Hello, we have a dried raw material storage facility that needs insulation installed, and we have a Huntsman "Heatlok® HFO high lift" closed-cell spray foam material that we are looking at using.  The facility is at our storage location that is not SQF-certified, though we are SQF-certified at our manufacturing location.  We manufacture dietary supplements in the US under 21 CFR Part 111 and have NSF GMP certification.  What are the requirements as far as removing all product from the facility and covering the insulation material, or does it just remain exposed insulation above product?

 

Thank you,
Matthew

Covering the insulation is a must and I suggest you read the attached (from a general innerwebs search) there is plenty of information suggesting that yes you should remove your materials as well as address human safety as well.

Yes do remove all product while the foam insulation is applied, that can be a messy business. Lots of small particulate floating around. Once applied the insulation will indeed need to be covered, because it will deteriorate over time and fall all over your product.

The easiest way to cover the foam would be a 15-minute thermal coating. (Intumescent paint)

It looks like paint, but will prevent foam from heating up/burning quickly.

 

Here are a few options. Your foam installer may have their own recommendation.

Most of these coatings can be rolled or sprayed. If you let the foam company spray it, you will save a ton of time.

The product application guide says that you will need to cover the insulation with a 15-minute thermal barrier, which is required by the IBC, as well as OSHA. Your site's insurance provider will also likely require the foam to be covered. 

 

The installers are required to have respiratory PPE due to the mists and vapors involved. That should give you an indication that you don't want those to come into contact with your equipment or materials. So all of those items should be removed. I also suggest cleaning the areas where the spray foam was installed prior to bringing the equipment back into the area. And to clean and sanitize again prior to resuming use--especially your mobile equipment (forklifts, pallet jacks, carts).

As others have said, it's important to move what you can to minimize chemical and foreign material risks.

If you have anything that cannot be moved, like pallet racks or floor mounted equipment, you can use this.

You will have to be very thorough and make sure everything is covered all the way to the floor.

Wide blue painters tape works great. 

 

Take pictures to prove that everything was covered. Good luck!
