Chicago Protective Apparel 6000-ACK Aluminized Carbon Para-Aramid Approach

A WORD OF CAUTION: DO NOT CONFUSE AMBIENT, CONDUCTIVE AND RADIANT HEAT! The following definitions are given as a reference as well as vital assistance in selecting the proper clothing for heat protection:

 

Ambient Heat is the surrounding atmospheric temperature in a given situation. Examples: 65º-70ºF in an office; 2000ºF in a fire walk.

 Conductive Heat is generated by direct contact with a hot surface. Examples: picking up a burner block at 600ºF; leaning against a furnace wall at 1000ºF. 

Radiant Heat is generated by the sun or a source of fire, such as a fireplace or furnace, and is absorbed by masses of material struck by the heat’s rays. (This is why it is cooler in the shade on a hot day.) 

Primary Protective Clothing Data Protective clothing designed to be worn for work activities during which significant exposure to molten substance splash, radiant heat, and flame is likely to occur. Such work activities include charging, taping, and pouring, during which work is carried out in close proximity to molten substances and hot surfaces and contact with either is likely.

 Secondary Protective Clothing Data Protective clothing designed for continuous wear for work activities in designated locations in which intermittent exposure to molten substance splash, radiant heat, and flame sources is possible. Secondary protective clothing is designed so that it will not continue to burn after exposure to and removal of a source of ignition. Protection against metal splash and radiant heat are secondary in intent.
