Extinguishing Media:Use extinguishing agents appropriate for
surrounding fire.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Avoid inhalation of material or combustion
by-products. Stay upwind and keep out of low areas.
Unusual Fire/Explosion Hazard:Negligible fire hazard as long as the
container is not punctured or a wrong gas such as pure oxygen is
not accidentally piped to the canister.

Spill Release Procedures:Collect spilled material in appropriate
container for disposal.
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. See original container for
storage recommendations. Keep separated from incompatible
substances.
Other Precautions:

Respiratory Protection:Not required during normal system use. In the
event of system rupture, media removal from the system, or exposure
to the media: The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 30 ppm Any
supplied-air respirator. Any powered, air-purifying respirator with
acid gas cartridge(s). Any air-purifying respirator with a full
facepiece and an acid gas canister. Any self-contained breathing
apparatus with a full facepiece. Any supplied-air respirator with a
full facepiece. Escape - Any air-purifying respirator with a full
facepiece and an acid gas canister. Any appropriate escape-type,
self-contained breathing apparatus. For Unknown Concentrations or
Immediately Dangerous to Life or Health - Any supplied-air
respirator with full facepiece and operated in a pressure-demand or
other positive-pressure mode in combination with a separate escape
supply. Any self-contained breathing apparatus with a full
facepiece.
Ventilation:Not required during normal system use. In the event of
system rupture, media removal from the system, or exposure to the
media: Provide local exhaust ventilation system. Ensure compliance
with applicable exposure limits.
Protective Gloves:Not required during normal system use. In the event
of system rupture, media removal from the system, or exposure to
the media: Wear appropriate chemical resistant gloves.
Eye Protection:Not required during normal system use. In the event of
system rupture, media removal from the system, or exposure to the
media: Wear splash resistant safety goggles with a faceshield.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:Not required during normal system use. In
the event of system rupture, media removal from the system, or
exposure to the media: Wear appropriate chemical resistant
clothing.

Waste Disposal Methods:Dispose in accordance with all applicable
regulations. If the purification system is ever exposed to toxic
gases or gases containing toxic elements, the media may contain
these toxic materials, or reaction products thereof, and exhibit
the characteristic of toxicity as defined in the hazardous waste
regulations 40 CFR 261 Subpart C or D. System Recharge: The
customer may consult Matheson PBU for the disposal and recharge of
the system. Systems used to purify reactive or flammable gases must
be thoroughly purged with an inert gas prior to disposal.
