Your next supplier of heat, flame & welding protective clothing

Protective workwear designed for environments where exposure to heat, flames, welding spatter and molten metal presents a risk. With nearly 100 years of expertise, we combine certified protection with comfort and freedom of movement to help keep industrial teams protected throughout their working day.

Understanding heat, flame and welding hazards

Not every working environment requires the same level of protection. Identifying the hazards your employees face is essential when selecting appropriate PPE.

Heat and flame exposure
Industrial maintenance, chemical processing and manufacturing may involve brief flame contact, radiant heat or convective heat. Clothing should be selected according to the level and duration of exposure identified in the risk assessment.

Welding and related processes
Welding, cutting and fabrication can expose workers to sparks, small molten metal splashes and radiant heat from the welding arc. Protective garments should be suited to the welding process, working position and expected exposure.

Molten metal and high-temperature environments
Foundries, steel production and metal processing can present risks from molten metal splashes and intense heat. The type of metal and potential exposure determine which additional performance levels are required.

Flame-retardant protective clothing

From flame-retardant coveralls and jackets to trousers and specialist welding garments, we offer protective clothing solutions for a range of industrial activities. Our focus goes beyond meeting technical standards. We consider how garments perform during everyday work, including freedom of movementand compatibility with industrial laundering processes.

Welding protective clothing

Which EN ISO standards apply to heat,
flame and welding protection?

Understanding the relevant European standards is essential when selecting protective clothing. Two key standards are EN ISO 11612 for heat and flame protection and EN ISO 11611 for welding and related processes.

EN ISO 11612 – Protective clothing against heat and flame

EN ISO 11612:2015 specifies performance requirements for protective clothing designed to protect against heat and flame hazards. Depending on its tested performance, a garment can provide protection against different types of thermal exposure.

Metal Sparks Flying – Sparks flying from metal cutting or welding process.

Additional standards for workplaces with multiple hazards

Depending on the environment, protective clothing may also need to comply with additional standards, including EN 1149-5 for electrostatic properties, EN 13034 for limited protection against liquid chemicals, or IEC 61482-2 for thermal protection against electrical arcs.The combination of standards required should always be determined by the specific workplace risks and verified against the certification of the selected garment.

EN ISO 11611 – Protective clothing for welding and allied processes

EN ISO 11611 defines requirements for protective clothing worn during welding and related processes. It addresses hazards such as small molten metal splashes, brief flame contact and radiant heat from welding arcs.

Two protection classes help distinguish between different levels of welding exposure.

  • Class 1: For less hazardous welding techniques and situations involving lower levels of spatter and radiant heat.
  • Class 2: For more hazardous welding techniques and situations involving greater exposure to spatter and radiant heat.

Frequently asked questions

Heat and flame protective clothing is assessed under EN ISO 11612, while welding PPE is assessed under EN ISO 11611. Welding protection covers additional hazards, including welding spatter and radiant heat from welding arcs. Some garments meet both standards.

No. Garments certified to EN ISO 11612 are not automatically suitable for welding. Clothing used for welding should meet EN ISO 11611 at the appropriate protection class.

This depends on the welding technique, expected spatter, radiant heat and working conditions. Class 1 applies to less hazardous welding situations, while Class 2 provides a higher level of protection for more demanding activities.

Yes. Certain garments combine heat and flame protection with welding, electrostatic, chemical splash or electrical arc protection. Always check the certifications of the selected garment.

Our flame-retardant garments are suitable for industrial laundering. Washing conditions and permitted cleaning cycles depend on the fabric and garment specifications. Following the manufacturer's care instructions is essential to maintaining protective performance.
