OSHA 30 Hour Construction Program Practice Test

In what way should flexible cords not be used?

1. Run through walls, hidden in ceilings, or installed in conduits

2. Laid flat on the ground, attached to metal surfaces, or exposed to water

3. Coiled up while in use, placed in accommodating locations, or used with adaptors

4. Connected to high-power devices, wrapped around poles, or used with other cords

The correct answer is: Run through walls, hidden in ceilings, or installed in conduits

The correct answer highlights that flexible cords should not be run through walls, hidden in ceilings, or installed in conduits due to safety regulations and potential hazards. Flexible cords are designed to be used as temporary wiring for portable devices and should not be utilized in permanent electrical installations. When cords are run through walls or other structures, it can create risks such as overheating, as they may not dissipate heat effectively. Additionally, these practices can lead to damage of the cords which might not be easily detectable, increasing the likelihood of electrical failures or fire hazards. This understanding underscores the importance of adhering to electrical codes that dictate how electrical wiring should be installed and maintained. Maintaining the integrity of flexible cords and ensuring they are used in their intended manner is essential for minimizing risk in construction and workplace environments.
