Article 1910.146 specifically addresses confined spaces, which are defined as spaces that are not designed for continuous human occupancy and have restrictions on entry and exit. These spaces can pose significant hazards, such as reduced oxygen levels, toxic atmospheres, or the potential for engulfment. This regulation emphasizes the safety requirements and protocols for entering and working in such environments to prevent accidents and ensure worker safety.

The focus on confined spaces is crucial because these areas often present unique challenges that are not typically present in open work areas, storage facilities, or areas with heavy machinery. Proper training and regulations under Article 1910.146 are essential for mitigating risks associated with these confined spaces, including ventilation needs, atmospheric testing, and emergency procedures, which are not equally relevant in the other space types mentioned.
