Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
May cause irritation of the digestive tract.
Inhalation:
May cause respiratory tract irritation. May cause peripheral nervous
system effects. Exposure may cause blood abnormalities.
Chronic:
Prolonged or repeated inhalation may cause lung damage and/or
central nervous system disturbances.

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

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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Flammable
liquid and vapor.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Remove all sources of ignition.
Use a spark-proof tool. Provide ventilation.

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

Handling:
Wash thoroughly after handling. Use spark-proof tools and explosion
proof equipment. Avoid breathing dust, vapor, mist, or gas. Avoid
contact with skin and eyes. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Use only in a chemical
fume hood. Do not pressurize, cut, weld, braze, solder, drill, grind,
or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Flammables-area.

**** 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 only under a
chemical fume hood.
Exposure Limits
CAS# 69441-16-3:


Personal Protective Equipment

Eyes:
