Example of a site specific TLS

the manager for guidance, who most likely on a bank holiday has his/her phone switched off. This is what a Traffic Light System can provide – instant critical responsibility for a reaction.

A TRAFFIC LIGHT SYSTEM (TLS) This is a simple application of recommendations that can be applied to many tasks and operations, and one that should be understood by all who have responsibility for testing.

Plus, this system ensures results and activities/reactions are recorded correctly in line with legal requirements. Specifically, the TLS is based on recognition of the parameters recommended and applied to water based testing systems. The parameters are defined, stated and applied from national recommendations.

The system comprises three main parts: • Testing • Reaction • Recording

The three conditions are: GREEN, AMBER, RED.

CONDITION GREEN: • All up to standard • Results recorded • No reaction required. Signed off

CONDITION AMBER: • Results outside set parameter, but still safe to bathe

• Demands an action is completed in reaction to the results

• A retest takes place • TLS applied again • The reaction log is filled in with activity detail, and if retest is back to green signed off

CONDITION RED: • Facility closed until actions taken bring levels back to acceptable

• Tests taken until readings acceptable i.e. return to within green zone

• May require a full suite of bacteriological tests

Now we have a defined policy to work to. We have set limits. We have reactions to potentially dangerous situations. We are in control! These are legal requirements.

CONSEQUENCES OF NON- COMPLIANCE WITH POOR CONTROL The consequences of lax, short-term attitudes to pool plant operations can prove very costly for the industry. An outbreak can also be very damaging for a centre’s reputation, and could result in an investigation from enforcing officers. In extreme cases, prosecution and legal claims can be made related to illness caused by poorly treated pool water. A recent incident where the pool had no consistent results recorded and no reaction policy or logs tragically resulted in fatalities and serious illness. This is now being dealt with via a civil court.

THE IMPORTANCE OF TRAINING In response to these challenges and in line with modern-day thinking, STA’s Level 2 and Level 3 Swimming Pool and Spa Water Treatment qualifications delivers content that is up-to-date, relevant to the needs of its learners and at costs that meet current economic requirements.

They cover half-day awards in Water Testing through to three-day Pool Plant Operators qualifications. Uniquely, the Level 3 Pool Plant Operators course contains chapters on Spas, Interactive Play Features, Energy Conservation and Health & Safety. The syllabus also covers the special demands of hydrotherapy pools to ensure that staff responsible for the management of pools in facilities such as special schools and hospitals, where hydrotherapy pools are common, are trained to the correct standard and are able to maintain safe bathing conditions. All the awards are supported with extensive learning materials too, including a comprehensive new manual that covers all of the new unitised courses in detail, supported with user-friendly colour images and diagrams – and acts as a useful reference document. As a further step, STA has also introduced online revalidations for pool and spa plant operators. Pool Plant Operators can now revalidate their qualifications online for just £65 and qualifications from CIMSPA, Active IQ and ISPE are all accepted for conversion / revalidation to STA.

Using a defined Traffic Light System, results are clear within STAadmin’s Pool Plant programme further simplifies the process of pro- actively controlling and maintaining the correct water chemistry levels in a pool or spa. The system, developed by STA’s pool plant experts allows users to input chlorine, bromine or pH pool readings in real time. Within seconds, the data is analysed and presented in a simple graphical format with the traffic light system denoting the status of the water.

The results are then instantly emailed to the nominated person(s) for follow-up, with all immediate actions highlighted. Uniquely, STA’s new digital Photometer also links via Bluetooth to STAadmin.’s pool plant management programme, for real time analysis, instant email alerts and reporting. The ‘5-in-1’ and ‘balanced water’ photometer kits, which read chlorine (free / total / combined), pH, cyanuric acid, calcium hardness, and alkalinity, also analyse results 100 times faster than the next leading brand and require minimal calibration, saving pool mangers time and money.
