💡 Key Summary
A confined space is not defined by its structure but by its hazards. Even open areas can be classified as confined spaces if they involve oxygen deficiency, toxic gases, or fire/explosion risks. Over the past decade (2015–2024), 298 workers suffered casualties in confined space accidents, with 126 fatalities — a 42.3% fatality rate. Always measure gas concentrations before entry and follow safe work procedures.
Most people picture a sealed, enclosed room when they hear "confined space." But under Korea's Occupational Safety and Health Standards Rules, a confined space is defined by hazard — not structure. Open areas can qualify if they present risks of oxygen deficiency, toxic gases, or fire and explosion.
Legal Definition of a Confined Space
