Safety Training

BOHS P 903 – Legionella – Management and Control of Evaporative Cooling and other High Risk Industrial Water Systems

Course Date(s) 21st June 2019

Aims:

To provide background and an overview of the risk of legionella infection and how it can be controlled in Evaporative Cooling and other high risk Industrial type systems.
It is a requirement of this course that candidates have successfully completed P901 Legionella Management and Control of Building Hot and Cold Water Services.
Where both P901 and P903 courses are run on subsequent days or as a combined course then this prerequisite is waived.

Prior Knowledge

In addition to completion of the BOHS P901 Legionella Management and Control of Building Hot and Cold Water Services;candidates are also expected to have a working knowledge of the HSE Approved Code of Practice and technical guidance Legionnaires’ disease. [The control of Legionella bacteria in water systems-l8] and the guidance contained in HSG274 parts 1 and 3


Course Content:

On successful completion, the student shall be able to demonstrate management control of industrial and process water systems including open evaporative cooling systems incorporating one or more cooling towers

The legionella infection risk posed by open evaporative cooling systems and the use of treatment regimes to control that risk

The key components of open evaporative cooling systems and their principal functions,including in general terms the operation of drift eliminators

Identifying and understanding in general terms the key elements of a chemical treatment regime for open evaporative cooling systems, the hardness cycle, base exchange softening, corrosion control, the effect of increasing pH on halogen biocides, concentration factor, bleed and half life

The risk assessment approach to fill pack removal for cleaning, including means of appraising cleanliness

The legionella infection risk posed by air humidification systems, fogging and misting devices, air scrubbers
and regimes of control Emergency water systems: fire, safety showers, eye wash stations and regimes of control. Stand alone or fixed washing devices for vehicles, components, products or other items
