- Each crane must have its own dedicated signal person
- The employer must develop a plan to prevent collision or contact (Correct answer)
- All cranes must stop operations simultaneously when loads swing near each other
- A licensed surveyor must mark the working radii of each crane
Correct answer: The employer must develop a plan to prevent collision or contact
When multiple cranes work in proximity, OSHA requires the employer to develop a plan to prevent collision or contact between cranes and their loads.
Question 2: OSHA's crane standard requires that a trial lift be performed when using a crane under certain conditions. Which scenario requires a trial lift?
- Every lift over 75% of the crane's rated capacity
- Every lift regardless of weight
- Any lift of a person in a personnel platform (Correct answer)
- Any lift where a new rigging configuration is used
Correct answer: Any lift of a person in a personnel platform
OSHA 29 CFR 1926.1431 requires a trial lift before hoisting personnel in a personnel platform to verify equipment function and rigging integrity.
Question 3: According to OSHA, what must a rigger do when the rated capacity of a hook is not legible on the equipment?
- Estimate the capacity based on hook size
- Remove the hook from service immediately (Correct answer)
- Contact the manufacturer for capacity information before use
- Use a 50% reduction factor for all lifts with that hook
Correct answer: Remove the hook from service immediately
When the rated capacity of a hook is not legible, OSHA requires it to be removed from service because the load limit cannot be verified.
Question 4: Under OSHA Subpart CC, what is the employer's obligation when a crane operator reports a safety concern about continuing an operation?
- The operator must continue unless a supervisor agrees the concern is valid
- The employer must address the concern before operations resume (Correct answer)
- The concern must be submitted in writing before any work stoppage
- Operations may continue at reduced load capacity while the concern is reviewed
Correct answer: The employer must address the concern before operations resume
OSHA requires employers to address safety concerns raised by crane operators before operations resume, protecting the operator's right to refuse unsafe work.
Question 5: Under 29 CFR 1926.1424, what is the employer required to establish to prevent employees from being injured by unintended equipment movement?
- A spotting procedure
- A work zone with established control measures (Correct answer)
- Mandatory hard hat and high-visibility vest requirements
- A minimum 25-foot exclusion zone around all crane operations
Correct answer: A work zone with established control measures
29 CFR 1926.1424 requires employers to establish a work zone with control measures to prevent employees from being struck by unintended crane or load movement.
Question 6: According to OSHA, when must a crane's annual inspection be performed by?
- A qualified person (Correct answer)
- A third-party ASME-certified inspector
- A competent person with crane manufacturer training
- Any employee who has completed a NCCCO course
Correct answer: A qualified person
OSHA 29 CFR 1926.1412 requires that the annual inspection be performed by a qualified person, meaning someone with specific knowledge and training.
Question 7: What action must be taken under OSHA standards if a crane is found to have a safety defect during inspection?
- The defect must be tagged and repairs completed within 30 days
- The crane must be taken out of service until the defect is corrected (Correct answer)
- Operations may continue at 50% rated capacity until repairs are made
- The defect must be reported to OSHA within 24 hours
Correct answer: The crane must be taken out of service until the defect is corrected
OSHA requires that cranes with safety defects be taken out of service immediately and not returned to service until the defect is corrected.
