Peer Checking: Agree Before the Action

HOP skills practice • Batch 1, topic 2 of 5. A 5–10 minute toolbox talk plus time for actual field verification. One-page PDF and editable Word talk; separate supervisor and attendance forms.

What is this skill?

Peer checking pairs a performer with a prepared peer before and during a specific action. Each checks the item and instruction, they agree on the action, and the peer observes and raises a mismatch.

Why use it?

A prepared second person can notice something the performer missed. This requires task understanding, a usable view, attention and freedom to speak up; being nearby is not enough.

When should we use it?

Use it where the task process requires it, or where a prepared peer can help catch a consequential selection or action error. Agree on the exact step before starting.

Where does it apply?

At the same action point, where both people can safely identify the item and the peer can observe the step. An after-the-fact signature is not a peer check.

Learning objective

Demonstrate separate self-checks, agreement and an effective pause response before a simulated action.

Key hazards or failure points

Unprepared peer; blocked view; acting too soon; shared assumptions; reluctance to challenge; observation mistaken for condition verification.

How to use it — practical controls

• Assign a performer and prepared peer. Each checks the item and instruction before comparing conclusions. Retain the performer's self-check.
• Agree on the action, safe positions, readiness and stop signal. The peer observes the specified action and communicates any mismatch promptly.
• Confirm the action taken. Complete any separately required condition verification; peer checking does not replace independent verification or work authorization.

Verify It in the Field

• Before real work, confirm both people can see, communicate and perform their assigned roles safely. Record the actual check as required by the task.
• Practice with paper cards marked Order 31 and Order 13. Each person checks a mock instruction selecting Order 31, then agrees on the selection.
• Announce a second round with a simulated wrong selection. The peer calls the agreed pause before selection is completed; the performer stops. Discuss any missed cue.

For real work, record the control, governing source and criterion, safe method, authorized checker, actual result and time. Mark VERIFIED, HOLD/NOT VERIFIED, or N/A with a reason. A practiced skill or matching label does not demonstrate that a physical safeguard functions. Do not create exposure to complete a check.

Stop and reassess

Hold if either person is unready, loses the view or communication, or identifies a mismatch. Follow the safe response; never reach into hazardous movement to stop someone.

Toolbox talk questions

• Which exact action needs the peer's attention?
• Can either person challenge without being rushed?
• What condition still needs separate verification?

Examples across different work settings

These are original teaching examples, not operating instructions. Use paper, photographs or inert training items for practice. Change the setting to fit your team while retaining the skill steps and the applicable task requirements.

Distribution

Two prepared workers compare an order with the carton identifier before the selection is finalized. The peer watches the agreed selection. Product acceptance, loading and transport requirements remain separate.

Laboratory support

Using an inert training kit, each participant compares a supply label with a mock requisition before one selects the item. This exercise involves no chemicals, samples or clinical decisions; real technical requirements still govern.

Maintenance

Before a specified action, the performer and peer separately identify the item from the current instruction. The peer observes safely. Seeing the action occur does not establish isolation or prove the resulting condition.

Leader follow-through — improve the conditions

Give the peer enough time and task information to check. If visibility is poor or the peer is also expected to do another task, change the work arrangement before relying on the check. Thank people for identifying a mismatch, regardless of rank.

Short supervisor field check

• Performer and peer have task-specific preparation and role authority.
• Each checks the item and instruction before agreeing on the action.
• Safe view, reliable communication and readiness are demonstrated.
• Paper mismatch is caught and the performer responds to the pause signal.
• Actual check is recorded when performed; required condition verification remains.

Use the separate supervisor sheet to retain evidence, open items, correction owner, recheck result and required restart authority. Keep task-specific permits, inspections and technical decisions in their established process.

Attendance and follow-through

Use the separate attendance sheet for participants, roles, questions, actions and rebriefs. Attendance does not establish competence, verify a control or authorize work. Keep completed records private under employer procedures.
