For before and after use inspections, the visual inspection step is generally sufficient. For periodic inspections, you should undertake the entire process. After incident inspections are detailed further below:

1. Visual Inspection

Begin with a comprehensive visual check of the entire tool. Look for signs of physical damage, such as cracks in the housing, damage to the power cord, or frayed wires. Ensure all safety guards are intact and securely in place. Check for any loose parts or screws that could impact the tool's operation.

2. Check for Modifications

Verify that the tool has not been altered in any unauthorised manner. Unauthorised modifications can compromise the tool's integrity and safety features, potentially leading to accidents.

3. Test Safety Features

Ensure that all safety features, such as emergency stop buttons, safety switches, and lock-off controls, are in proper working order. These features are vital for preventing accidents in unexpected situations.

4. Inspect Moving Parts

Check all moving parts to ensure they move smoothly without unnecessary resistance or noise. Follow the manufacturer's specifications to lubricate these parts appropriately, maintaining optimal performance and extending the tool's lifespan.

5. Electrical Safety

For electric power tools, use a multimeter to check the insulation resistance and ensure there is no leakage current. This step is crucial for preventing electric shocks.

6. Battery Inspection (for cordless tools)

Inspect the battery pack for any signs of damage or leakage. Test the battery's voltage and capacity to confirm it meets the manufacturer's specifications. A deteriorating battery can compromise the tool's performance and safety.

7. Functional Test

Conduct a functional test by operating the tool in a safe, controlled setting. This test should confirm that the tool functions as intended under load conditions. Listen for any unusual sounds or vibrations, indicating potential internal issues.

For added safety, there are some additional checks that you should make if applicable to the tool and work task:

8. PPE Compatibility Check

Assess whether the tool can be operated safely and effectively when you are wearing personal protective equipment (PPE). Some tools may require specific handling techniques or adjustments to be used safely with gloves, goggles, or other protective gear.

9. PPE Requirement Assessment

Determine if the use of the tool necessitates specific PPE to prevent harm. This includes evaluating risks such as flying debris, dust, or noise that could require the use of safety glasses, dust masks, or ear protection. Ensuring that both the tool and the task at hand are evaluated for PPE requirements is essential for safety.

After Incident Inspections

If a power tool is involved in an incident or accident, it must undergo a thorough inspection before being put back into use. This examination should identify any potential damage caused by the incident and assess whether the tool remains safe and operational. Depending on the severity of the incident, consider consulting a professional for a detailed evaluation.

In addition to performing the inspection, you also need to document it for later review. If a tool is in working condition, documenting when the inspection was performed will allow for the next inspection and/or maintenanace date to be set based on the expected use of the tool. If the tool is not in working condition, documenting it is necessary to ensure the tool is removed from service and sent for repair or disposal.

Here is an example of a power tool inspection that has been completed using a power tool inspection checklist:
