Synonym:
  Synonyms * Acetene * Athylen (German) * Bicarburretted hydrogen * Elayl * Ethene * Ethylene (ACGIH:OSHA) * Liquid ethyene * Olefiant gas
CAS Number : 74-85-1
HAZARD (GHS)
EXPOSURE CONTROLS/PERSONAL PROTECTION
Extreamly flammable gas / May cause respiratory irritation; or may cause drowsiness or dizziness / harmful to aquatic life / harmful to aquatic life with long lasting effects
ENGINEERING CONTROLS
     Mechanical exhaust required.  Safety shower and eye bath.
     Warning:  suck-back into cylinder may cause rupture.  Use back-flow-preventive device in piping.
GENERAL HYGIENE MEASURES
     Wash contaminated clothing before reuse.  Wash thoroughly after handling.
PERSONAL PROTECTIVE EQUIPMENT
     Respiratory Protection:  Government approved respirator in nonventilated areas and/or for exposure above the TLV or PEL.
     Hand Protection:  Compatible chemical-resistant gloves.
     Eye Protection:  Chemical safety goggles.
WORK PRACTICES
     Store and use with adequate ventilation.
HANDLING
     Directions for Safe Handling:  Do not breathe gas.  Do not get in eyes, on skin, on clothing.  Avoid prolonged or repeated exposure.
STORAGE
     Conditions of Storage:  Keep tightly closed.  Keep away from heat, sparks, and open flame.  Cylinder temperature should not exceed 125?F (52?C).
     Incompatible Materials:  Mixtures of ethylene and aluminum chloride at 30-60 bar pressure will rapidly heat and explode in the presence of supported nickel catalysts, methyl chloride or nitromethane.  The mixing of ethylene with trifluoromethyl hypofluorite in the absence of a diluent results in an explosion.  Reaction with chlorine, ozone or nitrogen oxide is explosive.  When ethylene is passed over heated lithium incandescence occurs and produces a mixture of lithium hydride and lithium acetylide.  When 5A molecular sieves were used to dry a compressed ethylene gas stream, an exothermic reaction took place and caused an explosion.  Smaller 3A molecular sieves are not catalytically active toward ethylene
SPECIAL REQUIREMENTS:
     Contents under pressure.

FIRE FIGHTING MEASURES

FIRST-AID MEASURES

PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
     Evacuate area and keep personnel upwind.  Shut off all sources of ignition.  Shut off leak if there is no risk.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
     Wear self-contained breathing apparatus, rubber boots, and heavy rubber gloves.
METHODS FOR CLEANING UP
     Ventilate area and wash spill site after material pickup is complete.
EXTINGUISHING MEDIA
     Suitable:  Use water spray or fog nozzle to keep cylinder cool.  Move cylinder away from fire if there is no risk.
SPECIAL RISKS
     Specific Hazard(s):  Extremely flammable.  Vapor may travel considerable distance to source of ignition and flash back.  Emits toxic fumes under fire conditions.
     Explosion Hazards:  May form explosive mixtures with air Vapor may travel considerable distance to source of ignition and flash back.  Container explosion may occur under fire conditions.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
     Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
SPECIFIC METHOD(S) OF FIRE FIGHTING
     Do not extinguish burning gas if flow cannot be shut off immediately.  Use water spray or fog nozzle to keep cylinder cool.  Move cylinder away from fire if there is no risk.
AFTER INHALATION
     If inhaled, remove to fresh air.  If not breathing give artificial respiration.  If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
     In case of contact, immediately wash skin with soap and copious amounts of water.
AFTER EYE CONTACT
     Contamination of the eyes should be treated by immediate and prolonged irrigation with copious amounts of water.  Assure adequate flushing of the eyes by separating the eyelids with fingers.
AFTER INGESTION
     If swallowed, wash out mouth with water provided person is conscious.  Call a physician.
