1) A supervisor at an oil and gas site was not wearing proper PPE during a job and was denied a work permit by an SKM engineer for safety reasons. 2) During the job, the supervisor's goggles prevented an iron splinter from piercing his eye, making him realize the importance of PPE. 3) The near miss experience changed the supervisor's mindset and approach to safety, leading him to emphasize the importance of PPE and safety practices to his workers.
