Can a power tool be used without a guard?

Using a power tool without a guard is not acceptable due to the significant increase in risk of injury it presents. Guards are specifically designed to protect users from accidental contact with moving parts, flying debris, and other hazards that may arise during operation. They help ensure safety by providing a barrier that reduces exposure to these dangers.

Compliance with safety regulations and standards is essential on job sites, and power tools must always be used according to the manufacturer's guidelines, which typically mandate that guards should remain in place while the tool is in operation. Removing or bypassing these safety devices undermines personal safety and the safety of those working in the surrounding area, leading to potential accidents and injuries.

In this context, while there may be various scenarios mentioned in other options that could seem plausible, none justify the lack of a guard. Safety practices emphasize that all tools should always be used with their protective features intact to ensure a safe working environment.
