Hot Water Can Scald!
Water heated to temperature for
clothes washing, dish washing and
other sanitizing needs can scald and
cause permanent injury.
Children, elderly, and infirm or
physically handicapped persons are
more likely to be permanently injured
by hot water. Never leave them
unattended in bathtub or shower. Never
allow small children to use a hot water
tap or draw their own bath.
• If anyone using hot water in the
building fits the above description,
or if state laws or local codes
require certain water temperatures
at hot water taps, you must take
special precautions:
• Use lowest possible temperature
setting.
• Install some type of
tempering device, such as an
automatic mixing valve, at
hot water tap or water heater.
Automatic mixing valve must
be selected and installed
according to manufacturer's
recommendations and
instructions.
Water passing out of drain valves may
be extremely hot. To avoid injury:
• Make sure all connections are tight.
• Direct water flow away from any
person.
