DG Exclusion Zones and Barricading 2

Question 1

When determining the size of an exclusion zone, which factor is the MOST critical consideration?

Accepted Answer

The potential swing radius and fall zone of the load

Answer

The potential swing radius and fall zone define the area that could be struck if control of the load is lost, making them the primary factors in sizing an exclusion zone.

Question 2

When performing a lift near a live road or public area, what additional control measure is typically required beyond standard exclusion zones?

Accepted Answer

Obtaining a permit and implementing traffic management measures

Answer

Lifting over or near public areas typically requires a permit to work, a formal lift plan, and traffic management measures to protect members of the public.

Question 3

How must the exclusion zone be managed when a crane is slewing (rotating) with a suspended load?

Accepted Answer

The exclusion zone must encompass the entire slewing arc of the crane and load

Answer

During slewing, the load travels through an arc, so the exclusion zone must cover the entire path of the crane's rotation to protect all workers in the vicinity.

Question 4

What information about exclusion zones must be included in a formal lift plan?

Accepted Answer

Location, size, entry/exit points, and the responsible persons for the exclusion zone

Answer

A formal lift plan must document the size and location of exclusion zones, designated entry and exit points, and who is responsible for establishing and maintaining them.

Question 5

During a long-duration lift where a load is held suspended while work is performed underneath, what must the dogman ensure?

Accepted Answer

The exclusion zone must be maintained for the entire duration the load remains suspended

Answer

The exclusion zone must remain in place for the entire duration that the load is suspended, as the falling load hazard exists at any time the load is off the ground.
