  • Powered respirator and loose-fitting hood provide cooling air over the head and through the suit, making the wearer more comfortable and better able to focus on tasks
  • The loose-fitting hood design provides high protection without the need for a tight-fitting face piece, which means:
      • Many wearers feel less constricted
      • Can be used by wearers with facial hair
      • Training needs are reduced
      • Face-fit testing is not required
  • The clear wide-view visor provides reassurance to casualties and victims by allowing easier, friendly ‘whole-face’ communication
  • The total weight of the PRPS suit with respirator is much less than a gas-tight suit with SCBA, less body contact (belt-mount versus shoulder-harness / tight-fitting face piece), and easier breathing results in a lower physiological load
  • Improved operational duration over gas-tight SCBA suits
  • Up to six times the resource efficiency compared with gas-tight SCBA suits thanks to the lower physiological loading and increased duration
  • Uncontaminated or ‘decontamination-guaranteed’ suits can be re-used following gas-tight re-test and re-certification


  • Reusable PVC training suit - PRPS(T)
  • Primary (single-use) lithium battery for Immediate operational use, and rechargeable battery for training use
  • Optional rehydration system and hard-hat
  • Choice of lightweight dexterity gloves for medical tasks or heavy-duty gloves for increased physical protection
