EMERGENCY OVERVIEW
Appearance: white to yellow solid.
Harmful if swallowed. Danger! Corrosive. Causes
eye and skin burns. May cause severe respiratory tract irritation
with possible burns. May cause severe digestive tract irritation
with possible burns.
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin burns. May be absorbed through the skin. May cause skin
rash (in milder cases), and cold and clammy skin with cyanosis or
pale color.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal tract burns. May cause
perforation of the digestive tract. May cause systemic effects.
Inhalation:
Causes chemical burns to the respiratory tract. Aspiration may lead
to pulmonary edema. May cause systemic effects.
Chronic:
Effects may be delayed. Laboratory experiments have resulted in
mutagenic effects. May cause adverse reproductive effects.
Section 4 - First Aid Measures
|
Eyes:
Get medical aid immediately. Do NOT allow victim to rub or keep eyes
closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do NOT 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 immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
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. Dusts at sufficient concentrations can form
explosive mixtures with air. During a fire, irritating and highly
toxic gases may be generated by thermal decomposition or combustion.
Contact with metals may evolve flammable hydrogen gas. Containers
may explode when heated. Runoff from fire control or dilution water
may cause pollution.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Do NOT get water
inside containers. For small fires, use dry chemical, carbon
dioxide, or water spray. For large fires, use dry chemical, carbon
dioxide, alcohol-resistant foam, or water spray.
Flash Point: 145 deg C ( 293.00 deg F)
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 3; Flammability: 1; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Do not breathe dust, vapor, mist, or
gas. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Do not ingest or inhale. Discard contaminated shoes.
Storage:
Store in a tightly closed container. Keep from contact with
oxidizing materials. Store in a cool, dry, well-ventilated area away
from incompatible substances.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
