SAFETY IN THE PLANT
Expert guidance is key when selecting fl ameless venting devices
Mistakes in fl ameless explosion protection can lead to danger and damage, explains Tomáš Wyka
T
he fi rst thing to know is that fl ameless venting is not regular explosion venting. Explosion venting is a favourite method in
the explosion protection market. Why? Its function is simple, eff ective and it’s easy to install and replace. A pressure- sensitive membrane installed on protected technology opens in the event of an explosion. Flame, heat and pressure are released outside to the safety zone and technology is protected. So, what exactly is fl ameless venting? Flameless explosion venting is a safety measure used in industrial settings to mitigate the risks associated with dust explosions. It involves the controlled release of pressure, fl ame, and heat from an explosion without allowing fl ames or burning materials to escape and cause secondary fi res or further damage. Flameless devices are used to facilitate
controlled explosion venting in scenarios where the presence of fl ames and the force generated during explosion venting could pose risks to personnel and infrastructure. T e diff erence between traditional explosion venting and fl ameless venting is one extra part. T e venting panel is

equipped with a fl ame-quenching device to avoid transmitting fl ames into the surroundings. So, will I get a fl ameless venting device if I add a fl ame-quenching element to my existing explosion venting device? T e answer is resolutely no.
TWO SEPARATE DEVICES Explosion venting devices and fl ameless explosion venting devices are two separate protection devices with specifi c norms, regulations and certifi cation. European norm EN 16009 recognises several fl ame- quenching elements, such as ribbon, parallel plates, ceramic or mesh/gauze type. T e mesh or gauze fl ame quenching element is one of the most used safety devices in various applications to prevent fl ame and heat transmission. It consists of multiple layers of mesh material with varying wire diameter and mesh size. When a defl agration (rapid combustion) event occurs in an enclosed space, pressure and heat build up. T e venting device releases this pressure and
