3. HAZARDS IDENTIFICATION
NFPA RATINGS (SCALE 0-4): HEALTH=1 FIRE=4 REACTIVITY=0
EMERGENCY OVERVIEW:
COLOR: colorless
PHYSICAL FORM: gas
ODOR: odorless
MAJOR HEALTH HAZARDS: difficulty breathing
PHYSICAL HAZARDS: Flammable gas. May cause flash fire. Electrostatic charges
may be generated by flow, agitation, etc.
POTENTIAL HEALTH EFFECTS:
INHALATION:
SHORT TERM EXPOSURE: nausea, vomiting, difficulty breathing, irregular heartbeat,
headache, drowsiness, fatigue, dizziness, disorientation,
mood swings, tingling sensation, loss of coordination,
suffocation, convulsions, unconsciousness, coma
LONG TERM EXPOSURE: no information is available
SKIN CONTACT:
SHORT TERM EXPOSURE: no information on significant adverse effects
LONG TERM EXPOSURE: no information is available
EYE CONTACT:
SHORT TERM EXPOSURE: no information on significant adverse effects
LONG TERM EXPOSURE: no information is available
INGESTION:
SHORT TERM EXPOSURE: ingestion of a gas is unlikely
LONG TERM EXPOSURE: no information is available
4. FIRST AID MEASURES
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.
5. FIRE FIGHTING MEASURES
FIRE AND EXPLOSION HAZARDS: 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.
EXTINGUISHING MEDIA: carbon dioxide, regular dry chemical
Large fires: Use regular foam or flood with fine water spray.
Page 2 of 6
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)
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.
7. HANDLING AND STORAGE
STORAGE: 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.
8. EXPOSURE CONTROLS, PERSONAL PROTECTION
EXPOSURE LIMITS:
METHANE, COMPRESSED GAS:
ALIPHATIC HYDROCARBON GASES ALKANE (C1-C4): 1000 ppm ACGIH TWA
METHANE: No occupational exposure limits established.
ALIPHATIC HYDROCARBON GASES ALKANE (C1-C4): 1000 ppm ACGIH TWA
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.
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 -
