Test No. 4, Nov 2021:

The purpose of the test was to determine the degree of protection offered by the tested garments
against exposure to polyaromatic hydrocarbons (PAH) in fire smoke – after use during a total of 24 smoke dives (600 minutes/10 hours), with conventional washing and drying cycles of both standard outer garments and the adsorptive undergarment between the smoke diving events. The study has been carried out August 2021 under the leadership of CIT Energy Management AB (subsidiary of Chalmers Industriteknik), IVL (Swedish Environmental Institute) and Lund University. The test site was the Rescue Service's training site Guttasjön outside Borås (Sweden).

Summary of Test 4:
The tests show that
-The tested adsorptive undergarment reduced the PAH penetration through the clothing
system substantially.
-After 24 smoke diving events, comprising a total of 600 minutes exposure to wood smoke,
the protection factor was found to be about 132 for the garment comprising adsorptive
underwear, compared to about 7 for the standard garment.
-The penetration of PAHs is roughly twenty times lower through the used adsorptive garment
combination, compared to the standard garment combination.

Test No. 1-3, May 2021:

Report that summarizes the results from Tests no. 1-3, which were carried out 2019 and 2020 under the leadership of CIT Energy Management AB (subsidiary of Chalmers Industriteknik), IVL (Swedish Environmental Institute) and Lund University. The test site was the Rescue Service's training site Guttasjön outside Borås (Sweden). The purpose of the test No 3 was to investigate the properties of CPP's undergarments (the adsorption possibilities of hazardous PAH-gases and -particles) after 10 smoke diving exercises including intermediate washes, to be compared to the results of new unused undergarments.

Summary of test 1-3:
The protection factor against PHA for the combination new unused CPP undergarment + fire suit (EN469), was measured to 3300. The protection factor against PAH for the combination used* CPP undergarment + fire suit (EN469) was measured to 660. *Used means 10 smoke diving exercises including intermediate washes.
To be compared the protection factor against PHA for the combination standard new undergarment + fire suit (EN469) which was measured to 15.
