3.4.2 Safety
During the course of an outbreak investigation, sampling staff may be exposed to potentially infectious aerosols.
Appropriate precautions should, therefore, be taken during sampling operations to minimise the production of, and exposure to, aerosols.
- Where appropriate, taps should be turned on and water run gently to reduce the amount of splashing.
- Whenever possible, samples should be taken from cooling systems at sample point locations situated on the return service to the cooling water to the tower, and as near as possible (in terms of pipe length) to any heat source.
Individual staff who may be prone to an increased risk of Legionella infection should not be involved in sampling operations, particularly when investigating outbreaks.
- If the safety of staff is a cause for concern, then full respiratory protection should be made available for staff who are aware of the risks and have been trained in their use (4).
