Remember...“A good housekeeping program is more than just a cleaning program. IAQ methods and training are critical.”
To be effective, a housekeeping program should be well designed, meticulously carried out, and monitored for effectiveness.
While housekeeping is a cleaning process, it also has the potential to add pollution to the environment because of the housekeeping methods. Sick building complaints sometimes result from chemical residues from cleaning agents or mold from wet areas left by untrained housekeeping personnel.
Personnel should be trained in proper cleaning methods for improved IAQ. Training in proper storage, and disposal methods; use of proper cleaning materials (e.g. lint free dusting cloths); proper use of equipment; proper cleaning and drying techniques for wet areas or after spills; and proper mixing and dispensing of cleaning agents. This is important to protect the housekeeping personnel, the occupants, and the building.

Remember...“Cleaning agents are sources of pollution and should be handled and used properly.”
Cleaning agents can contain irritating and harmful chemicals that may adversely affect housekeeping personnel, occupants, and building materials or furnishings.
All cleaning agents should be mixed accurately and safely, properly labeled, and used with strict adherence to manufacturers instructions and warnings.
Containers should have lids on tight when not in use, and agents should be stored in an area physically isolated from occupants, that has adequate exhaust and is always maintained under negative pressure.

(Cut out picture: Vacuuming as a Potential Pollution Source)

Remember...“Vacuum cleaners remove dirt but can also be a major source of dust.“
Vacuum cleaners remove dirt from carpets and floors. While most of the dirt is trapped and later discarded, some of the smaller particles escape back into the air and increase the concentration of particles in the air.
Vacuum bags should be replaced when full as per the manufacturer’s recommendations.
Using HEPA or other high efficiency vacuum systems may help reduce the quantity of particles that are released into the air.

(Cut out picture: Feather Dusters Can Be Inefficient)

Remember...“Feather type dusters have relatively low capacity to trap dust.”
Periodic high dusting is essential for a clean indoor environment. However, in this case, housekeeping personnel use feather type dusters to reach into hard to access places. These dusters have a relatively low capacity to trap dust, and a relatively high capacity to re-release the dust back into the air.
