Boom-Supported Lifts Electrocutions – almost all due to overhead power lines Falls 1/2 of electrocutions involved body contact with overhead power linesOne-third involved overhead power lines contacting lift booms orbuckets1/2 of fatal falls involved ejection from the bucket after worker or liftswas struck by vehicles, cranes or objects.1/6 occurred while transferring to or from the bucket at a heightCollapses/tipovers 2/5 of deaths involved collapse of boomAlmost one-third were due to tipovers.1/4 involved collapses of bucket
Boom-Supported Lifts (Cont.) Caught in /between Most involved the worker getting caught between the bucket edgeand a roof joist or beam.Struck by/against Mostly involved workers being struck by collapsing materials,girders, etc.
Scissor Lifts Falls 1/5 of deaths involved ejections, after being struck by objectCause of fall unknown in 3/5 of deathsOther causes included removal of chains, standing on orleaning over railingsTipovers Caused almost 1/3 of scissor lift deathsMostly while elevated over 15 feet1/4 of tipovers occurred where lift hit a hole or curb whilemovingElectrocutions 1/2 involved overhead power lines
Renting an Aerial Lift Get maintenance history of aerial liftGet operator’s manual and maintenance manual (if separate)Ensure a detailed maintenance check is done before rentalMake sure operator controls are easily accessible and properlymarked
Operator Training Training must be done by a qualified person experiencedwith the particular lift modelTraining must include:¾¾¾¾¾Nature of electrical, fall, and other hazards involved in operatingliftPrecautions for dealing with hazardsRated load capacity for the lift (including workers, tools,materials, bucket liner, etc.)Manufacturer requirements, as outlined in operator manualDemonstration of skill and knowledge in actual operation of theaerial lift
Qualified Person Definition OSHA 1926.450(b)A qualified person . by extensive knowledge,training, and experience can .solve .problemsrelated to the subject matter .
Maintenance Requirements Training of mechanics should be done by qualified personexperienced with lift modelMaintenance should include:¾¾¾ Knowledge of manufacturer’s maintenance requirementsFrequent inspections of aerial lift by qualified mechanicAt least annual detailed inspections by qualified mechanicInsulated aerial lifts have special electrical testrequirementsDe-energize and lockout/tagout aerial lift beforeconducting maintenance and repairs
Before Operating Aerial Lifts Do not modify aerial lift without written permissionCheck safety devices, operating controls before each useCheck area in which aerial lift will be used for:¾¾¾¾¾ Level surface (Do not exceed manufacturer slope recommendations)Holes, drop-offs, bumps, debris, etc.Overhead obstructions and overhead power linesStable surfaceOther hazardsSet outriggers, brakes, wheel chocks
Preventing Electrocutions Non-electrical workers must stay at least 10 feet awayfrom overhead power lines.Electrical workers must de-energize/insulate power lines oruse proper PPE/equipment.Use insulated buckets near overhead power linesRegularly check insulation on buckets
Preventing Tip-Overs Do not exceed manufacturer rated load capacity limitsDo not travel to job location with lift in elevated position.Set up proper work zone protection when working neartrafficPositioning of lifts¾¾¾¾¾ Do not drive near drop-offs or holes.Do not raise platform on uneven or soft surfaces.Do not drive onto uneven or soft surfaces when elevated.Do not raise platform on slope or drive onto slope when elevated.Do not raise platform in windy or gusty conditions.Avoid excessive horizontal forces when working onelevated scissor lifts
Fall Protection OSHA regulates aerial lifts as scaffolds¾¾¾ 1926.453 Aerial Lifts only applies to bucket trucksFall protection is required (full body harness with lanyard or body beltwith 2-foot lanyard as restraint device)OSHA does not require harnesses and lanyards on other boom lifts andscissor lifts if there are guardrailsFall arrest systems (harness plus lanyard to stop a fall)¾Can tip over some boom lifts and scissor lifts due to fall stopping force Fall restraint systems intended to prevent falls are preferred¾ e.g. Full body harness plus lanyard designed for size of lift platformAlways close entrance chains or doorsStand on floor of bucket or lift platform¾Do not climb on or lean over guardrails
