Occupational Safety and Health Regulations and Standards for Hoisting Equipment

What the exam tests

This domain asks you to separate legal minimums from consensus standards and to place duties on the right role. Expect questions on OSHA 29 CFR 1926 Subpart CC scope, operator qualification, competent and qualified persons, and Connecticut licensing. The exam is not asking you to recite section numbers; it asks who must do what, and which document controls when two rules differ.

Core rules

  • Subpart CC applies to power-operated equipment used in construction that can hoist, lower, and horizontally move a suspended load. It covers mobile cranes, tower cranes, derricks, and some articulating booms.
  • The employer must ensure operators are trained, certified by an accredited certifying body, and evaluated by the employer. Certification alone is not the whole qualification.
  • A competent person determines ground conditions and inspections within their knowledge; a qualified person performs design, engineering, and complex repairs.
  • The manufacturer's operating manual and load chart are controlling for that machine. OSHA sets the floor; a stricter manual, site rule, or Connecticut license condition controls.
  • ASME B30.5 (mobile cranes), B30.9 (slings), and B30.20 (below-the-hook devices) are consensus standards. They become enforceable through OSHA references, contracts, state law, or the manufacturer's manual.

Worked example

An employer has an operator with a valid NCCCO certification, no employer evaluation, and a state crane license. Is the operator fully qualified under Subpart CC? No. Certification is one element; the employer still must document training and a practical evaluation. The state license may satisfy a separate Connecticut requirement, but it does not replace the federal qualification chain. If the manufacturer's chart limits the crane to 12,000 lb at the planned radius and the site plan says 15,000 lb is acceptable, the chart controls.

Traps that cost marks

  • Treating a state license or a certification card as the entire OSHA qualification.
  • Mixing up competent person and qualified person.
  • Assuming ASME standards are automatically law everywhere.
  • Using a generic capacity when the manufacturer's chart has a lower limit for the configuration.
