Wash site of spillage thoroughly with water and detergent.
Waste Disposal: Follow all federal, provincial and local
regulations for disposal.
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, away from sources of
ignition,and incompatible or combustible materials. Keep
containers tightly closed when not in use and when empty.
Protect from damage.
FIRST AID MEASURES
Specific Measures:
Eyes: Flush eyes thoroughly with running water for five to
ten (5-10) minutes, or until no trace of chemical remains,
holding eyelids open while flushing. Get medical advice if ir-
ritation persists.
Skin: Brush or wipe off dry material. Flush skin thoroughly
with running water until no trace of chemical remains. Get
medical attention if irritation develops.
Inhalation: Remove to fresh air. Give oxygen and get
medical attention for breathing difficulty.
Ingestion: If victim is alert and not convulsing, give 2 to 4
glasses of water to dilute material. If vomiting occurs, rinse
mouth and give more water to drink. If victim feels unwell,
or if a large amount has been ingested, get medical atten-
tion.
