Are there any cooling towers at the building?

Has the cooling tower(s) been notified to the local authority?

Is there a written scheme for controlling the risk from exposure to legionella bacteria

Does the scheme contain an up-to-date plan of the system (a schematic plan is acceptable)?

Does the scheme contain instructions for operating the system?

Does the position of the cooling tower affect:

Are drift eliminators fitted?

Are they:

Is the area above the pond as enclosed as possible?

Are all visible surfaces free from:

Have all of the folowing been removed as far as possible:

Are all those parts of the tower that become wet, acessible and/or removable for cleaning?

Is the system in regular operation?

Are there procedures in place to operate standby equipment on a rotational basis?

Is there an operations manual for the cooling system?

If the tower is not in regular use, is it run once a week to circulate the treatment chemicals to all parts of the system?

If the tower is out of use for longer than a week, are there procedures in place to bring the tower back into operation safely?

Is there a watet treatment programme in place?

Are chemicals/biocides used to control:

If non-oxidising hiocides are used, are two types used alternately?

Are chemicals dosed automatically?

If yes, are the pumps calibrated regularly?

Is the physical condition of the system checked at least every week?

Is the chemical composition of the cooling and make-up water monitored on a regular basis?

Are the safe operating limits for each parameter which id being measured, known and recorded in the Water Treatment Log Book?

Is the corrective action for out of limits situations recorded in the Water Treatment Log Book?

Are the results of all tests and checks recorded?

Are details of all remedial actions taken, recorded in yhe Water Treatment Log Book?

Are dip slides taken on a weekly basis?

Does the scheme contain details of the checks that are to be carried out (and their frequency) to ensure that the scheme is effective?

Do any of the materials or fittings used in the water systems support the growth of micro-organisms?

Are low corrosion materisld used?

Are TMV's fitted in the system?

Are the TMV's fitted as close to the point of use as possible?

Are low use outlets installed upstream of higher used outlets?

Has the amount of cold water storage been assesed and minimised, i.e. holds enough water for a day's use only?

Is pipework insulated, and kept as far away from heat sources as possible?

Is the cold water tank:

Does the calorifier storage capacity meet normal daily fluctuations in hot water use while maintaining a supply temperature of at least 50°C?

Are the hot water distribution pipes insulated?

Are multiple calorifiers, connected in parallel in use?
