4. FIRST AID MEASURES
First Aid Procedures
Inhalation
Move victim to fresh air. Call a Poison Centre or doctor if the victim feels unwell.
Skin Contact
Take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Wash gently
and thoroughly with lukewarm, gently flowing water and non-abrasive soap for 5 minutes. Call
a Poison Centre or doctor if the victim feels unwell.
Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 15-20
minutes, while holding the eyelid(s) open. If irritation or pain persists, see a doctor.
NEVER give anything by mouth if victim is rapidly losing consciousness, or is unconscious or
convulsing. DO NOT INDUCE VOMITING. Have victim rinse mouth with water. Immediately
call a Poison Centre or doctor.
If exposed or concerned, see a doctor for medical advice.

5. FIRE FIGHTING MEASURES
Flammable Properties FLAMMABLE SOLID.
Suitable Extinguishing Small fire: Carbon dioxide, dry chemical powder, appropriate foam, water spray or fog.
Media
Large fire: Use flooding quantities of water spray or fog.
Unsuitable
Extinguishing Media
None known.
Specific Hazards
Arising from the
Chemical
Gas or vapour may travel a considerable distance to a source of ignition and flash back to a
leak or open container.
In a fire, the following hazardous materials may be generated: very toxic carbon monoxide,
carbon dioxide.
Protective Equipment Use extreme caution.
and Precautions for
Firefighters should enter area wearing specialized protective equipment. (Bunker Gear will not
Firefighters
provide adequate protection.).
6. ACCIDENTAL RELEASE MEASURES
Personal Precautions Use the Personal Protective Equipment recommended in Section 8 of this MSDS. Increase
ventilation to area or move leaking container to a well-ventilated and secure area. Eliminate all
ignition sources. Use grounded, explosion-proof equipment.
Environmental
If the spill is inside a building, prevent product from entering drains, ventilation systems and
Precautions
confined areas. Do not allow into any sewer, on the ground or into any waterway.
Methods for
Containment and
Clean-up
Stop or reduce leak if safe to do so. Store recovered product in suitable containers that are:
tightly-covered.
7. HANDLING AND STORAGE
Handling
Storage
Avoid repeated or prolonged skin contact with product or with contaminated
equipment/surfaces. Only use where there is adequate ventilation. Avoid generating dusts.
Avoid generating vapours or mists. Eliminate heat and ignition sources such as sparks, open
flames, hot surfaces and static discharge. Post "No Smoking" signs.
Store in an area that is: dry, well-ventilated, out of direct sunlight and away from heat and
ignition sources, separate from incompatible materials (see Section 10: Stability and
Reactivity).
