Trenching This is probably one of the most dangerous jobs out there for excavation workers. Trenching and excavation work accounts for 112% more fatalities than that of just general construction work.

What is the most frequent cause of excavation fatalities?
In the construction industry, excavation accidents that are most common occur due to “cave ins” and excavation walls collapsing. When the earth’s surface is cut or soil surfaces are depressed by heavy machinery, a cave in or collapse occurs. OSHA reports that excavation accidents usually result in injury and death.
What is the greatest risk of fatality during excavation?
Cave-ins
1. Cave-ins. Cave-ins are, by far, the greatest excavation risk. Also known as trench collapse, 168 workers lost their lives in this type of accident from 2011 to 2018, according to the Bureau of Labor Statistics (BLS).
What is the most common hazard during an excavation?
cave-in
Probably the most common hazard at any work site is the threat of cave-in. A cave-in occurs when walls of an excavation collapse. Cave-ins can be deadly. Wall failures often occur suddenly, with little or no time for the worker to react.
What poses the greatest risk of fatality during excavation activities?
Cave-ins pose the greatest risk and are more likely than some other excavation-related incidents to result in worker fatalities.
What are the top 3 causes of fatalities in construction?
These accidents are known as the “fatal four” of the construction industry: falls, electrocutions, struck by object, and caught between.
What is the number 1 cause of death on a construction site?
Falls
Falls remain the leading cause of work-related deaths in construction, accounting for more than one in three (36.4%) of the total number of fatalities in this industry (401 of the 991 construction fatalities recorded in 2019 were falls to a lower level).
What are the 4 main hazards that can cause a cave-in?
Cave-ins or collapses that can trap or crush workers. Equipment or excavated soil falling on workers (e.g., equipment is operated or soil and debris is stored too close to the excavation). Falling into the trench or excavation. Flooding or water accumulation.
What is the greatest hazard while working in a trench?
Trench collapses, or cave-ins, pose the greatest risk to workers’ lives. To prevent cave-ins: SLOPE or bench trench walls.
What is the main hazards involved in excavation activities?
Summary
- The greatest risk in an excavation is a cave-in.
- Employees can be protected through sloping, shielding, and shoring the excavation.
- A competent person is responsible to inspect the excavation.
- Other excavation hazards include water accumulation, oxygen deficiency, toxic fumes, falls, and mobile equipment.
What is the greatest exposure for death for workers in an excavation or trenching project?
Cave-ins
Cave-ins pose the greatest risk and are much more likely than other excavation-related accidents to result in worker fatalities. Other potential hazards include falls, falling loads, hazardous atmospheres, and incidents involving mobile equipment.
What are some dangers of excavations OSHA?
Trench collapses, or cave-ins, pose the greatest risk to workers’ lives. When done safely, trenching operations can reduce worker exposure to other potential hazards include falls, falling loads, hazardous atmospheres, and incidents involving mobile equipment.
What are the 4 leading causes of death in the construction industry?
The Occupational Safety and Health Administration identifies four leading causes of deaths in construction: falls, struck by an object, electrocutions and caught in or caught between. Falls. These account for 36.5% of construction deaths.
What is the biggest killer in the construction industry?
Asbestos – asbestos is the biggest cause of death amongst construction workers. Understand more about asbestos and how to control the risks from it.
What is the 2nd leading cause of death in construction?
Struck By Objects
The second-most common cause of death in construction is when something strikes a worker, such as a vehicle, machine, or falling object. Many struck-by incidents involve cranes.
What is the largest cause of construction accidents?
The leading cause of these accidents includes falling or flying objects and vehicle accidents. Electrocutions: approximately 8.5% of construction-related fatalities involve electrocutions. Some of the leading causes include contact with power lines, improper use of cords, and no ground-faults.
What is OSHA’s fatal Four?
An astounding 60% of construction worker deaths can be attributed to OSHA’s Fatal Four: falls, electrical, struck-by and caught-in/caught-between hazards (US Dept of Labor, 2017).
How can a person buried only up to their neck suffocate during a cave-in?
Suffocation can occur even if your nose and mouth are not buried. That’s because in a cave-in, heavy soil can put 800 pounds of pressure on your chest and make it impossible to breathe.
What are the two key risks that are associated to trenches?
There are known hazards and risks associated with trench construction and excavation. These include trench collapses, cave-ins and side wall deterioration, of these known risks, trench collapse is the most common.
What is the fatality rate for excavation work?
Research done by OSHA during the course of the revision of the Standard in the 1980’s showed that the fatality rate in excavation work was as much as 112% greater than the rate for construction in general (. 508 per 1000 employees in excavation work as opposed to . 248 per 1000 for construction in general).
Where is the typical point of failure in an excavation?
cave-in
What is the typical point of failure in an excavation? Soil failure is defined as the collapse of part or all of an excavation wall. The most common soil failure is typically described as an unexpected settlement, or cave-in, of an excavation. Soil sliding is the most common factor leading to soil failure.
