**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Harmful by inhalation and if swallowed. Causes
burns.Corrosive.Moisture sensitive.
Potential Health Effects
Eye:
Eye damage may be delayed. Contact with liquid is corrosive to the
eyes and causes severe burns. When substance becomes wet or comes in
contact with moisture of the mucous membranes, it will cause
irritation. May cause chemical conjunctivitis and corneal damage.
Skin:
Contact with skin causes irritation and possible burns, especially
if the skin is wet or moist. Prolonged skin contact may be painless
with reddening of the skin followed be a white appearance of the
skin. Skin burns may be delayed. May cause cyanosis of the
extremities. May cause skin rash (in milder cases), and cold and
clammy skin with cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. May be harmful if swallowed. Ingestion of large amounts may
cause CNS depression. May cause systemic effects.
Inhalation:
Harmful if inhaled. Causes severe irritation of upper respiratory
tract with coughing, burns, breathing difficulty, and possible coma.
Causes chemical burns to the respiratory tract. May cause lung
damage. Aspiration may lead to pulmonary edema. Vapors may cause
dizziness or suffocation. May cause systemic effects. May cause
burning sensation in the chest.
Chronic:
Effects may be delayed.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse. Discard contaminated clothing in a manner
which limits further exposure. If water-reactive products are
embedded in the skin, no water should be applied. The embedded
products should be covered with a light oil.
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 may form an explosive mixture with air.
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. Wear appropriate protective
clothing to prevent contact with skin and eyes. Wear a self-contained
breathing apparatus (SCBA) to prevent contact with thermal
decomposition products. Containers may explode in the heat of a
fire. Flammable liquid and vapor. May ignite or explode on contact
with steam or moist air.
Extinguishing Media:
Use dry sand or earth to smother fire. If water is the only media
available, use in flooding amounts. DO NOT USE WATER! Do NOT use
straight streams of water. Contact professional fire-fighters
immediately. Cool containers with flooding quantities of water until
well after fire is out.
**** 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. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. Do
not expose spill to water. Spill may be carefully neutralized with
lime (calcium oxide, CaO). Cover with material such as dry soda ash
or calcium carbonate and place into a closed container for disposal.
A vapor suppressing foam may be used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Remove contaminated clothing and wash before reuse. Do not allow
water to get into the container because of violent reaction. Ground
and bond containers when transferring material. Use spark-proof tools
and explosion proof equipment. Do not breathe dust, vapor, mist, or
gas. Do not get in eyes, on skin, or on clothing. Empty containers
retain product residue, (liquid and/or vapor), and can be dangerous.
Keep away from heat, sparks and flame. Use with adequate ventilation.
Discard contaminated shoes. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames. Keep from contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Do not store in direct sunlight. Keep container closed
when not in use. Keep from contact with oxidizing materials. Store in
a cool, dry, well-ventilated area away from incompatible substances.
Keep away from water. Flammables-area.
**** 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 general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
Personal Protective Equipment
Eyes:
Wear chemical goggles.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
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.
