MOLTEN METAL
Protection Clothing
The Hazard
Molten metal splash is caused by accidental contact of moisture or any liquid bearing material to the hot melt deck. This produces a violent explosion and throws molten metal and high-temperature solids out of the bath, putting workers and nearby plant and equipment at risk.
The violent and unpredictable nature of a molten metal explosion makes the wearing of appropriate Personal Protective Equipment (PPE) imperative, which can help prevent serious injuries and fatal burns.
- Tarasafe offers a range of FR protective clothing for both Molten Iron and Molten Aluminium Splash protection.
- The protection level ranges from E1 to E3 and D1 to D3.
The risk hazards of Molten Metal, both for Iron & Aluminium splash can be assessed on the PPE as per EN ISO 11612 norm, which covers protection against accidental flame & various Heat hazards like Convective, Radiant and Contact Heat.
Suggested Norms
EN ISO 11611: 2007
Protective clothing for use in welding and allied processes.
Protection against welding and allied processes
Protective clothing certified according to EN ISO 11611 gives the wearer protection against small splashes of molten metal, brief contact with flame & radiant heat. The garments certified to this standard are suitable for use in welding and allied processes.
The garment is classified for the protection ability against different levels of welding technology, which cause more or less spatter and radiant heat :
- Class I - Protects against less hazardous welding techniques and situations, causing lower spatter and radiant heat. Tested with 15 molten metal drops.
- Class II - Protects against riskier welding techniques and situations, which causes higher levels of spatter and radiant heat. Tested with 25 molten metal drops.
- The protection level covers both Class I and Class II.
Also procedure A1 / A2 must be tested for ISO 15025 for flame spread.
EN ISO 11612: 2008
Protection against Heat & Flame
Protection against Heat & Flame
Protective clothing certified according to EN ISO 11612 gives the wearer protection against brief contact with heat and flame. The heat can be convective, radiant, molten material, or a combination thereof.
The garment is classified for the following parameters:
- (A1) Limited flame spread - Surface Ignition
- (A2) Limited flame spread - Edge ignition
- (B) Convective heat
- (C) Radiant heat
- (D) Molten aluminum splash
- (E) Molten iron splash
- (F) Contact Heat
