The HSE has launched new guidance HSG 282 aimed at managing and controlling the risks from legionella and other infectious agents in spa-pool systems.


With a number of outbreaks linked to facilities in leisure centres, hotels, holiday homes, on cruise ships and on display, the guidance will immediately help managers and operators of such systems control the quality of water contained within their spa-pool systems. The legislation is also greatly beneficial to service suppliers, designers, manufacturers, importers, suppliers and installers of systems to help meet their legal responsibilities.

After a healthy period of consultation with manufacturers and suppliers of disinfection technologies, the HSE has listed silver stabilised hydrogen peroxide (SSHP) as an approved disinfectant within the new guidance. This places EndoSan perfectly as it is the most advanced SSHP available on the market.

The inclusion of silver stabilised hydrogen peroxide in HSG 282 can be found on page 42 of The control of legionella and other infectious agents in spa-pool systems:

“SSHP is a broad spectrum disinfectant usually supplied as a solution to be dosed or added to the spa-pool system. It comprises a solution of hydrogen peroxide, stabilised using proprietary ionic silver-based chemistry. The usual recommendation is a shock dose of the water to remove any existing biofilm or biofouling from the system, normally carried out at 100 ppm for a minimum of 12 hours. Higher concentrations may be required depending on the condition of the facility. The spa or hot tub can then be operated with a hydrogen peroxide residual of 50 ppm (30 ppm to 70 ppm hydrogen peroxide). No pH adjustment is required.”

The advice provided by the HSE will be invaluable for spa-pool systems (including hot tubs, Jacuzzis, birthing pools, plunge pools, sports rehab and therapy pools) through:

  • Design, commissioning, operation and maintenance.
  • Testing and monitoring water quality.
  • Quality and frequency of inspection.

Ben Sallon, Managing Director of Endo Enterprises (UK) Ltd said:

“We are delighted that the new legislation places EndoSan in a great position to help control the microbiological quality of notoriously risky spa pools. We also appreciate the excellent work carried out by the HSE on HSG282 and subsequent consultation to help make spa pools safer and easier to maintain for all concerned. With spa pools providing the perfect temperature for bacteria to thrive and the inherent capacity they have to produce aerosols, this guidance will be invaluable to take advantage of the best chemistry to reduce risk to both owners and users.”
