Supervisor Improvement Action Verification Interview Checklist

Meeting with supervisor to verify corrective measures
Checklist and Recording Method

The meeting to verify corrective measures is not a forum to ask the person in charge, "Is it complete?" It is a brief on-site verification to determine the next steps by confirming whether the planned measures were actually applied at the site, whether the workers understand the changed methods, and what remaining risks exist.

📌 Key points to check first

Supervisors participate in the process of verifying the safety and health status of equipment related to the work they direct and supervise, identifying hazardous factors in risk assessments, and implementing corrective measures. Therefore, their role does not end with merely confirming that corrective measures have been documented. They must verify whether actual work methods and equipment conditions have changed.

It is practically useful to design interviews as a procedure to verify the 'completed' mark on the Improvement Action Implementation Management Log. You should confirm the fact of implementation and supporting evidence with the person in charge, verify with the workers whether they understand and are using the changes, and confirm with the safety and health manager whether the risk level has actually been reduced. The key is not to judge completion based on the answer of just one person.

While existing comprehensive risk assessment guides explain the entire assessment procedure, this article focuses on how supervisors interview and determine the completion of measures whose improvement deadlines have arrived. The purpose is to connect existing assessment checklists and action logs with on-site questions, rather than creating new checklists.

Materials to prepare before the interview

Before the interview, prepare the evaluation checklist, list of corrective actions, person in charge and deadline, photos taken before the action, purchasing, repair, and training records, and the revised work standard as a single set. If you ask questions based only on the title of the action, it is difficult to verify whether it has been completed. You must first read what the original risk factor was and what state was determined to be completed.

For visually verifiable measures, such as equipment improvements, the site location and equipment number are indicated; for measures requiring actionable verification, such as training or procedure changes, the training subjects and actual execution scenes are defined. If the measures were performed by a subcontractor, the scope of verification by the prime contractor's representative, the subcontractor's supervisor, and the actual worker is also distinguished.

💬 Step 1: Questions to ask the person in charge of the action

The first question should be "What has changed compared to the original completion criteria?" rather than "What was done?" If the person in charge cannot explain the actions taken in detail, it is possible that the task was processed as completed simply by finalizing the purchase or conducting training. Check the installation location, target audience, execution date, and scope of non-compliance in that order.

If only a portion has been completed due to budget or production schedules, distinguish between full completion and partial completion. Do not merely record the reason for non-completion; you must also identify temporary safety measures, departments requiring additional support, new deadlines, and reconfirmers to ensure the ledger leads to the next step.

👷 Step 2: Questions to confirm with the worker

Even if the person in charge of the action states that it has been completed, on-site implementation is not finished if the worker is unaware of the changes or works in a roundabout way. Ask workers about their actual actions rather than the terminology in the evaluation document. Questions that allow them to describe their experiences, such as "What has changed?", "What do you check before starting work?", and "When do you feel uncomfortable or when does it become dangerous again?", are effective.

It is advisable not to limit the interview subjects to just one person recommended by the person in charge of the action. Including individuals with different working conditions—such as day/night shifts, skilled/new employees, or in-house employees/subcontractors—can help identify measures that are not functioning during specific time periods or instances of training omissions. The responses are used as data to assess the effectiveness of the measures, not as individual evaluations.

🔎 Step 3: Compare evidence and status on-site

Compare interview responses with the actual site conditions to the extent possible. Verify that photos are taken at the correct time and location, that protective devices are functioning, and that pathways and signage remain in place even when shifts change. For training measures, check not only the attendance list but also whether workers explain key protocols and actually perform them.

You must also check if any new risks have emerged during the verification process. Reducing one risk may increase another, such as when the installation of protective covers makes cleaning more difficult or when attempts to lighten the load lengthen movement paths. In such cases, rather than declaring existing measures a failure, these should be registered as additional risk factors and priorities reassessed.

📊 Determining Completion, Partial Completion, and Incompleteness

For a completion determination, proof of execution and verification of effectiveness must be separated. Records of purchase, installation, and training serve as the basis for 'execution,' while the reduction in risk levels and changes in worker behavior serve as the basis for 'effectiveness.' Both must be verified for the determination to be completed.

Partial completion is not an indication of failure, but rather a state for transparently managing the remaining scope. However, if critical protective measures are missing from high-risk operations, do not maintain the status as partial completion for an extended period; instead, immediately review protective measures such as work suspension, access restriction, or alternative operations.

Sample verification must also be recorded. Even with the same measure, the reliability of the assessment varies depending on whether only one piece of equipment and one worker were verified, or whether the entire facility and shift were verified. Record the verified equipment, processes, time periods, and worker scope in the interview log, and separate any unverified scope for the next inspection. In particular, if a visit was made only during the day, you must separately verify whether the night shift uses the same protective devices and procedures.

A maintenance verification date is set even after the completion judgment. This is because protective devices may not be returned to their original positions after cleaning or maintenance, or work procedures modified by new personnel may be interrupted. High-risk measures are linked to the schedule for the next巡回 inspection or ad-hoc risk assessment, and for measures that are repeatedly reverted, higher-level countermeasures such as design, procurement, and work plans are reviewed rather than relying on individual caution. The results of the re-verification are linked to the original measure number to be recorded in the history and reflected in the training for the next shift and new personnel.

📝 This is how we record the interview.

The record should include the interview date, location, verifier, action number, original risk factor, details of implementation, worker verification results, on-site evidence, residual risk, assessment, subsequent person in charge, and deadline. Using only expressions like "no abnormalities" makes it difficult to reconstruct what was verified. It is advisable to separate facts from judgments when writing.

For example, under Facts, write 'September 7: Installation of protective cover on Press No. 2 and verification of interlock operation; one day and one night worker can explain the change procedure,' and under Judgment, write 'Reduced possibility of pinching access; retraining on power cutoff procedures during cleaning is required.' If you link to the supporting file name or document location, the next inspector can verify it immediately.

⚠️ Common errors

First, there is the error of marking tasks as completed based solely on purchase orders or training announcements. Second, there is the error of omitting worker verification after hearing only the response from a single supervisor. Third, there is the error of recording only the reason for the delay without setting temporary measures or a new deadline. Fourth, there is the error of postponing high-risk incomplete items by checking all measures at the same frequency.

You should also avoid treating interviews like performance evaluations. Measures will only be improved when workers can honestly articulate their inconveniences and detours. Rather than assigning individual responsibility, identify which factors—such as equipment, procedures, training, personnel, or schedules—are hindering execution, and separate the areas where the organization needs to provide support.

When operating on a short basis, verify the initial risks and completion criteria for 3 minutes, listen to explanations from the manager and workers for 5 minutes, compare the site with supporting documents for 5 minutes, and agree on the judgment and subsequent deadlines for 2 minutes. High-risk items or items with conflicting opinions are transferred to a separate on-site inspection.
