The Confined Space Entry Permit is the most essential tool for assuring safety during entry in confined spaces with known hazards or with unknown or potentially hazardous atmospheres. The entry permit process guides the supervisor and workers through a systematic evaluation of the space to be entered.

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.

Rescuer Tragedies. OSHA dictates that the minimum "safe level" of oxygen in a confined space is 19.5%, while the maximum "safe level" of oxygen in a confined space is 23.5%. With low oxygen levels being the biggest cause of death in confined spaces, accurate oxygen level measurements are essential.
