Text Box: SECTION 5 – FIRE FIGHTING MEASURES

 

 

Flash Point (Method used):                  63 F (17 C) TCC

Flammable Limits:                               LEL: 4.2 %  UEL:     12.9 %

Autoignition Temperature:                   869 F (465 C)              NFPA Class:     IB

 

General Hazards:         

Product is flammable. Products of combustion include compounds of carbon, hydrogen and oxygen, including carbon

monoxide. Vapors may cause a flash fire or ignite explosively. Vapors may travel a considerable distance to a source of ignition and flash back.

Extinguishing Media:

Carbon dioxide, water, water fog, dry chemical, chemical foam.

Fire Fighting Procedure:

Firefighters must wear full facepiece self - contained breathing apparatus in positive pressure mode. Do not use solid stream of water since stream will scatter and spread fire. Fine water spray can be used to keep fire - exposed containers cool.

Unusual Fire / Explosion Hazards:

Closed containers can explode due to buildup of pressure when exposed to extreme heat. Do not use direct stream of water on pool fires as product may reignite on water surface. Caution - Material is flammable!

Hazardous Combustion Products:

Smoke, fumes or vapors, oxides of carbon

Text Box: SECTION 6 – ACCIDENTAL RELEASE MEASURES

 

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: CAUTION - FLAMMABLE - Evacuate and ventilate area; remove all sources of sparks, ignition and open flames; confine and absorb into approved absorbent; place material into approved containers for disposal; do not wash to sewer or waterway.

Text Box: SECTION 7 – HANDLING AND STORAGE

 

 


PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Keep container closed when not in use; protect containers from abuse; protect from extreme temperatures. CAUTION - FLAMMABLE - keep away from all sources of ignition. "Empty" containers may contain residue which may form explosive vapors. Do not weld or cut near empty container that has not been professionally reconditioned. Use non sparking tools when opening and closing containers. Maintain well ventilated work areas to minimize exposure when handling this material.

 

Text Box: SECTION 8 – EXPOSURE CONTROLS / PERSONAL PROTECTION

 

Engineering Controls:

The use of local exhaust ventilation is recommended to control emissions near the source. Provide mechanical ventilation of confined spaces. Use explosion-proof ventilation equipment. See Section 2 for Component Exposure Guidelines.

Personal Protection
Respiratory Protection:

None required while threshold limits are kept below maximum allowable concentrations; if TWA exceeds standard workplace limits, NIOSH approved respirator must be worn. Refer to 29 CFR 1910.134 or European Standard EN 149 for complete regulations.

Protective Gloves:

Butyl rubber gloves with cuffs.

Eye Protection:

Protective eyeglasses or chemical safety goggles. Refer to 29 CFR 1910.133 or European Standard EN166.

Other Protective Clothing or Equipment:

Coveralls, apron, or other equipment should be worn to minimize skin contact, safety eyewash station nearby.

Work / Hygienic Practices:

Practice safe workplace habits. Minimize body contact with this, as well as all chemicals in general.
