Protect workers; Prevent trench hazards


Workers in trenching and excavation jobs need to remain cautious and alert.

According to fatality statistics from the Occupational Safety and Health Administration, trenching-related fatalities more than doubled between 2012 and 2016. In the first five months of 2017, there were 15 deaths and 19 injuries related to excavation and trenching operations.


In light of these startling statistics, here are some basic tips that can protect construction workers who perform excavation and trenching activities:

  • Before entering a trench, the “competent person” – as defined by OSHA regulations – at the jobsite must inspect the trench and the protection system to ensure that the trench is safe to enter.
  • Establish protective measures such as benching, shoring, sloping and shielding for all trenches between 5 feet and 20 feet deep. Trenches 20 feet and deeper require a registered professional engineer to design these systems.
  • Any trench or excavation 4 feet or deeper must have a means of exit. Ladders or ramps must be located no more than 25 feet from any employee while he or she is in the excavation.
  • Assure that no one is working beneath the path of a load that is being lifted by crane, forklift or excavation equipment.
