Foam Insulation Tanks (2-part compound)

Foam insulation tanks should not go into scrap metal because they contain a hazardous material and may be under pressure which could cause an explosion when they go through the shredder at the scrap metal yard. They should also never go in trash compactors.

If Foam Insulation tanks are not empty, they should be emptied before putting them in the bulky waste. Retain the hoses that they come with.

Instructions from Froth Pak:
The following procedure must be performed in a well-ventilated area or preferably outdoors. Never puncture or incinerate cylinders.
1. Wear the same PPE (personal protective equipment) as used while applying the two-component foam (i.e., NIOSH approved negative respirator with organic vapor cartridges and P-100 particulate filters, goggles/ face shield, gloves and protective clothing).
2. Liquids (“A & B”) remaining in the Froth-Pak™ kits must be disposed of as solid waste material, not liquid chemicals. Steps (3 thru 10) are intended guidelines necessary to convert any residual liquids into solids prior to proper disposal.
3. Carefully dispense liquids from the cylinders with the gun and nozzle attached. Dispense liquid materials out of the cylinder(s) as foam until one or both components/cylinder(s) are empty.
4. Carefully remove the nozzle from the gun and continue to depressurize the cylinder(s) by dispensing the liquid materials into a waste container lined with a plastic bag that has adequate absorbent (e.g., sawdust, kitty litter, dry absorbent) in the bottom.
5. Carefully close both cylinder valves completely, then operate the gun trigger to empty and depressurize the hoses.
6. Lift each cylinder. The cylinder should feel empty, with no sloshing of liquid.
7. Carefully remove the hoses from the cylinders. Use caution in case there is some residual chemical and/or pressure still in the hoses. Place hoses in plastic bag with absorbent material as in Step 4.
8. Carefully place cylinder(s) over a waste container lined with a plastic bag. Slowly open the valves on the cylinder(s) to catch any residual material. With cylinder pointed away from face, allow pressure to completely vent. Always handle and vent cylinders in a well-ventilated area while wearing proper respiratory protection.
9. Absorb any remaining liquids collected in Step 8 with dry oil-absorbent material as in Step 4. Once mixed thoroughly, it can be disposed of as ordinary industrial waste.
10. If the waste container contains an excess amount of “A” side versus “B” side, spray a small amount of water over the waste material but not enough to have a pool of liquid. Allow container and waste material in the plastic bag to vent while protected from the weather for 24-48 hours. After this time, tie the bag loosely and dispose of as trash. If waste contains more B side than A side, then mix the material with a stick to ensure all liquids are absorbed and dispose of as trash.
11. EMPTY and VENTED cylinders can be disposed of as bulky waste at town transfer stations.
