Erectors and dismantlers are workers whose principal activity involves assembling and disassembling scaffolding before other work can commence, and after that work, or a portion of it, has been completed.

Training and Competent Person Requirements

OSHA requires employers to provide training by a competent person to each employee who is involved in erecting and/or disassembling a scaffold. A competent person is defined as one who:

  • Is capable of identifying existing and predictable hazards, and
  • Has authorization to take prompt corrective measures to eliminate them.

Requirements for Designing and Constructing Scaffolds

Scaffolds must be designed by a qualified person and be constructed and loaded in accordance with that design. OSHA defines a qualified person as one who:

  • Possesses a recognized degree, certificate, or professional standing; or
  • Has extensive knowledge, training and experience; and therefore,
  • Can solve or resolve problems related to the work or the project.

A qualified person must do adequate preplanning to assure the safe erection and use of the scaffold.

Preplanning includes:

  • Determining the type of scaffold necessary for the job,
  • Determining the maximum load of the scaffold,
  • Assuring a good foundation, and
  • Avoiding electrical hazards.
