What Are the Dangers of Open Trenches?

• Open trenches pose a number of threats. construction vehicles on the site digging a trench image by Elnur from Fotolia.com

  Open trenches are simply large ditches or grooves cut into the ground. They are especially common during war or military exercises but are also seen in every day places. Open trenches can be found in abundance around construction sites and are often used as fire breaks in rural areas. They can become a major hazard if they are left open and unmarked.

Falling

• Open trenches that are left abandoned, partially covered or unmarked with appropriate construction signs pose a threat to both pedestrians and vehicles. It is not uncommon to hear reports of individuals badly injured after a fall into an open trench. Vehicles are also prone to driving into an open trench, severely injuring drivers and passengers.

Collapse

• Another inherent danger with open trenches is collapse. This especially affects construction workers who use open trenching methods. A trench may become unstable and collapse, burying the worker alive under tons of dirt and debris.

Drowning

• During heavy rainfall, an open trench can quickly fill with water. Construction workers using a flooded trench are in danger of drowning in the rapid rise of water. Additionally, pedestrians and children can fall into a water-filled trench and drown.

Toxic Fumes

• Another very real threat is the exposure to toxic fumes. Construction workers often become incapacitated or suffocate after exposure to fumes in the enclosed space of a trench. The circular shape inhibits the escape of fumes and can overwhelm workers.
