel. Periodically, the user should do an internal leak test (with
a test procedure chosen by the user).
Connect rear exhaust outlet to outside vent with stainless steel or Teflon line. Check vent line and
connections for leakage.
