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

EMERGENCY OVERVIEW
Irritating to eyes and skin.

Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
Causes skin irritation. May cause cyanosis of the extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Metabolism may release cyanide, which may result in
headache, dizziness, weakness, collapse, unconsciousness and
possible death.
Inhalation:
May cause respiratory tract irritation. Aspiration may lead to
pulmonary edema. Can produce delayed pulmonary edema. May be
metabolized to cyanide which in turns act by inhibiting cytochrome
oxidase impairing cellular respiration. Inhalation at high
concentrations may cause CNS depression and asphixiation.
Chronic:
May be metabolized to cyanide which in turn acts by inhibiting
cytochrome oxidase impairing cellular respiration. Effects may be
delayed. Chronic exposure to cyanide solutions may lead to the
development of a "cyanide" rash, characterized by itching, and by
macular, papular, and vesicular eruptions, and may be accompanied by
secondary infections. Exposure to small amounts of cyanide compounds
over long periods of time is reported to cause loss of appetite,
headache, weakness, nausea, dizziness, and symptoms of irritation of
the upper respiratory tract and eyes.

**** 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 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 and move 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. May be partially metabolized
to cyanide in the body.
Antidote:
Always have a cyanide antidote kit on hand when working with cyanide
compounds. Get medical advice to use.

**** 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. Use water
spray to keep fire-exposed containers cool. Combustible liquid.
Vapors may be heavier than air. They can spread along the ground and
collect in low or confined areas. Containers may explode when heated.
Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers.

**** 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. Use a spark-proof tool. Provide ventilation.

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

Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Avoid contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Keep
container tightly closed. Keep away from heat, sparks and flame.
Avoid ingestion and inhalation. Wash clothing before reuse. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container.

**** 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.
Exposure Limits
CAS# 620-22-4:


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 and clothing to
prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
