Which of the following would be an example of Due Diligence?

The answer that exemplifies Due Diligence best is the documentation of safety training sessions. Due diligence refers to the efforts made to ensure safety and compliance within a workplace, which often involves keeping comprehensive records of training, safety checks, and other preventative measures.

By documenting safety training sessions, you create a systemic approach to ensuring that all personnel are educated on safety protocols and procedures. This record can serve as evidence that the contractor has taken all necessary steps to protect workers, which can be critical in the event of an incident or regulatory inquiry. It demonstrates a commitment not just to compliance, but to fostering a culture of safety, which is fundamental to maintaining a safe work environment.

Conducting routine equipment checks also contributes to due diligence, as it ensures that machinery is functioning properly and safely, but documentation of training is a proactive measure that encompasses not just the equipment, but the people operating it. This holistic approach is vital for showing an organization's dedication to safety and compliance.
