EXPLOSION PROTECTION
In industry, aspiration is associated with the movement of air or gas through ventilation systems to remove contaminants such as dust and fumes. Flammable gases, liquids, and fine particles increase the risk of explosions at certain concentrations. Sparks or flames can trigger hazardous explosions.
Explosions are more common in sectors where flammable materials are processed, particularly in the chemical, food, and metallurgy industries. To reduce risks, explosion protection systems are employed to vent pressure and dust, ensuring the safety of personnel and equipment.
What is a Dust Explosion and What is an Explosion Protection System?
A dust explosion occurs when a spark ignites combustible dust or fuel, leading to instantaneous combustion. This phenomenon creates a massive cloud of gas or dust that is released into the surrounding environment. It is important to note that an open flame is not required for an explosion to occur; various ignition sources can trigger this hazardous situation. When the internal pressure within a container becomes too high, it can result in an explosion.
Explosion protection is one of the most common and effective methods of ensuring safety in industry. It reduces the excessive pressure that arises during an explosion and creates a controlled path for the escape of expanding gases.
It helps limit the excessive pressure generated during an explosion by releasing unburned fuel mixtures and combustion products.
Ventilation panels do not prevent explosions; they assist in managing and controlling the maximum pressure within a vessel.
These panels function as essential pressure relief valves, directing the energy of the explosion outside the container.
Explosion protection systems are designed to fail at a predetermined pressure, ensuring safety and minimizing damage.
The VIGILEX ventilation valves, developed by STIF, meet all necessary health and safety standards, ensuring their suitability for use in environments with explosive atmospheric conditions (Directive 94/9/EC). These systems provide reliable protection and effective ventilation, making them ideal for application in industries where there is a risk of explosions.
