The thought of an OSHA Compliance Office visiting a construction site may make some cringe.
OSHA released a ‘directive for enforcing requirements of the Cranes and Derricks in Construction standard.’ The purpose of the directive is to give OSHA personnel a basis on how to conduct their inspections at construction sites when equipment covered by Subpart CC are present.
The items outlined below are just the minimum a Compliance Office follows during their inspection. The officer can include items in the inspection from other applicable requirements if the reason for the inspection is a fatality, compliant/referral inspection, or if a hazardous condition is present.
- Are ground conditions adequate, including support/foundation, matting, cribbing, blocking, etc?
- Is there visibly apparent need for repairs of equipment?
- Are nearby power lines energized; what is the voltage; what is the crane’s working area; and what are the encroachment prevention procedures?
- Is a signal person used and do they have documentation of qualification, electronic or physical?
- Is the qualified signal person the one communicating with the operator?
- Are lift plans being followed, if used?
- If hoisting personnel, who determined it was necessary?
- Are meetings being conducting for working near power lines, A/D work or hoisting?
- Is all available rigging equipment compliant?
- Are load charts and OEM manual’s available for the specific equipment used?
- Is the operator qualified, trained and competent?
- Are equipment and wire rope inspections being conducted; by whom; and are they qualified?
- Are safety devices and operational aids functioning?
- Are there any visual deficiencies of hoisting equipment, components and load line?
- How is weight of load determined?
- Are qualified riggers being used for A/D work and when in the fall zone?
- Who is the A/D Director and are they present?
- Are oilers and mechanics qualified; are they communicating with the operator; and are...
Sidewalks are built for pedestrian traffic, not to support the weight of an aerial lift. The wheels of this aerial lift exert hundreds of pounds per square inch of weight on the ground beneath it.
This operator chose to operate the aerial lift on a sidewalk which also contains service covers. Obviously, these service covers are rated less than the sidewalk. The operator drove over the sidewalk cover causing it to crumble and ultimately triggering the toppling of this aerial lift.
The condition of the occupants of this aerial lift is unknown; however, the most common cause of fatalities in aerial lift accidents is turnover.
Handling a load with one forklift may not be complicated, but handling a load with two forklifts can be very complicated. This job required two forklifts and a scissor lift working together in close proximity to each other. It would seem simple enough to unhook and lower this dragster to the floor, but the forklifts don’t work in unison. The difference in the lowering speed of each forklift could cause the dragster to fall from the forks.
The task would require the forklifts to be positioned under the dragster in a manner that would prevent damaging as well as balancing the vehicle. At the direction of a signalperson, the forklifts would raise the dragster to take the weight of the hangers. Then, it would be disconnected. Finally, the signal person would observe and control the descent of each forklift.
