HYDROGEN GAS: Hydrogengascanbeproducedin a hot
water systemthat hasnot been usedfor a long period of
time (generally two weeks or more). Hydrogen gas is
extremely flammable and explosive. To prevent the possi-
bility of injury under these conditions,we recommend the
hot water faucet be opened for several minutes at the
kitchen sink before any electrical applianceswhich are
connectedto the hot water systemare used(suchasa dis-
hwasber or washingmachine). If hydrogengasis present,
there will probably be an unusual sound similar to air
escaping through the pipe as the hot water faucet is
opened. There must be no smoking or open flame near
the faucetat the time it isopen.
