restricted space

Access-controlled tight quarters

A restricted space is an area with limited or controlled access, typically requiring authorization to enter.

The term appears in workplace safety contexts for confined areas like tanks, tunnels, or crawl spaces that pose hazards: Workers must complete training before entering any restricted space.

It also applies to secure zones in buildings or facilities where entry is monitored or prohibited.
