What tool might be most effective for breaching walls during a rescue?

The most effective tool for breaching walls during a rescue is the rotary saw or forcible entry tools. Rotary saws are specifically designed to cut through various building materials quickly and efficiently, allowing rescuers to create openings in walls to reach trapped individuals. These tools are equipped with high-speed blades capable of slicing through wood, metal, and masonry, making them versatile for different situations encountered during rescues.

Forcible entry tools, such as axes, sledgehammers, or Halligan bars, can also play a crucial role in breaching walls when traditional cutting methods are impractical. They allow firefighters to exert significant force to break down barriers or create openings without the need for complicated setups or prolonged operations.

In contrast, the other options, while useful for certain tasks, are not as effective for wall breaching during rescue scenarios. Chainsaws, although powerful, may be less practical in tight spaces and can take longer to set up for breaching walls. Hand saws and leverage bars lack the efficacy required for rapid breaches, while jackhammers are typically too heavy and cumbersome for use in structural rescues, focusing more on the demolition of pavements or concrete rather than accessing confined spaces.
