Intervention 1 Launch of Joint Ops

Woodpecker on 28 July A Joint Ops codenamed Operation

Woodpecker conducted on 28 July

Ops covered 15 worksites on publicroads island-wide

Ops aimed to reinforce safety

guidelines for works on public roads

and to allow the participatingagencies to garner sense of the level

of safety awareness and compliance

to safety standards

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.

Lorry Cranes on Public Roads

Circular intended to remind

employers on common hazards

involved in such works and

preventive measures which included

the following:

Risks due to Traffic Movement

Risks involved in Operation of

Lorry Cranes Risks due to Working at Heights

Risks due to Contact with

Overhead Cables and Structures
