Which location should you avoid placing ladders near?

When considering the placement of ladders, it is crucial to avoid locations that could pose hazards to safety. Exhaust pipes should be avoided because they can become extremely hot during operation, which creates a risk of burns or fires if a ladder touches or is too close to them.

Electrical lines represent a significant danger as well. If a ladder comes into contact with electrical lines, it can cause serious electrical shock or electrocution. This risk is particularly heightened when ladders are metal, which conducts electricity.

When fire is showing, such as in the case of a fire emergency, placing a ladder too close can put individuals in danger of flames and smoke inhalation. It is critical for safety personnel to maintain a safe distance from active fire scenarios to protect their lives and ensure they can operate effectively.

Given these serious safety concerns associated with each of these hazards, the best practice is to avoid placing ladders near exhaust pipes, electrical lines, and fire while operating or working in environments where these conditions are present. Therefore, choosing the option that encompasses all these dangerous locations is the most prudent and safety-conscious decision.
