Explosive atmosphere in the collection tank

Sewage containing faeces can lead to gas collections in the tank. These gas collections can come out into the operating space because of incorrect installation or maintenance work. An explosive atmosphere can occur. This atmosphere can ignite and lead to an explosion. To prevent an explosive atmosphere, follow these points:

• Only use undamaged tanks (no cracks, leaks, porous material). Switch off lifting units with damaged tanks immediately.
• Make sure that all connections for the inlet, discharge pipe, and ventilation are sealed tightly. Obey local regulations for these connections.
• Route the ventilation pipe.
• For floor-mounted or concealed-wall installation in buildings, route the ventilation pipe over the roof of the building. Obey the local regulations for the correct length of the pipe above the roof.
• For concealed-floor installation (underground installation) outside of buildings, route the ventilation pipe over the surface. Obey the local regulations for the correct length of the pipe above the surface.
• When opening the tank (e.g. during maintenance work), make sure that the operating space is sufficiently ventilated.
