| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE | Not
combustible but forms flammable gas on heating. Gives off irritating or
toxic fumes (or gases) in a fire. |
In case of
fire in the surroundings: all extinguishing agents allowed.
| |
| EXPLOSION |
| EXPOSURE | AVOID ALL
CONTACT! |
IN ALL
CASES CONSULT A DOCTOR! | |
| Inhalation | Sore throat.
Cough. Burning sensation. Convulsions. Dizziness. Headache. Shortness of
breath. Laboured breathing. Nausea. Unconsciousness. Vomiting.
|
Closed
system and ventilation. |
Fresh air,
rest. Half-upright position. Artificial respiration if indicated. Refer
for medical attention. |
| Skin | MAY BE
ABSORBED! Redness. Pain. Blisters (further see Inhalation). |
Protective
gloves. Protective clothing. |
Remove
contaminated clothes. Rinse skin with plenty of water or shower. Refer for
medical attention. |
| Eyes | Redness.
Pain. |
Safety
goggles, 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. |
| Ingestion | Abdominal
pain. (Further see Inhalation). |
Do not eat,
drink, or smoke during work. Wash hands before eating. |
Refer for
medical attention. See Notes. Rinse mouth. Induce vomiting (ONLY IN
CONSCIOUS PERSONS!). |

| IMPORTANT DATA | |||
| PHYSICAL
STATE; APPEARANCE: COLOURLESS OR WHITE CRYSTALS, WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air. CHEMICAL DANGERS: The substance decomposes on heating and on contact with acids producing highly toxic and flammable hydrogen cyanide (see ICSC # 0492) and corrosive hydrogen bromide (see ICSC # 0282). Reacts with strong oxidants. Reacts slowly with water and moisture to produce hydrogen bromide and hydrogen cyanide. 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 of its vapour, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes, the skin and the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes). The effects may be delayed. The substance may cause effects on the cellular respiration, resulting in convulsions, unconsciousness and respiratory failure. Medical observation is indicated. Exposure may result in death. | ||

| ENVIRONMENTAL DATA | |||
| It is strongly advised not to let the chemical enter into the
environment. | |||
| NOTES | |||
| Specific treatment is necessary in case of poisoning with this
substance; the appropriate means with instructions must be available.
Sublimes at room temperature. 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 are therefore essential.
Immediate administration of an appropriate spray, by a doctor or a person
authorized by him/her, should be considered. Commercial products are
generally solutions in chloroform. Environmental effects from the
substance have not been investigated. | |||
