**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if
swallowed.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be metabolized to cyanide which in
turn acts by inhibiting cytochrome oxidase impairing cellular
respiration.
Ingestion:
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. Large doses of cyanide may result
in suddden loss of consciousness and prompt death; small doses will
prolong the above symptoms 1 to 2 hours.
Inhalation:
May cause respiratory tract irritation. May be metabolized to
cyanide which in turns act by inhibiting cytochrome oxidase
impairing cellular respiration.
Chronic:
May be metabolized to cyanide which in turn acts by inhibiting
cytochrome oxidase impairing cellular respiration. 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:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water.
Remove contaminated clothing and shoes. Get medical aid. Wash
clothing before reuse.
Ingestion:
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:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
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. Combustion
by-products include oxides of nitrogen and hydrogen cyanide.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Avoid
contact with eyes, skin, and clothing. Keep container tightly closed.
Do not breathe dust. Use only with adequate ventilation.
Storage:
Store in a tightly closed container. 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:
Not available.
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.
