Flammable Limits:                   LEL: Not Applicable              UEL:     Not Applicable

Autoignition Temperature:       534° F (279° C)              NFPA CLASS:  IIIB       

General Hazards: Contact with eyes causes immediate severe irritation of the eye and eyelids. Product will support combustion. Products of combustion include smoke, toxic fumes, oxides of carbon to include carbon monoxide, phosphorous oxides, and phosphine and sulfur oxides. 

Extinguishing Media

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

Fire Fighting Procedure

Self - contained respiratory equipment; cool containers to prevent pressure buildup and possible explosion when exposed

to extreme heat. Caution - material will support combustion!

Unusual Fire and Explosion Hazards:

Closed containers can explode due to buildup of pressure when exposed to extreme heat.

Hazardous Combustion Products:

Products of combustion include smoke, toxic fumes, oxides of carbon to include carbon monoxide, phosphorous oxides, phosphine and sulfur oxides.

Text Box: SECTION 6 – ACCIDENTAL RELEASE MEASURES

 

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED Product will support combustion. Avoid contact with eyes. Do not wash to sanitary sewer. Large spills - confine spill, soak up with approved absorbent, shovel product into approved container for disposal.

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, open flames. This material will support combustion. Keep this and other chemicals out of reach of children.

 

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 corrosion-resistant, explosion-proof ventilation equipment.

Personal Protection:
Respiratory Protection (Specify Type): 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 EN149 for complete regulations.

Protective Gloves: Neoprene, butyl or nitrile rubber gloves with cuffs.

Eye Protection: 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 prevent 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.
