EMERGENCY OVERVIEW
Appearance: white crystalline powder.
Warning! Causes eye irritation. Possible risk of
harm to the unborn child. May cause central nervous system effects.
Hygroscopic (absorbs moisture from the air).
Target Organs: Central nervous system, eyes.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
May cause skin irritation. Exposure to bromides may cause rashes,
especially of the face (resembling acne) and boils.
Ingestion:
May cause central nervous system depression, characterized by
excitement, followed by headache, dizziness, drowsiness, and nausea.
Advanced stages may cause collapse, unconsciousness, coma and
possible death due to respiratory failure.
Inhalation:
Inhalation of bromides may cause irritation of the upper respiratory
tract and lung tissue.
Chronic:
Chronic ingestion may cause bromism characterized by disturbances of
the central nervous system, skin and digestive tract. Repeated oral
intake of bromides (>9 mg/kg/day) may affect the central nervous
system. Warning symptoms include mental dullness, slurred speech,
weakened memory, apathy, anorexia, constipation, drowsiness and loss
of sensitivity to touch and pain.
Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Substance is noncombustible.

Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Avoid breathing dust.
Storage:
Store in a cool, dry place. Store protected from moisture.
Section 8 - Exposure Controls, Personal Protection
|
