Both full and empty cylinders should always be stored upright and secured with a chain to prevent them from tipping over. 34 WATER CHLORINATION/CHLORAMINATION PRACTICES AND PRINCIPLES Ton Containers The ton container is a reusable, welded tank that holds 2,000 lb (910 kg) of chlorine. Containers weigh about 3,700 lb (1,700 kg) when full and are generally 30 in. 76 m) in diameter and 80 in. 03 m) long. As shown in Figure 4-2, the ends are concave. The container is crimped around the perimeter of the ends, forming good gripping edges for the hoists used to lift and move them.

Lead gaskets are recommended at frequently changed connections to provide a good seal with a material that has more desirable physical characteristics. These gaskets must be replaced each time the connection is opened. The life of a flexible connector, sometimes called a pigtail, can be extended by using isolating valves at locations where frequent connection changes are made. Isolating valves protect the open end of the flexible connector from moisture intrusion during the change. The frequency of container changes and moisture content of the chlorine gas affects the life of the flexible connector.
