**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes and skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
May cause digestive tract disturbances. The toxicological properties
of this substance have not been fully investigated. May be harmful if
swallowed.
Inhalation:
Causes respiratory tract irritation.
Chronic:
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
immediately.
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:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid immediately.
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:
Treat symptomatically and supportively.
**** 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. Use water spray to keep fire-exposed containers
cool. Containers may explode in the heat of a fire.
Extinguishing Media:
Use agent most appropriate to extinguish fire. 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:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation. Avoid
contact with eyes, skin, and clothing. Keep container tightly closed.
Avoid ingestion and inhalation.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels.
