Why were trench cutting operations slow?

The reason trench cutting operations were slow is due to the encounter of two levels of roofing boards. This situation adds complexity and difficulty to the cutting process. When firefighters are faced with multiple layers of roofing, it requires additional time and effort to effectively cut through each layer. Each layer may have different materials, thicknesses, and structural support, which can hinder progress and complicate the operation.

In contrast, lacking proper tools would likely lead to a lack of efficiency but would not inherently slow down the process as significantly as dealing with multiple roofing levels. Extreme weather conditions can impact overall operations, but it may not have a direct effect on the trench cutting itself. While inexperience can affect performance, experienced firefighters might still be able to manage the task adequately, though it may take longer than anticipated due to the structural challenges posed by the roofing layers.
