What is a key characteristic of a Confined Space?

A key characteristic of a confined space is that it may contain a life-threatening atmosphere. Confined spaces are defined by their potential hazards, which can include insufficient oxygen levels, the presence of toxic gases, or flammable vapors. These atmospheric conditions can pose serious risks to individuals who enter the space without proper safety measures or equipment.

In understanding confined spaces, it's crucial to recognize that they often lack adequate ventilation, which can exacerbate these hazardous atmospheric conditions. This emphasis on the potential for life-threatening atmospheres is what fundamentally distinguishes confined spaces from other types of environments, reinforcing the necessity for proper safety protocols and training before entry.
