Waste Disposal: Follow all federal, provincial and local
regulations for disposal.
Handling Procedures and Equipment: Combustible, toxic
material. Workers must be thoroughly trained in the hazards
of this material and its safe use, and must wear appropriate
protective equipment and clothing. Use grounded,
non-sparking ventilation systems and electrical equipment.
Use non-sparking tools. Avoid generating dust. Keep away
from all sources of ignition or heat, and hot surfaces. Avoid
all contact and inhalation of vapours or dust. Use the small-
est amount possible for the purpose, in an area with
adequate ventilation. Empty containers may contain haz-
ardous residues; treat with caution.
Storage Requirements: Store in suitable, labelled contain-
ers, a cool, dry, well-ventilated area, out of direct sunlight,
and away from all ignition sources and incompatible materi-
als. Protect from damage, and inspect frequently for signs
of leaking.
FIRST AID MEASURES
Specific Measures:
Eyes: Brush or blot away excess chemical. Flush thor-
oughly with gently running water for at least fifteen (15)
minutes, holding eyelids open while flushing. Take care not
to flush contaminated water into unaffected eye. Get medi-
cal advice immediately.
Skin: Remove contaminated clothing, including watches,
rings, belts and shoes. Flush skin with plenty of running wa-
ter for at least fifteen (15) minutes. If irritation develops seek
medical attention. Decontaminate clothing before reuse, or
discard.
Inhalation: Remove to fresh air. Give oxygen for any
breathing difficulty. Get medical attention immediately.
