**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes and skin. May cause sensitization by skin
contact. Harmful by inhalation.Possible risk of irreversible effects.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
Vapor or mist is irritating to the mucous membranes and upper
respiratory tract.
Chronic:
Prolonged or repeated skin contact may cause dermatitis.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with soap and plenty of
water. Remove contaminated clothing and shoes. Get medical aid if
symptoms occur. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
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. Wash area with soap and water.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Use
only with adequate ventilation. Avoid breathing vapor or mist.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do NOT
freeze.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
Exposure Limits
