Hydrogen gas isextremely flammable and explosive.

To prevent the possibility of injury under these con-

opened for several minutes at the kitchen sink

before any electrical appliances which are connected

to the hot water system are used (such as a dish-

washer or washing machine). If hydrogen gas is pre-
