Answers

Workers should not work in an unprotected trench that is 5 feet deep or more. The type of protection installed may be sloping or benching, trench box or shield and steadying.

How deep can trenches be without protection?

Protective systems for trench safety include sloping, shoring, shielding, and benching. They are used when soil conditions and the depth of the trench present a hazard to workers.

Although only required for excavations deeper than five feet, it's a best practice to provide some form of stabilization in all trenches.

Trenches 5 feet (1.5 meters) deep or greater require a protective system unless the excavation is made entirely in stable rock. If less than 5 feet deep, a competent person may determine that a protective system is not required.

What is Shoring?

Shoring is the process of supporting the sides of an excavation to prevent them from collapsing. It is a critical safety measure that must be taken in any trench that is 5 feet deep or more.

The type of shoring that is used will depend on the depth of the trench, the type of soil, and the anticipated load. Shoring must be installed by a qualified professional. It is important to follow the manufacturer's instructions carefully to ensure that the shoring is properly installed and that it will provide adequate protection.

The runner's warm-up can be used in any sport that involves running short distances or long distances. Sports like Track and Field, Cross Country, Soccer, Lacrosse, and Basketball.

The first sport that I thought of was tennis. When I saw the image of the man skipping in the knowledge article, I thought about tennis. I often see players doing stutter steps, which are a lot like skipping. Tennis players also pedal backward, like in the walking backward exercise. I don’t see tennis players walking on their heels, but they do need strong calves, so the walking on heels activity applies as well.
