IV FIRE AND EXPLOSION HAZARDS DATA

Fire: Not considered to be a fire hazard.
Explosion: Not considered to be a fire hazard.

Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire.
Special Information: Use protective clothing and breathing equipment appropriate for the surrounding fire.


V HEALTH HAZARD INFORMATION

Precautionary Measures: WARNING! Harmful If Swallowed or Inhaled. Affects Central Nervous System. May Cause Irritation
to Skin and Eyes. Avoid Breathing Dust. Keep Container Closed. Use with Adequate Ventilation. Avoid Contact with Eyes, Skin
and Clothing. Wash Thoroughly after Handling.

Exposure/Health Effects:

Inhalation: Dust may cause irritation to the respiratory tract; symptoms may include coughing, sore throat, and shortness of breath.
Ingestion: May cause nausea, vomiting and abdominal pain. Ingestions are usually promptly rejected by vomiting, but sufficient
absorption may occur to produce central nervous system effects. Symptoms may include drowsiness, irritability, dizziness, mania,
hallucinations, and coma.

Skin Contact: Dry material may cause mild irritation. Solutions may cause irritation, redness, pain, and skin burns.
Eye Contact: May cause irritation, redness, and pain.
Chronic Exposure: Repeated or prolonged inhalation or skin exposure may cause skin rashes (bromaderma). Repeated ingestion of
small amounts may cause central nervous system depression, including depression, ataxia, psychoses, memory loss, irritability, and
headache.

Aggravation of Pre-existing Medical Conditions: No information found
Toxicity (RTECS, 1986): No LD50/LC50 information found relating to normal routes of occupational exposure. Mutation refer-
ences cited.
EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove to fresh air. If not breathing, give artificial respiration, if difficult, give oxygen. Call a physician.
INGESTION: If swallowed, induce vomiting immediately by giving two glasses of water and sticking finger down throat. Never
give anything by mouth to an unconscious person. Call a physician immediately.
SKIN: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Call a physician immediately.
EYE: Wash eyes with plenty of water for at least 15 minutes, lifting upper eyelids occasionally. Get medical attention immediately.


VI REACTIVITY DATA

Stability: Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products: Emits toxic fumes of bromine when heated to decomposition.
Hazardous Polymerization: This does not polymerize.
Incompatibilities: Strong oxidizers, acids and bromine trifluoride.


VII SPILL OR LEAK PROCEDURES

Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal.
Ventilate area of leak or spill. Clean-up personnel may require respiratory protection from dust.

Disposal: Whatever cannot be saved for reclamation may be delivered to an approved waste disposal facility. Dispose of container
and unused contents in accordance with federal, state, and local requirements.

Storage and Special Information: Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect gainst physical
damage.


VIII SPECIAL PROTECTION INFORMATION

Airborne Exposure Limits: None Established
Ventilation System: A local exhaust system which captures the contaminant at its source is recommended to prevent dispersion of
the contaminant into the workroom air.

Personal Respirators: (NIOSH Approved) For conditions of use where exposure to the dust is apparent, a dust/mist respirator may
be worn. For emergencies or instances where the exposure levels are not known, use a positive-pressure, air-supplied respirator.
WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.

Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
