------------------------------------------------------------------------------
SECTION 5 FIRE FIGHTING MEASURES
------------------------------------------------------------------------------
FIRE AND EXPLOSION HAZARDS: Severe fire hazard. Severe explosion hazard.
Containers may rupture or explode if exposed to heat. Vapor/air mixtures are
explosive above flash point. Electrostatic discharges may be generated by
flow or agitation resulting in ignition or explosion.
EXTINGUISHING MEDIA: carbon dioxide, regular dry chemical
Large fires: Use regular foam or flood with fine water spray.
FIRE FIGHTING: Move container from fire area if it can be done without risk.
For fires in cargo or storage area: Cool containers with water from unmanned
hose holder or monitor nozzles until well after fire is out. If this is
impossible then take the following precautions: Keep unnecessary people
away, isolate hazard area and deny entry. Let the fire burn. Withdraw
immediately in case of rising sound from venting safety device or any
discoloration of tanks due to fire. For tank, rail car or tank truck: Stop
leak if possible without personal risk. Let burn unless leak can be stopped
immediately. For smaller tanks or cylinders, extinguish and isolate from
other flammables. Evacuation radius: 800 meters (1/2 mile). Stop flow of
gas.
FLASH POINT: -369 F (-223 C)
LOWER FLAMMABLE LIMIT: 5.0%
UPPER FLAMMABLE LIMIT: 15%
AUTOIGNITION: 999 F (537 C)
MGI14160 Page 003 of 007
------------------------------------------------------------------------------
SECTION 6 ACCIDENTAL RELEASE MEASURES
------------------------------------------------------------------------------
OCCUPATIONAL RELEASE:
Avoid heat, flames, sparks and other sources of ignition. Stop leak if
possible without personal risk. Reduce vapors with water spray. Keep
unnecessary people away, isolate hazard area and deny entry. Remove sources of
ignition. Ventilate closed spaces before entering.
------------------------------------------------------------------------------
SECTION 7 HANDLING AND STORAGE
------------------------------------------------------------------------------
STORAGE: Store and handle in accordance with all current regulations and
standards. Subject to storage regulations: U.S. OSHA 29 CFR 1910.106.
Grounding and bonding required. Keep separated from incompatible substances.
------------------------------------------------------------------------------
SECTION 8 EXPOSURE CONTROLS, PERSONAL PROTECTION
------------------------------------------------------------------------------
EXPOSURE LIMITS:
METHANE, COMPRESSED GAS:
No occupational exposure limits established.
VENTILATION: Based on available information, additional ventilation is not
required. Ensure compliance with applicable exposure limits.
EYE PROTECTION: Eye protection not required, but recommended.
CLOTHING: Protective clothing is not required.
GLOVES: Wear appropriate chemical resistant gloves.
RESPIRATOR: Under conditions of frequent use or heavy exposure, respiratory
protection may be needed. Respiratory protection is ranked in order from
minimum to maximum. Consider warning properties before use.
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.

SIMPLE ASPHYXIANTS: The symptoms of asphyxia depend on the rapidity with
which the oxygen deficiency develops and how long it continues. In sudden
acute asphyxia, unconsciousness may be immediate. With slow development
there may be rapid respiration and pulse, air hunger, dizziness, reduced
