Allow people to drink according to their needs
Many people need even more than the average of one gallon per day. The individual amount needed depends on age, physical activity, physical condition and time of year.
Never ration drinking water unless ordered to do so by authorities.
Drink the amount you need today and try to find more for tomorrow. Under no circumstances should a person drink less than one quart (four cups) of water each day. You can minimize the amount of water your body needs by reducing activity and staying cool.
Drink water that you know is not contaminated first.
If necessary, suspicious water, such as cloudy water from regular faucets or water from streams or ponds, can be used after it has been treated. If water treatment is not possible, put off drinking suspicious water as long as possible, but do not become dehydrated.
Do not drink carbonated beverages instead of drinking water.
Carbonated beverages do not meet drinking-water requirements. Caffeinated drinks and alcohol dehydrate the body, which increases the need for drinking water.
Turn off the main water valves.
You will need to protect the water sources already in your home from contamination if you hear reports of broken water or sewage lines or if local officials advise you of a problem. To close the incoming water source, locate the incoming valve and turn it to the closed position. Be sure you and your family members know how to perform this important procedure.
Safe Sources
Melted ice cubes.
Liquids from canned goods such as fruit or vegetables.
Water drained from pipes. To use the water in your pipes, let air into the plumbing by turning on the faucet in your home at the highest level. A small amount of water will trickle out. Then obtain water from the lowest faucet in the home.
Water drained from the water heater. To use water in your hot-water tank, be sure the electricity or gas is off and open the drain at the bottom of the tank. Start the water flowing by turning off the water intake valve at the tank and turning on the hot-water faucet. After you are notified that clean water has been restored, you will need to refill the tank before turning the gas or electricity back on. If the gas is turned off, a professional will be needed to turn it back on.
Unsafe Sources
Radiators Hot water boilers (home heating systems).
Water from the toilet bowl or flush tank.
Water beds. Fungicides added to the water or chemicals in the vinyl may make water unsafe to use.
Swimming pools and spas. Chemicals used to kill germs are too concentrated for safe drinking but can be used for personal hygiene, cleaning and related uses.更多精彩文章及讨论，请光临枫下论坛 rolia.net
