1.Purpose

To make sure an unplanned equipment breakdown is reported, made safe, diagnosed and repaired quickly, and that the cause is reviewed so repeat failures are reduced.

2.Scope

Applies to unplanned breakdowns of production or facility equipment that stop or degrade normal operation. Scheduled preventive maintenance and routine work order requests are covered by separate SOPs.

Definitions

Breakdown
An unplanned stoppage or loss of function in a piece of equipment during normal operation.
Root cause
The underlying reason a failure occurred, as opposed to the immediate symptom that was repaired.
Mean time to repair
The average time from a breakdown being reported to the equipment being back in service.
Critical asset
Equipment whose failure has a major impact on safety, production or customer service, requiring the fastest response.

3.Responsibilities

Equipment Operator
Stops the equipment safely, reports the breakdown immediately, and stays available to describe the fault to maintenance.
Maintenance Technician
Diagnoses the failure, performs the repair, and documents the cause and actions taken.
Maintenance Supervisor
Coordinates the response, expedites parts, and decides when to escalate a critical asset failure.
Production Supervisor
Manages the operational impact of the downtime and confirms the equipment is ready to resume production.

5.Procedure

  1. 5.1

    Stop the equipment safely

    Equipment Operator

    Operator stops the equipment using the normal or emergency stop as the situation requires, and moves clear of any hazard such as a jam, spill or exposed moving part.

    Warning: Never reach into a jammed machine or attempt a quick fix on energized or moving equipment.

  2. 5.2

    Report the breakdown immediately

    Equipment Operator

    Operator reports the breakdown to maintenance and the production supervisor right away, describing the equipment, what happened, and any warning signs beforehand.

  3. 5.3

    Assess severity and dispatch a technician

    Maintenance Supervisor

    Maintenance supervisor assesses whether the asset is critical and safety- or production-impacting, and dispatches the appropriately skilled technician.

    Checkpoint: Critical asset breakdowns are dispatched to a technician within the site's target response time.

  4. 5.4

    Apply lockout/tagout before inspection

    Maintenance Technician

    Technician isolates and locks out all energy sources on the equipment before inspecting or touching any component, per the site's lockout tagout procedure.

    Warning: Do not inspect or repair the equipment before lockout/tagout is applied and verified.

  5. 5.5

    Interview the operator and review recent history

    Maintenance Technician

    Technician asks the operator what happened immediately before the failure and checks the asset's recent PM and repair history in the CMMS for clues.

  6. 5.6

    Diagnose the failure

    Maintenance Technician

    Technician inspects and tests the equipment to identify the failed component and the likely root cause, rather than only the symptom that stopped the machine.

  7. 5.7

    Expedite parts if not in stock

    Maintenance Supervisor

    If the needed part isn't in the spare parts inventory, the technician requests expedited sourcing from the maintenance supervisor, who approves the cost or arranges a temporary workaround.

  8. 5.8

    Execute the repair

    Maintenance Technician

    Technician repairs or replaces the failed component per the manufacturer's instructions or the applicable maintenance procedure.

  9. 5.9

    Remove lockout and test under load

    Maintenance Technician

    Technician removes lockout/tagout in the correct sequence, then runs the equipment under normal operating load to confirm the failure does not recur.

    Checkpoint: Equipment runs under normal load without recurrence of the fault before being released to production.

  10. 5.10

    Return the equipment to production

    Production Supervisor

    Technician confirms with the production supervisor and operator that the equipment is ready, and documents the handback time.

  11. 5.11

    Document the breakdown in the CMMS

    Maintenance Technician

    Technician records the failure mode, root cause, downtime duration, parts used and actions taken on the breakdown work order in the CMMS.

  12. 5.12

    Conduct a root cause review for repeat or critical failures

    Maintenance Supervisor

    Maintenance supervisor leads a root cause review with the technician and production supervisor for any repeat failure or critical asset breakdown, and assigns corrective actions to prevent recurrence.

6.Quality checks

  • โ†’Critical asset breakdowns are dispatched within the target response time at least 90 percent of the time.
  • โ†’Every breakdown work order records a root cause, not only the immediate symptom.
  • โ†’Repeat failures on the same asset within a set period trigger a root cause review.
  • โ†’Corrective actions from root cause reviews are tracked to completion.

7.Records

  • โ†’Breakdown work order in the CMMS
  • โ†’Root cause analysis forms
  • โ†’Expedited parts order log
  • โ†’Downtime and mean time to repair log

8.KPIs

  • โ†’Mean time to repair
  • โ†’Mean time between failures for critical assets
  • โ†’Percentage of breakdowns dispatched within target response time
  • โ†’Repeat failure rate on the same asset

9.Common mistakes

  • โ†’Restarting equipment to see if the problem clears itself instead of diagnosing it.
  • โ†’Skipping lockout/tagout because the repair looks quick.
  • โ†’Repairing the symptom without identifying or recording the root cause.
  • โ†’Not interviewing the operator, missing clues about what happened before the failure.
  • โ†’Skipping the root cause review after a repeat failure on the same asset.

Perfect Wiki AIExample answer

The same conveyor motor has failed three times this month, what should happen now?

This qualifies as a repeat failure that needs a root cause review: the maintenance supervisor should lead a review with the technician and production supervisor to find the underlying cause rather than replacing the motor again.Source: step 5.12 ยท Conduct a root cause review for repeat or critical failures
