The sweat evaporation restriction of PPE ensembles and the increase of heat production from incident response and training exercises are the main factors of enhancing the heat strain on responders. Personal protection equipment has its limitations. Full protection suits become hot inside: Encapsulation and moisture-impermeable CPC material lead to heat stress. Responders find it difficult to wear suits for long periods of time. Wearing level A PPE for longer than 30 minutes is difficult.
In the particular instance of EOD PPE, the material specifications required to provide ballistic protection means that the suits provide a high level of insulation, impermeability and weight. An unintended consequence is the creation of a hostile microclimate for the wearer, which dramatically reduces the capacity for heat exchange with the ambient environment. Since the physical demands of work tasks raise metabolic heat production and the required protective clothing impairs heat loss, the risk for bomb technicians to experience excessive heat strain and/or heat illness is high.
All Cool technology yields effective large body surface area cooling below, approaching and exceeding the atmospheric dew point temperature (including within the water vapor saturated micro-environment of donned PPE).
All Cool technology increases both the action and the duration of the thermal gradient for cooling responder(s) and/or victim(s) to more than 3 hours in PPE.
All Cool garments are reusable, do not require refrigeration and have no expiry date.
