**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Causes burns.Corrosive.

Potential Health Effects
Eye:
Causes eye burns. May result in corneal injury. May cause
blindness.
Skin:
Causes skin burns.
Ingestion:
Aspiration hazard. Causes gastrointestinal tract burns. May cause
kidney damage. Causes cough, sore throat, chest pain, and
lightheadedness.
Inhalation:
Causes chemical burns to the respiratory tract. May cause
bronchopneumonia and possible death.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Prolonged
or repeated exposure may cause adverse reproductive effects.

**** 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.
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. 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 not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
Evacuate area and fight fire from a safe distance. As in any fire,
wear a self-contained breathing apparatus in pressure-demand,
MSHA/NIOSH (approved or equivalent), and full protective gear. Use
water spray to keep fire-exposed containers cool. Oxidizer. Greatly
increases the burning rate of combustible materials. Containers may
explode in the heat of a fire. Contact with metals may evolve
flammable hydrogen gas.
Extinguishing Media:
Do NOT get water inside containers. For large fires, use dry
chemical, carbon dioxide, alcohol-resistant foam, or water spray. For
small fires, use dry chemical, carbon dioxide, water spray or regular
foam. 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:
Reduce airborne dust and prevent scattering by moistening with
water. Wear a self contained breathing apparatus and appropriate
personal protection. (See Exposure Controls, Personal Protection
section). Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Remove all sources of
ignition. Provide ventilation. Do not get water inside containers.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Keep container tightly closed. Do not
get on skin or in eyes. Do not ingest or inhale.
Storage:
Do not store near combustible materials. 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:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
