More Excavation and Trenching Safety Hazards In Construction Projects

In the recent article, we talked about cave-ins and falls and falling loads as job site hazards in excavating and trenching tasks in construction operations. We continue to talk about other excavation safety hazards.

Hazardous air. In some cases, the trenched areas have depleted oxygen levels. Also, toxic gases and chemicals may affect the atmosphere in trenched areas. This is a safety hazard that must be anticipated on excavation sites. For these reasons, it is required to do atmospheric testing by a qualified professional in excavations more than four feet. If air is contaminated, then workers must wear the proper protective gear or respirator mask suitable for the hazard in the excavated area.

Mobile equipment. Accidents involving mobile earthmoving equipment are a common hazard of trenching sites. Mobile equipment operators might have an

Obstructed view of the mobile equipment operator may lead to a job site accident. For example, an operator may fail to detect an approaching perimeter of the trench due to obstructed view. That’s why it is advised that a spotter or a flagger should guide the mobile equipment operator to prevent the vehicle from falling in the trench. In areas of loading or unloading of materials, workers are required to stand back from the construction vehicle to prevent being hit by flying debris.

Working around mobile equipment has risks and wearing the right protective gear will minimize the hazard. Workers are required to wear reflective vests for visibility purposes and a hard hat to protect the head from construction debris.
