TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Extremely flammable.
|
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 water spray, alcohol resistant foam.
|
| EXPLOSION |
Gas/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
|
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.

| EXPOSURE |
|
STRICT HYGIENE!
|
IN ALL CASES CONSULT A DOCTOR!

|
Fresh air, rest. Refer for medical attention.
|
| Skin |
Redness. Pain.
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
|
| Eyes |
Redness. Pain.
|

| IMPORTANT DATA | |
|
PHYSICAL STATE; APPEARANCE:
COLOURLESS COMPRESSED GAS , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The gas is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance may spontaneously ignite on contact with air. The substance decomposes on heating above 350°C and on contact with oxidants, such as nitric acid. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.2 ppm; 0.63 mg/m 3 (as TWA) (ACGIH 1993-1994). |
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 irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the blood , resulting in lesions of blood cells. Exposure may result in death. |
| PHYSICAL PROPERTIES | |

| ENVIRONMENTAL DATA | |
|
|
| NOTES | |
|
Depending on the degree of exposure, periodic medical examination is indicated. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
