TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Extremely flammable. Heating will cause rise in pressure with risk of bursting.  NO open flames, NO sparks and NO smoking.  Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with carbon dioxide, water spray, powder. 
EXPLOSION Gas/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.  In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 
 
EXPOSURE   AVOID EXPOSURE OF (PREGNANT) WOMEN!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Headache. Confusion. Dizziness. Nausea. Weakness. Unconciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. See Notes.

IMPORTANT DATA
Physical State; Appearance
ODOURLESS TASTELESS COLOURLESS COMPRESSED GAS. 

Physical dangers
The gas mixes well with air, explosive mixtures are easily formed. The gas penetrates easily through walls and ceilings. 

Chemical dangers
May react vigorously with oxygen, acetylene, chlorine, fluorine or nitrous oxide. 

Occupational exposure limits
TLV: 25ppm as TWA; BEI issued; (ACGIH 2006).
MAK: 30 ppm, 35 mg/m³; Peak limitation category: II(1); Pregnancy risk group: B; BAT issued; (DFG 2008). 

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

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

Effects of short-term exposure
The substance may cause effects on the blood. This may result in carboxyhaemoglobinemia and cardiac disorders. Exposure at high levels could cause death. Medical observation is indicated. 

Effects of long-term or repeated exposure
The substance may have effects on the cardiovascular system and central nervous system. May cause toxicity to human reproduction or development.

NOTES
Carbon monoxide is a product of incomplete combustion of coal, oil, wood.
It is present in vehicle exhaust and tobacco smoke.
Depending on the degree of exposure, periodic medical examination is suggested.
No odour warning if toxic concentrations are present.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Card has been partially updated in November 2008: see Occupational Exposure Limits.
