Final answer:
A competent person must be available to supervise scaffold construction or movement to ensure workplace safety and OSHA compliance.
Step-by-step explanation:
A competent person must be available to direct workers who are constructing or moving scaffolds. According to OSHA standards, a competent person is defined as one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them. In the context of scaffold construction, the competent person would be responsible for ensuring that the scaffolds are built and moved in accordance with safety regulations, potentially preventing accidents and injuries.
Employers must ensure that a competent person is always available when scaffolding work is being performed. This individual plays a critical role in supervising and ensuring the safety of workers, as well as compliance with OSHA's fall protection and other workplace safety standards.
