DG Exclusion Zones and Barricading 3

Question 1

When must a dogman establish the exclusion zone relative to the start of crane operations?

Accepted Answer

Before any crane movement begins, including during crane setup

Answer

The exclusion zone must be established before any crane movement begins because counterweights, booms, and other components during setup can also pose hazards to nearby workers.

Question 2

What does the term 'fall zone' mean in the context of exclusion zones for lifting operations?

Accepted Answer

The area that could be struck by a falling load or failed lifting component

Answer

The fall zone is the area that could be struck if a load, sling, or other lifting component were to fail and fall, and it must be kept clear of all personnel.

Question 3

When a crane lifts materials near an elevated work platform, how must the exclusion zone account for workers at height?

Accepted Answer

The exclusion zone must encompass the elevated platform area when a load passes nearby

Answer

When loads are lifted near elevated work platforms, those platforms must be included in the exclusion zone or workers evacuated, as a swinging load can strike elevated workers.

Question 4

Under the Work Health and Safety Act, what is the potential consequence for a PCBU that fails to ensure exclusion zones are properly established during crane operations?

Accepted Answer

Significant financial penalties and potential imprisonment for gross negligence causing death or serious injury

Answer

Under WHS legislation, PCBUs who breach their duty of care regarding exclusion zones face substantial financial penalties and, in cases of gross negligence causing death or serious injury, potential imprisonment.

Question 5

During a lift, the dogman notices the load is swinging more than expected beyond the planned exclusion zone. What is the correct course of action?

Accepted Answer

Stop the lift, reassess the exclusion zone size, extend it if necessary, then resume

Answer

If conditions change during a lift, the dogman must stop operations, reassess the situation, extend the exclusion zone as required, and only resume when it is safe to do so.
