| 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. Unconsciousness.
|
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, nitrous oxide. OCCUPATIONAL EXPOSURE LIMITS: TLV: 25 ppm 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 , resulting in carboxyhaemoglobinemia and cardiac disorders. Exposure at high levels may result in 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.
