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.

4. First Aid Measures

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.

5. Fire Fighting Measures

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.

6. Accidental Release Measures

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.

7. Handling and Storage

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.

8. Exposure Controls/Personal Protection

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.
