Objective

To provide workers with practical guidance for conducting asset inspections safely, identifying defects and hazards early, applying risk-based controls, and ensuring defective or unsafe assets are reported, isolated, and removed from service in accordance with workplace safety and asset integrity requirements.

Introduction

Asset inspection is a critical part of preventing injuries, equipment damage, and unplanned downtime. A thorough inspection helps verify that equipment is in safe working order before use, identifies wear or damage before it becomes a failure, and supports asset integrity by ensuring defects are corrected and recorded. Poorly maintained or damaged equipment can create slip, crush, electrical, and struck-by hazards, and unexpected startup or release of stored energy can cause serious injury or death. Effective inspection practices depend on competent people, clear checklists, prompt defect reporting, and lockout/tagout when maintenance, cleaning, repair, or adjustment is required.

Presenter Note: Open by linking inspection to both worker safety and equipment reliability. Emphasize that inspection is not a paperwork exercise; it is a frontline control that prevents incidents and protects production.

Key Points

• 1. Inspect Before Use and at Required Intervals: Every asset should be inspected before use to confirm it is in safe working order and good repair. In addition to pre-use checks, periodic inspections must be completed according to the asset type, manufacturer guidance, site procedures, and legal requirements. The purpose of the inspection determines whether it is a normal operational check or a servicing/maintenance activity. If the inspection is being used to troubleshoot a problem or verify a repair, it may fall under hazardous energy control requirements. [1] [9]
  • Use the correct checklist for the specific asset.
  • Do not assume a machine is safe because it was working earlier in the shift.
  • Escalate any abnormal condition immediately rather than continuing to operate the asset.
• 2. Identify Hazards During the Inspection: A safe inspection looks for conditions that could cause injury, equipment failure, or loss of control. Common hazards include leaks, damaged guards, worn components, missing fasteners, electrical defects, unstable supports, and signs of stored energy. Inspectors should also consider the work environment, such as slippery surfaces, poor lighting, congestion, or exposure to moving parts. The goal is to identify both immediate hazards and conditions that could worsen if the asset remains in service. [2] [5]
  • Look for visible damage, abnormal noise, vibration, heat, odor, or leakage.
  • Check that guards, covers, interlocks, and warning devices are in place and functional.
  • Assess the surrounding area for slip, trip, struck-by, and pinch-point hazards.
• 3. Apply Risk Assessment Before Continuing Work: When a defect or abnormal condition is found, assess the risk by considering the likelihood of failure and the severity of the possible consequence. High-risk conditions such as exposed moving parts, compromised lifting components, electrical damage, or hydraulic leaks should trigger immediate removal from service. Lower-risk issues may still require prompt correction, but the asset should only remain in use if the condition does not create an unacceptable hazard and the responsible supervisor approves continued operation under site rules. [11]
  • Consider who could be exposed and how they could be injured.
  • Treat defects that affect safety-critical functions as priority issues.
  • Use the site risk matrix or equivalent decision process where available.
• 4. Report Defects Immediately and Remove Unsafe Assets from Service: Any defect that could affect safe operation must be reported without delay to the supervisor or designated competent person. The asset should be tagged, isolated, and taken out of service when necessary so no one else uses it before repairs are completed. Reporting should include what was found, where it was found, the asset identification, and whether the defect is worsening or creating an immediate hazard. Clear reporting supports traceability, maintenance planning, and asset integrity records. [1] [2]
  • Use a consistent defect reporting process or form.
  • Clearly identify the asset status: safe, restricted, or out of service.
  • Do not bypass defects or continue using damaged equipment.
• 5. Use Lockout/Tagout When Maintenance, Cleaning, Repair, or Adjustment Is Required: If inspection leads to maintenance, cleaning, repair, servicing, set-up, or adjustment, hazardous energy must be controlled before work begins. This includes electrical, mechanical, hydraulic, pneumatic, thermal, and stored energy sources. Lockout/tagout is the primary method for preventing unexpected startup or release of energy. Only trained and authorized employees should perform these tasks, and the equipment must not be returned to service until all guards are replaced, the work area is clear, and the asset is verified safe. [3] [4] [1]
  • Identify all energy sources before starting work.
  • Isolate, lock, tag, and verify zero energy before touching the asset.
  • Follow site-specific procedures for group lockout, shift changes, and contractor control.

Hazard Identification

Asset inspection work can expose workers to hazards from the asset itself, the surrounding area, and the inspection process. The following hazards are commonly encountered during pre-use and periodic inspections and must be controlled before work continues.

• Unexpected startup or movement of equipment during inspection or follow-up maintenance: Crushing, entanglement, amputation, struck-by injuries, or fatality if a worker is in the danger zone when the asset energizes or moves. [3] [5]

(Risk: High)

• Stored or residual energy in electrical, hydraulic, pneumatic, mechanical, or thermal systems: Shock, burns, injection injuries, sudden release of pressure, moving parts, or uncontrolled motion during inspection or repair. [4] [5]

(Risk: High)

• Slips, trips, and falls caused by leaks, debris, poor housekeeping, or unstable access conditions: Sprains, fractures, head injuries, or secondary contact with moving or energized equipment. [2]

(Risk: Medium)

• Contact with damaged, worn, or missing guards and components: Cuts, lacerations, entanglement, pinch-point injuries, or exposure to rotating or moving parts. [1] [2]

(Risk: High)

• Inadequate inspection documentation or failure to communicate defects: Unsafe equipment may remain in service, defects may be repeated, and maintenance or corrective actions may be delayed or missed. [1] [10]

(Risk: Medium)

Presenter Note: Ask participants to name defects they have seen recently and discuss which ones required immediate shutdown versus scheduled repair. Reinforce that a small defect can become a major failure if ignored.

Control Measures

Use the hierarchy of controls before relying on PPE alone. First, eliminate the hazard by removing the asset from service or isolating the energy source. Next, apply engineering controls such as guards, barriers, interlocks, or blocking devices. Then use administrative controls such as checklists, competent-person review, permit systems, and defect reporting. PPE is the last line of defense and does not replace safe inspection practices or lockout/tagout.

• Use a task-specific inspection checklist for each asset type: Include pre-use items, periodic inspection items, safety-critical components, and acceptance/rejection criteria. Keep the checklist available at the point of use and require completion before the asset is released for operation. [6] [12]
• Assign inspection and sign-off responsibilities to a competent person: Ensure the inspector understands the equipment, the hazards, the inspection criteria, and the authority to remove unsafe equipment from service. Competent persons should verify findings, escalate critical defects, and maintain consistency across shifts. [3]
• Isolate and lock out hazardous energy before maintenance or repair: Identify all energy sources, shut down the asset using the correct sequence, isolate the energy-isolating devices, apply locks and tags, and verify zero energy before work begins. Use group lockout when more than one worker is involved. [4] [7]
• Remove defective assets from service and clearly tag them out: If a defect creates an unsafe condition, stop use immediately, attach an out-of-service tag or equivalent warning, and prevent re-energization until repairs are completed and verified. Communicate the status to affected workers and supervisors. [2] [5]
• Maintain accurate maintenance and inspection records: Record the date, asset identification, findings, corrective actions, parts replaced, and the name of the person completing the inspection or repair. Use records to identify recurring defects and schedule preventive maintenance before failure occurs. [10] [13]
• Verify the work area is safe before returning the asset to service: Confirm that tools, debris, and temporary guards are removed, all guards are reinstalled, and all workers are clear of danger zones. Notify affected employees before restart and test the asset in a controlled manner. [4] [7]

Safe Work Procedures

1. Review the asset-specific inspection checklist, manufacturer instructions, and site procedures before starting. Confirm the inspection frequency, required PPE, and any permit or authorization requirements.
2. Inspect the asset in a safe location with adequate lighting and access. Look for leaks, damage, missing guards, loose parts, abnormal wear, unusual noise, overheating, and signs of instability or contamination.
3. If a defect is found, stop and assess whether the asset can remain in service. If the condition is unsafe or uncertain, remove the asset from service and notify the supervisor or competent person immediately.
4. If maintenance, cleaning, repair, or adjustment is required, isolate all energy sources and apply lockout/tagout before any work begins. Verify zero energy and control stored energy before touching the asset.
5. Complete the inspection record, defect report, or maintenance request. Include the asset ID, location, observed condition, immediate controls applied, and the corrective action required.
6. Before returning the asset to service, confirm that repairs are complete, guards are reinstalled, tools are removed, and all workers are clear. Remove locks and tags only according to site procedure and authorization rules.

Presenter Note: Walk the group through the inspection sequence step by step. Pause at the defect-reporting point and ask what they would do if they found a critical defect. Reinforce that no one should improvise around a damaged asset or bypass lockout/tagout.

Personal Protective Equipment (PPE) Requirements

• Safety Glasses or Goggles: Wear eye protection whenever there is a risk of flying debris, dust, splashes, or contact with lubricants and cleaning agents during inspection. Select the correct lens type for the task and ensure the eyewear fits securely and remains clean enough to provide clear visibility. [8]
  • Use side protection where impact hazards exist.
  • Replace scratched or damaged lenses that reduce visibility.
  • Keep eyewear on until the inspection area is safe and clean.
• Gloves Appropriate to the Task: Use gloves that match the hazard, such as general-purpose gloves for handling sharp edges, chemical-resistant gloves for contaminated surfaces, or electrical-rated gloves where required by the task and procedure. Gloves must not create an entanglement hazard near rotating parts and should be removed when they could be pulled into moving equipment. [8]
  • Inspect gloves for tears, punctures, or contamination before use.
  • Choose gloves based on the specific hazard, not convenience.
  • Do not wear loose gloves near exposed rotating components unless the procedure allows it.
• Hard Hat: Wear head protection when there is a risk of falling objects, overhead hazards, or contact with fixed structures during inspection. Ensure the hard hat is in good condition, properly adjusted, and compatible with other PPE such as face shields or hearing protection. [8]
  • Check the shell and suspension for cracks, deformation, or wear.
  • Replace damaged hard hats immediately.
  • Use the correct class or type for the work environment.
• Safety Footwear: Wear safety footwear with slip-resistant soles and toe protection where there is a risk of dropped objects, sharp debris, slippery surfaces, or contact with equipment. Footwear should be kept clean and in good repair so it provides stable footing during access, climbing, and around oily or uneven surfaces. [8]
  • Choose footwear suitable for the surface and exposure.
  • Replace worn soles or damaged uppers that reduce traction or protection.
  • Keep laces tied and footwear secured during access and egress.

PPE supports safe inspection, but it does not make an unsafe asset safe. Workers must still use hazard assessment, engineering controls, administrative controls, and lockout/tagout where required. PPE must fit properly, be in good condition, and be inspected before use.

Real-World Example or Case Study

A worker was instructed to use a forklift that had hydraulic oil leaking into the cab from a damaged line. The worker slipped while entering the cab and injured a knee, resulting in lost work time. The incident shows why pre-use inspection matters: a visible defect, if identified early, can prevent a personal injury and avoid equipment damage. The lesson is to inspect access points, fluid leaks, and operating surfaces before use, and to remove the asset from service when a defect creates an unsafe condition. [2]

Presenter Note: Use this example to show that inspection failures are not just mechanical issues; they directly affect worker movement, access, and safe operation.

Group Discussion

Discuss the following questions:

1. What defects would require you to stop work immediately and remove the asset from service?
2. Who is authorized to inspect, isolate, and sign off on repairs for this equipment?
3. How do we make sure defects are reported, tracked, and corrected before the asset is returned to service?

Presenter Note: Encourage workers to speak from experience. Ask them to identify the most common defects on their equipment and how those defects are currently reported and corrected.

Emergency Procedures

1. If a dangerous defect or unexpected movement is discovered, stop work immediately, warn nearby workers, and move to a safe location away from the hazard zone.
2. If maintenance or repair is required, isolate the asset, apply lockout/tagout, and verify zero energy before any person approaches the danger area.
3. If an injury occurs, summon emergency assistance, provide first aid within your training, and do not restart or move the asset until the scene is controlled and released by the responsible authority.

Questions and Answers

Invite questions throughout the talk, especially about local inspection checklists, defect reporting routes, and when lockout/tagout is required. Clarify any uncertainty before work begins.

• Q: When should an asset be removed from service during inspection?

A: Remove the asset from service whenever a defect, damage, leak, missing guard, abnormal condition, or unsafe operating issue could expose workers to injury or cause equipment failure. If there is any doubt about safety, stop use and escalate the issue for review. [2] [1]

• Q: Who should perform lockout/tagout if inspection turns into maintenance?

A: Only trained and authorized employees should perform lockout/tagout. If more than one employee is involved, each person must apply their own lock and tag according to site procedure. [3] [7]

• Q: What records should be kept after an inspection?

A: Keep records that identify the asset, the inspection date, the inspector or competent person, the findings, the defect status, and the corrective action taken or required. Records should support follow-up, trend analysis, and proof that unsafe conditions were addressed. [13]

Summary

Recap of main points:

• Inspect assets before use and at the required periodic interval using the correct checklist and competent-person review.
• Identify hazards early, assess the risk, and remove unsafe equipment from service without delay.
• Use lockout/tagout whenever maintenance, cleaning, repair, or adjustment exposes workers to hazardous energy.
• Document defects, corrective actions, and return-to-service checks to protect workers and maintain asset integrity.

Action Items

Specific actions participants should take:

1. Use the inspection checklist every time and never skip steps because the asset appears to be working normally.
2. Report defects immediately and clearly identify whether the asset is safe, restricted, or out of service.
3. Stop and isolate the asset if maintenance or repair is needed, and follow lockout/tagout procedures before any work continues.
4. Verify that records are completed and that the asset is safe before it is returned to service.

Remember: Inspect it, isolate it, report it, and only return it to service when it is safe.

Report all hazards, near-misses, and incidents to your supervisor immediately.
