What is a directly observed safety measure during drilling?

Regular safety training for all personnel on site represents a directly observed safety measure during drilling because it emphasizes the importance of equipping the drill team with the knowledge and skills necessary to identify and mitigate hazards. This training is conducted on-site, making it an active and observable part of the workflow, ensuring that all team members are aware of current safety protocols, emergency procedures, and best practices.

Through direct observation, supervisors can assess the effectiveness of the training as personnel apply their learning in real-time situations. By ensuring that safety measures are not only understood but also reinforced through practical application, the risk of accidents or injuries on-site is significantly reduced. Thus, this choice stands out as essential for maintaining a safe working environment during drilling operations.
