Legionella Testing for Dental Surgeries and Practices

Dental practices legally require Legionella risk assessments

The law regarding legionella risk assessments

All dental surgeries and practices in the UK are legally required to have a legionella risk assessment of all hot and cold water systems.

The risk assessment is usually carried out as a part of a legionella risk management programme arranged by specialists who help manage the risk of Legionnaires disease.

The legionella risk assessment programme provided by the team adheres with the guidelines and recommended practices issued by the UK Health & Safety Executive L8 and the Health and Safety Commission (HSC) and the Department of Health"s guidance documents:

• Health Technical Memorandum 01-05: Decontamination in Primary Care Dental Practices (HTM01-05)
• Health Technical Memorandum 04-01: The control of Legionella, hygiene, "safe" hot water, cold water and drinking water systems (HTM04-01)


How could legionella bacteria be transmitted to staff and patients?

The main method for transmission of legionella bacteria to patients and staff is the inhalation of contaminated water droplets or the aerosol generated by dental equipment such as a ultrasonic scaler or high speed hand piece.

Masks worn by staff provide limited protection but the patient can easily inhale the aerosol. As such it is very important that the water used during dental procedures is of a very high quality which does not a pose a risk.


What does legionella risk assessment involve?

• Assessment of water systems and storage for compliance with Water Supply (Water Fittings) Regulations 1999
• Water temperature testing for effective legionella bacteria control
• Actions required for compliance e.g. cleaning and disinfection of water systems and storage
• A schedule for water monitoring
• Understanding of legionella control for your premises and documentation for HSE/HSC
• Identification of on-site training requirements

Water testing for legionella is undertaken at an accredited laboratory.
