The ACOP L8 regulations indicate that a suitable and sufficient risk assessment is the first step in Legionnaires’ Disease prevention. The objective is to identify all water systems where legionella bacteria could potentially grow and assess the risk of people being exposed to contaminated aerosols from them. All water systems need to be included in the legionella risk assessment, but particular attention needs to be paid to the systems that fall within the categories of process water and domestic water shown below.

•Prepare a scheme for preventing or controlling the risk

•Implement and manage precautions

•Keep records of precautions implemented

•Appoint a person to be managerially responsible

 

This must be carried in order to monitor the domestic - Hot & cold water systems

Particular attention should be given to managing spray forming outlets and - Domestic Showers

The main protection you have in managing the prevention of legionella is water temperature, however if water temperature cannot be controlled to reduce the risk an alternative such as Chlorine Dioxide (see below for more details).

Domestic Water System

Domestic Water Systems are found in the majority of properties, under the Health and Safety at work act 1974, it is the responsibility of the statutory duty holder to put in place the following

•Cooling water systems, cooling towers and evaporative condensers

•Spa pools

•Spray humidifiers, misters, air washers and wet scrubbers

•Safety showers, sprinklers, vehicle wash systems

•Fountains and water features

•Any other system containing water in which Legionella could grow and be released in aerosol droplets.

 

Again as in the domestic water systems, once risk is identified those risks should be managed to ensure that all that is practically possible is being carried out to negate the risk to persons in contact with the effects of the water systems being maintained.

All this can be a bit daunting, so Tritec as well as providing the services detailed in this section have developed a comprehensive range of products and services to help you in all aspects of legionnaires disease prevention and aspects of legionella L8 compliance – See Specialist Services.
