This is a guide to assist in meeting the requirements of paragraph 211(2)(a) of the General Regulation 91-191 under the Occupational Health and Safety (OHS) Act. The checklists provided may not be inclusive for all types of hoisting apparatuses. For a complete checklist of the unit to be inspected, please consult the manufacturer’s specifications.

WorkSafeNB has developed separate logbooks and checklists for mobile cranes and overhead cranes. These logbooks are available by contacting any WorkSafeNB office.

Daily / Shift InspectionHoisting Apparatus Inspection Requirements

There are many manufacturers of hoisting equipment. These hoists all operate on basically the same principletofacilitatematerialhandlinginshops,factoriesandheavyworkareas.Commonfaultsencounteredwithhoistsareunsafecablesorchains,faultybrakesanddefectivelimitswitches.Underthe OHS Act, paragraph 211(2)(a) of General Regulation 91-191 requires an operator to inspect a hoisting apparatus before it is put into use at the beginning of the shift (daily) and record the results in a logbook, as specified in subsection 210(3) of Regulation 91-191.

Annual InspectionIn addition to the daily inspection, subsection 210.01(1) requires an annual inspection of the hoisting apparatusbyacompetentpersonwhocertifiesinwritingthattheapparatusmeetsthemanufacturer’sspecifications.

Theresultsoftheannual/periodicinspection,includingrepairs,adjustmentsandotherfindingsshallbe included in the logbook and made available to an officer upon request.

General Regulation 91-191 defines competent as:

(b) knowledgeableabouttheprovisionsoftheAct and the regulations that apply to the assigned work,and

(c) knowledgeableaboutpotentialoractualdangertohealthorsafetyconnectedwiththeassigned work.
