Heat range: a complete protection adapted to all risks

Exposure to flames, handling tools or products at high temperatures, heat waves… the risk of heat does exist and sometimes makes workers’ tasks difficult.

This is why ROSTAING wanted to develop an anti-heat range o protect its users from all the risks associated with working in the heat.

What are the risks of heat exposure?

In theory, the regulations do not define what constitutes work in the heat.

It is commonly considered to be dangerous from 30°C for sedentary activities and 28°C for work involving physical activity.

Above 35°C, heat stress is considered intolerable for most workers.

How is heat work defined?

Working with heat involves at least one of these criteria:

  • The presence of molten materials such as metal or glass;
  • High-temperature machinery and tools;
  • A combination of heat and humidity;
  • Harsh weather or environmental conditions, such as heat waves or desert climate.

All of these situations can involve excessive heat levels.

What are the risks of working in the heat?

Mainly physical risks such as the risk of burns, but also heat-induced effects such as fatigue, sweating or headaches.

Exposure to heat – extreme or not – can also lead to dehydration or heat stroke. It can also lead to reduced alertness, latency and visual impairment. Thermal risk can also be synonymous with lethal risk under certain conditions. For this reason, there are references for so-called type III gloves (against fatal risks).

These effects result in a maximisation of accidents at work. 

Which jobs are affected by heat-related risks?

The main professions at risk are mainly in the construction, industry and agriculture sectors.

However, thermal stress can also apply to occupations such as food, transport or the craft industry.

What standards govern heat protection?

When assessing the risks in a workplace, a heat balance is drawn up, i.e:

  • The general thermal environment (temperature, humidity, etc);
  • The body heat production of the workers;
  • The thermal properties of PPE.

However, the state of health of the workers is also taken into consideration. Overall, the heat balance is mainly used to set up work practices designed to limit the risks for the personnel.

But there is no real standard for heat protection, only a standard for the design of heat resistant gloves.

EN 407 standard gloves are therefore designed to protect against thermal hazards such as:

  • Flames;
  • Contact heat;
  • Radiant heat; 
  • Convective heat;
  • Molten metal splashes.

EN 407 gloves have increased heat resistance, reduced temperature transmission, and a reduced flammability and fire spread rate compared to a conventional protective glove.

In addition, there are other standards that relate to EN 407 in terms of testing protocols, namely the firefighters’ standard EN659 and the welders’ standard EN 12477.

To protect your hands or those of your workers from the heat, ROSTAING has developed a complete range of heat-resistant gloves for different uses. Here is a selection of our heat-resistant technical gloves:

Heat range: a complete protection adapted to all risks

PROSOUD/1 model

The glove is designed for welding operations, but also for metal forming and stamping. It is resistant to contact heat up to 100°C and has a high resistance to molten metal splashes. It also protects against the risks of high cuts. Finally, the PROSOUD/1 glove is welder’s standard.

Heat range: a complete protection adapted to all risks

PARA4HEAT+ model

Very comfortable, this model is designed for the plastics, steel and glass industries. Designed to withstand high temperatures (up to 250°C) and cuts, it is also available in a short version without cuff.

Heat range: a complete protection adapted to all risks

PROTRI-1 model

Designed for the steel industry, foundries and blast furnaces, this glove is recommended for handling parts coming out of the furnace. The glove has a waterproof membrane, resists contact heat of 350°C and is highly resistant to cuts.

Heat range: a complete protection adapted to all risks


With the highest levels of performance in heat tests (EN407), the glove is recommended for operations in metallurgy, steelworks, foundries or forges. Designed to withstand the highest temperatures (up to 500°C), its aluminised back also gives it excellent resistance to liquid metal splashes!
