Pantograph arcing in electrified railways

We specialize in making flame resistant (FR) clothing. Our FR clothing are designed to protect workers/employees in most fire hazardous industries. Such hazards could include sparks and hot particles, molten metal splashes, electrical arc flash, flash fire, direct flame, radiant heat, solvents, acids, alkalis, oil and other hazardous substances.

Please contact us if you want to have your FR clothing tailored. Get an Estimate
