**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Reacts violently with water. Toxic if swallowed. Causes
burns.Corrosive.Water-reactive.Air sensitive.
Potential Health Effects
Eye:
Causes severe eye burns. May result in corneal injury.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration.
Ingestion:
May be fatal if swallowed. May cause irritation of the digestive
tract and possible burns.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema. May
cause burns to the respiratory tract.
Chronic:
No information found.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and 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:
**** 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. Vapors can travel to a source of ignition and flash
back. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Water Reactive.
Material will react with water and may release a flammable and/or
toxic gas. Use water spray to keep fire-exposed containers cool.
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. Vapors may form an explosive mixture with
air. Containers may explode when heated or if contaminated with
water. Substance will react with water (some violently) releasing
flammable, toxic, or corrosive gases and runoff.
Extinguishing Media:
Do NOT use water directly on fire. Use water spray to cool
fire-exposed containers. Use carbon dioxide or dry chemical. Do NOT
get water inside containers. Do NOT use straight streams of water.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Neutralize spill with sodium
bicarbonate. Use water spray to disperse the gas/vapor. Remove all
sources of ignition. Provide ventilation. Do not get water on
spilled substances or inside containers.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Do not allow water
to get into the container because of violent reaction. Do not get in
eyes, on skin, or on clothing. Keep container tightly closed. Do not
ingest or inhale.
Storage:
Keep container closed when not in use. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from water.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 506-96-7:
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 appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
