**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation, in contact with skin and if swallowed.
Contact with acids liberates very toxic gas.Light
sensitive.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be absorbed through the skin in
harmful amounts. Allergic reactions have been reported.
Ingestion:
May cause irritation of the digestive tract. Ingestion of
thiocyanates may cause disorientation, weakness, low blood pressure,
confusion, psychotic behavior, muscular spasms, convulsions, and
death.
Inhalation:
May cause respiratory tract irritation. May be harmful if inhaled.
Chronic:
Thiocyanates used in drug therapy have caused nervous system effects
such as fine motor weakness of the arms and legs. Elevated levels of
thiocyanate in the blood will inhibit the uptake of iodine by the
thyroid gland resulting in thyroid effects. Prolonged absorption of
thiocyanates may produce various skin eruptions, running nose,
dizziness, cramps, nausea and vomiting.
**** 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, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. 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:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
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.
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:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid runoff into storm sewers and ditches which lead to
waterways. 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. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Keep container tightly closed. Avoid breathing dust.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep away from acids. 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

protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate 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.
