SECTION 5 - 

FIRE FIGHTING MEASURES

NFPA Flammability
Classification:

OSHA/NFPA Class-IIIB combustible liquid.  Slightly combustible! 

Flash Point/Method: 

CLOSED CUP: 210°C(410°F).  (Pensky-Martens (ASTM D-93))  OPEN CUP: 
238°(460°F) (Cleveland.). 

Lower Flammable Limit: 

No data 

 

 

 

 

 

 

 

Upper Flammable Limit:  

No data 

Auto-Ignition Temp.: 

Not available 

Hazardous Comb 
ustion Products:

Carbon Dioxide, carbon monoxide, smoke fumes, unburned hydrocarbons and trace 
oxides of Sulfur and/or nitrogen. 

Special Properties: 

When heated above its flash point temperature, this material will release vapors which, if  
exposed to an ignition source, can ignite.  In enclosed spaces vapors can ignite with  

 

explosive force.  Mists or sprays may burn at temperatures below the flash point. 

Extinguishing Media:

 

Use dry chemical, foam, Carbon Dioxide or water fog. 

Fire Fighting Protective  
Clothing:

    

 

Firefighters must use full bunker gear including NIOSH-approved positive pressure self- 
contained breathing apparatus to protect against potential hazardous combustion or  

  decomposition products and oxygen deficiencies. 

SECTION 6 - ACCIDENTAL RELEASE MEASURES 

Take proper precautions to ensure your own health and safety before attempting spill control or clean-up.  For 
more specific information, refer to Emergency Overview on Page 1, Exposure Controls and Personal Protection 
in Section 8, and Disposal Considerations in Section 13 of this MSDS. 

Do not touch damaged containers or spilled material unless wearing appropriate protective equipment.  Slipping 
hazard; do not walk through spilled material.  Stop leak if you can do so without risk.  For small spills, absorb or cover 
with dry earth, sand, or other inert non-combustible absorbent material and place into waste containers for later 
disposal.  Contain large spills to maximize product recovery or disposal.  Prevent entry into waterways or sewers.  In 
urban area, cleanup spill as soon as possible.  In natural environments, seek cleanup advice from specialists to 
minimize physical habitat damage.  This material will float on water.  Absorbent pads and similar materials can be 
used.  Comply with all laws and regulations. 

SECTION 7 - HANDLING AND STORAGE 

Handling: 

Avoid water contamination and extreme temperatures to minimize product degradation.   
Empty containers may contain product residues that can ignite with explosive force.  Do not  
pressurize, cut, weld, brase solder, drill, grind or expose containers to flames, sparks, heat  

or other potential ignition sources.  Consult appropriate federal, state and local authorities  

before reusing, reconditioning, reclaiming, recycling or disposing of empty containers  
and/or waste residues of this product. 

Storage: 

Keep container closed.  Do not store with strong oxidizing agents.  Do not store at  
temperatures above 120°F or in direct sunlight for extend periods of time.  Consult  
appropriate federal, state, and local authorities before reusing, reconditioning, reclaiming,  
recycling or disposing of empty containers or waste residues of this product.
