Scalding hot water from fixture faucets and fittings accounts for more than 25 percent of all scald burns in children. The elderly and the physically impaired also are at increased risk of scald burns because they have thinner skin and slower reactions. They often cannot recognize a hazard and get out of harm’s way before a serious burn can occur.
We now know that storing water at 110 F, as was called for in many energy conservation mandates in the 1970s, can lead to an increase in Legionella bacteria growth in the hot water storage and distribution systems, which could eventually lead to outbreaks.
Health care facilities should have a regimen of testing water systems and use supplemental disinfection to control the Legionella bacteria.

We have learned much about controlling the growth and spread of Legionella bacteria in water systems. Health-care facilities are especially vulnerable. ASHRAE-compliant water management programs can reduce the risk for Legionella and other pathogens in their water systems.
A properly balanced recirculation system offers health and safety benefits.

To achieve comfort and efficiency in a hot water distribution system, many plumbing engineers are incorporating hot water recirculation systems into their designs. But to reap the benefits of such a system, balancing valves must be incorporated into design considerations.
The material of the piping itself can impact the likelihood of a Legionella issue.
