A 12-Step Program for Avoiding Liability for Hot Water System Injuries – Plumbing Systems and Design

A 12-Step Program for Avoiding Liability for Hot Water System Injuries.
Plumbing Systems and Design 2007; Vol. 6: No. 1
by Wise, Donald

Plumbing engineers, designers, contractors, maintenance, and operating personnel are often involved in litigation concerning liability for injuries sustained by the users of hot water systems. For example, scald injuries and legionella danger occur when hot water is not maintained at an optimal temperature. These dangers are greatest for the old and the young. These age groups will grow in absolute and relative numbers in the United States for some time to come. Thus, litigation regarding hot water injuries is anticipated to increase. Hot water injuries are preventable. Implementation of best practices for hot water systems is a prudent step. Based on existing industry standards and guidelines, these best practices apply to the design, build, operate, and maintenance aspects of hot water systems. Practices to directly control hot water systems include: 1. Minimize hot water temperature. Methods to bring water to taps within a variety of systems at a temperature of approximately 122 degrees are presented, along with reasons behind this temperature choice. Legionella-contaminated systems are also discussed. 2. Point-of-use, pressure-regulated thermostatic mixing valves are required on new bathing installations. Install on kitchen taps, where not required, to prevent scalds. Retrofit existing showers and baths with cutoff devices. 3. Install redundant protection to ensure that water too hot for safety does not reach taps. Redundancy for small and large systems is discussed. 4. Verify and document hot water system performance by testing under a variety of conditions prior to placing into service. Ongoing testing and periodic monitoring for legionella bacteria are recommended. 5. Recirculate water continuously. Use of energy management systems on recirculating hot water systems can result in pockets of water that rise above or fall below safety levels. 6. Properly size pipes to ensure that a system does not experience surges of hot water as a result of instantaneous demand at another fixture. 7. Maintain the domestic hot water system or ensure that building owners understand the need to do so. 8. Adjust mixing valves on central boilers to accommodate fluctuations in ambient temperature and demand. 9. Prevent mineral deposit buildup that can decrease pipe diameters and provide conditions that allow legionella bacteria to grow. 10. Periodically assess the hot water system to help identify when design conditions have changed and adjustments are necessary. 11. Do not increase water temperatures in an attempt to meet the needs of an inadequate or aging hot water system. 12. Replace damaged parts, particularly mixing valves.

CO2 Emissions from Fuel Combustion

CO2 Emissions from Fuel Combustion

2010, 542 pages, ISBN 978-92-64-08027-8,
Type: Statistics Publication and CD-ROMs


In recognition of fundamental changes in the way governments approach energy-related environmental issues, the IEA has prepared this

publication on CO2 emissions from fuel combustion. This annual publication was first published in 1997 and has become an essential tool for

analysts and policy makers in many international for a such as the Conference of the Parties.

The sixteenth session of the Conference of the Parties to the Climate Change Convention (COP 16), in conjunction with the sixth meeting of

the Parties to the Kyoto Protocol (CMP 6), will be meeting in Cancún Mexico from 29 November to 10 December 2010.

The data in this book are designed to assist in understanding the evolution of the emissions of CO2 from 1971 to 2008 for more than 140

countries and regions by sector and by fuel. Emissions were calculated using IEA energy databases and the default methods and emission

factors from the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories.
