Extinguishing Media:regular dry chemical, dry sand, lime, soda ash
Fire Fighting Procedures:Do not use water. Do not use foam. Move
container from fire area if it can be done without risk. Avoid
inhalation of material or combustion by-products.
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:Avoid heat, flames, sparks and other sources
of ignition. Do not touch spilled material. Stop leak if possible
without personal risk. Do not get water directly on material. Small
spills: Collect material into suitable, loosely covered container
for disposal. Keep unnecessary people away, isolate hazard area and
deny entry. Stay upwind and keep out of low areas. Notify Local
Emergency Planning Committee and State Emergency Response
Commission for release greater than or equal to RQ (U.S. SARA
Section 304). If release occurs in the U.S. and is reportable under
CERCLA Section 103, notify the National Response Center at
(800)424-8802 (USA) or (202)426-2675 (USA).
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Store at ambient
temperatures with contents under dry inert gas pressure at 5-15
psig. Notify State Emergency Response Commission for storage or use
at amounts greater than or equal to the TPQ (U.S. EPA SARA Section
302). SARA Section 303 requires facilities storing a material with
a TPQ to participate in local emergency response planning (U.S. EPA
40 CFR 355.30). 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. 50 ppm Any
chemical cartridge respirator with cartridge(s) providing
protection against this substance. Any air-purifying respirator
with a full facepiece and a canister providing protection against
this substance. Any powered, air-purifying respirator with
cartridge(s) providing protection against this substance. Any
supplied-air respirator. Any self-contained breathing apparatus
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.

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.
