ing sufficient to prevent inhalation of dust or fumes, and

contact with skin and eyes. Do not touch spilled material.

Gather up in a manner that does not raise dust; wet if nec-

essary. Contain spill with inert absorbent, collect, and

transfer carefully to containers for recovery or disposal.

Flush area of spill thoroughly with running water.

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. 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

and away from incompatible or combustible materials. Keep

air out of container. Keep container tightly closed. Inspect

frequently for signs of damage or leaking. Treat empty con-

tainers with caution; they may contain hazardous residues.



FIRST AID MEASURES

 Specific Measures:

Eyes: Flush eyes thoroughly with gently running water,

holding eyelids open while flushing, for five to ten (5-10)

minutes, or until no trace of chemical remains. Get medical

advice.

Skin: Remove contaminated clothing. Brush or wipe off dry

material. Flush skin with plenty of running water until no evi-

dence of chemical remains. If irritation develops get medical

attention.

Inhalation: Remove to fresh air. Give oxygen and get

medical attention for any breathing difficulty.

Ingestion: If the victim is alert and not convulsing, rinse

mouth thoroughly with water and give 2 to 4 glasses of wa-

ter to drink to dilute. If victim feels unwell, or if a large

amount has been ingested, get medical attention.
