  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Gas/air mixtures are explosive.  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) if in liquid state. Use non-sparking handtools.  Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, carbon dioxide.  In case of fire: keep cylinder cool by spraying with water. 

 STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Lethargy. Headache. Abdominal cramps.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves. Protective clothing.  ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision.  Wear face shield or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.

1-CHLOROETHANE ICSC: 0132
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS COMPRESSED LIQUEFIED GAS WITH CHARACTERISTIC ODOUR. 

Physical dangers
The gas is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
Decomposes on heating and on burning. This produces toxic gases of hydrogen chloride (see ICSC 0163) and phosgene (see ICSC 0007). 

Formula: C2H5Cl / CH3CH2Cl
Molecular mass: 64.5
Boiling point: 12.5°C
Melting point: -138°C
Relative density (water = 1): 0.918
Solubility in water, g/100ml at 20°C: 0.574
Vapour pressure, kPa at 20°C: 133.3
Relative vapour density (air = 1): 2.22
Flash point: -50°C c.c.
Auto-ignition temperature: 519°C
Explosive limits, vol% in air: 3.6-14.8
Octanol/water partition coefficient as log Pow: 1.54  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation. 

Effects of short-term exposure
The substance is mildly irritating to the eyes, skin and respiratory tract. Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause unconsciousness, cardiac dysrhythmia and death. 

Inhalation risk
A harmful concentration of this gas in the air will be reached very quickly on loss of containment. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 100 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: skin absorption (H); carcinogen category: 3B.
EU-OEL: 268 mg/m3, 100 ppm as TWA 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
Use of alcoholic beverages enhances the harmful effect.
Rinse contaminated clothing with plenty of water because of fire hazard.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
