Findings of Joint Ops Woodpecker
on 28 July 2010 Workers carrying out tree-pruning activities in man-bucket
were provided with necessary safety equipment (eg safety
harness, safety gloves, glasses etc).
All the lorry crane operators checked had undergone either a
structured training course or OJT.
Operators had also extended the outriggers of the lorry cranes
to ensure stability.
Contractors were generally aware of the need to demarcate the
work zone through the placement of appropriate cones,
barriers and warning signages, as stipulated in LTA's Code of
Practices for Traffic Control at Work Zone. However there
were sites inspected where the cones, barriers were found to
have been placed too close to the work area.
Some sites inspected did not conduct RA implement a PTW for
lifting operations involving lorry cranes.
