Question

what precautions will you take to see that drinking water kept at public places is not contaminated ?​

Answer 1

Answer:

Explanation:

Boil water for one minute at a rolling boil or you may wish to use commercially bottled water.

Cooking foods at normal cooking temperatures will make the water safe. When washing off fruits and vegetables, making ice cubes, coffee in a percolator or other food processes that use water, be sure to boil the water first and cool it or use bottled water.

Bathing in this water is safe as long as you do not drink the water. Babies and small children should be supervised during a bath, do not let your child put water or a wet wash cloth in their mouths. You may wish to sponge-bathe your child with safe water.

Brushing your teeth/dentures should be done with safe water.

If your dishwasher has a hot/sani-cycle then it can be used, as it safely disinfects dishes. If it does not have this setting, after the final cycle, soak dishes for 1 minute in a solution of 30ml (1oz) of bleach mixed with 13.5 litres (3 gallons) of lukewarm water. Let dishes air dry.
