First Aid Measures

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.

Handling and Storage

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.

Hazards Identification

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.

Ingestion

Nausea and vomiting occur following acute or chronic ingestion. Anorexia and weight loss may occur with chronic intoxication.

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.

Exposure Controls/Personal Protection

Personal 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.

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.
