Foundry and smelter workers operate in challenging conditions – these workers are mostly exposed to two catastrophic hazards: intense radiant heat and molten metal splash. Exposure to radiant heat can cause heat exhaustion and severe burns even without direct contact, while a ‘red metal’ splash (liquid metal exceeding 1 000°C/ 1 832°F) can prove fatal if their PPE fails to perform. To mitigate these risks, the industry relies on the advanced engineering, and protection, of aluminised personal protective equipment (PPE).

Radiant Heat Reflection and Shedding

The primary role of aluminised PPE is to act as a thermal mirror. Aluminised fabrics are designed to reflect up to 95% of radiant heat, significantly reducing the thermal load on the wearer. However, heat reflection is only part of what makes aluminised fabrics protective – when molten metal ‘splatter’ happens, the aluminised fabric must be able to ‘shed’ it.

In the event of a molten metal splash, the fabric must be able to allow the liquid metal to bead up and roll off instantly. If the metal adheres to the surface of the fabric, even for a second, the heat transfer is so intense that it will burn through the substrate. This is why specialised materials are utilised for high-quality aluminised gear. Unlike synthetic materials, these fibres do not melt or adhere to the skin when they come into contact with small volumes of molten metal for short periods.

The CHARNAUD® METAL-SAFE® ALPAN K Range

The CHARNAUD® METAL-SAFE® range is a range of hot metal protective wear offering a head-to-foot® solution for severe hot-metal applications. The ALPAN K series integrates aluminised materials with flame resistant (FR) thermal liners to manage both external heat and comfort of the wearer.

The CHARNAUD® METAL-SAFE® ALPAN K Aluminised Hood provides critical head protection. It features a fixed gold-on-green visor with a stainless-steel guard which is designed to reflect radiant heat away from the face while maintaining wearer visibility. For extreme conditions, these hoods can even be fitted with motorised ventilation fans to manage the ventilation inside the gear.

The CHARNAUD® METAL-SAFE® ALPAN K Aluminised Coat is available in 2 lengths – 125cm and 145cm – to ensure maximum coverage and protection for the wearer. It is designed with back breather vents and under-arm gussets to facilitate movement and airflow, while expansion pleats allow for the physical demands of furnace work.

The CHARNAUD® METAL-SAFE® range offers comprehensive protection through a variety of garments including smelter or hot metal boots, hand protection and gloves, hoods and visors and aluminised coats, jackets and trousers. The METAL-SAFE® ALPAN K Aluminised Trouser features adjustable webbing braces and a gusseted waist for a secure, ergonomic fit. Like the METAL-SAFE® ALPAN K Aluminised Coat, they are fully lined with FR thermal material to ensure that even if the exterior reaches extreme temperatures, the wearer remains protected.

Advanced Protection for Extreme Environments

In the world of molten metal work, specialised PPE is the only barrier against the risks of the job. Meticulously engineered for superior shedding ability and radiant reflection, the CHARNAUD® METAL-SAFE® range ensures that workers can face the heat of the job with confidence.
