Room G.23 (Plant Growth Room) Exhaust Filter Cleaning Program

The intakes of the exhaust ducts in this room are protected by fine mesh to exclude the entry of insects, arthropods and other vermin. These are cleaned annually or when there is visually contamination.

The mesh is cleaned in situ with a vacuum cleaner.

Cleaning is recorded in the diary kept in the room for this purpose.
