Confined Spaces in Construction
Overview
Confined spaces - such as manholes, crawl spaces, and tanks - are not designed for continuous occupancy and are difficult to exit in the event of an emergency. People working in confined spaces face life-threatening hazards including toxic substances, electrocutions, explosions, and asphyxiation.
This webpage contains information on the new regulation, compliance assistance documents, and other resources OSHA has to help employers and workers understand the rule. OSHA will continue to publish new guidance products in the coming months, and will post them here. Please check the website often for updates.
Construction workers often perform tasks in confined spaces - work areas that (1) are large enough for an employee to enter, (2) have limited means of entry or exit, and (3) are not designed for continuous occupancy. These spaces can present physical and atmospheric hazards that can be prevented if addressed prior to entering the space to perform work. This page is a starting point for finding information about these spaces, the hazards they may present, and ways to safely work in them.

Workers' Rights
Workers have the right to:
- Working conditions that do not pose a risk of serious harm.
- Receive information and training (in a language and vocabulary the worker understands) about workplace hazards, methods to prevent them, and the OSHA standards that apply to their workplace.
- Review records of work-related injuries and illnesses.
- File a complaint asking OSHA to inspect their workplace if they believe there is a serious hazard or that their employer is not following OSHA's rules. OSHA will keep all identities confidential.
- Exercise their rights under the law without retaliation, including reporting an injury or raising health and safety concerns with their employer or OSHA. If a worker has been retaliated against for using their rights, they must file a complaint with OSHA as soon as possible, but no later than 30 days.
