Cooling Towers
The safe operation of evaporative cooling tower equipment is governed by the requirements of the HSE document: Approved Code of Practice - L8 (ACoP L8), which gives practical guidance with respect to the Health and Safety at Work etc, Act 1974 and the Control of Substances Hazardous to Health Regulations 1999 (COSHH).
This publication contains the Approved Code of Practice and Guidance and applies to the risk from Legionella Bacteria in circumstances where the Health and Safety at Work Act applies. It is a benchmark against which all legal duties, procedures, maintenance programmes and management regimes may be compared.
Section 57 (d) states:
“Keeping the system clean to avoid the build-up of sediments which may harbor bacteria (and also provide a nutrient source for them).”
Section 138 states:
“Where practicable, the packs should be removed at least once per year and preferably every six months. If this is not practicable, it may be necessary to apply supplementary strategies such as side-stream filtration, increased monitoring etc. Endoscope inspections of packing modules are an acceptable supplementary strategy and as such may be used to determine the need for pack removal for cleaning or the cleaning of pack in situ.”
