when about 2/3 full or max 20 kg. Release the two fasten-
ers and remove the container. Be careful when releasing the
fasteners, as they can open with great force, especially when
the material is heavy. Be aware that emptying the container
may pose a risk of explosion, i.e. an explosive atmosphere
may occur and a static charge may be generated by the fric-
tion of particles against the container. See CENELEC TR
50404 for the appropriate measures.
When the container is attached back onto the dust extrac-
