THE JOB

Flying a corner, infill or nontypical table. Method: GOSPEL-SWP-029 plus 028. BC Crane Safety: special handling plan.

WHO IS EXPOSED

  • Same as a typical cycle
  • Whoever the special plan names as extra tag line or spotter
  • The engineer if the plan is missing or the table changed

A JHA names what can hurt someone and how that risk is controlled. It is not the procedure. Do the work to the matching SWP. WorkSafeBC does not prescribe a JHA form — the Workers Compensation Act s. 21(2)(b) requires workers to be made aware of known or reasonably foreseeable hazards. This is how GOSPEL does that for this job.

HAZARDS AND RISK

Task is the work being analysed — not a procedure to follow. Controls follow the hierarchy: eliminate, substitute, engineer, administer, PPE last. The badge is how bad this task going wrong is in this job. Extreme is the killer with no recovery. High is serious injury or a dropped load you still have a chance to stop. Moderate is lost time or a plan that failed. Low is first aid.

RESIDUAL RISK

Even with a special plan, a nontypical table can spin when it leaves the slab. Residual is held by slower holds and by refusing the typical SJP — not by ‘we’ve flown corners on this job.’

THE JOB DOES NOT PROCEED IF

  • No special engineered handling plan at the lift
  • Crew cannot say why this table is not typical
  • Sling geometry copied from a typical table
  • Anyone calling it close enough to typical

PPE — LAST LINE

  • Hard hat
  • CSA-grade footwear
  • High-visibility clothing
  • Eye protection
  • Task-rated gloves
  • Hearing protection where required
  • Fall protection where the work exposes a fall
