'''Area of use''': Wherever drinking-water needs to be disinfected and chlorine is available.
==Construction, operations or and maintenance==
The flow rate of the raw water must be checked and adjusted if necessary, and the chlorine tank must be refilled with a freshly-prepared solution once or twice a week. Operators must be careful to avoid contact with chlorine compounds or solutions, and use protective gloves and utensils to prepare the chlorine solutions. The gloves and utensils will need to be replaced occasionally. In some cases, the amount of chlorine added to the water, together with residual chlorine levels, are recorded in a logbook. Chlorinators must be adjusted and cleaned of chlorine salts regularly, and when the hoses become corroded by chlorine they must be replaced.
