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

EMERGENCY OVERVIEW
Causes burns.Moisture sensitive.Corrosive.

Potential Health Effects
Eye:
Causes eye burns. Lachrymator (substance which increases the flow
of tears).
Skin:
Causes skin burns.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract. Causes irritation of
mucous membrane. Causes corrosive action on the mucous membranes.
Chronic:
No information found. Chronic inhalation may cause spasm,
inflammation and edema of the larynx and bronchi, chemical
pneumonitis, and pulmonary edema.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
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.

such as a bag and a mask.
Notes to Physician:
Antidote:
None reported.

**** 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Do NOT get water
inside containers. Use water spray, dry chemical, carbon dioxide, or
appropriate foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.

inhale. Use with adequate ventilation. Do not allow contact with
water. Discard contaminated shoes. Keep from contact with moist air
and steam.
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. Corrosives area. Store protected from
moisture.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
