Heat build up in PPE is a major problem especially working in a tropical environment. My idea is to cool a PPE using a water vest and a therml resevoire outside a PPE. The water vest will discharge body heat into the thermal resevoire with minimal modification to the PPE.
  • Works with most PPE with minimal modification
  • This vest can use water or ice inside the resevoire
  • Refill is safe and takes less than 1 minute
  • Will keep users cool for 15 minutes or more per refill
  • Can be prototype quickly and deploy rapidly
  • Will work with existing PAPR technology
  • Will work with positive pressure suit technology
  • Easy to clean and decontaminate
