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.
