 **** 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.
 
 Potential Health Effects
 Eye:
 Causes eye irritation.  May cause conjunctivitis, ulceration and
 turbidity of the cornea.
 Skin:
 Causes skin irritation. May cause skin sensitization, an allergic
 reaction, which becomes evident upon re-exposure to this material.
 In the presence of moisture, this material may be absorbed through
 the skin. If absorbed, may cause symptoms similar to those for
 ingestion.
 Ingestion:
 May cause irritation of the digestive tract. May cause liver and
 kidney damage. Ingestion of thiocyanates may cause disorientation,
 weakness, low blood pressure, confusion, psychotic behavior,
 muscular spasms, convulsions, and death.
 Inhalation:
 May cause effects similar to those described for ingestion. Exposure
 produces central nervous system depression. Causes irritation of
 mucous membrane. At high concentrations, isocyanates affect mucous
 membranes of the respiratory tract and may lead to fatal pulmonary
 edema. Exposure to low and often even unmeasurable isocyanate
 concentration results in sensitization. In rare instances, exposure
 may cause sensitization, resulting in inflammation of the mucous
 membranes and in eczematous eruptions.
 Chronic:
 May cause liver and kidney damage. Effects may be delayed. May cause
 lung damage. Repeated or prolonged exposure may cause allergic
 reactions in sensitive individuals. Inhalation of product may
 aggravate existing chronic repiratory problems such as asthma,
 emphysema or bronchitis.
 
 **** 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
 immediately. Do NOT allow victim to rub eyes or keep eyes closed.
 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. Destroy contaminated shoes.
 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 immediately.
 Inhalation:
 Remove from exposure and move 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.
 Notes to Physician:
 For ingestion, the stomach sould be intubated, aspirated, and
 lavaged with a slurry of activated charcoal--protect the airway from
 aspiration of gastric contents.
 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.
 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:
 Wash area with soap and water. 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. Use with adequate ventilation.
 Minimize dust generation and accumulation. Avoid contact with eyes,
 skin, and clothing. Avoid ingestion and inhalation. Store protected
 from light. Discard contaminated shoes.
 Storage:
 Do not store in direct sunlight. Keep container closed when not in
 use. Store in a cool, dry, well-ventilated area away from
 incompatible substances. 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.
 Exposure Limits
 CAS# 593-84-0:
 
 
 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.
