============= Composition/Information on Ingredients =============
Name:METHANE
CAS:74-82-8
Fraction by Wt: 100.0%
===================== Hazards Identification =====================
Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
nausea, vomiting, dizziness, tingling sensation, suffocation,
convulsions, coma LONG TERM EXPOSURE: no information on significant
adverse effects SKIN CONTACT: SHORT TERM EXPOSURE: no information
is available LONG TERM EXPOSURE: no information is available EYE
CONTACT: SHORT TERM EXPOSURE: no information is available LONG TERM
EXPOSURE: no information is available INGESTION: SHORT TERM
EXPOSURE: ingestion of a gas is unlikely LONG TERM EXPOSURE: no
information is available
Medical Cond Aggravated by Exposure:
======================= First Aid Measures =======================
First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
If breathing is difficult, oxygen should be administered by
qualified personnel. Get immediate medical attention. SKIN CONTACT:
Wash exposed skin with soap and water. EYE CONTACT: Flush eyes with
plenty of water. INGESTION: If a large amount is swallowed, get
medical attention. NOTE TO PHYSICIAN: For inhalation, consider
oxygen.
===================== Fire Fighting Measures =====================
Flash Point:-369 F (-223 C)
Autoignition Temp:999 F (537 C)
Lower Limits:5.0%
Upper Limits:15%
Extinguishing Media:carbon dioxide, regular dry chemical Large fires:
Use regular foam or flood with fine water spray.
Fire Fighting Procedures: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.
Unusual Fire/Explosion Hazard:Severe fire hazard. Severe explosion
hazard. Pressurized containers may rupture or explode if exposed to
sufficient heat. Vapor/air mixtures are explosive above flash
point. Electrostatic discharges may be generated by flow or
agitation resulting in ignition or explosion.
================== Accidental Release Measures ==================
Spill Release Procedures: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.
Neutralizing Agent:
====================== Handling and Storage ======================
Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Grounding and bonding
required. Subject to storage regulations: U.S. OSHA 29 CFR
1910.101. Keep separated from incompatible substances.
Other Precautions:
============= Exposure Controls/Personal Protection =============
Respiratory Protection: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. Any self-contained breathing apparatus with a full
facepiece.
Ventilation:Ventilation equipment should be explosion-resistant if
explosive concentrations of material are present. Provide local
exhaust ventilation system. Ensure compliance with applicable
exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Eye protection not required, but recommended.
Other Protective Equipment:Protective clothing is not required.
