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

EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes and skin.Light
sensitive.Moisture sensitive.

Potential Health Effects
Eye:
Causes severe eye irritation. May result in corneal injury.
Skin:
Contact with skin causes irritation and possible burns, especially
if the skin is wet or moist. If absorbed, may cause symptoms similar
to those for ingestion. May cause skin rash and eruptions.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause "salicylism"; characterized by headache,
dizziness, ringing in the ears, hearing difficulty, visual
disturbances, mental confusion, drowsiness, sweating thirst,
hyperventilation, nausea, vomiting and diarrhea. May be harmful if
swallowed. Severe salicylate intoxication may cause central nervous
system disturbances such as convulsions and coma, skin eruptions, and
alteration in the acid-base balance.
Inhalation:
Causes irritation of the mucous membrane and upper respiratory
tract.
Chronic:
May cause reproductive and fetal effects. Laboratory experiments
have resulted in mutagenic effects. May cause salicylism with effects
similar to those of skin absorption. May cause damage to the kidneys
and pancrease.

**** 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.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
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.
Notes to Physician:
Follow with gastric lavage with activated charcoal. If available,
administer ferric hexacyanoferrate as a gastrointestinal trapping
agent. Persons with pre-existing skin disorders, eye problems, or
impaired kidney function may be more susceptible to the effects of
this substance.

**** 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. Dusts at sufficient concentrations can form
explosive mixtures with air. During a fire, irritating and highly
toxic gases may be generated by thermal decomposition or combustion.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Water or foam may cause frothing. Use agent
most appropriate to extinguish fire.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid generating dusty conditions. Remove all sources of
ignition. Provide ventilation.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Avoid ingestion and inhalation.
Storage:
Keep away from sources of ignition. Do not store in direct sunlight.
Store in a cool, dry, well-ventilated area away from incompatible
substances. Store protected from moisture.

**** 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 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 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.
