A confined space (and a permit-required confined space) must have an entry port that is large enough to allow full-body entry. If the entrance is too small for a worker to completely enter, or if the space itself is too small for a worker to completely enter, then OSHA’s standard does not apply.
How do you create a confined space?

What is the difference between a confined space and a permit required confined space?

At what depth do excavations require shoring?
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 the OSHA standard for confined space?
OSHA’s standard for confined spaces (29 CFR 1910.146) contains the requirements for practices and procedures to protect employ-ees in general industry from the hazards of entering permit spaces. Employers in general industry must evaluate their workplaces to determine if spaces are permit spaces.
