4 EXPOSURE ROUTES : INTER UNIVERSITY RESEARCH BELGIUM A possible explanation of the results is that a large proportion of the increase in concentration is from percutaneous absorption. Probably the fireman are continuously exposed to PAHs through continuous exhalations of its contaminated clothing (PPE).

CONCLUSIONS

  • Cleaning with water and detergents is only

able to decontaminate:

  • MAX. 40% with 2 garments in the

machine

  • MAX. 15% with 3 garments in the

machine

  • Toxic compounds transfer from more

contaminated garments to the less contaminated garments during standard cleaning : CROSS CONTAMINATION

  • The clothing shows severe degradation

after frequent cleaning with standard processes

  • Environment !

STANDARD CLEANING TECHNOLOGIES BASED ON WATER AND DETERGENTS CAN NOT BE USED FOR THE DECONTAMINATION OF FIRE INTERVENTION GEAR

DECONTAMINATION – WHAT?

DECONTAMINATION : The reduction of all toxic products present in the clothing up to the legal maximum allowed quantities for this type of clothing. This without degrading the clothing and in an environmentally responsible manner.

FINAL CONCLUSION DECONTAMINATION

Fire suits that are in regular use must be subjected to maintenance (incl. complete decontamination) at least twice a year, for reasons of :

  • emptying the filter for toxic compounds

and thus avoid breaktrough to the skin

  • the killing of all micro-organisms, both for

hygienic and health reasons

  • applying the water/chemical-repellent

after-treatment as prescribed in European Standard EN 469

  • control of the general functionality

(visibility, protection, rescue system, ...) note: suits that have been exposed to very serious contamination must be decontaminated immediately
