Inspection Scope and Area Identification

Document the specific room, line, equipment area, or process zone included in this audit.
Verify that the facility has a documented combustible dust hazard assessment supporting the housekeeping program.
Confirm the area has a defined inspection and cleaning frequency based on dust generation and risk.
Enter the date and time of the most recent housekeeping inspection for this area.

Dust Layer Management

Check whether dust layers on floors, ledges, beams, cable trays, equipment, and other surfaces remain below the site's defined action level.
Measure representative dust layer thickness at the inspected location.
Verify that beams, rafters, tops of equipment, light fixtures, ducting, and other horizontal surfaces are not allowing hazardous dust accumulation.
Confirm that housekeeping practices prevent dust from spreading into walkways, offices, electrical rooms, or other non-process areas.
Review whether cleanup logs or work orders show dust accumulation is addressed within the required timeframe.

Vacuuming and Cleanup Practices

Confirm that vacuuming is performed with equipment approved for combustible dust service and appropriate for the dust hazard classification.
Verify that compressed air is not used for routine cleaning unless specifically controlled, justified, and performed with safeguards.
Observe whether sweeping, blowing, or other cleanup activities are avoided when they would create airborne dust clouds.
Inspect vacuum equipment for damage, leaks, clogged filters, or full collection containers that could reduce effectiveness or create ignition risk.
Confirm that removed dust is transferred and stored in closed, labeled containers to prevent re-entrainment and ignition exposure.

MAQ Controls and Dust Storage

Verify that the facility has established and communicated a maximum allowable quantity for combustible dust in the inspected area.
Confirm that dust, dust waste, and recovered material stored in the area do not exceed the defined MAQ.
Check that containers used for combustible dust are labeled, covered, and managed to prevent release and ignition.
Verify that transfer points, hoppers, bag dumps, and similar locations are cleaned before dust overflows or accumulates excessively.

Ignition Source Prevention

Verify that hot work is controlled by permit, isolation, and cleanup requirements when performed in or near combustible dust hazards.
Inspect motors, panels, junction boxes, lighting, and controls for dust accumulation that could create overheating or ignition risk.
Confirm bonding, grounding, or other static control measures are used where dust cleanup or transfer could generate static discharge.

Corrective Actions and Sign-Off

List all deficiencies, non-conformances, and required corrective actions identified during the inspection.
Record the name or role responsible for corrective action tracking and closure.
Inspector signs to confirm the audit findings are complete and accurate.
