Figure 1-5. A chlorine gas cylinder.
(1) Safety plugs. These containers have fusible plugs that will melt at
160F; they should be stored under cover in areas away from excessive heat. They
should be separated by a wall from heaters such as pool heaters.
(2) Below ground storage. Since chlorine gas is heavier than air, chlorine
should not be stored or used below ground level.
(3) Tank in us. The chlorine tank or cylinder in use must be firmly held in
an upright position in a recessed sump, wall hung strap, or similar device. This is done
to prevent it from being knocked over and releasing chlorine gas.
(4) Tanks in storage. Full or empty cylinders in storage must be similarly
held in an upright position with the protective cap in place.
b. Transporting Cylinders. Cylinders should never be moved or stored unless
the protective cap is in place.
