OSHA 30 Hour Construction Program Practice Test

What can damage electrical cords?

1. Improper use, aging, and abrasion

2. Overheating, too much light exposure, and chemical spills

3. Excessive moisture, high voltage, and environmental factors

4. Infrequent use, temperature changes, and electrical interference

The correct answer is: Improper use, aging, and abrasion

The correct choice highlights important factors that can lead to damage to electrical cords. Improper use, such as pulling or kinking the cord, can create physical stress and lead to internal wire breakage. Aging is another critical factor, as cords can become brittle and lose their protective insulation over time, making them more susceptible to wear and tear. Abrasion occurs when cords rub against rough surfaces or other materials, which can wear down the insulation and expose the wires underneath, posing a safety risk. While the other options mention various conditions that could affect electrical cords, they either do not commonly lead to damage (for example, infrequent use or electrical interference) or present factors that have less direct impact on the integrity of the cord. Therefore, the first choice comprehensively covers the most frequent causes of damage to electrical cords in a construction environment. Awareness of these factors is crucial for maintaining safety and ensuring proper equipment functionality.
