Final answer:
The possible electrocution hazard among the provided options is working on equipment across the street from overhead power lines. Electrical safety practices like wearing insulated shoes and working one-handed are essential to prevent electrocution. Devices such as fuses and circuit breakers also contribute to safety by preventing overloading.
Step-by-step explanation:
Possible electrocution hazards are conditions or actions that could lead to someone receiving an electric shock or other injuries from electricity. Option D, working on equipment across the street from overhead power lines, is a possible electrocution hazard because one could accidentally come into contact with live electrical parts or power lines and become a pathway for electrical current to the ground, leading to electrocution.
Electrical safety measures are critical to prevent both thermal hazards and shock hazards. For example, insulated shoes help prevent a pathway for current flow through the feet, and working 'one-handed' reduces the potential for a current path through the heart. Moreover, electrical systems should be designed with devices like fuses and circuit breakers to prevent overloading, which reduces the risk of fires and electric shocks.
