 **** SECTION 3 - HAZARDS IDENTIFICATION ****
 
 EMERGENCY OVERVIEW
 Harmful if swallowed.The toxicological properties of this material
 have not been fully investigated.
 
 Potential Health Effects
 Eye:
 May cause eye irritation.
 Skin:
 May cause skin irritation.
 Ingestion:
 May cause irritation of the digestive tract. The toxicological
 properties of this substance have not been fully investigated. May be
 harmful if swallowed.
 Inhalation:
 May cause respiratory tract irritation. The toxicological properties
 of this substance have not been fully investigated.
 Chronic:
 No information found.
 
 **** SECTION 4 - FIRST AID MEASURES ****
 
 Eyes:
 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. Flush skin with plenty of water for at least 15
 minutes while removing contaminated clothing and shoes. Wash clothing
 before reuse.
 Ingestion:
 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.
 Notes to Physician:
 Treat symptomatically and supportively.
 
 **** 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. Use water
 spray to keep fire-exposed containers cool. Combustible liquid.
 Vapors may be heavier than air.  They can spread along the ground and
 collect in low or confined areas. Containers may explode when heated.
 Extinguishing Media:
 In case of fire, use water, dry chemical, chemical foam, or
 alcohol-resistant foam. Use water spray to cool fire-exposed
 containers. 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. Clean up spills immediately,
 observing precautions in the Protective Equipment section. Remove all
 sources of ignition. Provide ventilation.
 
 **** SECTION 7 - HANDLING and STORAGE ****
 
 Handling:
 Wash thoroughly after handling. Remove contaminated clothing and
 wash before reuse. Use only in a well-ventilated area. 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. Avoid
 ingestion and inhalation. Do not pressurize, cut, weld, braze,
 solder, drill, grind, or expose empty containers to heat, sparks or
 open flames.
 Storage:
 Keep away from heat, sparks, and flame. Keep away from sources of
 ignition. Keep container closed when not in use. Store in a tightly
 closed container. Store in a cool, dry, well-ventilated area away
 from incompatible substances. Keep refrigerated. (Store below
 4C/39F.)
 
 **** 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# 103-64-0:
 
 
 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:
 A respiratory protection program that meets OSHA's 29
 CFR 1910.134 and ANSI Z88.2 requirements or European
 Standard EN 149 must be followed whenever workplace
 conditions warrant respirator use.
