Correct answers: A, C, D
Explanation
When dealing with exposed wires and a burning smell, safety is the top priority. Unplugging the device, cutting power at the circuit breaker if necessary, and avoiding direct contact with hazards are essential steps to prevent electrical shock, fire, or personal injury. Reporting the issue allows trained personnel to address the situation safely.
- A. Correct.
Unplugging the computer from the power source is a critical first step to prevent electrical shock and further damage to the device.
- B. Incorrect.
Using an ESD wrist strap is a safety practice for static discharge, but it is unsafe to continue working when there are exposed wires and a burning smell, as this poses a fire or shock hazard.
- C. Correct.
Turning off the power at the circuit breaker ensures that the electrical hazard is fully neutralized, especially if the burning smell indicates a potential fire risk.
- D. Correct.
Avoiding contact with exposed wires and reporting the issue ensures personal safety and compliance with workplace safety protocols.
- E. Incorrect.
Pouring water on the device is dangerous and can increase the risk of electrical shock or further damage to the equipment.
