Good housekeeping will be required at all times by tenants and occupants of all buildings and hangars both in their assigned areas and during aircraft maintenance operations. Hangar floors shall be maintained clear of all engine stands, ladders and equipment not in actual use. Areas surrounding fire hydrants, fire extinguishers and sprinkler risers shall be kept clear at all times, and all premises shall be kept clean and clear of all rubbish, junk, debris, old aircraft and vehicles, and any other unsightly objects. If after warning by the manager, the area is not cleaned, cleaning will be done at the direction of the manager and billed to the tenant or occupant.
