| TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE | Not combustible. Gives
off irritating or toxic fumes (or gases) in a fire. |
NO water. In case of
fire in the surroundings: powder, carbon dioxide. | |
| EXPLOSION | In case of fire: cool
cylinder by spraying with water but avoid contact of the substance with
water. | ||
 | |||
| EXPOSURE | AVOID ALL CONTACT!
|
IN ALL CASES CONSULT
A DOCTOR! | |
| Inhalation | Sore throat. Cough.
Burning sensation. Shortness of breath. Laboured breathing. Symptoms may
be delayed (see Notes). |
Ventilation, local
exhaust, or breathing protection. |
Fresh air, rest.
Half-upright position. Artificial respiration if indicated. Refer for
medical attention. |
| Skin | Pain. Redness.
Blisters. Skin burns. ON CONTACT WITH LIQUID: FROSTBITE. |
Cold-insulating gloves.
Protective clothing. |
ON FROSTBITE: rinse
with plenty of water, do NOT remove clothes. Refer for medical attention.
|
| Eyes | Pain. Redness. Severe
deep burns. Loss of vision. |
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 take to a doctor. |

| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
| Evacuate danger area!
Consult an expert! Ventilation (extra personal protection: gas-tight
chemical protection suit including self-contained breathing apparatus).

|
| IMPORTANT DATA | |
| PHYSICAL STATE;
APPEARANCE: GAS OR COLOURLESS, FUMING LIQUID , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The gas is heavier than air. CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride. Reacts violently with water or moist air to form hydrogen chloride and boric acid. Reacts violently with aniline, phosphine, alcohols, oxygen and organic matter such as grease. Attacks many metals in presence of water. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
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 is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the gas may cause lung oedema (see Notes). Rapid evaporation of the liquid may cause frostbite. Exposure at high levels may result in death. The effects may be delayed. Medical observation is indicated. |
| PHYSICAL PROPERTIES | |
| Boiling point: 12.5°C
Melting point: -107°C Relative density (water = 1): 1.35 Solubility in water: reaction Vapour pressure, kPa at 20°C: 150 Relative vapour density (air = 1): 4.03 |
|
| ENVIRONMENTAL DATA | |
| NOTES | |
| Reacts
violently with fire extinguishing agents such as water. 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 spray, by
a doctor or a person authorized by him/her, should be considered.
