Among the elements essential to the safety of an ATEX zone, thehorn plays a key role. An electronic or mechanical device designed to emit an audible signal, it can be used to alert your employees. But where to place these devices for optimum effectiveness?
I. Identify hazardous areas in your ATEX zone
Before placing your horns in your ATEX zone, you need to identify the zones at risk. These zones can be determined by several factors, including the type of activity carried out in the area.
For example, an area where flammable substances are regularly handled will have a higher risk of explosion. Similarly, an area where high-temperature machinery is used will also be at greater risk.
It’s important to note that even areas that appear safe at first glance can present hidden risks. An area that is often cleaned with flammable chemicals can also be a high-risk zone.
| Here are some examples of high-risk areas: – Chemical storage areas – Production areas where high-temperature machines are used – Cleaning areas where flammable products are used |
Once you’ve identified the areas at risk, you can start planning where to place your horns. It’s also essential to consider where to place them, depending on whether they are electrically triggered or require a manual release. Each horn should be positioned so as to be clearly audible throughout the hazard zone.
II. Choosing the right horns for your environment
Once you know where to place your sound devices, turn to equipment adapted to your industrial environment. For ATEX-suitable devices, we advise you to consider several criteria:
- Volume: it must be high enough to overcome ambient noise.
- Resistance : humidity, temperature and dust are all elements that can be found on industrial sites. Your equipment must be adapted to environmental conditions. Robust, adapted equipment ensures superior longevity.
- Distance: this depends on the size of your ATEX zone. A device with a wider range will be needed for larger spaces.
- Ease of installation and maintenance: a system that’s easy to install and maintain will save you time and money.
Consider these criteria when making your choice. You’ll be ensuring the safety of everyone in your ATEX zone.
III. Determine strategic locations for your horns
In an ATEX zone, the location of your horns is crucial. They need to be positioned so that they can be heard everywhere. High-risk areas, such as confined spaces, are preferable.
Place ATEX sirens near entry and exit points. This will enable them to provide an effective warning in the event of a necessary evacuation. Avoid installing them near noisy machinery. The sound could be drowned out and the warning unnoticed.
And don’t forget to install them at ear level for better audibility. Remote or isolated locations should not be overlooked. All workers must be able to hear the horn, whatever their location.
The correct positioning of your audible warning devices in your ATEX zone is essential to guarantee everyone’s safety. Positioning must be carefully considered to ensure optimum sound diffusion and effective warning in the event of danger. Don’t forget that expert advice is always recommended to ensure that your installation complies with the relevant standards. Safety should never be taken lightly.
