Cylinder and Ton Container Storage
Whether in storage or in use, cylinders
should not be permitted to stand unsupported. They should be chained to a fixed wall
or support, and in such a manner as to permit ready access and removal. Ton containers
should be stored horizontally, slightly elevated from ground or floor level, and blocked
to prevent rolling. A convenient storage rack is obtained by supporting both ends of
containers on rails of I-beams. Ton containers should not be stacked or racked more
than one high unless special provision is made for easy access and removal. Chlorine
cylinders and containers should be protected from impact, and handling should be kept
to a minimum. Full and empty cylinders and ton containers should be stored separately.
Figure 24-5 illustrates chlorine storage and handling for ton containers.
