                      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 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, nitrile, PVC
   -respiratory protection: Approved respirator, fume hood as appropriate
   -eye protection: Chemical safety goggles
   -clothing: Plastic apron, sleeves, 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.
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. Transfer to container and arrange removal by disposal company. Wash site of spillage thoroughly with
water and detergent.
Disposal: Follow all federal, provincial  and local regulations for disposal.
