Emergency Flushing of Building Water Systems

The presenter will cover the proper way to perform an emergency flush and disinfection procedure following a lengthy shut-down of a building. The Corona Virus 2019 (Covid-19) pandemic has caused many states to order citizens to stay at home and shelter in place to minimize the spread of a virus. When buildings are shut down for long periods of time, the water in the buildings piping systems will lose its water treatment chemicals as the chemical oxidize or dissipate over time to levels that are too low to control Legionella bacteria and other microorganism growth. Flushing building water systems prior to building occupancy will be critical to prevent illnesses due to bacteria in stagnant water. This seminar will offer timely and critically important information on how to properly perform and document this procedure. In addition, it will discuss steps to develop a building water safety plan and building water management team to perform a risk assessment of the buildings water systems to assure control of bacteria growth. In addition, the seminar will cover the key points in the ASHRAE 188 Standard titled: Legionellosis: Risk Management for Building Water Systems and ASHRAE Guideline 12 -2000 Minimizing the Risk of Legionellosis associated with Building Water Systems.
