| CAS #
||% by Weight||OSHA PEL/ACGIH TLV|
|Polyurethane Foam||9009-54-5||100%||None established|
Polyurethane foam is a fully cross-linked reaction product of polyhydroxy polyol, toluene di-isocyanate, catalysts, surfactants, pigments, and water. Polyurethane foam product is a polymeric material consisting of repeating units of carbon, hydrogen, oxygen, and nitrogen.
PHYSICAL CHEMICAL CHARACTERISTICS
|Boiling point:||Not applicable|
|Vapor pressure (mm Hg):||Not applicable|
|Vapor density:||Not applicable|
|Density:||0.5 - 40 lb/ft3|
|Melting point:||450 - 500°F|
|Evaporation rate:||Not applicable|
|Solubility in water:||Insoluble|
|Appearance and odor:||Uniform cellular solid structure of varying colors with slight characteristic odor|
FIRE AND EXPLOSION HAZARD DATA
|Flash point:||Decomposition products flash at 500°F|
|Flammable limits:||Not applicable|
|NFPA sprinkler classification:||Extra hazard|
|Extinguishing media:||Dry chemical; Water; Carbon dioxide|
|Wear self-contained breathing apparatus in enclosed areas
|Unusual fire hazards:||If ignited, foam can produce rapid flame spread, intense heat, 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 source.|
|Conditions to avoid:||High temperatures; open flames; strong oxidizers (i.e., hypochlorites)|
|Incompatibility:||Strong oxidizing acids - will degrade
|Carbon monoxide; acetaldehyde, acrylonitrile, TDI, polymer fragments, oxides of nitrogen and hydrogen cyanide|
|Hazardous polymerization:||Will not occur|
HEALTH HAZARD DATA
|Route of entry:||Inhalation - Foam dust|
|Health hazards:||Coarse dust can cause mechanical irritation of lungs and eyes. Airborne dust is evaluated as a nuisance dust. If ignited, foam may decompose and emit toxic gases and respiratory irritants.
|Route of entry:||Eye - Foam dust|
|Health hazards:||Coarse dust can cause mechanical irritation to the eyes. If exposed, avoid rubbing eyes.
|Medical conditions aggravated by exposure:||None known
|Emergency first aid procedures:||
PRECAUTIONS FOR SAFE HANDLING AND USE
|Steps to be taken in case material is released or spilled: No special response required — sweep up.
|Waste disposal method:||Federal, state, and local authorities should be contacted before attempting any form of disposal.
|Safe handling and storage:||Warehousing of bun stock, sheets, rolls, and fabricated items should be stored under a fusible sprinkler system with a minimum of six feet clearance between stacks of foam and the sprinkler heads.
Do not store foam near any ignition sources such as exposed electrical or gas heating elements, open flames and exposed lights. Do not smoke in foam storage areas.
Do not allow foam scrap and cuttings to accumulate, and maintain clear aisles with adequate access to all storage areas and exits.
|Other precautions:||Notify local fire companies of presence of large quantities of foam.|
|Ventilation:||Local exhaust ventilation is recommended for those processing procedures that may generate foam dust and decomposition products. Examples of these processes include sawing, grinding, buffing and flame lamination, hot wire cutting, heat sealing and hot stamping.|
|Respiratory protection:||Should be selected based on identity and concentration of air contaminant. Only NIOSH-approved respirators for protection against the air contaminant of concern should be used.|
|Eye protection:||Recommended for those processing operations that may generate dust.|
Flexible polyurethane foam, like all organic materials, will burn if exposed to a sufficient heat source. The ignition temperature of polyurethane foam will vary depending on the product chemical formulation, but all polyurethane foams are combustible and can create a fire risk. Flexible polyurethane foams, once ignited, may degrade and melt to a combustible liquid, which may add to the fire involvement.
Terms such as “fire retardant,” “slow burning,” and “flame resistant” describe certain flammability properties and should not be regarded as denoting fire safety under all conditions. Small-scale fire tests are not intended to reflect hazards presented by these or any other material under real fire conditions.
Thermal decomposition products from polyurethane foams can be toxic and present a risk to humans who are exposed. This is true for all organic materials. Fire risks in varying degrees are common to all fires: heat, carbon monoxide, other toxicants, oxygen depletion and smoke. In fires involving polyurethane foam, particularly flexible foams, large quantities of dense smoke can be generated quickly.
Personnel involved in fire fighting should wear self-contained breathing apparatus and be aware of the exposure to toxic and potentially lethal gases. Standard fire-fighting equipment generally employed by authorized firemen is mandatory.
