temperatures required for automatic dishwasher and laundry use can cause scald burns resulting in serious
personal injury and/or death. The temperature at which injury occurs varies with the person's age and the
time of exposure. The slower response time of the elderly and disabled persons increases the hazards to
them. NEVER allow small children to use a hot water tap or to draw their own bath water. NEVER leave a
child or disabled person unattended in a bathtub or shower.
