Potential 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, eye and brain effects. Symptoms may include skin
rash, blurred vision and other eye effects, 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 exposure by any route 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 Conditions: Persons suffering from
debilitation, depression, alcoholism, neurological or psychological disorders
may be more susceptible to the effects of this compound.
Inhalation: Remove to fresh air. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen. Call a
physician.
Ingestion: Induce vomiting immediately as directed by medical personnel.
Never give anything by mouth to an unconscious person. Call a physician.
Skin Contact: In case of contact, immediately flush skin with plenty of
water for at least 15 minutes. Call a physician.
Eye Contact: Immediately flush eyes with plenty of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Get medical attention
immediately.
Fire: Not considered to be a fire hazard.
Explosion: Not considered an explosion hazard, but reacts explosively
with bromine trifluoride.
Fire Extinguishing Media: Use any means suitable for extinguishing
surrounding fire. Water spray may be used to keep fire exposed containers cool.
Special Information: In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained breathing apparatus with full
facepiece operated in the pressure demand or other positive pressure mode.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from acids and alkalis. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits: None established.
Ventilation System: A system of local and/or general exhaust is
recommended to keep employee exposures as low as possible. Local exhaust
ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work
area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): For conditions of use where
exposure to dust or mist is apparent and engineering controls are not feasible,
a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil
particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a
NIOSH type R or P filter. For emergencies or instances where the exposure levels
are not known, use a full-face 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.
Appearance: Colorless crystals.
Odor: Odorless.

and storage. Slightly hygroscopic; slowly becomes yellowish in air.
Hazardous Decomposition Products: Emits toxic fumes of nitric oxides,
ammonia, hydrogen bromide, and bromine when heated to decomposition.
Hazardous Polymerization: Will not occur.
Incompatibilities: Bromine trifluoride, iodine heptafluoride, potassium,
and acid salts. Reacts with acids to form toxic hydrogen bromide and bases to
form ammonia.
Conditions to Avoid: Moisture and incompatibles.
