Coils and traps should be valved off and drained. Humidifying
systems should be shut off and flushed, cleaned, and drained. Humidifying
pads or filtering elements not suitable for further use should be discarded;
usable pads and filters should be removed, cleaned, wrapped, and packed in
suitable containers. Pneumatic control systems, including compression
equipment, should be drained of water deposits and blown dry with compressed
air.
Mechanical Ventilating Systems. Surfaces of equipment and bearings
