NCCCO Crane Operator Access, Egress, and Fall Protection

Question 1

OSHA 1926.1423 requires that employees maintain how many points of contact when climbing on a crane?

Accepted Answer

Three points at all times

Answer

OSHA 1926.1423(b) requires employees to maintain three-point contact (two hands and one foot, or two feet and one hand) whenever climbing on a crane. If one limb slips, two secure points of contact remain to prevent a fall.

Question 2

Under OSHA 1926.1423, which of the following is explicitly prohibited while climbing a crane ladder?

Accepted Answer

Carrying objects in the hands while climbing

Answer

OSHA 1926.1423(b) prohibits carrying objects in the hands while climbing because it prevents the employee from maintaining three-point contact. Tools and equipment must be carried in tool belts, pouches, or hoisted separately.

Question 3

At what height above a lower level does OSHA 1926 Subpart M require fall protection for construction employees working on crane structures?

Accepted Answer

6 feet

Answer

OSHA 1926 Subpart M requires fall protection at 6 feet or more above a lower level for construction activities, including work on crane platforms, walkways, and structural components. This threshold differs from the general industry standard of 4 feet under 1910.

Question 4

What is the key operational difference between a fall restraint system and a fall arrest system?

Accepted Answer

A fall restraint system prevents the worker from reaching the fall edge; a fall arrest system stops a worker in free fall after a fall begins

Answer

A fall restraint system uses a lanyard sized so the worker physically cannot reach the fall hazard — the fall never starts. A fall arrest system allows a fall to begin and then arrests (stops) it before the worker strikes a lower level. Both require full-body harnesses in construction environments.

Question 5

According to OSHA 1926.1423, when an employee must climb a crane ladder that has no cage, well, or integral ladder safety system, what is required?

Accepted Answer

A personal fall arrest system must be used

Answer

OSHA 1926.1423(c) requires use of a personal fall arrest system when the crane ladder is not equipped with a cage, well, or other integral fall protection. The system must include a full-body harness, energy-absorbing lanyard, and compatible anchorage point.
