Methane Not established-simple Not established-simple
asphyxiant asphyxiant
3. HAZARDS IDENTIFICATION / EMERGENCY OVERVIEW:
Methane is generally considered nontoxic. Exposures to concentrations of up to 9 percent methane
have been reported without apparent ill effects; inhalations of higher concentrations eventually causes
a feeling of pressure on the forehead and eyes, but the sensation ends after returning to fresh air.
Methane is a simple asphyxiant. Methane poses hazards to personnel through its flammability. All
precautions necessary for the safe handling of any flammable compressed gas must be observed in
working with methane. Very dangerous fire and explosion hazard when exposed to heat or flame.
Issue warning --- high flammability. Restrict access. Evacuate area. Reacts violently with powerful
oxidizers. Explosive in the form of vapor or gas when exposed to heat or flame. Flashback along
vapor trail may occur. May explode if ignited in an enclosed area. To fight fire, stop flow of gas.
POTENTIAL HEALTH EFFECTS:
EYE CONTACT: Vapors are nonirritating to the eyes
SKIN CONTACT: Practically harmless to the skin; but, because it evaporates quickly it may
cause frostbite.
INHALATION: Vapors are nonirritating to the throat. High concentrations may cause
asphyxiantion.

4. FIRST AID MEASURES
EYES: Not irritating to eyes, nose or throat.
SKIN: Liquid contact will cause frostbite. Flush affected areas with plenty of
water. Do Not Rub Affected Frostbitten Areas. Encourage victim to
exercise the affected part while it is being warmed.
INHALATION: Remove to fresh air. Support respiration. If breathing is difficult, give
oxygen.

HAZARDS: ignition or explosion exists if flame is extinguished without
stopping the flow of gas or cooling the surroundings. Burns
with a pale, faintly luminous flame; air containing more than
14% methane burns without noise.

PROCEDURES:
ignition and possible explosion a gas fire should not usually be
extinguished until surroundings have been cooled and the
supply of gas has been controlled and can be shut off.
6. ACCIDENTAL RELEASE MEASURES
SPILL OR LEAK Storage and use areas should be monitored for leakage of
PROCEDURES: methane, since methane (unless odorized) may not give
adequate warnings of its dangerous presence in the
atmosphere. It is lighter than air and presents hazards similar
to hydrogen with regard to its ignitiability. In the absence of
appropriate monitors, localized leaks may be difficult to detect
unless the gas is odorized. Therefore, periodic checks should
be made of connections and joints, flanges, and components
subject to leakage. Once a leak is found, shut-off the source of
gas and lower the pressure in the system to minimize the leak.
If uncontrolled leakage is encountered which cannot be stopped
by shutting off the closest appropriate valve or main supply
valve (without risk), implement a plan for evacuation and
quickly contact the local fire department.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION
RECOMMENDED WORK / HYGIENE Good ventilation will prevent formation of harmful
PROCEDURES: concentration in normal workplaces. Keep sparks,
flames, and other sources of ignition away.
Attempt to stop leak if can be done without undue
personnel hazard. Use water spray to knock down
vapors. If material is leaking but not yet on fire,
evacuate the downwind area immediately. Avoid
breathing the vapors. Keep upwind.
EYE PROTECTION REQUIREMENTS: Protect eyes from liquefied gas, may cause
frostbite type injury.
HAND PROTECTION Not normally required. Contact with liquefied gas
REQUIREMENTS: may cause frostbite type injury.
PROTECTIVE CLOTHING Use protective clothing if exposed to liquefied
REQUIREMENTS: natural gas.
RESPIRATORY REQUIREMENTS: Self-contained breathing apparatus for high
concentrations. Please note: If you have an
asphyxiant hazard, you have a bigger explosion
hazard.

Not harmful to aquatic life. The utilization of methane by some bacteria cultures, such as
Methylococcus and others, as a carbon source suggests that methane is biodegradeable.
13. DISPOSAL CONSIDERATIONS
Disposal of methane, as with other flammable gases, should be undertaken only by personnel
familiar with the gas and procedures for disposal. In general, the best procedure for disposal of
flammable gases, including methane, is to burn the gas using a flare system.
