DID YOU KNOW?
2022 was one of the deadliest years for trench accidents in recent history, with trench-related fatalities nearly doubling. [2]
KNOW THE RISK
- Trenches and excavations pose a number of serious hazards to workers, especially when proper safety procedures are not followed.
- Trench collapses and cave-ins are the leading causes of death on excavation sites, often occurring with little or no warning. [1]
- Other potential hazards include falls, falling equipment, hazardous atmospheres, water accumulation, and contact with underground utilities. [1]
MITIGATE THE RISK
1. Use Protective Systems in Trenches Over 5 Feet Deep
- OSHA requires that trenches deeper than 5 feet have a protective system such as sloping, shoring, or shielding to prevent collapse. [1]
2. Involve a Professional Engineer for Trenches Over 20 Feet
- Protective systems for trenches deeper than 20 feet must be designed by a registered professional engineer or be based on tabulated data prepared by one. [1]
3. Test for Hazardous Atmospheres
- Excavations may have low oxygen or contain toxic gases. Always test before entry and ensure proper ventilation if needed.
4. Keep Heavy Equipment and Materials Away From the Edge
- Machinery, spoil piles, and tools should be kept at least 2 feet from trench edges to prevent collapse and falling objects. [1]
CONSTRUCTION SAFETY REMINDER
Every trench has the potential to turn deadly. Protective systems, atmospheric monitoring, and site control aren’t optional — they’re life-saving necessities. Never enter an unprotected trench. One misstep could be your last.
