**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns. May cause sensitization by skin contact.
Contact with combustible material may cause fire. May cause cancer
by inhalation. Very toxic to aquatic organisms, may cause long-term
adverse effects in the aquatic environment.Corrosive.
Potential Health Effects
Eye:
Causes severe eye burns. May cause permanent corneal
opacification. May cause chemical conjunctivitis and corneal damage.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. Causes severe burns with
delayed tissue destruction. May be harmful if absorbed through the
skin. Chrome ulcers, penetrating lesions of the skin, occur chiefly
on the hand and forearm where there has been a break in the
epidermis. 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. May
cause perforation of the digestive tract. May be harmful if
swallowed. May cause burns to the gastrointestinal tract. May cause
systemic effects. May cause nausea, vomiting, and diarrhea, possibly
with blood.
Inhalation:
Causes chemical burns to the respiratory tract. Vapor harmful.
Aspiration may lead to pulmonary edema. May cause systemic effects.
May cause acute pulmonary edema, asphyxia, chemical pneumonitis, and
upper airway obstruction caused by edema.
Chronic:
May cause liver and kidney damage. Effects may be delayed. Potential
cancer hazard.
**** 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. 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. Get medical aid immediately. Wash mouth out
with water.
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. Strong oxidizer. Contact with combustible materials
may cause a fire. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Use water with caution
and in flooding amounts. Vapors may be heavier than air. They can
spread along the ground and collect in low or confined areas. Some
oxidizers may react explosively with hydrocarbons(fuel). May
accelerate burning if involved in a fire. Containers may explode when
heated.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide. DO NOT USE 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. Provide ventilation. Do not use combustible
materials such as paper towels to clean up spill.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Keep container tightly closed. Avoid contact with clothing and other
combustible materials. Do not get on skin or in eyes. Do not ingest
or inhale. Use only in a chemical fume hood. Discard contaminated
shoes.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Store in a cool, dry place. Keep container
closed when not in use. Corrosives 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
ventilation to keep airborne concentrations low.
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 a chemical apron. Wear appropriate clothing to
prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Always use
a NIOSH or European Standard EN 149 approved
respirator when necessary.
