OSHA 30 Hour Construction Program Practice Test

Which of the following is a precaution related to electric cords for power tools?

1. Carry equipment by the cord

2. Use cords to hoist tools

3. Keep cords around heat, oil, and sharp edges

4. Yank the cord to unplug it

The correct answer is: Keep cords around heat, oil, and sharp edges

Keeping cords away from heat, oil, and sharp edges is essential for maintaining the safety and functionality of power tools. Exposure to heat can cause the insulation of the cords to degrade, leading to electrical shorts or fires. Oil can also deteriorate the materials of the cord, making it weaker and prone to damage. Similarly, sharp edges pose a risk of cutting or nicking the cords, which could expose wires and lead to electrical shocks or other hazards. Therefore, this precaution helps ensure the longevity of the equipment as well as the safety of personnel using power tools. In contrast, carrying equipment by the cord puts undue stress on both the cord and the tool, risking damage. Hoisting tools with cords can cause similar damage and creates a significant hazard if the tool were to fall. Yanking the cord to unplug it can lead to fraying or breaking, posing a risk of electrical hazards. Hence, avoiding these unsafe practices is crucial for ensuring workplace safety.
