Trenching and Excavation Stats and Facts

FACTS

  1. Cave-ins: The most prevalent danger, where walls of a trench collapse, burying workers under soil.
  2. Falls: Workers or equipment can fall into unprotected trenches, leading to injuries or fatalities.
  3. Falling Loads: Materials or equipment positioned too close to the edge can fall into the excavation, striking workers below.
  4. Hazardous Atmospheres: Accumulation of toxic gases or lack of oxygen in trenches can lead to asphyxiation or poisoning.
  5. Mobile Equipment: Nearby operating machinery can inadvertently cause soil vibrations, leading to collapses, or can strike workers if not properly managed.
  6. Water Accumulation: Unexpected water ingress can destabilize trench walls and pose drowning risks.
  7. Underground Utilities: Accidental contact with electrical lines, gas pipes, or other utilities can result in explosions, electrocutions, or other serious injuries.
