METALSTAR – Molten Metal Splash Protection


The process of combining metals with pressure, heat, flame or electric arc is called welding. Welding work is a safe occupation if adequate measures are taken against potential hazards. If these measures are ignored, welders may be exposed to sparks, molten metal splashes,radiation, heat, hot metal, smoke, gas and even electric shock.

Welders should wear a garment that protects them from injury, such as firemen or many other occupational groups. The most common of all injuries is burns which are formed by bare spattering of sparks. Severe burns occur when the very intense arc of contact touches the skin for a short period of time.

Molten metal splash like in an iron & steel company may be very dangerous. Molten metal may stick on the outer fabric of the workwear and burn the skin of the person which may held to severe injuries. Traditional fabrics like cotton or polyester start burning, melting or dripping during welding or molten metal splashes which increases the body burn.

METALSTAR Protective Clothing provides permanent flame resistance; does not melt, ignite and continue burning; insulates the wearer from heat and decreased/avoid heat burns; provide time to escape; increases the chance of survival.

Application Areas

Main application areas are classified as Iron & Steel Industry, Automotive Industry, Engineering Projects, Foundries, Railways, Shipbuilding and Welding.

ISO 11612 Heat & Flame Protection:

The purpose of this standard is to provide minimum performance requirements for clothing to protect against heat and flame. Within many of hazards listed in this standard there are three performance levels (except Radiant Heat where there are 4 Levels). Level 1 indicates exposure to perceived low risk, Level 2 indicates exposure to perceived medium risk and Level 3 indicates exposure to perceived high risk.

  • Code A: Limited Flame Spread (A1, A2)
  • Code B: Convective Heat (B1, B2, B3)
  • Code C: Radiant Heat (C1, C2, C3, C4)
  • Code D: Molten Aluminum (D1, D2, D3)
  • Code E: Molten Iron (E1, E2, E3)
  • Code F: Contact Heat (F1, F2, F3)

ISO 11611 Heat & Flame Protection:

ISO 11611 specifies minimum basic safety requirements and test methods for protective clothing including hoods, aprons, sleeves and gaiters that are designed to protect the wearer’s body including head (hoods) and feet (gaiters) and that are to be worn during welding and allied processes with comparable risks.

ISO 11611 specifies two classes with specific performance requirements, i.e. Class 1 being the lower level and Class 2 the higher level.

Class 1 is protection against less hazardous welding techniques and situations, causing lower levels of spatter and radiant heat.
Class 2 is protection against more hazardous welding techniques and situations, causing higher levels of spatter and radiant heat.
