Never work below a bulldozer because of:

Working below a bulldozer poses significant risks primarily due to the danger of falling and rolling materials. Bulldozers are powerful machines used to clear vegetation and create fire lines, and as they operate, they can disturb the ground and cause debris or loose materials to fall. These materials can include rocks, branches, or even parts of the soil that have been disturbed, which can roll downhill or fall from the machine itself.

The nature of the terrain can complicate this further, as the slope may contribute to the likelihood of materials moving unexpectedly. Being under a bulldozer during its operation means that you are directly exposed to any falling or rolling hazards, thereby increasing the risk of injury or fatality.

The other considerations, such as visibility issues due to dust, potential distractions from noisy machinery, or the need to keep an eye on spotting fires, while they are important safety factors, do not directly relate to the inherent dangers of working in the position below the machine. The primary focus on the risk of falling and rolling materials highlights the critical safety protocol that dictates keeping a safe distance from heavy equipment during operations.
