**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation, in contact with skin and if swallowed.
Contact with acids liberates very toxic gas.Hygroscopic.Light
sensitive.
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:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed. Metabolism may release
cyanide, which may result in headache, dizziness, weakness, collapse,
unconsciousness and possible death.
Inhalation:
May cause respiratory tract irritation. May be metabolized to
cyanide which in turns act by inhibiting cytochrome oxidase
impairing cellular respiration. 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. 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:
Flush skin with plenty of soap and water for at least 15 minutes
while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
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.
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. If
breathing has ceased apply artificial respiration using oxygen and a
suitable mechanical device such as a bag and a mask.
Notes to Physician:
**** 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. May react
with acids or moisture to form explosive hydrogen gas.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Use agent most appropriate to extinguish
fire.
**** 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:
Use with adequate ventilation. Minimize dust generation and
accumulation. Avoid prolonged or repeated contact with skin. Avoid
contact with eyes. Keep container tightly closed. Avoid ingestion and
inhalation. Store protected from light.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store
protected from moisture. Store protected from light.
**** 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 and clothing to
prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29CFR
1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator
when necessary.
