Over time, sunlight and evaporation cause the chlorine and other chemicals in pool water to lose their effectiveness. Chemicals that are designed to disinfect swimming pools have chlorine concentrations ranging from approximately 12 to 95%. The concentration must be high because the chemicals are designed to be diluted in water.
The amount of chlorine you need to add to a swimming pool is greater than the amount you need to add to regular drinking water to disinfectant it. Because not only is there contamination of the water from many sources but these chemicals also become less effective with time due to evaporation and exposure to the sun. In addition, over time sunlight and evaporation …show more content…
And why?
Swimming pool chemicals include various kinds of disinfectants and sanitizers which work to control the growth of certain kinds of algae and bacteria in the pool water. Swimming pool chemicals may also be used in hot tubs, spas, wading pools, and whirlpools.
Various kinds of disinfectants and sanitizers are used but the "chlorine" type is the most common. The chlorine usually comes from "chlorinating agents" that release chlorine when they are dissolved in the water. Chlorine gas may be used in large pools.
The chlorine-based disinfectants may be called "chlorinating liquid", "dry chlorine" or "liquid chlorine". The so-called "dry chlorine" is actually chemicals in granular or tablet form while "liquid chlorine" and "chlorinating liquid" are solutions of these chemicals dissolved in water. This document will summarize the safe use of these chlorinating agents but it will not discuss the use of chlorine gas.
Oxidizing materials (such as calcium hypochlorite) have the ability to react chemically to oxidize combustible (burnable) materials. To be an "oxidizer", the material itself provides oxygen which combines chemically with another material in a way that increases the chance of a fire or explosion. This reaction may be spontaneous at either room temperature or may occur with slight …show more content…
Corrosives are materials that can attack and chemically destroy body tissues on contact. Corrosives can also damage or destroy metal. The effects on tissues and metals depends on what the corrosive agent is and how concentrated it is. They can begin to cau
Safety ethics and environmental implications
• Read and follow instructions carefully
• Keep all chemicals out of the reach of children and pets.
• Containers should always be kept closed when not in use.
• Use separate, clean metal or plastic measuring cups for each chemical to transfer or measure chemicals. (Scoops should not be made of wood.)
• Wear appropriate protective equipment and clothing including goggles, gloves and footwear.
• Protect chemicals from moisture and water - such as a cup of water (or coffee!). Even putting the wet scoop back into the pail may cause a reaction.
• Always add the chemical to the pool water - never the other way around (never add water to the chemical) unless instructed to do so on the container label.
• Wash your hands thoroughly after handling any chemicals.
• Use or handle chemicals in well ventilated areas only.
