First Aid Measures

Ingestion

Induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.

Inhalation

Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

Skin

Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.

Eyes

Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Handling and Storage

Storage

Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from metals.

Handling

Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.

Hazards Identification

Ingestion

Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause liver and kidney damage.

Inhalation

Causes respiratory tract irritation. May cause liver and kidney damage. May cause lung damage. May cause headache, loss of appetite, nausea, fatigue, abdominal pain, darkened urine and jaundice..

Skin

May be absorbed through damaged or abraded skin in harmful amounts. Exposure may cause irritation and possible burns. Causes symptoms similar to those of inhalation.

Eyes

Contact with eyes may cause severe irritation, and possible eye burns.

Hazards

Containers may explode when heated.

Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.

Respirators

Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

Exposure limit(s)

OSHA PEL: TWA 1 ppm (14 mg/m3) NIOSH REL: See Appendix D NIOSH IDLH: 8 ppm

Fire Fighting Measures

Flash Point

97

Autoignition

335

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Runoff from fire control or dilution water may cause pollution. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.

Upper exp. limit

24.5

Fire Potential

May burn but does not ignite readily.

Accidental Release Measures

Small spills/leaks

Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Provide ventilation.

Stability and Reactivity

Stability

Stable under normal shipping and handling conditions.

Incompatibilities

Strong oxidizers, strong bases, and metals such as aluminum, magnesium, and zinc in the presence of steam. Will attack some forms of plastics, rubber,and coatings.

Decomposition

Irritating and toxic fumes and gases, hydrogen bromide, bromine fumes, carbonyl bromide.

Combustion Products

When heated, it emits highly toxic fumes of carbonyl bromide.
