One of the most important advantages of Angle Guard Fire Extinguisher Cube is that it self-activates in presence of fire, even if no one is there. If placed in high fire risk areas, where most of fires break out, it will self-activate when reaching the flame and will instantaneously put out the fire. The best option for passive use of the Cube is to place it on a wall stand in the most high fire risk areas. The cube can be either placed on wall stand or simply put on a flat, visible, easy accessible surface. The most recommended areas are high risk fire areas such as electric cabinets or power switches, chargers, fireplaces, engine rooms, motor homes, caravans, horse transports, in stables, etc.
