Working safely, even in high heat: how to protect yourself properly on the construction site?

What work clothes can limit heat stress?

On the construction site, technical clothing They play a direct role in thermal regulation. Loose, breathable clothing facilitates air circulation and reduces heat buildup on the skin.

The materials to thermal regulation They allow perspiration to escape to the outside. This principle, similar to so-called "breathable" textiles, limits the risk of overheating and improves comfort during prolonged exertion.

Color also influences thermal performance:

• light colors reflect solar radiation;
• dark fabrics offer a better UV barrierbut retain more heat.

In practice, teams often favour a compromise between sun protection and thermal comfort depending on the intensity of exposure.

"As a general rule, covering the skin remains the most effective protection against intense sun exposure."

An operational limit to be taken into account

Wearing long sleeves, recommended to limit UV exposure, can however accentuate the feeling of warmth In cases of high humidity or intense exertion, the choice of fabric becomes crucial to avoid excessive discomfort.

Shorts on construction sites and occupational risk prevention

Wearing shorts on construction sites remains a recurring issue during the summer months. While it improves the feeling of coolness, it directly exposes the skin to several risks:

• UV radiation and sunburn,
• material projections
• cuts caused by edges or tools,
• contact with abrasive surfaces.

As part of theRisk Assessment (single document – ​​DUERP), many companies maintain the obligation of long trousers, in accordance with safety requirements.

Alternatives exist with lightweight trousers incorporating:

• abrasion-resistant fibers,
• ventilation zones,
• an ergonomic design adapted to working postures.

Concrete example of application

On a major construction site, teams prefer breathable technical trousers because:

• to maintain mechanical protection,
• to limit work stoppages due to superficial injuries,
• maintain stable productivity despite the heat.

Personal protective equipment for the body on summer construction sites

Protection is not limited to clothing. The entire range of personal protective equipment (PPE) must be adapted to climatic conditions.

Head and face protection

Wearing a helmet remains mandatory on many construction sites. During the summer months, some models include:

• ventilation systems,
• absorbent fillings,
• UV-protective accessories.

When the risks allow, a protective cap can complement the device.

Breathable safety gloves and shoes

Gloves remain essential depending on the tasks performed. Breathable models allow you to:

• limit perspiration,
• maintain dexterity,
• reduce the risk of slipping.

Safety shoes are also evolving with materials that promote air circulationThis limits internal heating and improves comfort over long days.

"The wearing of protective equipment remains dictated by the risks of the worksite, regardless of the temperature."

Skin protection and sun exposure

Skin protection complements PPE. The application of a high-SPF sunscreen (minimum SPF 30, SPF 50 in intense exposure) is recommended.

Renewal must be regular, in particular:

• after perspiring,
• after rubbing of the clothes,
• during prolonged exposure.

Work organization and regulatory framework

Beyond equipment, site organization is a key factor. Labor Code requires the employer to take the necessary measures to ensure the safety and protect the physical health of the teams.

This includes :

• adjusting schedules in case of extreme heat,
• the provision of drinking water,
• the creation of shaded or rest areas,
• raising awareness of the risks associated with heat.

The recommendations of theINRS (National Institute for Research and Safety) also emphasize the prevention of heatstroke, major risk on exposed construction sites.

Field data

For some summer operations, companies adjust the time slots as early as 6 or 7 a.m. to limit exposure to the afternoon heat peaks.

Uniform management and textile logistics

Managing workwear is an organizational challenge. Outsourced solutions enable:

• to ensure the regular maintenance of textiles,
• to maintain a satisfactory level of hygiene,
• to guarantee the availability of PPE adapted to each season.

This type of organization reduces internal constraints, particularly in terms of equipment storage and tracking.

A nuance to consider

These devices involve a logistical dependency and require rigorous planning. In the event of rapidly changing climatic conditions, adapting supplies may take time.

"Companies are equipping their teams with coordinated and centralized solutions."

Adapting practices to secure the structures

Working in extreme heat is not just a matter of comfort. It is a matter of overall site safety and quality of implementation.

Staff exposed to heat may see:

• his vigilance decreases.
• its accuracy will degrade,
• the risk of accidents increases.

Adapting equipment, combined with appropriate organization and active prevention, makes it possible to maintain the conditions necessary for carrying out the works in good conditions.

In this context, the management of PPE, the choice of textiles and the anticipation of climatic conditions are essential operational levers for construction companies.
