The blank in the sentence "working near power lines, __________ is a serious consideration." is best filled with "electrocution." This is because working near power lines poses a serious risk of electrocution due to the high voltage present.
Explanation:
- Working near power lines can be very dangerous primarily due to the risk of electrocution, which can cause fatal or severe electric shock and burn injuries. Even without direct contact, electricity can arc over a gap if a person or equipment comes too close to a live line. This makes electrocution the key serious consideration when working near power lines.
- Safety procedures emphasize maintaining safe distances based on the voltage of the power lines, using proper protective equipment, and careful planning to avoid electrical hazards.
Therefore, completing the sentence: "working near power lines, electrocution is a serious consideration." is the correct and safety-relevant choice.
