WMSoc Training Courses - Legionella Risk Assessment of Other Risk Systems - W270

City & Guilds accredited
ONE-DAY COURSE:  9.15am – 4.30pm
Lunch and refreshments provided
Printed delegate materials provided



Risk assessors who want to or who may encounter, other risk systems where there is limited guidance.  Delegates should have training and experience before attending this course.

This is not an entry level training course for new risk assessors. This course is suitable for people who posses surveying and legionella risk assessment experience for complex water systems. Candidates should be comfortable risk assessing without supervision and with minimal support. Ideally, they should understand controls and treatment for other risk systems. if further knowledge is required, then we would strongly recommend delegates attend a foundation course in cooling tower chemistry or spa pool water treatment and gain some in-field water treatment experience.

Candidates must have a very good working knowledge of L8, HSG 274 Parts 1 and 3 and HSG 282 including knowledge of principles of risk assessment, principles of control, documentation requirements and management structures outlined within these documents. In addition they should have a good understanding of the microbiology, history and legislation related to the control of legionella. These aspects will only briefly be covered in an interactive revision session, to reinforce this understanding.

Students should attend:

  • W264 Legionella Risk Assessment of Hot & Cold Water Systems Foundation
  • W265 Practical Legionella Risk Assessment Hot & Cold Water Systems Advanced
  • W266 Legionella Risk Assessment of Evaporative Cooling Systems
  • W252 Water Treatment Chemistry Foundation
  • or have equivalent practical surveying and risk assessing knowledge prior to attending this course.
This is not a course for candidates who have just started out in their risk assessing role, they should attend the previously mentioned courses and have prior assessing experience. 

Pre-reading of L8, HSG 274 parts 1 and 3 and HSG 282 would be beneficial (available as a free download from the HSE website).

An understanding of the principles behind CATES, ALARP and compliance where there is no specific guidance on the water systems involved.  Risk assessment for these potentially more complex systems where the use of first principles is paramount. Including recommendations for remedial actions and design of control measures.

This is achieved with PowerPoint presentation, through group exercises and classroom discussions on the findings of the exercises. Therefore, candidates should be prepared for the course to be interactive and that they will be required to be collaborative and provide their contributions to the discussions arising on the day.
Revision session on legal and practical requirements for and effective and compliant legionella control programmes.

Group exercises based around written scheme of control records and conclusions to draw from these records.

  • Spa pools and hot tubs 
  • Metal working fluids 
  • Aqueous parts washers  
  • Injection moulding machine coolant 
  • Ultrasonic humidifiers 
  • Irrigation systems 
  • Spray humidifiers 
  • Wet spray 
  • Water features and decorative 
  • Water softeners 
  • Emergency showers and eyewash fountains
  • Dental water line systems
The day includes classroom teaching with interactive discussions and analysis of records.
60 minute written exam with 70% pass mark. Questions are short form answers and scenario-based answers. The students are provided with an outline set of slide notes at the beginning of the day and are encouraged to make further notes as the course progresses, particularly as the teachning is discussion led. These notes are available to students during the exam.

A resit is possible for anyone failing the exam for an additional fee.

6 CPD points awarded.

Electronic certificates will be sent directly to successful candidates to the email address we hold on file.
