Expert Insights: Excavation safety pro-tips
Excavation safety has been a regular focus of OSHA in the construction industry. I enjoy the civil phase of construction projects, especially new-build power plants. After the land is cleared of trees and stumps, heavy equipment arrives. The bigger the project, the larger the equipment.
The frightening reality of dirt work is how quickly things can go wrong. I was in a trance watching a large bulldozer push dirt around one day. As it got closer to me, I was amazed by its power. It weighed almost 200,000 pounds, was about 15 feet tall, 12 feet wide, and nearly 30 feet long.
Everything looked normal. Suddenly, I heard a loud popping sound and saw a section of the bulldozer’s track separate; it moved abruptly upwards and fell outward from the body of the bulldozer and toward my direction. It was at least 25 feet of track section. Luckily, I was back far enough out of its line of fire. But that wasn’t always the case; I had been much closer on other days.
There is a lot of guidance available about what to do or not to do. But here’s a bird’s-eye-view of five things I’ve successfully done to keep workers safe that employers should consider doing too:
- Build a plan, communicate the plan, and follow the plan. Workers must have access to the excavation plan and follow it!
- Only a competent, trained person can perform a soil penetration test. I’ve met very few “trained” workers who could perform the penetration test. Many trenches and excavations have collapsed because somebody misclassified the soil type and used improper benching or shoring methods.
- It’s okay if installing a trench box, shoring, or benching takes more time than it takes to do the work. Ensure that proper protections are put in place and are competently installed, inspected, and maintained before workers enter the excavation.
- Identify line-of-fire hazards around equipment and train workers on them. If equipment will be stationary, use a red rope to barricade off the area. Using rope to barricade things can be better than tape in windy conditions and for efficient setup and take-down ease.
- Consider “what if” something went wrong and what workers would do about it. Companies often train workers about what not to do and not what to do in emergencies. Conduct regular mock scenarios and practice rescue responses onsite.
Use the list above, keep it handy during inspections, and create pocket cards for your supervisors. When developing a worksite excavation plan, always follow the safety requirements in OSHA standard 1926.651.
