PPG, NSF remind health inspectors of generic chlorine tablet risks

Booklet highlights safety and health dangers from improper use of chlorinator systems

PITTSBURGH, June 20, 2012 – In response to a recent survey conducted by the Water Quality and Health Council that found one in five adults urinates in the pool, NSF International and the ACCU-TAB(R) system commercial pool water treatment experts of PPG Industries (NYSE:PPG) once again remind aquatic health inspectors, pool owners and pool operators about the importance of using properly certified chlorine tablets in approved systems. They have co-published a free guide, “For Safety’s Sake,” explaining how to spot improper operation and warning about the dangers of using substitute tablets.

“The report is bringing the need to maintain proper levels of chlorine into sharper focus, so this is an ideal time for NSF and for health inspectors to educate pool owners and operators on the importance of using only chlorine tablets certified for use as part of an NSF-certified feeder system,” said Dave Purkiss, general manager of the water treatment and distribution products program at NSF International. “Failure to use tablets certified as part of an NSF Standard 50 chemical feeder system can not only put swimmers’ health at risk, but it can also place the pool out of compliance with state and local health codes that require NSF/ANSI Standard 50 certification.”

Substituting generic, or “knock-off,” tablets may create health and safety risks for patrons that could lead to health code violations and shutdowns. It can result in the under- or over-chlorination of water due to varying delivery rates, and it can increase the potential for noxious fumes and even fire or explosion caused by mixing incompatible chemicals.

“This is a reminder of the need to use the right chemicals in the right feeders,” said Dr. Stan Pickens, PPG senior research associate for the Accu-Tab chlorination system. “The use of tablets in a chlorinator system for which they were not intended can cause uncontrolled chlorine delivery rates and result in an inadvertent mixing of incompatible chemicals that may generate heat or release toxic gas, potentially causing a violent detonation in the feeder.”
