Hydrogen gas is extremely flammable and explosive.
To prevent the possibility of injury under these con-
ditions, we recommend the hot water faucet be
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-
sent, there will probably be an unusual sound stmi-
lar to air escaping through the pipe as the hot water
faucet is opened. There must be no smoking or open
flame near the faucet at the time it is open.
