Which feature is NOT a characteristic of a confined space requiring a permit?

A confined space is defined by specific characteristics that determine whether entry requires a permit. One of the primary requirements for a space to be classified as a confined space is the potential hazards associated with the environment.

Good ventilation is not a characteristic that typically defines a confined space requiring a permit. In fact, one of the main concerns in confined spaces is the potential for inadequate ventilation, which can lead to the accumulation of harmful gases or insufficient oxygen levels. Spaces that are well-ventilated tend to mitigate the risks associated with harmful contaminants and oxygen deficiency.

In contrast, limited openings for entry or exit, potential for dangerous air contaminants, and an atmosphere of oxygen deprivation are all traits that elevate the risk and necessitate a permit for entry. These factors indicate that the space could pose significant health and safety risks to workers, requiring careful protocols to ensure safety before allowing entry.
