40、al information on chlorine A.1 Origin A.1.1 Raw materials Chlorine is manufactured from a sodium chloride solution. A.1.2 Manufacturing process Electrolysis of alkaline metal chlorides (generally in the form of a solution). A.2 Use A.2.1 Function Disinfectant, oxidizing polluting matter introduced t
41、o the pool water by bathers. A.2.2 Form in which the product is used It is used as delivered (see A.2.4) A.2.3 Treatment dose The treatment dose depends on the composition of swimming pool water, subject to national regulations and depending on the required free chlorine concentration in the swimmin
42、g pool water. A.2.4 Means of application Only vacuum chlorinators should be used and a separate chlorine-gas room having special fittings will always have to be provided for safety reasons. An automatic chlorine cylinder switchover system should be provided to prevent any interruption in the chlorin
43、ation (in particular due to chlorine cylinders becoming empty). As a result of adding chlorine gas, hydrochloric acid is formed in the water and the resulting acidity causes a drop in the pH value. To avoid any undesirable drop in this value if the acidity is low, the chlorine solution may be fed th
44、rough a reaction vessel filled with calcium carbonate (e.g. high-purity marble or Jurassic limestone). A.2.5 Secondary effects The secondary effects include the following: decrease in pH due to generation of hydrochloric acid; formation of chloramines (combined chlorine) and organo-chlorinated by-pr
45、oducts such as trihalomethanes, depending on swimming pool water quality.

46、ducing agent such as an aqueous solution of a sulfite compound. Other methods use activated carbon or hydrogen peroxide.

47、rules relating to safety B.1 Rules for safe handling and use The supplier shall provide current safety instructions. B.2 Emergency procedures B.2.1 General To ensure that chlorine is handled safely, all manufacturers of chlorine possess an emergency instructions file which includes safety. WARNING:
48、The user should request the safety instructions from the supplier and read them before using chlorine. The user will inform the local health authorities and fire brigade of its storage capacities. The following information is only a very brief summary of actions to be taken in case of emergency. B.2
49、.2 First aid In case of contact with skin, wash immediately with plenty of water. Seek medical advice. In case of inhalation of gas, allow the victim to rest in fresh air. Other medical care can be necessary. Seek medical attention immediately. B.2.3 Spillage Put on breathing apparatus. Isolate contaminated area by means of water curtains. Call local fire brigade. B.2.4 Fire Chlorine is not flammable. Storage cylinders or chlorine containing pipes can burst when exposed to a fire, causing toxic emanations. Licensed Copy: London South B
