Which hazard is associated with high-voltage electrical systems?

• A. Exposure to low voltage
• B. Electrical shock
• C. Structural failure
• D. Inadequate signage

Answer: (B)

The association of high-voltage electrical systems with electrical shock is significant due to the nature of high voltage itself. High-voltage systems carry electrical energy at levels that can easily overcome the resistance of the human body, leading to severe electrical shock, injury, or even death.

When working with or around high-voltage systems, technicians must be acutely aware of the risks involved. Electrical shock can occur if a person comes into contact with live electrical components, creating a circuit that can lead to current flowing through the body. This underscores the need for proper safety measures, including the use of personal protective equipment (PPE), adherence to safety protocols, and the implementation of lockout/tagout procedures to minimize the risk of accidental contact.

Understanding electrical shock as a primary hazard emphasizes the importance of safety training and awareness for anyone working in telecommunications environments where high-voltage equipment is present.
