Key Questions

The following key questions are answered in this module:

What is the 'line of authority'?
The line of authority at your mine is the formal chain of command supported by job roles, shift responsibilities, and communication protocols as established by the mine operator.

How and when should you learn about your mine's line of authority?
During training and orientation, your supervisor or the mine operator should provide you with information on the mine's organizational structure, policies, and procedures as they pertain to your specific role.

Where does the line of authority begin?
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 jobsite.

Why is it important to understand a mine's line of authority?
In addition to MSHA's requirement that miners receive training on the line of authority at their mine, it's important to know who to contact and individual responsibilities regarding safety concerns and emergencies.

What is unique about the responsibilities of a miners' representative?
A miners' representative helps facilitate independent communication between federal authorities and individual miners.

What limits do mine operators have with regard to granting access to their mine sites?
Mine operators have the authority to limit access to their site, with the exception of inspection and other authorized personnel.
