Hazards and Protection.
Storage
Refrigerator/flammables.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate clothing to prevent any reasonable probability of skin contact. Wear eye protection to prevent any possibility of eye contact.
Respirators
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.
Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container.
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents - peroxides - copper, copper alloys - plastics.
Decomposition
Carbon monoxide, carbon dioxide, hydrogen bromide.

Fire fighting
Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Use alcohol foam, dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
EXTREMELY FLAMMABLE.
Hazards
May polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Containers may explode when heated. Ruptured cylinders may rocket.
Combustion products
Fire may produce irritating and/or toxic gases.

Exposure effects
Fever may occur with chronic intoxication. Acute intoxication can result in CNS depression and coma. Bromides cross the placenta and may be detected in the milk of nursing mothers. Case reports suggest that prenatal exposure may cause growth retardation, craniofacial abnormalities and developmental delay.
   Ingestion
Nausea and vomiting occur following acute or chronic ingestion. Anorexia and weight loss may occur with chronic intoxication.
   Inhalation
Various pulmonary abnormalities have occurred including dyspnea, asthma and pneumonoconiosis.
   Skin
Bromide toxicity is associated in about 25% of cases with the development of bromoderma, an erythematous, nodular or acneiform rash over the face and possibly the entire body. One case of toxic epidermal necrolysis has been reported.
   Eyes
Pupils may be normal, miotic or mydriatic. Nystagmus is common.

First aid
 
   Ingestion
Do NOT induce vomiting. Allow the victim to rinse his mouth and then to drink 2-4 cupfuls of water, and seek medical advice.
   Inhalation
Remove from exposure to fresh air immediately.
   Skin
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
