ATEX er en forkortelse for den franske betegnelse ’atmosphére explosive’. Oversat til dansk betyder ATEX eksplosiv atmosfære. Eksplosive atmosfærer opstår som følge af forskellige arbejdsprocesser, fx bearbejdning af metal eller træ, hvor støv hvirvles op og blandes med luften.

Er Atex-ventilation lovpligtigt?

Da eksplosionsfarlige miljøer kan medføre personskade og store konsekvenser for en virksomhed eller organisationens maskiner og interiør, findes der to ATEX-direktiver, der regulerer, hvad man må og ikke må, når man arbejder i eksplosionsfarlige miljøer

ATEX ventilation provides safety in explosive environments

Does your company fully understand how to protect itself against ATEX (explosive atmospheres)? Or do you need guidance on how to best avoid sudden explosions?

ATEX is a complex area that can be difficult to navigate if you don't know how to handle it correctly. At the same time, ATEX should be high on the agenda for the majority of Danish manufacturing companies, as many companies unknowingly have potentially explosive atmospheres present in their production.

At Technor, we can help your company create workplace safety through effective and safe ATEX ventilation. We are experts in all forms of industrial ventilation, including the removal of explosive atmospheres, and we can help with the development, setup and servicing of ATEX ventilation systems.

What is ATEX?

ATEX is an abbreviation for the French term 'atmosphère explosive'. Translated into Danish, ATEX means explosive atmosphere. Explosive atmospheres arise as a result of various work processes, such as processing metal or wood, where dust is swirled up and mixed with the air. If a spark is lit near this mixture, it can ignite and start an explosion - to the danger of both employees, machines and buildings. Explosive atmospheres can also arise due to flammable gases and vapors.

For an explosion to occur, three things must be present – an ignition source, oxygen and a combustible substance. The explosion occurs very quickly if the three things are combined, so it is essential to ensure that the dust or gas is vented using an ATEX-approved ventilation system.

Ventilation industry form

Do you work in a potentially explosive environment?

Many industries and workplaces in Denmark are exposed to the danger of explosive atmospheres. If you work, for example, in a furniture factory or as a carpenter in a workshop, it is important to ensure that you minimize the ATEX danger by using correct ventilation. This not only provides security in everyday life - it also creates a good and healthy working environment, where you can stay for a long time without getting dizzy, getting headaches or feeling other discomfort due to the indoor climate.

You can protect yourself against explosions by conducting a risk assessment of the workplace and securing your business based on this.

ATEX ventilation is mandatory

Since explosive environments can cause personal injury and major consequences for a company or organization's machinery and interior, there are two ATEX directives that regulate what is allowed and not allowed when working in explosive environments (1992/92/EC) and when producing products related to ATEX (2014/34/EC). Both directives help to avoid sudden explosions.

At Technor, our ventilation systems comply with the relevant legislation. This is your assurance that you can use our systems with peace of mind without worrying that neither employees nor the interior are in danger.

Did you know that the following tasks (among others) are particularly vulnerable in relation to ATEX?

Production of wood products such as particleboard, furniture, windows, etc.
Grinding of certain metals such as aluminum etc.
Composite processing
Spray paint
Handling flammable gases and flammable liquids
Food processing

Workplace assessment?

In addition to the directives, an executive order (590 of 26 June 2003) has also been issued, which is aimed at employers in workplaces where there is an ATEX risk. According to the executive order, a company must prepare a workplace assessment (APV), which is an assessment of the risk associated with carrying out work in the company. In the context of ATEX, this is called an ATEX APV, which describes where and when there is a risk of an explosion as a result of working with various machines and processes.

An ATEX APV identifies, classifies and marks the potentially explosive areas in a company. This is done easily and clearly by dividing the workplace into different ATEX zones (see next section).

We use the ATEX APV to assess your ventilation needs so that we can put together a system that matches your needs perfectly.

ATEX zones

Hazardous areas can be divided into different zones – from very hazardous to less hazardous areas. An hazardous area can, for example, be a work process where metal is cut, and metal dust is generated as a result. For example, if a gas leak occurs in connection with the production of a product, that part of the production is designated as an hazardous area. An hazardous area can be both small and large.

The zones classify what can trigger an explosion, how often there is a risk that an explosion will occur, and which category the area belongs to. There are 6 ATEX zones:

Zone 0: Area where an explosive atmosphere consisting of a mixture of flammable substances in the form of gas, vapours or mists with air occurs continuously or for long periods or frequently.

Zone 1: Area in which an explosive atmosphere consisting of a mixture of flammable substances in the form of gas, vapours or mists with air can be expected to occur occasionally during normal operation.

Zone 2: Area where an explosive atmosphere consisting of a mixture of flammable substances in the form of gas, vapours or mists with air is not expected to occur during normal operation, or if this occurs, then only for short periods.

Zone 20: Area where an explosive atmosphere in the form of a cloud of combustible dust in air occurs continuously or for long periods or frequently.

Zone 21: Area where an explosive atmosphere in the form of a cloud of combustible dust in air can be expected to occur occasionally during normal operation.

Zone 22: Area where an explosive atmosphere in the form of a cloud of combustible dust in air is not expected to occur during normal operation, or where the occurrence, if it does occur, is only of short duration.

The division into ATEX zones can be used to ensure that the workplace meets the requirements of the ATEX directive, and it can also provide an overview of where to take action to reduce the risk of explosion.

Should we find a solution to your ATEX ventilation problem?

Is there a risk of explosion in your workplace, but do you find it difficult to navigate the ATEX field? At Technor, we have more than 25 years of experience in protecting employees and workplaces against explosive environments through approved ATEX ventilation systems. We are also happy to help your company develop and set up a fully integrated ventilation system, so you no longer have to worry about explosion hazards in the workplace.
