Confined Space Entry
A confined space means a space that:
- Is large enough and so configured that an employee can bodily enter it,
- Has limited or restricted means for entry and exit, and
- Is not designed for continuous employee occupancy.
Employers must establish procedures and methods in accordance with OSHA for safe entry into confined spaces. Sanitary sewer manholes require a written confined space entry permit due to the hazardous characteristics. OSHA requires employers to ensure that their workers know about the existence, location, and dangers posed by permit-required confined spaces.
