================== SECTION 3 - HEALTH HAZARDS IDENTIFICATION ===================

PRIMARY ROUTES OF EXPOSURE:

Skin contact.

EFFECTS OF ACUTE EXPOSURE: EYES: Direct contact with eyes may cause irritation.SKIN: Prolonged or repeated contact

may cause irritation.

INHALATION: Inhalation of vapor or mist can cause irritation of nose, throat and lungs and lead to headaches and

nausea.

INGESTION: Not an anticipated route of exposure. Small amounts are not expected to be harmful.CHRONIC HEALTH EFFECTS:

No anticipated chronic effects.MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE:

No known effects on other illnesses.

=========================                 SECTION 4 - FIRST AID MEASURES ======================

EYES: Flush with large amounts of water for 15 minutes, lifting upper and lower eyelids. If irritation persists seek

medical attention.

SKIN CONTACT: Wash contaminated area with soap and water. Remove and launder contaminated clothing.

INGESTION: If a large amount is ingested, give water or milk and induce vomitting. Seek medical attention.

INHALATION: Remove victim to fresh air and provide oxygen if breathing is difficult. If breathing has stopped

administer artificial respiration. Seek medical attention if condition persists.





================= SECTION 5 - FIRE AND EXPLOSION HAZARD DATA ===================

FLASH POINT: No flash                                       METHOD USED: PMCC

EXTINGUISHING MEDIA:

This material will not burn in its liquid state unless heated above its flash point. Dried films may burn and can be

extinguished by water spray, foam, dry chemical or carbon dioxide.

SPECIAL FIREFIGHTING PROCEDURES:

Persons exposed to products of combustion should wear self-contained breathing apparatus and full protective equipment.

Isolate danger area, keep unauthorized personnel out.

UNUSUAL FIRE AND EXPLOSION HAZARDS:

There is the possibility of pressure buildup in closed containers when heated. Water spray may be used to cool these

containers.





================== SECTION 6 - ACCIDENTAL RELEASE MEASURES ====================

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:

Do not let spilled or leaking material enter watercourse. May be toxic to aquatic life. Absorb with oil-dri or similar

inert material. Sweep or scrape up and containerize. Rinse affected area thoroughly with water. Wear appropriate

protective equipment.

==================== SECTION 7 - HANDLING AND STORAGE ==========================

HANDLING INFORMATION:

Employees who come in contact with this material must be trained in accordance to 1910.1200 of the Hazard Communicatin

Standard. Wear chemical resistant gloves and protective clothing to minimize contact. The use of respiratory

protection is advised when spraying because of mist and dust overspray.

STORAGE INFORMATION:

Keep containers tightly closed. Use and store material in cool, dry, well-ventilated areas away from heat, direct

sunlight, hot metal surfaces, and all sources of ignition. Post "No smoking or open flame" sign. Store only in

approved containers. Keep away from incompatible materials (see section 10). Protect containers against physical

damage. Indoor storage should meet OSHA standards and appropriate fire codes.

OTHER PRECAUTIONS:

All empty containers should be disposed of in an evironmentally safe manner in accordance with all governmental

regulations.





================ SECTION 8 - CONTROL MEASURES/PERSONAL PROTECTION ==============

RESPIRATORY PROTECTION:

No special requirements under normal use conditions. In confined areas, or ares with poor ventilation, engineering

controls should be used to minimize exposure. Use NIOSH/MSHA approved respirator if conditions warrant.

VENTILATION:

General room ventilation is adequate.

PROTECTIVE GLOVES:

Prevent prolonged or repeated contact by wearing chemical resistant gloves and other appropriate protective clothing.

Launder contaminated clothing before reuse.

EYE PROTECTION:

Wear safety glasses to reduce eye contact potential. Chemical safety goggles (ANSI Z87.1 or approved equivalent) are

appropriate if splashing is likely. Eye washes must be available where eye contact can occur.

OTHER PROTECTIVE CLOTHING OR EQUIPMENT:

A source of clean water should be available for flushing eyes and skin. Showers should be available if larger spills

are possible.

WORK/HYGIENIC PRACTICES:

Efforts should be made to minimize contact and spills. Always wash hands before eating, drinking, or smoking. Clean up

spills promptly. Follow OSHA and company guidlines.
