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

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

Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Harmful if absorbed through the skin. May be
metabolized to cyanide which in turn acts by inhibiting cytochrome
oxidase impairing cellular respiration.
Ingestion:
Harmful if swallowed. May cause irritation of the digestive tract.
Metabolism may release cyanide, which may result in headache,
dizziness, weakness, collapse, unconsciousness and possible death.
Ingestion may result in symptoms similar to cyanide poisoning which
is characterized by asphyxiation.
Inhalation:
May be fatal if inhaled. May cause effects similar to those
described for ingestion.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion.

**** 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.
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Remove all contaminated clothing immediately. Treat patient as for
inhalation.
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. SPEED IS ESSENTIAL.
A DOCTOR MUST BE NOTIFIED AT ONCE. Treat patient as for inhalation.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation.
If breathing has ceased apply artificial respiration using oxygen and
a suitable mechanical device such as a bag and a mask. SPEED IS
ESSENTIAL, OBTAIN MEDICAL AID IMMEDIATELY.
Notes to Physician:
Exposure should be treated as a cyanide poisoning.
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. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam. Do
NOT use straight streams of water.

**** 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Do not get in eyes,
on skin, or on clothing. Keep container tightly closed. Do not ingest
or inhale.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.

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

Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 140-29-4:
United States OSHA: 5 mg/m3 TWA (listed under Cyanide anion).
Germany: (listed as cyanide anion): Skin absorber
Netherlands: (listed as cyanide anion): 5 mg/m3 MAC (as CN)
Russia: 0.8 mg/m3 TWA

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:
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.
