inhalation, ingestion.
HYGIENE: Wash
hands and face before eating or drinking.
SECTION 7 PRECAUTIONS FOR SAFE HANDLING, STORAGE AND USE
SPILLS AND LEAKS: Use
extreme caution as contamination with organic or combustible material may cause
a fire or violent decomposition. If fire or decomposition occurs dilute with
water. Otherwise, sweep up all visible material using a clean, dry shovel and
broom and dissolve the material in water. Do no put back into the original
container. Either use or dispose of immediately.
STORAGE AND HANDLING: Store
in a cool, dry, well-ventilated area. Store in the original
tightly closed container. Keep away from heat sources, sunlight, or
ignition sources. Use a dry utensil for removing from the container. Close
immediately to prevent humidity contact. Any contamination may result in a
reaction leading to a fire or explosion. Add this product to water only.
WASTE DISPOSAL: Follow
recommendations of local, state and federal regulations.
EMPTY CONTAINERS: Rinse
