ETHYL IODIDEICSC: 0479 (April 2004)
Iodoethane
Ethane iodide
Monoiodoethane
CAS #: 75-03-6
EC Number: 200-833-1

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 61°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 61°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, powder, foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Confusion. Cough. Drowsiness. Dizziness. Shortness of breath. Sore throat. Unconsciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles, 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 Abdominal pain. Confusion. Dizziness. Drowsiness. Unconsciousness.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. TURNS DARK ON EXPOSURE TO LIGHT. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on burning. This produces iodine and hydrogen iodide. Reacts with strong bases and strong oxidants.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in lowering of consciousness. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.01 ppm as TWA; A4 (not classifiable as a human carcinogen).
MAK skin absorption (H) 

ENVIRONMENT
 

NOTES
Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
