Aerial Lift Pre-Use Inspection

This inspection covers the pre-use check immediately before operating a scissor lift or boom lift. It is not the periodic mechanical inspection or thorough examination the machine also needs on its own separate cycle.

OSHA 1910.67 sets the direct operating and inspection duties for aerial lifts, while CSA B354 carries the design and safe-use detail behind the site and equipment checks the template applies.

The duty to check an aerial lift before use is close to universal in general terms, but how the check is framed, and which regime treats the lift as lifting equipment rather than mobile plant, differs by jurisdiction.

The checklist covers the mechanical and site items directly. The judgement that determines whether the inspection actually protects the operator sits in how a handful of specific answers are treated.

The template is thorough on paper. Findings tend to concern which checks were actually treated as stop-work items and which were waved through as formalities.

A boom lift passed its pre-use inspection cleanly: tyres, hydraulics, structure, guardrails, controls and alarms all scored pass. The operator was current on authorisation and had run this model before. The site conditions section was completed in under a minute, ground firm and level marked pass, overhead clearance marked pass, no overhead power lines marked pass.

The lift was working within three metres of a line that the site conditions check had marked clear, because the operator's attention that morning had been on the machine, which he knew well, rather than on the site, which had changed since the job was last worked there. The exclusion zone required for that voltage had not been set, and the near miss that followed was resolved without contact only because a second worker on the ground called it before the boom moved further.

The checklist itself is not where this fails. What slips is the site judgement made in under a minute, and the gap between an authorisation that exists and a familiarisation that is actually current.

KnowSafe

Holds the aerial lift register against operator authorisation and model familiarisation records, and blocks reissue of a lift with an open work order against it.

Ella

Flags when a site conditions section is completed unusually quickly relative to the job, and surfaces recent near misses at a location before the next lift goes up there.

KnowTrain

Tracks authorisation and model-specific familiarisation separately, so a general aerial lift ticket is never read as competence on a machine the operator has not actually run.

Pre-use inspection

The operator's check immediately before operating the lift, distinct from the scheduled mechanical inspection or thorough examination carried out on a separate cycle.

Knockout item

A checklist item whose fail result stops the lift being used regardless of how other items scored, rather than being averaged into an overall percentage.

Familiarisation

Practical competence on the specific make and model in front of the operator, distinct from a general authorisation to operate aerial lifts as a class.

Exclusion zone

The area around the lift's working envelope kept clear of unauthorised people and hazards, including the required standoff distance from overhead power lines.

Emergency lowering

The backup control, typically at ground level, used to bring the platform down if the primary platform controls fail or the operator becomes incapacitated.
