Lifespan / Number of uses

The lifespan of the undergarment

All fire clothing is negatively affected by gases, particles, heat, wear, washing etc., and how much the performance and function deteriorates is very dependent on various factors such as time, temperature, type of fire, type of smoke diving etc. and partly how the garments are washed.
Our undergarment is also affected and the biggest impact has the fire gas as it "saturates" the activated carbon, even so effectively that the saturation remains after washing. This clearly shows the efficiency of our undergarment but is also negative for the lifespan.
Laundry has some effect - much depending on the washing cycle, volume, type of detergent, etc. - but not so great impact as smoke and gas, so except the wear due to washing, our undergarment can be washed with almost retained function.
The independent tests performed by Chalmers, among others, show the following regarding protection factors and how the activated carbon becomes "saturated" during smoke diving (CPP compared to the standard regarding the amount of PAH):

New fire suit and new undergarment:
CPP has a protection factor that is about 220 times higher
Fire suit and undergarment after 12 smoke dives of 25 minutes each (total 300 minutes / 5 hours) including intermediate washes:
CPP has a protection factor that is about 66 times higher
Fire suit and undergarment after 24 smoke dives of 25 minutes ach (total 600 minutes / 10 hours) including intermediate washes:
CPP has a protection factor that is about 19 times higher

Due to these independent tests, our recommended lifespan is 20 smoke dives (500 minutes)1

A Swedish firefighter makes an average of 2 smoke diving operations2 + two smoke diver training courses per year, total 4 smoke dives per year, so for an average Swedish firefighter our recommended lifespan corresponds to

5 years of use3

____________________________________________________
1After 500 minutes (8 hours + 20 minutes), CPP's underwear still has a protection factor that is about 30 times higher than standard, but since we want firefighters to have the best possible protection, we think it is appropriate to change after 20 smoke dives.
2According to The Swedish Civil Contingencies Agency (MSB): In 2020, 10822 operations were made within "fires and fire incidents in buildings". In the same year, Sweden had 5051 full-time firefighters and 10847 part-time firefighters
3Calculated for personal undergarment, that is each firefighter has his own undergarment (20 smoke dives divided into annually two smoke diving operations + annually two smoke diving training courses)
