PROMPT MEDICAL ATTENTION AND REMOVAL FROM THE CONTAMINATED AREA IS
MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE EQUIPPED
WITH SELF-CONTAINED BREATHING APPARATUS.
If breathing is difficult, administer oxygen. If breathing has stopped, administer artificial respiration.

LEL(%): Not determined UEL(%): Not determined
Hazardous combustion products: None
Sensitivity to mechanical shock: None
Sensitivity to static discharge: None
FIRE AND EXPLOSION HAZARDS:
The majority of this product constitutes a nonflammable gas. Containers may rupture or explode from pressure
when exposed to heat or flames.
EXTINGUISHING MEDIA:
Any - Use media appropriate for surrounding fire.
FIRE FIGHTING INSTRUCTIONS:
Stop the flow of gas if it can be done without risk. Continue to cool surrounding containers until well after
flames are extinguished. Firefighters should wear a full-facepiece, NIOSH/MSHA-approved self-contained
breathing apparatus (SCBA) operated in positive pressure mode and full turnout gear.
If flame is extinguished and flow of gas continues, increase ventilation to prevent flammable mixture formation
in low areas or pockets.
6. Accidental Release Measures
Isolate hazard area, evacuate personnel and deny entry to unauthorized/unprotected individuals. Personnel
entering area should wear appropriate protective equipment including respiratory protection suitable for
unknown concentrations. Personnel should not re-enter hazard area until adequate oxygen is re-established. If
a leak is in user鈥檚 equipment, be certain to purge piping with an inert gas prior to attempting repairs. If leak is in
container of container valve, contact the appropriate emergency telephone number listed in Section 1 or call
your closest BOC location.
7. Handling and Storage
Electrical classification:
Nonhazardous.
Valve protection caps must remain in place unless container is secured with valve protection outlet piped to use
point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure
reducing regulator when connecting cylinder to lower pressure (< 3000 psig) piping or systems. Do not heat
cylinder by any means to increase the discharge rate of product from the cylinder. Use a check valve or trap in
the discharge line to prevent hazardous back flow into the cylinder.

PRODUCT NAME: METHANOL (聰 0.01%) IN AIR
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non-combustible construction
away from heavily trafficked areas and emergency exits. Do not allow the temperature where cylinders are
stored to exceed 125 掳F. Cylinders should be stored upright and firmly secured to prevent FALLING OR
BEING KNOCKED OVER. Use a 鈥渇irst in-first out鈥? inventory system to prevent full cylinders being stored for
excessive periods of time.
For additional recommendations, consult Compressed Gas Association Pamphlet P-1 and G-12.
Stationary customer site vessels should operate in accordance with the manufacturer's and BOC鈥檚 instruction. Do
not attempt to repair, adjust or in any other way modify the operation of these vessels. If there is a malfunction
or other type of operations problem with the vessel, contact the closest BOC location immediately.
Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.

12. Ecological Information
ENVIRONMENTAL FATE
Degradation of methanol in the atmosphere occurs via reaction with photochemically produced hydroxyl radicals
(approximate half-life of 17.8 days). Removal of methanol from air can occur via rainfall. Decomposition (via
biodegradation) of methanol in soil and water is expected to occur.
13. Disposal Considerations
Do not attempt to dispose of residual waste or unused quantities. Return in the shipping container PROPERLY
LABELED, WITH ANY VALVE OUTLET PLUGS OR CAPS SECURE AND VALVE PROTECTION CAP
IN PLACE to BOC Gases or authorized distributor for proper disposal.
Methanol is listed as a RCRA hazardous waste U154 (40 CFR 261.33).
