HEAT AND FLAMES WHAT’S THE RISK?
INJURIES BURNS INJURIES CAN RANGE FROM MILD TO SEVERE AND THEY CAN EVEN BE FATAL.
Heat exposure can occur through either; direct contact (conduction), liquids and gas including air(convection) or through electromagnetic waves (radiation). Flame risk is caused from exposure to the stream of hot, burning gas from something on fire (flames). Accidental splattering or spraying of moltenmetal is also a workplace risk factor.
WHO IS AT RISK? Workers in industries including: electrical utilities, petrochemical, transportation road and rail, metalworking, foundries, cement works and craftspeople (except welders and firefighters).

EN ISO 11612: 2015 protective clothing where there is a need for clothing with limited flame spread properties. THE TEST You must pass either A1 or A2 tests AND one other from B, C, D, E or F
EN ISO 14116 protective clothing to protect against occasional and brief contact with small igniting flames reducing the possibility of the clothing burning and thereby itself constituting a hazard. THE TEST Three different categories for flame spread, Index 1, 2 and 3 as detailed across:

INJURIES BURNS FROM FIRE, SPARKS, OR FLAMMABLE MATERIAL, INFRARED RADIATION EXPOSURE AND ELECTROCUTION.
WELDING WHAT’S THE RISK?
The sparks and expulsion of molten metal produced by welding and cutting processes are ready sources of ignition that can travel up to 35 feet (10 meters) from their source.
WHO IS AT RISK? Those working in welding and allied processes.
Class 1 -less hazardous welding techniques and situations causing lower levels of spatter and radiant heat. Class 2 -more hazardous welding techniques and situations causing higher levels of spatter and radiant heat.
