What is the key responsibility of a competent person on a construction site?

The key responsibility of a competent person on a construction site is to identify and address hazardous conditions promptly. A competent person is defined by OSHA as someone who is capable of identifying existing and predictable hazards in the surroundings or working conditions that are unsanitary, hazardous, or dangerous to employees. This individual must have the authority to take prompt corrective measures to eliminate these hazards. This function is crucial for maintaining a safe working environment and preventing accidents or injuries on the job site. Recognizing risks and addressing them proactively helps ensure the health and safety of all workers present, making it an essential duty for anyone in that role.

The other responsibilities mentioned in the other options play important roles in construction project management, but they do not encapsulate the primary duty of ensuring a safe work environment as defined for a competent person. Managing financial aspects, ensuring compliance with zoning laws, and supervising personnel are critical components of construction management but do not directly correlate to the core responsibility of hazard identification and risk management.
