No information found.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Get medical aid. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
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. Strong oxidizer. Contact with other material may
cause fire. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Use water spray to
keep fire-exposed containers cool. Use water with caution and in
flooding amounts. Containers may explode when heated. Explosive
decomposition may occur under fire conditions.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Contact professional
fire-fighters immediately. Cool containers with flooding quantities
of water until well after fire is out. Use water spray, dry
chemical, carbon dioxide, or appropriate foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Remove all sources of ignition. Provide ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Keep container tightly closed. Avoid contact with clothing
and other combustible materials. Avoid ingestion and inhalation.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Store in a tightly closed container. Store in
a cool, dry, well-ventilated area away from incompatible substances.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 1923-70-2:

CAS# 7732-18-5:


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 gloves to prevent skin exposure.
Clothing:
Wear a chemical apron. 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.
