Quick Answer
Chlorine is commonly used in emergency shelters to disinfect water, making it safe for consumption, and is usually added in the form of tablets or drops, which contain a specific amount of chlorine, such as 2.7% available chlorine.
Proper Use of Chlorine in Emergency Shelters
When using chlorine drops in emergency shelters, it is essential to follow the recommended guidelines to ensure safe and effective water disinfection. The World Health Organization recommends adding 2-4 drops of 2.7% available chlorine per liter of water. This amount is enough to kill most pathogens, including bacteria, viruses, and protozoa.
Precautions and Safety Measures
Using chlorine in emergency shelters requires careful handling to prevent skin and eye irritation. It is crucial to handle chlorine tablets or drops with gloves and avoid touching the eyes or face after handling chlorine. Additionally, chlorine can react with food and other substances, causing unpleasant odors and tastes. To minimize these effects, it is recommended to let the disinfected water sit for at least 30 minutes before consumption to allow the chlorine to dissipate.
Maintaining Water Quality
Regularly testing water quality is vital in emergency shelters to ensure that the chlorine levels are within the safe range. The ideal chlorine level for drinking water is between 0.5 and 1.0 ppm (parts per million). If the chlorine level is too high, it can be unpleasant and even lead to health issues. To maintain water quality, it is essential to regularly test the water and adjust the chlorine levels accordingly. This can be done using chlorine test kits or water testing strips.
