                      Section VII First aid measures
======================================================================================
Skin: Flush the contact area with lukewarm running water for at least 15 minutes. Remove contaminated clothing, taking care not to spread the chemical. If contamination is extensive, remove clothing under running water. Discard or decontaminate clothing under running water. Discard or decontaminate clothing before use. Unless contact has been slight, seek medical attention. Seek medical attention if irritation persists.
Eye: Flush the contaminated eye (s) for at least 15 minutes with lukewarm running water, holding the eyelids open. Take care not to rinse contaminated water into the non-affected eye. Always seek medical attention for accidents involving the eyes.
Inhalation: Take proper precautions to ensure your own safety before attempting rescue. Remove source of contamination or move victim to fresh air. If breathing has stopped, trained personnel should begin artificial respiration, or if the heart has stopped, cardiopulmonary resuscitation (CPR) immediately. Seek medical attention.
Ingestion: Never give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. Rinse mouth thoroughly with water. If victim is conscious, induce vomiting. Have victim drink 200-400 ml of water to dilute. If breathing has stopped, trained personnel should begin artificial respiration, or if the heart has stopped, cardiopulmonary resuscitation (CPR) immediately. Seek medical attention.

                     Section VIII Preventive Measures
======================================================================================
Engineering Controls: Engineering control methods to reduce hazardous exposures are preferred. Methods include mechanical ventilation (dilution and local exhaust), process or personnel enclosure, control of process conditions, and
process modification. Administrative controls and personal protective equipment may also be required. 
Personal protective equipment:
   -gloves: Rubber, neoprene or equivalent
   -respiratory protection: Fume hood, approved respirator as appropriate
   -eye protection: Chemical safety goggles
   -clothing: Plastic apron, sleeves and boots as appropriate
Storage Requirements: Store in suitable labeled containers. Keep containers tightly closed when not in use and when empty. Protect from damage. Store in a cool, dry, well-ventilated area, out of direct sunlight. Store away from incompatible materials.
Handling Procedures and Equipment: Follow routine safe handling procedures.
Leak or Spill Clean-up: Before dealing with spillages take necessary protective measures, inform others to keep at a safe distance and, for flammable materials, shut off all possible sources of ignition. Apply bleaching powder or sodium hypochlorite liberally to liquid spillage, transfer to container and allow to stand for 24 hours. For spillage of solid, carefully transfer to
container of large volume of water, add an excess of sodium hypochlorite and allow to stand for 24 hours. Arrange removal by disposal company. 
Disposal: Follow all federal, provincial  and local regulations for disposal. Use only licensed disposal and waste hauling companies. Disposal of small amounts of spilled material may be handled as described under "Leak or Spill
Cleanup". Large spills must be dealt with separately and must be handled by qualified disposal companies.
Special Shipping Information: Follow all TDG regulations and see classification in Section I
