Sample Video Transcript
The true line of authority begins with the individual miner. It is your right and responsibility to act on the behalf of your own health and safety, with consideration to everyone else at the job site. Therefore, it is your responsibility to: work safely, following established health and safety standards or decline to work in unsafe conditions as appropriate, maintain a safe working area and recognize and report health and safety concerns or request an inspection of unsafe conditions.
