**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Reacts violently with water. Harmful by inhalation and if swallowed.
Contact with water liberates toxic gas. Causes severe
burns.Corrosive.Lachrymator (substance which increases the flow of
tears).Water-Reactive.
Potential Health Effects
Eye:
Causes eye burns. Causes redness and pain. Lachrymator (substance
which increases the flow of tears).
Skin:
Causes skin burns. May be absorbed through the skin in harmful
amounts. Causes redness and pain.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal tract burns.
Inhalation:
Harmful if inhaled. Causes chemical burns to the respiratory tract.
Inhalation may be fatal as a result of spasm, inflammation, edema of
the larynx and bronchi, chemical pneumonitis and pulmonary edema.
Chronic:
No information found.
**** 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
soap and 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 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:
**** 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. Water Reactive. Material will react with water and
may release a flammable and/or toxic gas. Containers may explode in
the heat of a fire. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas. Contact with
metals may evolve flammable hydrogen gas.
Extinguishing Media:
Do NOT use water directly on fire. If water is the only media
available, use in flooding amounts. Do NOT get water inside
containers. Cool containers with flooding quantities of water until
well after fire is out. For small fires, use dry chemical or carbon
dioxide.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Use a spark-proof tool. Do not get water inside
containers. Cover with dry earth, dry sand, or other non-combustible
material followed with plastic sheet to minimize spreading and
contact with water.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Keep container tightly closed. Do not get on skin or in eyes. Do not
ingest or inhale. Use with adequate ventilation. Do not allow contact
with water. Discard contaminated shoes.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from water. Corrosives area. Keep away from acids. Do not store in
metal containers.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower. Use only
under a chemical fume hood.
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear nitrile-latex gloves, apron, and/or clothing.
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear nitrile-latex gloves, apron, and/or clothing.
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.
