**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation, in contact with skin and if
swallowed. Irritating to eyes.
Potential Health Effects
Eye:
Causes eye irritation. Lachrymator (substance which increases the
flow of tears). May produce superficial reversible injury.
Skin:
Causes mild skin irritation. If absorbed, causes symptoms similar to
those of inhalation. May be harmful if absorbed through the skin. May
be metabolized to cyanide which in turn acts by inhibiting cytochrome
oxidase impairing cellular respiration.
Ingestion:
May cause tissue anoxia, characterized by weakness, headache,
dizziness, confusion, cyanosis (bluish skin due to deficient
oxygenation of the blood), weak and irregular heart beat, collapse,
unconsciousness, convulsions, coma and death. Metabolism may release
cyanide, which may result in headache, dizziness, weakness,
collapse, unconsciousness and possible death.
Inhalation:
May cause respiratory tract irritation. May cause lung damage. May
be harmful if inhaled.
Chronic:
May be metabolized to cyanide which in turn acts by inhibiting
cytochrome oxidase impairing cellular respiration. 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.
Animal studies indicate that the product may affect the liver and
kidneys.
**** 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 for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. 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:
Exposure should be treated as a cyanide poisoning. Effects may be
delayed. For methemoglobinemia, administer oxygen alone or with
Methylene Blue depending on the methemoglobin concentration in the
blood. 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. Methylene blue, alone or in
combination with oxygen is indicated as a treatment in nitrite
induced methemoglobinemia.
**** 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. Use water spray to keep fire-exposed containers
cool. Flammable liquid and vapor. Approach fire from upwind to avoid
hazardous vapors and toxic decomposition products. Vapors are
heavier than air and may travel to a source of ignition and flash
back. Vapors can spread along the ground and collect in low or
confined areas.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
**** 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. Remove all sources of ignition.
Provide ventilation. Evacuate unnecessary personnel. Approach spill
from upwind.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. 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. Do not pressurize, cut, weld, braze, solder, drill, grind,
or expose empty containers to heat, sparks or open flames. Use only
with adequate ventilation. Avoid breathing vapor or mist.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Keep from contact with oxidizing materials. Store in a
cool, dry, well-ventilated area away from incompatible substances.
Flammables-area. Store protected from moisture.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. 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.
