**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns. Harmful by inhalation.Corrosive.
Potential Health Effects
Eye:
May cause irreversible eye injury. Vapor or mist may cause
irritation and severe burns. Contact with liquid is corrosive to the
eyes and causes severe burns. May cause painful sensitization to
light.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. Contact with liquid is
corrosive and causes severe burns and ulceration.
Ingestion:
May cause circulatory system failure. Causes severe digestive tract
burns with abdominal pain, vomiting, and possible death. May cause
corrosion and permanent tissue destruction of the esophagus and
digestive tract.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema. Causes
chemical burns to the respiratory tract. Exposure to the mist and
vapor may erode exposed teeth. Causes corrosive action on the mucous
membranes.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Repeated
exposure may cause erosion of teeth. May cause fetal effects.
Laboratory experiments have resulted in mutagenic effects. Prolonged
exposure may cause conjunctivitis, photosensitization, and possible
blindness.
**** 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). SPEEDY ACTION IS CRITICAL!
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. Give milk of
magnesia.
Inhalation:
Get medical aid immediately. Remove from exposure to fresh air
immediately. If not breathing, give artificial respiration. 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:
Do NOT use sodium bicarbonate in an attempt to neutralize the acid.
Antidote:
Do NOT use oils or ointments in eye.
**** 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 runoff can cause environmental damage. Dike
and collect water used to fight fire. During a fire, irritating and
highly toxic gases may be generated by thermal decomposition or
combustion. Not flammable, but reacts with most metals to form
flammable hydrogen 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. Reaction with
water may generate much heat which will increase the concentration
of fumes in the air. Containers may explode when heated.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Substance is nonflammable; use agent most
appropriate to extinguish surrounding fire. Do NOT get water inside
containers. Do NOT use straight streams of water. Most foams will
react with the material and release corrosive/toxic gases. 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:
Large spills may be neutralized with dilute alkaline solutions of
soda ash, or lime. Avoid runoff into storm sewers and ditches which
lead to waterways. Clean up spills immediately, observing
precautions in the Protective Equipment section. Provide
ventilation. A vapor suppressing foam may be used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Remove contaminated clothing and wash before reuse. Contents may
develop pressure upon prolonged storage. 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 cool, dry place. Do not store in direct sunlight. 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. Corrosives area. Do not store in metal
containers.
**** 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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
Personal Protective Equipment
Eyes:
Wear chemical goggles.
Skin:
Wear appropriate protective gloves to prevent skin
exposure. Wear neoprene or polyvinyl chloride gloves
to prevent 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.
