SECTION IX SPECIAL PRECAUTIONS
(1993 EMERGENCY RESPONSE GUIDEBOOK, DOT P 5800.6, GUIDE PAGE NO. 44)
Precautions to be Taken Do not get in eyes, on skin, or on clothing. Avoid breathing mist. Use with
UNUSUAL FIRE AND in Handling & Storing adequate ventilation. Wash thoroughly after handling. Keep from contact with
EXPLOSION HAZARDS clothing and other combustible materials. Do not store near combustible materials.
Keep container tightly closed when not in use.
FIRE: Not combustible, but substance is a strong oxidizer and its heat of
reaction with reducing agents or combustibles may cause ignition. Can Read label on container before using. Do not wear contact lenses when working with chemicals.
Other Precautions
react with metals to release flammable hydrogen gas. EXPLOSION: Store in a tightly closed container. Remove and wash contaminated clothing
Reacts explosively with combustible organic or readily oxidizable promptly. Remove closure slowly to release pressure. Nitric acid is an oxidizer
and should not come in contact with cartridges and cannisters that contain
materials such as: alcohols, turpentine, charcoal, organic refuse, metal
oxidizable materials, such as activated charcoal.
powder, hydrogen sulfide, etc.
For laboratory use only. Not for drug, food or household use. Keep out of reach of children.
