Section 3 Notes: Pentane is a flammable blowing agent that offgases from product, yet EPA document 540/3-90-020 states that 85% of the pentane is emitted within 48 hours of the start of the expansion process in the factory, with the remainder emitted over time. Considering manufacturer’s curing process, the vast majority of the 15% remainder of the pentane should be emitted prior to shipment, with the remainder being emitted during subsequent shipment, storage, and usage. Cyclopentane is a liquid below 120°F and isopentane liquefies at 82°F; n-pentane remains in a gaseous state above 97°F.
SECTION 4: FIRST AID MEASURES
Inhalation: No significant signs or symptoms indicative of any adverse health hazard are expected to occur as a result of inhalation exposure. Move person to fresh air. If irritation persists, seek medical attention.
Skin: No significant signs or symptoms indicative of any adverse health hazard are expected to occur as a result of absorption. Minor skin irritation is possible from abrasion.. Wash with mild soap and running water. Remove and launder contaminated clothing before reuse. If irritation develops, seek medical attention.
Eyes: May cause minor eye irritation. Flush eyes with running water for at least 15 minutes. Seek medical attention if irritation develops.
Ingestion: Ingestion of this material is unlikely. No significant signs or symptoms indicative of any adverse health hazard are expected to occur as a result of ingestion. If it does occur, do not induce vomiting; seek medical attention.

SECTION 5: FIRE-FIGHTING MEASURES
Upper Flammable Limit (UFL): Not applicable
Lower Flammable Limit (LFL): Not applicable
Flash Point: 600ºF to 650ºF
Auto Ignition Temperature: 914ºF
Extinguishing Media: Use dry chemical (ABC types), water spray, water fog, fire-fighting foam, or dry chemical or CO2 extinguishing media.
Special Fire Fighting Procedures: None
Unusual Fire And Explosion Hazards: No unusual conditions are expected after installation. Freshly expanded or heated foam may off-gas pentane, which can accumulate at hazardous concentrations above the Lower Flammable Limit (LFL) if stored in closed containers or confined areas. Electrostatic discharge can be a source of ignition of accumulated pentane vapors exceeding the LFL of 1.5% (15,000 ppm). Assure proper ventilation of storage or shipping containers to prevent accumulation of hazardous concentrations of off-gassed pentane. To prevent ignition, avoid smoking, keep from open flames and high temperatures. If heated above decomposition temperature or burned, product can emit an irritating dense black smoke and acid gases.
Hazardous Decomposition Products: Burning foam emits a dense, black, irritating smoke with acid gases. Primary combustion products are carbon monoxide, carbon dioxide and styrene. Other undetermined hydrocarbon fractions could be released in small quantities.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Land Spills: Scoop up material and put into suitable container for recycling or disposal as a non-hazardous waste.
Water Spills: This material will float on water and disperse with wind and current. Contain the material with booms, pick up or remove with a vacuum truck.
Air Release: This material will settle out of the air. Then proceed with the above measures for land or water spills
Personal Protective Equipment: Use appropriate personal protective equipment as necessary (see Section 8 for details).
SECTION 7: HANDLING AND STORAGE
Handling: Use protective equipment as described in Section 8 of this SDS when handling uncontained material. Avoid breathing dusts from this material.
Storage: Store in a well-ventilated area. Assure storage containers or areas and shipping containers are adequately ventilated. Avoid direct exposure to very high heat, open flame or other sources of ignition. Pentane vapors are heavier than air and may accumulate in low places. Keep material dry and protected from the elements. When stored outdoors, stack at least 4 inches above ground level and cover with tarpaulins or other suitable covering. Keep away from sources of ignition.
Other Precautions: None
SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls: Avoid unnecessary dust exposures when cutting or abrading.
Ventilation: Any dust-generating process should be performed in an area provided with either natural or mechanical ventilation as necessary to maintain exposures below occupational exposure limits and to prevent accumulation of hazardous concentrations of off-gassed pentane.
Respiratory Protection: Respiratory protection is not required under normal conditions of use. Use a NIOSH/OSHA-approved mask during fabrication if necessary. If dusts are generated up to 10 times above any occupational exposure limits, use a NIOSH-approved particulate respirator (disposablefiltering dust mask type) with an efficiency rating of N95 or higher (e.g. 3M’s 8210, Moldex 2300). Wear an air purifying respirator with charcoal cartridges or a supplied air respirator when exposure to pentane exceeds exposure limits.
Eye Protection: Safety glasses or goggles may be worn to reduce the risk of eye injury or irritation.
Skin Protection: Gloves, long sleeved shirt and long pants may be worn, as needed, to prevent skin contact andirritation.
Other Protective Clothing or Equipment: None

Volatile Organic Compounds (VOC):
- Pentane: EPS manufacturing uses beads as a raw material, and EPS beads typically contain 4%-7% pentane by weight, which is defined as a VOC by the EPA. EPA document 540/3-90-020 states that 85% of the pentane contained in the EPS bead is emitted within 48 hours starting with the expansion process (which occurs within the manufacturing facility). The remaining pentane is released over time, there is likely negligible pentane content in the foam by the time of installation.
- Styrene: Styrene is considered a VOC by the EPA. While Certificates of Analysis from bead suppliers typically do not state a styrene monomer content of EPS bead, several EPS bead suppliers have established that EPS beads typically contain styrene monomer, 900 to 1000 ppm by weight. After pre-expansion and expansion of beads, concentration should be considerably reduced.
