**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes and skin.Hygroscopic.
Potential Health Effects
Eye:
Produces irritation, characterized by a burning sensation, redness,
tearing, inflammation, and possible corneal injury. May cause
chemical conjunctivitis.
Skin:
May cause irritation with burning pain, itching and redness.
Substance is rapidly absorbed through the skin.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause liver and kidney damage. May cause garlic smell
on the breath and body.
Inhalation:
May cause respiratory tract irritation. Can produce delayed
pulmonary edema.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. May cause
liver and kidney damage. Effects may be delayed.
**** 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.
Skin:
Get medical aid. Flush skin with plenty of soap and water for at
least 15 minutes while removing contaminated clothing and shoes. Wash
clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure to fresh air immediately. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid. Do NOT use mouth-to-mouth resuscitation.
Notes to Physician:
Treat symptomatically and supportively.
**** 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. Vapors may form an explosive mixture with air.
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. Vapors may be heavier than air. They
can spread along the ground and collect in low or confined areas.
Containers may explode when heated.
Extinguishing Media:
Cool containers with flooding quantities of water until well after
fire is out. 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.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Do not flush into a sewer. Clean
up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Provide
ventilation.
**** SECTION 7 - HANDLING and STORA
container. Keep from contact with oxidizing materials. Store in a
cool, dry, well-ventilated area away from incompatible substances.
**** 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 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.
