Critical Trench Box Safety Tips


Digging trenches is an essential element of several constructions. They are utilized to install telephone lines, pipes as well as any other tubular structure that requires installation deep beneath the ground, like oil drilling rigs. Trenching can be a demanding because the soil used in these regions has high levels of moisture which creates difficulties when trying not only to eliminate all debris from objects, but also to keep yourself safe during this procedure as accidentally exposing your the skin could cause severe injuries.

Trench boxes are necessary for all repairs or construction that requires access to the ground. They can be used to prevent collapse depending on the soil and material quality. Trench boxes are constructed of steel and aluminum frames to temporarily hold them in place before excavation begins. The grout is affixed between two layers, should it be necessary, ensuring that there are no cracks when set up at the ground level.

Pre Installation

It is important to identify any risk that might be present prior to excavation. This includes knowledge of the type of equipment needed and how many people need access, as well as contemplating whether there are other ways in which the work could have been done without risking life and the limb (such low-invasive methods). The pre-excavation survey must include the full risk assessment needed to ensure that any potential hazards are easily discovered. This reduces the risk of unexpected complications down the line.

The depth of the trench is a factor to take into account as well. A 5-foot slab of concrete can be used to support your needs. If your trench is deeper than the stated size, then shoring or sloping is required. However, if the trench is 20 feet deep and does not have straight sides, every building above ground needs to consider the greater danger of foundation movement.

The trench must be accessed by a ladder or steps or ramp. There should be an accessible area of 25 feet of workers whenever an emergency occurs. You could be necessary to test for low oxygen levels or toxic gases by using specially designed containers known as “trench boxes.” These articulated devices are straightforward, however they add the risk of stacking them over one another as you do not know how high the pile will be able to penetrate into their vulnerable bottom.

Care The trench should be looked after

1. Make sure to inspect the trench box and support every day for any damage or any movement.

2. Everyone working on site are required to wear their safety gear and be wearing steel-toed boots.

3. It is recommended to keep any heavy equipment or other tools at least three feet away from the trench’s edge.


In the event of a trench, it will be more challenging than removing it, as the ground surrounding it moves. For removal, you can employ chain slings. An overhead crane is another option.

1. Straight Pull Straight Pull: This is the most fundamental of all extraction methods. Simply attach your sling to two points, then pull it away, not fumbling by using too much force or unnecessary movement.

2. Half Pull: A half pull can be used to secure the trench box to one side and lift as much as possible. You can get rid of dirt and other debris from the trench box without causing any harm.

3. Single Pull to relocate the trench box you connect a single piece of chain slings to an extraction or lifting point and then raise each panel each time. Use your pull to remove the trench box.
