ABSTRACT:
A protective device for protecting a person's body from heat and gas, comprises a body suit which covers the person's body and which has a refrigerant storage tank connected to the back of the suit for storing a solid refrigerant, such as dry ice. The refrigerant, or a liquid produced from the refrigerant, is circulated from the tank around the suit for cooling the suit and the wearer. The apparatus includes an indicator having a display portion located in the field of vision of the wearer and connected back to the tank for indicating the condition of the refrigerant, such as, the total amount of solid refrigerant left, whether the melted refrigerant is leaking from the system and/or any other condition concerning the cooling system to the wearer.
