When checking the roof, in what direction should your thumb be pointed?

When checking the roof in a mining context, having your thumb pointed outby is the correct practice. The term "outby" refers to the direction of the mine entrance, which is the area where miners typically enter from and exit to the surface. Pointing your thumb in this direction while assessing the roof indicates that you are oriented toward a safe exit and keeping awareness of the mine layout and airflow.

This practice also reinforces the importance of being mindful of your surroundings, particularly when checking for safety hazards or signs of instability in the mine roof. It helps ensure that you are always aware of your escape route and can react appropriately in case of unforeseen circumstances.

In contrast, other directions could potentially signify inattention to safety protocols or misalignment with established safety practices in the mine. Proper orientation is crucial for maintaining awareness and minimizing risks while performing inspections or other activities in the mining environment.
