Pre-outbreak planning - training and safety

Individuals taking samples should have received training in risk assessment and control of Legionella.

Sampler training should include:

• Basic microbiological sampling - aseptic technique
• Knowledge of the ecology of the organisms and factors affecting its occurrence (see Developing Understanding)
• Knowledge of risk assessment
• Labelling and record keeping
• Legal requirements - continuity of evidence
• Knowledge of where to sample and correct bottle to use
• Be well practised in coordination with laboratory
• If possible, keep a set of sampling equipment and materials ready for outbreak investigations

Safety aspects

1. Take precautions to minimise exposure
   • Minimise aerosol formation
   • Avoid exposure to aerosols
   • • Run taps gently
     • Don't operate sprays and showers
     • Switch off cooling tower circulation etc
2. In outbreak investigations
   • Sampler should not be in a highly susceptible group (immunosuppression, transplant recipients and heavy smokers)
   • Advise anyone susceptible on site about health awareness
   • Sampler may (very rarely) need to be trained to wear respiratory protective equipment (RPE) - anticipate through risk assessment
3. General safety
   • Sampler should be trained in safe use of ladders and take appropriate safety precautions
   • If sampling in a home, sampler should wear personal protective equipment to avoid contact with or inhalation of insulation materials
