A tower crane is being erected on a construction site. The crane will have a maximum lifting capacity of 12 tons and a boom length of 180 feet. What certification is required before the crane can be used?
Correct Answer
C) Initial inspection and load test by qualified person
OSHA requires all cranes to receive an initial inspection and load test by a qualified person before being put into service. This ensures the crane meets safety standards and can safely handle its rated capacity.
Why This Is the Correct Answer
OSHA 29 CFR 1926.1412 mandates that all cranes must undergo an initial inspection and load test by a qualified person before being placed into service. This requirement applies regardless of crane type, capacity, or boom length. The initial inspection verifies structural integrity, proper assembly, and operational safety, while the load test confirms the crane can safely handle its rated capacity under actual working conditions.
Why the Other Options Are Wrong
Option A: Manufacturer's certificate only
A manufacturer's certificate alone is insufficient for OSHA compliance. While manufacturers provide specifications and assembly instructions, OSHA requires independent verification through inspection and testing by a qualified person at the job site.
Option B: Annual inspection by qualified person
Annual inspections are required for ongoing operations, but they do not satisfy the initial certification requirement before first use. The crane must pass both initial inspection/load test AND subsequent annual inspections.
Option D: No special certification required
This is completely incorrect as OSHA has strict certification requirements for all cranes. Operating a crane without proper initial inspection and load testing would be a serious safety violation with potential criminal liability.
Memory Technique
Think 'Before you LIFT, you must TEST' - no crane can lift loads until it passes initial inspection and load testing by a qualified person.
