TYPES OF HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE | Not combustible. Heating will cause rise in pressure with risk of bursting. | In case of fire in the surroundings, use appropriate extinguishing media. | |
| EXPLOSION | Risk of fire and explosion on contact with metals as a result of hydrogen formation. | In case of fire: keep cylinder cool by spraying with water. NO direct contact with water. | |
| EXPOSURE | AVOID ALL CONTACT! | IN ALL CASES CONSULT A DOCTOR! | |
| Inhalation | Burning sensation. Cough. Sore throat. Laboured breathing. Shortness of breath. Symptoms may be delayed. See Notes. | Use ventilation, local exhaust or breathing protection. | Fresh air, rest. Half-upright position. Refer for medical attention. |
| Skin | ON CONTACT WITH LIQUID: FROSTBITE. Redness. Pain. Blisters. | Cold-insulating gloves. Protective clothing. | ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention . |
| Eyes | Redness. Pain. Severe deep burns. | Wear eye protection in combination with breathing protection. | First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. |
| Ingestion | Do not eat, drink, or smoke during work. | ||

| NOTES |
|
The occupational exposure limit value should not be exceeded during any part of the working exposure. 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 inhalation therapy by a doctor or a person authorized by him/her, should be considered. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder). Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. Other UN number: 1788 Hydrobromic acid (solution), hazard class 8. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response. Card has been partially updated in July 2007: see Occupational Exposure Limits. |
