Which unsafe act would likely lead to accidents near machinery?

Placing hands near moving parts is an unsafe act that significantly increases the risk of accidents near machinery. When a worker puts their hands near moving components, they expose themselves to severe injury, such as being caught in gears, belts, or other mechanical parts. This behavior ignores the fundamental safety principle of maintaining a safe distance from dangerous areas of machinery, where contact could lead to crushing or laceration injuries.

In contrast, taking actions like stepping back from running equipment or wearing appropriate safety gear are practices that promote safety rather than contribute to risk. Following all safety protocols also enhances safety by ensuring that workers engage in behavior that minimizes risk. Therefore, it is crucial to always be aware of moving parts and to maintain a safe distance to prevent accidents.
