Handling Procedures and Equipment: May be COMBUS-
TIBLE DUST. Use routine safe handling procedures.
Personnel working with this product should be trained in its
hazards and its safe use, and should wear appropriate pro-
tective equipment and clothing. Avoid generating dust. Use
the smallest amount possible for the purpose, in a desig-
nated area with appropriate ventilation. Keep work areas
free of incompatible materials. Keep away from excessive
heat, and all ignition sources. If dust is present, use
non-sparking tools, post 鈥淣o Smoking鈥? signs. Avoid all con-
tact and inhalation. Wash thoroughly after working with this
chemcial. Keep containers closed when not in use.
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 exposure to light and air. Protect from damage, and in-
spect frequently for signs of leaking.
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 if irritation develops.
Skin: Remove contaminated clothing, including watches,
rings, belts, and shoes. Flush skin with plenty of running
water for five to ten (5-10) minutes. Get medical advice if irri-
tation develops.
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.
