The pre-task hazard assessment: filling the card so it changes the work
The mechanical crew's card repeats yesterday's ductwork task, but a new trench now affects the planned equipment route. The previous control wording does not answer today's condition. Before work starts, the crew needs a received assessment and workable route, not another copy of the old five boxes.
Make the card describe this task, its actual location and the controls required by the site's process. CCOHS job-safety analysis breaks work into steps, identifies hazards, determines controls and communicates the result. A short field card should connect to that assessed basis rather than pretend to contain every technical method. The signature is not equipment acceptance, ground-capacity evidence or permission to proceed with a missing control.
Connect the task, changed condition and receiving decision
- Identify the real task sequence. Review preparation, access, the operation and completion with the people doing the work. Use current task references and suitable observation or discussion. Include adjacent activity and what changed since the earlier assessment. Do not approach a hazardous area simply to fill a card or make the sequence so broad that important steps disappear.
- Locate hazards and the needed controls. Connect each relevant condition to its affected step and existing assessed procedure. Ask the crew about overlooked interfaces. Have appropriate qualified personnel address a missing method or technical limit. Writing be careful, wear PPE or avoid trench is not a complete route or an assessment of whether the equipment can use the available ground.
- Receive implementation before relying on it. Identify who provides each control, the actual verification and unresolved conditions. Check that necessary protection and instructions are in place through their real process before the affected work proceeds. Preserve separate equipment, access and operator requirements. A proposed alternative route remains conditional until the appropriate assessment and receiving checks occur.
- Update changes and communicate the status. Revisit the card and its supporting assessment when equipment, crew, environment or adjacent work changes. Explain the received arrangement and actual stop or escalation route to affected workers. Retain versions and unresolved limits as required. Do not overwrite a concern to make the current card look complete or wait until tomorrow to record today's changed condition.
Common mistakes
- Copying yesterday's card without checking changed conditions.
- Using a vague caution instead of an assessed control.
- Treating a proposed route as verified implementation.
- Deleting an unresolved concern when updating the form.
Checklist
The actual task card connects
- Current sequence, location and supporting references.
- Located hazards, interfaces and changed conditions.
- Assessed controls and their implementation owners.
- Actual verification and unresolved limits.
- Worker communication and a change-response route.
Check your understanding
The card says avoid the trench, but the alternative ground has not been assessed for the equipment. Can movement begin?
