Who can you consult to determine the voltage of electrical lines?

1. Safety observer

2. Colleague

3. Equipment supplier

4. Site manager

The correct answer is: Safety observer

Consulting a safety observer to determine the voltage of electrical lines is a sound choice because safety observers are typically tasked with ensuring compliance with safety regulations on construction sites and are well-versed in the specific hazards associated with electrical lines. They are trained to identify safety issues and can provide vital information regarding the characteristics and risks of electrical systems. A safety observer usually has the authority and knowledge to assess the work environment, understand the plans in place for electrical systems, and recognize the voltage levels involved. This makes them a reliable source for obtaining information about electrical lines, ensuring workers can proceed safely in their tasks. While a colleague could potentially provide insights if they have relevant experience or knowledge, they may not have the formal training or credentials to ensure the accuracy and safety of the information. Equipment suppliers often provide data on their specific products and their capabilities, but may not have the comprehensive knowledge about all external electrical lines on-site. The site manager, while responsible for overall site safety and operations, may not always have intimate details about the electrical systems unless specifically briefed on their condition and specifications. In this context, the safety observer emerges as the most appropriate person to consult regarding electrical line voltages, mainly due to their focused role in maintaining safety standards and awareness on the
