Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Reacts violently with water giving off flammable
gas which may explode. Water Reactive. Material will react with
water and may release a flammable and/or toxic gas. May react
violently or explosively on contact with water. May be ignited by
heat, sparks, and flame.
Extinguishing Media:
Do NOT get water inside containers. Cool containers with flooding
quantities of water until well after fire is out. DO NOT USE WATER
OR FOAM. For small fires, use dry chemical, soda ash, lime or sand.
For large fires, use dry sand, dry chemical, soda ash or lime or
withdraw from area and let fire burn.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Sweep up or absorb material, then place into a suitable clean, dry,
closed container for disposal. Avoid generating dusty conditions.
Remove all sources of ignition. Do not get water on spilled
substances or inside containers.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Empty containers retain product residue, (liquid
and/or vapor), and can be dangerous. Keep container tightly closed.
Keep away from heat, sparks and flame. Avoid ingestion and
inhalation. Do not allow contact with water. Do not pressurize, cut,
weld, braze, solder, drill, grind, or expose empty containers to
heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Water free
area.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 7789-78-8:
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
