Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

Moderate concentration in air causes drowsiness, dizziness, and unconsciousness. Overexposure causes headache, drowsiness, muscular weakness. (USCG, 1999)

Excerpt from ERG Guide 115 [Gases - Flammable (Including Refrigerated Liquids)]: Vapors may cause dizziness or asphyxiation without warning. Some may be irritating if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases. (ERG, 2016)

SYMPTOMS: Acute exposure to this compound can produce irritation of eyes, nose, throat, mucous membranes and the upper respiratory tract. ACUTE/CHRONIC HAZARDS: This compound emits acrid fumes and smoke when heated to decomposition. It is an irritant of mucous membranes and the upper respiratory tract. (NTP, 1992)

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Aliphatic hydrocarbons and related compounds

To fight fire, stop flow of gas, use CO2, alcohol foam or dry chemical.

Special Hazards of Combustion Products: Vapors are anesthetic. Behavior in Fire: Container may explode. (USCG, 1999)

Excerpt from ERG Guide 115 [Gases - Flammable (Including Refrigerated Liquids)]: EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. CAUTION: Hydrogen (UN1049), Deuterium (UN1957), Hydrogen, refrigerated liquid (UN1966) and Methane (UN1971) are lighter than air and will rise. Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.) Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)

This chemical is combustible. (NTP, 1992)

Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.

Evacuate danger area! Ventilation. Remove all ignition sources. Turn off gas at source if possible. Personal protection: chemical protection suit including self-contained breathing apparatus.

Evacuate danger area! Ventilation. Remove all ignition sources. Turn off gas at source if possible. Personal protection: chemical protection suit including self-contained breathing apparatus.

Spills on land: Contain if possible, by forming mechanical and/or chemical barriers to prevent spreading.

NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Use non-sparking handtools. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Fireproof. Separated from strong oxidants.Store in cool dry, well-ventilated location. Protect against static electricity and lightning. Isolate from oxidizing materials, halogens, and other combustibles.

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.

Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).

Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

Use ventilation.

The substance may polymerize to form aromatic compounds under the influence of temperatures above 600°C. Reacts with strong oxidants. This generates fire and explosion hazard.

Decomposes on heating. This produces toxic and irritating fumes. This generates fire and explosion hazard. Reacts violently with fluorine. Reacts with strong acids and strong oxidants.

Flammable gasThe gas is lighter than air. As a result of flow, agitation, etc., electrostatic charges can be generated.,Dust explosion possible if in powder or granular form, mixed with air.Peroxidizable monomer may initiate exothermic polymerization of the bulk material [Bretherick 1979. p. 160]. Ethylene in the presence of aluminum chloride may undergo a violent reaction [J. Inst. Pet. 33:254. 1947]. Ozone and ethylene react explosively [Berichte 38:3837]. Ethylene can polymerize at low pressure if catalyzed by titanium halides. (Sundaram, K. M, M. M. Shreehan, E. F. Olszewski. "Ethylene." Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. 2001.)

On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.

Pure culture studies suggest that ethylene may be susceptible to microbial degradation(1-3).

An estimated BCF of 4 was calculated for ethylene(SRC), using a log Kow of 1.13(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

The Koc of ethylene is estimated as 98(SRC), using a log Kow of 1.13(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that ethylene is expected to have high mobility in soil.

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
