Good washing facilities should be provided and good occupational hygiene measures should be followed, as described in the questions above, when dealing with bird droppings. Common activities, such as cleaning of windowsills, will not result in high exposures to infected material and are not high risk. For larger quantities, use of high pressure water should be avoided to minimise creation of droplets of water containing infected material, but wetting down the work area (using low pressure) will help to prevent inhalation of infected dust, reduce the risk of infection and will also prevent the spread of dust outside the work area. Containing the work area with plastic sheeting should also be considered. If required, following a risk assessment, for example when larger quantities of droppings are involved, a “P3” or “FFP3” mask should be used. These masks are designed to provide a good level of protection from particles in the air. A supplier of respiratory protective equipment (RPE) can help you choose the correct type of mask. If you need to use this kind of equipment you need to have a “face fit test” which is a test to ensure that the mask fits properly, before it is used. If the mask does not fit properly, it will not provide protection. Overalls should be worn when carrying out this work, and replaced when they are soiled.
