Excavation is often one of the first steps in construction no matter what you’re building. From digging out a basement, trenching for sewage and utility lines to preparing the foundation, they all involve excavation. Since we’re an expert in this subject with decades of experience and solid safety record, we have some trenching and excavation safety tips for you.
Potential Excavation Safety Hazards
Soil looks heavier than it seems, a cubic yard of dirt weighs about the same as a car. If unstable soil isn’t supported, it could collapse and injure people both under and above the surface. If heavy equipment or removed soil is stored too close to the excavation, it could fall into the hole or put too much pressure on trench walls. Workers and machines could also come in contact with utility lines such as gas, power and water; and workers could also be exposed to hazardous atmosphere such as vapour or dust. Above the surface, there may be overhead power lines or structures nearby which heavy machinery could accidentally hit. Of course, workers could also be struck by moving machinery an flying debris. The list goes on…
Excavation Safety Tips
- Identify the soil types in order to prevent associated risks. Soil properties may vary within a single trench.
- Locate and de-energize buried as well overhead services, such as gas and power lines.
- Obtain required permits.
- Check areas near the work site for equipment, objects, buildings or structures that may affect the stability of the soil or put pressure on the trench walls.
- Provide adequate bracing for trench walls, also known as trench shoring.
- Test for hazardous atmosphere before entering.
- Remove water from excavation.
- Provide means of exit for workers inside.
- Plan for adverse weather and emergencies.
- Follow safety standards and practices.
The list above is by no means comprehensive. It is best to follow your local occupational health and safety regulations related to excavation and trenching. For legislative requirements in Saskatchewan, please visit Saskatchewan Construction Safety Association’s website.
