4. Fire and explosion hazard data


 


Flash Point:           Decomposition products flash at >500°F(1) Above 200°F(2)             LEL: None


Flammable Limits: Not Available                                                                                  UEL: None


Classification:       Combustible Solid


NFPA Sprinkler Classification:     Extra Hazard


Extinguishing Media:        CO2, foam, dry chemical, or water spray


Special Fire Fighting Procedures: Full protective equipment including self-contained breathing apparatus should be worn.


Unusual Fire & Explosion Hazards: If ignited, foam can produce rapid flame spread, intense heat and dense black smoke and toxic gases. Material can melt into a burning liquid that can drip and flow.  Accumulated polyurethane dust can be readily ignited and presents a fire risk.  High concentrations of dust in the air can explode if exposed to a flame, spark or other ignition sources. (1) HC1, C12, CO released upon combustion. (2)


 


5. Reactivity data


 


Stability:                            Stable


Conditions to Avoid:         Temperatures above 110°F, open flames, strong oxidizers (i.e. chlorates, bromates, nitrates, and hypochlorites) can cause discoloration to foam.


Incompatibility:                 Strong oxiding acids and bases – will degrade product.


Hazardous Decomposition


Products:                          Carbon monoxide, carbon dioxide, oxides of nitrogen, free isocyanate, acetaldehyde, acrylonitrile, polymer fragments, and hydrogen cyanide. (1) HC1, C12, CO. (2)           


Hazardous Polymerization:           Will not occur


 


6. health hazard data


 


Route of Entry:      Inhalation –       Foam dust


Health Hazards:     Coarse dust can cause mechanical irritation of the upper respiratory tract when concentrations are above the applicable occupational exposure limit.  Airborne dust is evaluated as a nuisance dust.  If ignited, foam may decompose and emit toxic gases and respiratory irritants.


                                                      Irritating Vapors


                              Irritating vapors (decomposition products) may be produced if product is exposed to high temperatures above 350°F.


                                          Eye -                Foam dust                               


Coarse dust can cause mechanical irritation to the eyes. If exposed, avoid rubbing eyes.


Irritating Vapors


                              Irritating vapors (decomposition products) may be produced if product is exposed to high temperatures above 350°F.


Carcinogenicity:    NTP:                            No        IARC Cancer Review:  No


                              OSHA Regulated:        No        IARC:                           No


Medical Conditions Aggravated by Exposure:       None known


Emergency First Aid Procedures:


Inhalation:         Remove to fresh air, contact physician if respiratory discomfort persists.


                  Eyes:               Flush eyes thoroughly with water for 15 minutes


                  Skin:                None necessary


                  Indigestion:       None necessary


7. precautions for safe handling and use


 


Steps to be Taken in Case


Material is Released or Spilled:     No special response required.


Waste Disposal Method:                Dispose of in accordance with Federal, State, and Local environmental regulations.


Safe Handling and Storage:           Do not store near high temperature sources, any ignition sources such as exposed electrical or gas heating elements, open flames and exposed lights.  Do not smoke in storage areas.


Other Precautions:                        Notify local fire companies of presence large quantities of foam.


 


8. Control Measures


 


Respiratory Protection:     Should be selected based on the identity and concentration of air contaminant.  Only NIOSH-approved respirators for protection against the air contaminant of concern should be used.


Ventilation:                        Local exhaust ventilation is recommended for those processing procedures that may generate foam dust and decomposition products.


Eye Protection:                 Safety Glasses recommended for those processing operations that may generate dust.


Skin Protection:                Use adequate hand protections during hot processing operations.  Use guards and/or protective gloves for cutting operations.
