How to Run a Peer Check Before Routine Work in 10 Minutes
A practical peer-check routine for supervisors who need workers to challenge routine risk before shortcuts, drift or silence become normal.

Key takeaways
- 01Use peer checks to make routine work visible before shortcuts and drift become accepted by the crew.
- 02Start with the task, control and consequence, because personal warnings rarely change behavior under production pressure.
- 03Ask one worker to challenge the plan and one worker to defend the control so silence does not look like agreement.
- 04Link the peer check to stop-work triggers, ownership and feedback, not only to a signature on a pre-task form.
- 05Apply Andreza Araujo's safety culture logic by treating peer checks as repeated decisions that reveal how the field really works.
Routine work creates a specific safety problem: people stop seeing the risk because nothing happened yesterday. The task feels familiar, the crew knows the sequence, and the supervisor may assume that experience is enough to keep exposure under control.
A peer check is a 10-minute field routine in which workers challenge each other's plan before routine work begins. It is not a motivational conversation. It is a small control that forces the team to name what could hurt someone, which barrier is supposed to prevent it, and what condition would make the job pause.
The common advice says workers should watch out for one another. That advice is decent but incomplete, because care without structure often becomes a friendly warning after the risky move has already happened. Across 25+ years leading EHS in multinational operations, Andreza Araujo has seen that routine exposure changes only when the crew has permission, language and time to challenge the plan before the first step.
This guide is written for supervisors, shift leaders and EHS managers who need a practical method for routine work such as cleaning, adjustment, material movement, manual handling, minor maintenance, line changeover and repetitive inspection. It pairs behavior with control, because safe behavior is not a personality trait. It is a repeated decision shaped by task design, pressure, supervision and what the group accepts as normal.
What you need before starting
Before running a peer check, choose a task that is familiar enough to be underestimated. The routine should be short, visible and specific, otherwise it becomes another safety talk that workers tolerate without changing the way they start the job.
You need the current procedure or work instruction, the known critical control, the planned work area, and one supervisor who can remove obstacles if the crew finds a weak condition. If the peer check discovers that the task has changed, connect it with a dynamic risk assessment routine rather than forcing the team to continue under the old plan.
Set one rule before the first conversation: challenge the work, not the person's character. James Reason's writing on latent failures is useful here because visible actions often sit on top of planning, staffing, maintenance, design and supervision conditions. A peer check should surface those conditions while the team can still correct them.
Step 1: Pick the routine task with the highest tolerance for drift
The first step is to select one task where the crew has become too comfortable. Do not start with the rare emergency job. Start with the activity that happens every shift, creates repeated exposure, and receives less attention precisely because it is normal.
Look for signs such as skipped checks, informal tool changes, workers standing in the same line of fire, repeated small jams, late isolation, unclear hand signals, or a habit of saying that everyone already knows the job. These signs matter because routine work can drift slowly while the record still looks clean.
The trap is choosing the task that is easiest to discuss instead of the task that most needs challenge. If nobody in the crew can remember the last time the method was questioned, that task is a strong candidate for the first peer check.
Step 2: State the credible harm in plain language
The second step is to name what could realistically hurt someone during the task. Avoid vague language such as be careful, pay attention or stay safe. Those phrases are too soft to guide a decision when time pressure rises.
Use task and consequence language. Say that a hand can be caught during a jam clear, a pedestrian can enter the forklift path, a worker can be struck during a lift, or a chemical splash can reach the face before the eyewash route is clear. The point is not to dramatize the work but to make the exposure visible.
This step connects with shortcut normalization, because shortcuts usually survive when the consequence has become abstract. A peer check brings the consequence back into the decision before the shortcut feels harmless.
Step 3: Ask one worker to explain the control
The third step is to ask one worker to explain the control that is supposed to prevent the credible harm. If the team cannot explain the control, the control is not ready for routine use.
For line-of-fire exposure, the control may be separation, barricading, sequencing, a spotter or a no-go position. For stored energy, it may be isolation, verification and control of residual movement. For manual handling, it may be mechanical aid, team lift, route clearing or load redesign. The peer check should name the control in a way that can be seen in the field.
In Safety Culture: From Theory to Practice, Andreza Araujo argues that culture appears in repeated decisions, not in declared values alone. When workers explain the control before the task, the site tests whether the declared system has reached the actual work.
Step 4: Ask another worker to challenge the weak point
The fourth step is to assign a second worker to challenge the plan. This person is not being negative. Their role is to protect the crew from agreement by silence.
The challenge can be simple. Ask what changed since the last time, what condition would make the control fail, what the crew usually skips when rushed, and where someone could be exposed before the supervisor notices. If the task includes contractors, new workers or a handover between shifts, ask what they may not know.
This is where peer checks differ from ordinary reminders. The crew is not only repeating the rule. It is testing whether the rule fits today's work, in this area, with this team, under this pressure.
Step 5: Define the stop-work trigger before starting
The fifth step is to define one stop-work trigger before the task begins. A trigger gives the worker language for pausing the job without needing a debate at the riskiest moment.
Examples include missing guarding, unexpected energy, blocked access, a pedestrian crossing the work zone, loss of communication, damaged PPE, wrong tool, unstable load, chemical label uncertainty or pressure to continue after a control fails. The trigger should be specific enough that workers can recognize it quickly.
If the site already uses field conversations, connect this trigger with active care conversations. The peer check happens before exposure, while the conversation during work reinforces the same trigger if conditions shift.
Step 6: Remove one obstacle immediately
The sixth step is to correct one obstacle before the crew starts. A peer check loses credibility when workers identify a problem and the supervisor tells them to continue anyway.
The obstacle may be a missing tool, poor lighting, a blocked route, an unclear hand signal, a rushed sequence, a production conflict or a control that exists on paper but is not available in the work area. Fix what can be fixed now, and escalate what needs authority beyond the crew.
Andreza Araujo's work across more than 250 cultural transformation projects points to a recurring pattern: workers learn the real culture by watching whether leaders remove obstacles or simply ask people to compensate. A peer check should reduce compensation, not make workers carry more risk with better words.
Step 7: Record only the decision that matters
The seventh step is to record the decision without turning the routine into paperwork theater. The record should show the task, the credible harm, the control, the challenge raised, the stop-work trigger and the obstacle removed or escalated.
Do not ask workers to write a long essay. A short field note is enough when it proves that the team tested the work before exposure began. If the record only says completed, it does not help the supervisor see whether the conversation had quality.
This is also why behavioral observation calibration matters. Leaders should review the quality of peer checks, not only the quantity, because high volume can hide weak conversations just as easily as low reporting can hide fear.
Step 8: Review the pattern at the end of the week
The eighth step is to review the week's peer checks for patterns. Look for repeated obstacles, repeated stop-work triggers, tasks that always need correction, crews that never challenge the plan, and supervisors who accept the form without a real conversation.
The weekly review should ask one practical question: what are workers repeatedly compensating for? If the answer is poor tools, layout, staffing, planning, maintenance, contractor interface or schedule pressure, the fix belongs above the individual worker.
Connect the findings with the supervisor rhythm described in safe behavior routines for production supervisors. Peer checks work best when they feed a leadership cadence that removes conditions, not when they sit as isolated moments in the field.
Peer check script for routine work
Use this short script until supervisors and crews can run the conversation naturally. Keep it near the work area and change the examples to match the site.
- What part of this routine task could hurt someone today?
- Which control prevents that harm, and can we see it now?
- What changed since the last time we did this work?
- What do we usually skip when the job is rushed?
- What exact condition makes us stop before continuing?
- What obstacle can we remove before the first step?
The script is intentionally small because routine work does not need another ceremony. It needs a repeatable challenge that exposes drift while the team can still choose a safer path.
What the supervisor should watch for
The supervisor should watch for silence, joking, automatic agreement, and answers that describe attitude rather than controls. Those reactions often mean the crew is treating the peer check as a compliance ritual instead of a risk conversation.
Two traps deserve attention. The first is using peer pressure to force conformity, which makes workers challenge less, not more. The second is turning every issue into a behavioral defect, although the weak point may sit in design, tools, planning or staffing. Both traps make the method look active while leaving routine exposure untouched.
When the routine works, workers start naming small deviations earlier, supervisors see repeated barriers in the work system, and EHS managers gain field evidence that can guide better controls.
