Confined Space Basics

OSHA's Confined Space Standard

OSHA's standard for confined spaces (29 CFR 1910.146) contains the requirements for practices and procedures to protect employees in the general industry from the hazards of entering permit spaces.

Employees must follow OSHA rules when entering confined spaces.

General industry employers must evaluate their workplaces to determine if spaces are permit spaces. If a workplace contains permit spaces, the employer must inform exposed employees of their existence, location and the hazards they pose. This can be done by posting danger signs such as "DANGER-PERMIT-REQUIRED CONFINED SPACE-AUTHORIZED ENTRANTS ONLY" or using an equally effective means.

If employees don't need to enter and work in permit spaces, employers must take adequate measures to prevent them from entering these spaces. An employer is required to block or securely seal off the confined space so employees cannot enter the area. If employees are expected to enter permit spaces, the employer must develop a written permit space program and make it available to employees or their representatives.
