To limit fatigue and injury, you should work within the capabilities of the _____ and use the tool properly.

• A. Equipment
• B. Operator
• C. Environment
• D. Personnel

Answer: (A)

Work within the capabilities of the equipment because tools have limits that, if exceeded, directly drive fatigue and the risk of injury. Each tool is designed for a specific range of tasks, with factors like weight, power, leverage, duty cycle, and cutting or prying capacity. When you choose the right tool for the job, inspect and maintain it, and use proper technique, you keep the workload within what the tool can safely handle. Pushing a tool beyond its rating or using it incorrectly forces you to compensate with body effort, increases strain, and can lead to tool failure or loss of control. While the operator, environment, and personnel matter, the guidance here emphasizes respecting the tool’s limits as the primary way to prevent fatigue and injury.
