Safety Tips for Handling Extruded Polyethylene Foam
Policy Statement
Nomaco K-Flex is dedicated to quality and safety and we take product stewardship and safe handling
of our products seriously. Nomaco K-Flex produces polyethylene foam products with customer
satisfaction as a primary objective. Our products are designed to provide you with consistently high
quality to meet your business demands. Our foam products use a blowing agent as part of the
manufacturing process to convert polyethylene plastic into foam products for your application. Without
proper precautions, it is possible to create and ignite flammable concentrations of blowing agent in air.
The following recommendations are designed to inform you of the precautions that need to be followed
to insure the highest possible level of safety while using our products.
General Handling
Nomaco K-Flex is listing precautions and recommendations to help you maintain the highest possible
level of safety when receiving, unloading, storing, handling, fabricating and shipping our polyethylene
foam products. Always refer to the Material Safety Data Sheet (MSDS) for additional safety
instructions.
Shipping Considerations
Nomaco K-Flex transports foam using ventilated truck trailers, railcars and other transport vehicles to
assure that flammable concentration of blowing agent released from the foam does not develop inside
the vehicle.
Nomaco K-Flex will not load solid-sided truck trailers unless they are equipped with appropriate vents.
The minimum vent requirement for truck trailers are:
1. Minimum vent size is 15 square inches per 1000 cubic feet of transport vehicle space, both front
and rear of vehicle.
2. One vent should be places low at one end of the trailers in the rear (tail) of the trailer.
3. A second vent should be placed high at the other end of the front (nose) of the trailer.
4. Vents must be unobstructed a minimum of 6 inches front and rear of the transport vehicle.
5. Vents must be permanently open, or must be capable of being locked or sealed in the open
position by the shipping crew.
Nomaco K-Flex will not accept foam shipments, including returned goods, which have been shipped in
unventilated transport vehicles.
Opening of Vehicles Containing Foam
Although shipment in properly ventilated trailers and other vehicles should precent the accumulation of
a flammable concentration of blowing agent during transport, the following additional precautions
should be taken when opening shipments of foam or other vehicles being used to store foam:
1. Extinguish all smoking or other ignition sources.
2. Verify vehicle vents are open.
a. If vehicle vents are not open, open the vents and allow air circulation in the vehicle for at
least 10 minutes.
3. Always allow air circulation in the vehicle for at least 10 minutes after opening the vehicle doors
before entering vehicle or moving foam.
Foam Packaging, Storing and Shipping
Foam should be stored only in ventilated areas. Foam should NOT be stores in closed, unventilated
areas. Foam should not be stored in trailers. Smoking and all other ignition sources should NOT be
allowed in foam storage areas.
Material Safety Data Sheet Product: Foam Plastics
MSDS-PE-11/06 Issued Date: 04/10/07
Page 7 of 9 Prepared Date: November 1, 1996
Foam part being packaged for shipment should be placed in containers which will allow blowing agent
to escape. Plastic bags should be adequately ventilated.
Foam Remnants (Scrap)
Foam remnants and scrap pieces should be stored in ventilated areas. Smoking and all other ignition
sources should NOT be allowed in area where parts or scrap are being stored or loaded into vehicles.
Foam remnants and scrap parts being packaged for disposal or recycling should be placed in
containers which will allow blowing agent to escape. Plastic bags should be adequately ventilated.
Foam Fabrication
Fabricated parts may initially release blowing agent at higher rates than the same piece of foam prior to
fabrication because interior surfaces have been exposed. The blowing agent release rate then
decreases significantly in the days following fabrication. The release rate varies considerably with the
foam product fabricated, the size and shape of the part, the age of the foam, and the storage
temperature of the fabricated part. Operations which cut or destroy cells (such as skiving, die cutting,
routing and grinding) release blowing agent. Flammable concentration of blowing agent in air may
develop in localized areas where large numbers of cells are being cut. Blowing agent released should
be diluted with air to dissipate blowing agent in these localized areas. Never smoke or use other
ignition sourced while handling or working with foam.
Thermal Fabrication and Lamination
To prevent buildup of blowing agent, air flow should be provided in areas of thermal fabrication
and lamination. To minimize potential ignition hazards, foam and heat/flame sources should be
kept moving in relation to each other.
Skiving
Flammable concentrations of blowing agent are possible between the two split layers of foam as
they emerge from the skiver. Air flow should be directed into the space behind the blade guide,
between the two split foam layers. Airflow should also be provided in any areas where foam is
stacked or stored after skiving operations.
Die Cutting/Band Sawing
To prevent the buildup of blowing agent, air flow should be provided in the die press and band
saw areas. Airflow should also be provided in the areas where foam is stacked and stored after
cutting operations.
Grinding/Routing/Shaping
Equipment should be purged with sufficient volume of air to assure released blowing agent does
not reach a flammable concentration. Positive air purge should be provided in any bins or
hoppers which receive the shreddings from these operations. Collection systems should be
monitored to ensure that high blowing agent concentrations will not occur when operations sit
idle as a result of temporary shut down or malfunction.
Reprocessing Foam Scrap
Grinding and/or densifying operation release residual blowing agent while reprocessing polyethylene
foam parts and foam scrap. Because of the potential to achieve flammable concentrations of blowing
agent in these operations, DO NOT REPROCESS FOAM PARTS OF FOAM SCRAP UNLESS USING
A REPROCESSING SYSTEM WHICH IS APPROPRIATELY DESIGNED AND OPERATED IN A FAIL-
SAFE MANNER TO PREVENT THE CREATION OF A FLAMMABLE CONCENTRATION OF
BLOWING AGENT IN AIR.
Material Safety Data Sheet Product: Foam Plastics
MSDS-PE-11/06 Issued Date: 04/10/07
Page 8 of 9 Prepared Date: November 1, 1996
While you need to independently judge and analyze your operation, we believe the minimum air supply
for a reprocessing system is at least 50 cubic feet per minute of adequately mixed positive air flow for
every cubic foot per minute of foam fed into these reprocessing systems.
Adequate air must be supplied throughout the entire reprocessing system, including any storage bins or
hoppers receiving output from the reprocessing system. Reprocessing and collection systems must be
monitored to ensure that high blowing agent concentrations do not occur during normal operations,
temporary shutdown or malfunction.
Each reprocessor should also use his own independent judgment regarding the safety of reprocessing
foam parts or scrap in his facility. We strongly recommend that you consult with your equipment
manufacturer or contact a qualified party to obtain specific equipment recommendations for your facility
if you plan to reprocess, grind, or densify foam parts or scrap.
Although the blowing agent release rate decreases significantly in the days following foam fabrication,
we recommend that you ship fabricated parts and foam scrap in ventilated truck trailers or other
ventilated transport vehicles. These vehicles should be ventilated in the same way as vehicles used for
shipping unfabricated foam. Our products can be safely used in your operations as long as you keep
foam away from ignition sources and provide adequate air circulation and ventilation in all areas where
foam is shipped, unloaded, stored, handled and fabricated.
Summary
Government entities may mandate adequate ventilation of the general workplace and storage areas to
assure proper industrial hygiene. Where adequate ventilation is provided to satisfy industrial hygiene
requirements, flammable concentrations of blowing agent should not develop. Always refer to the
Material Safety Data Sheet (MSDS) for additional safety instructions. Please contact us with any
questions you may have regarding the safe handling of our products.
