federal, provincial and local regulations.
Handling Procedures and Equipment: COMBUSTIBLE
DUST. Workers using this chemical must be properly
trained in its hazards and its safe use, and must wear appro-
priate protective equipment and clothing. Avoid generating
dust. If there is dust, keep away from heat, sparks, and all
sources of ignition; avoid the accumulation of static charge,
use anti-sparking tools and ground and bond equipment and
containers. Use the smallest amount possible for the pur-
pose, in a designated area with adequate ventilation. Use
good housekeeping to prevent accumulations of dust. Avoid
contact with skin and eyes. Avoid inhalation. Wash thor-
oughly after handling.
Storage Requirements: Store in suitable, labelled contain-
ers, in a cool, dry, well-ventilated area, out of direct sunlight.
Store away from incompatible materials. Keep containers
tightly closed when not in use and when empty. Protect
from damage, and inspect frequently for signs of leaking.
