| 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 powder, carbon dioxide.
|
| 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.
|
| EXPOSURE |
|
AVOID ALL CONTACT!
|
IN ALL CASES CONSULT A DOCTOR!
|
| Inhalation |
Burning sensation. Cough. Headache. Nausea. Shortness of breath.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
|
| Skin |
|
Cold-insulating gloves.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
|
| Eyes |
Causes watering of the eyes. Redness. Pain. Blurred vision.
|
Safety goggles, or eye protection in combination with breathing protection.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
|
Do not eat, drink, or smoke during work.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: GAS, WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The gas mixes well with air, explosive mixtures are formed easily. CHEMICAL DANGERS: The substance polymerizes due to warming. Reacts with oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.3 ppm (Ceiling value); A2; SEN; (ACGIH 2004). MAK: 0.3 ppm, 0.37 mg/m³; Sh; Peak limitation category: I(2); Carcinogen category: 4; Germ cell mutagen group: 5; Pregnancy risk group: C; (DFG 2004). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: On loss of containment, a harmful concentration of this gas in the air will be reached very quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes and is irritating to the respiratory tract. Inhalation of may cause lung oedema (see Notes). EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: This substance is carcinogenic to humans. | ||
| PHYSICAL PROPERTIES | |||
|
Boiling point: -20°C Melting point: -92°C Relative density (water = 1): 0.8 Solubility in water: very good Relative vapour density (air = 1): 1.08 |
Flash point: Flammable Gas Auto-ignition temperature: 430°C Explosive limits, vol% in air: 7-73 | ||
| ENVIRONMENTAL DATA | |||
|
| |||
| NOTES | |||
|
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. The occupational exposure limit value should not be exceeded during any part of the working exposure.
