Hazards from tools can be categorized into danger from the tool's action and danger from ______.

The correct answer focuses on the physical aspects of the tools themselves beyond the actions they perform. Hazards can arise from various power sources that tools rely on to function, such as electricity, batteries, or pneumatic pressure. Understanding the dangers associated with these power sources is crucial for ensuring safe operation, as improper handling or failures in these systems can lead to serious accidents or injuries.

While user error, surroundings, and worn materials can certainly contribute to overall risk, the specific categorization in this context emphasizes the inherent hazards posed by the energy that drives the tools and machinery. Identifying and managing these power-related hazards is essential for maintaining a safe working environment.
