Good housekeeping removes or controls the fuel that allows a small ignition source to become a workplace fire. It also supports safe evacuation, emergency access, and routine inspection programs.
For the ASP exam, connect housekeeping practices to combustible load control, safe storage, dust accumulation, and unobstructed means of egress.
Routine removal and safe containment reduce the available fuel load.
Collect paper, cardboard, wood scraps, packaging, and other combustible waste on a schedule that matches the hazard level. Keep accumulations away from ignition sources and electrical equipment.
Use covered, noncombustible containers when waste must remain in the work area temporarily. Empty containers before waste creates an excessive fuel load.
Certain oils can generate heat as they oxidize and may ignite without an external flame.
Rags contaminated with drying oils, such as linseed oil, can self-heat through oxidation. Piled or poorly ventilated rags are especially hazardous because heat cannot dissipate.
Place oily rags in listed, self-closing metal containers and arrange for regular disposal. Do not leave them in open bins, pockets, or on equipment.
Clear pathways help people leave safely and allow emergency responders to reach hazards.
Keep exits, aisles, corridors, stairways, and doors free of storage, equipment, and debris. An obstruction in a required means of egress is a life-safety hazard.
Do not block portable extinguishers, alarms, hose connections, electrical disconnects, or emergency shutoffs. Mark and maintain the access space around critical equipment.
Fine combustible dust can become fuel for a flash fire or a damaging secondary explosion.
Check beams, ledges, ducts, equipment tops, and other horizontal surfaces where dust can settle. A dust layer away from the original event can fuel a secondary explosion.
Use vacuum systems or other methods that capture dust. Avoid compressed air or dry sweeping when those methods could create a combustible dust cloud.
A documented program turns housekeeping from an occasional activity into a reliable fire-prevention control.
Inspect work areas at a frequency appropriate to the materials, processes, and rate of waste generation. Pay close attention to storage, maintenance areas, and concealed spaces.
Record findings, assign responsibility, and verify completion. Repeated conditions may indicate a need to change storage practices, collection frequency, or worker training.
