What should an operator do if they notice a strong smell of gas when using a power tool?

When an operator notices a strong smell of gas while using a power tool, the most appropriate action to take is to immediately stop using the tool and check for leaks. This response is crucial for safety reasons; a strong gas odor indicates that there may be a leak in the fuel system, which could lead to serious hazards such as fire or explosion.

Turning off the tool prevents any potential ignition sources from activating while the operator addresses the issue. Checking for leaks allows the operator to identify the origin of the odor, whether it is from a fuel line, a connection, or another component of the tool. Taking this precaution not only helps ensure personal safety but also protects others in the vicinity and helps maintain the integrity of the tool itself.

In contrast to this correct response, other options present less safe practices. For example, changing the fuel type does not address the immediate concern of a possible gas leak, and continuing to use the tool could drastically increase the risk of an accident. Additionally, opening the tool's casing for inspection can be unnecessary and potentially dangerous without first ensuring that the tool is turned off and that safe handling protocols are followed.
