Danger Explosive Atmosphere ATEX Category 2 Sign questions answered
What does an ATEX Category 2 explosive atmosphere sign mean? It tells people that flammable material may be present during normal operation, so entry, tools, maintenance and ignition sources must be controlled.
Where should you place this EX warning sign? Fit it before the hazard point, such as on doors, cabinets, plant room entrances, fuel handling areas or process access points.
Is this sign enough to control an explosive atmosphere risk? No. It supports communication, but you still need risk assessment, trained staff, suitable equipment, ventilation and site controls.
Which material should you choose? Use self-adhesive vinyl for smooth indoor surfaces. Choose rigid plastic where the sign needs more structure or separate fixing.
When is the larger 297 x 210 mm size better? Choose the larger size when people approach from a distance, through a workshop, along a corridor or near a busy plant access route.
