|Hydrobromic acid||March 2001|
|CAS #: 10035-10-6|
| UN #: 1048 (anhydrous)
|EC Number: 233-113-0
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Not combustible. Heating will cause rise in pressure with risk of bursting. Risk of fire and explosion on contact with metals as a result of hydrogen formation.||In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water. NO direct contact with water.|
|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.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. Remove gas with fine water spray.||
According to UN GHS Criteria
|Separated from incompatible materials. See Chemical Dangers. Cool. Dry. Ventilation along the floor.|

Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 2 ppm as STEL.
MAK: 6.7 mg/m3, 2 ppm; peak limitation category: I(1); pregnancy risk group: D.
EU-OEL: 6.7 mg/m3, 2 ppm as STEL
|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 by an authorized person, should be considered.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT spray water on a leaking cylinder (to prevent corrosion of the 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.
