What precautions should be taken regarding manhole steps?

• A. Never be used as a ladder is always preferred.
• B. Be a minimum of ¼ in. thick to prevent corrosion damage.
• C. Never be trusted and should be inspected before use.
• D. Always be used when entering a manhole to reduce chances of an accident.

Answer: (C)

The appropriate precaution regarding manhole steps is that they should never be trusted and should be inspected before use. This emphasizes the importance of safety and maintenance in wastewater collection systems. Manhole steps may deteriorate over time due to factors such as corrosion, weathering, and other environmental conditions. Therefore, a thorough inspection helps to ensure that they are stable and capable of supporting a worker’s weight. If the steps are found to be damaged or unsafe, alternative methods should be used to access the manhole, as relying on potentially compromised steps can lead to serious injuries or accidents. The choice regarding the thickness of the steps relates to their durability but does not address the immediate concern of safety and inspection prior to use. Similarly, while steps may be used to reduce the chances of accidents, this relies on the assumption that the steps themselves are trustworthy, which is why regular inspections are crucial. The suggestion to never use them as a ladder also does not align with accepted safety practices, as manhole steps are intended to facilitate safe access to underground systems, assuming they are in proper condition.
