What is a common hazard associated with man hole covers?

Slipping is a common hazard associated with manhole covers due to various factors that can affect traction when crossing over them. Manhole covers can become slick, especially when they are wet or covered with debris, such as leaves, oil, or other contaminants. This lack of traction increases the risk of slips and falls for pedestrians and workers navigating the area. As people walk over or near manhole covers, they may not have adequate grip, leading to accidents, particularly in high-traffic locations or work sites where safety is a crucial consideration.

In contrast, while overheating, falling debris, and corrosion can pose risks in certain contexts, they do not typically relate directly to the immediate hazards posed by manhole covers in urban or outdoor environments. Overheating generally pertains to machinery or electronic equipment rather than manhole covers. Falling debris is more of a concern in construction zones or unstable environments, and corrosion is usually a long-term issue that impacts the integrity of metal covers over time rather than an immediate hazard for pedestrians.
