What is the primary hazard associated with working in a trench?

Falling loads

Cave-ins

The primary hazard associated with working in a trench is cave-ins. In trench work, the soil surrounding the trench can become unstable, especially if it's not properly shored or if there are changes in moisture or load above. Cave-ins pose a severe risk to workers because they can occur suddenly and without warning, burying individuals under heavy soil, which can lead to fatalities or serious injuries. Proper safety measures, such as using trench boxes or shoring systems, are paramount to mitigate this risk.

While falling loads can be a concern, especially when work is being done above the trench, they do not represent the fundamental danger inherent to the trench itself. Noise exposure and weather-related incidents are also important safety considerations in the construction environment, but they are not specific to the hazards of trench work. Thus, cave-ins remain the most critical concern.
