**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Contact with acids liberates very toxic gas.
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:
Harmful if swallowed. May cause irritation of the digestive tract.
May cause liver and kidney damage. May cause cardiac disturbances.
Metabolism may release cyanide, which may result in headache,
dizziness, weakness, collapse, unconsciousness and possible death.
May cause central nervous system effects. Ingestion may result in
symptoms similar to cyanide poisoning which is characterized by
asphyxiation.
Inhalation:
May cause respiratory tract irritation. May cause liver and kidney
damage. May cause adverse central nervous system effects including
headache, convulsions, and possible death. May cause cardiac damage.
Inhalation may result in symptoms similar to cyanide poisoning which
include tachypnea, hyperpnea (abnormally rapid or deep breathing),
and dyspnea (labored breathing) followed rapidly by respiratory
depression. Pulmonary edema may occur.
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.
**** 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. Immediately 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 breathing
is difficult, give oxygen. Get medical aid. 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.
Notes to Physician:
Exposure should be treated as a cyanide poisoning. 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. Containers
may explode when heated. Non-combustible, substance itself does not
burn but may decompose upon heating to produce irritating, corrosive
and/or toxic fumes. Runoff from fire control or dilution water may
cause pollution.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Do NOT get water
inside containers. For small fires, use dry chemical, carbon
dioxide, or water spray. For large fires, use water spray, fog or
regular foam.
**** 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. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Keep container tightly closed. Avoid ingestion
and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Poison room
locked.
**** 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

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.
