Which of the following statements is true regarding confined spaces?

The statement that confined spaces are "large enough to perform work with restricted entry or exit" accurately captures the defining characteristics of confined spaces as outlined by OSHA. A confined space is typically one that has limited means of entry and exit and is not intended for continuous occupancy.

This definition is significant because it establishes a framework for assessing hazards and the necessity for specific safety protocols when working in such environments. The restriction of entry or exit can pose risks, including the potential for hazardous atmospheres or limited visibility, which requires proper safety measures, including sufficient training and the use of personal protective equipment.

The other statements, while they may touch on aspects related to confined spaces, do not accurately depict the complete characteristics that classify a space as "confined." For instance, defining a space as "too small to perform work" does not account for those spaces where work can indeed be performed but where access is limited. Similarly, stating that a confined space is "designed for ongoing occupancy" is incorrect, since these areas are not meant for long-term habitation but for work done intermittently. Lastly, the idea that confined spaces are "only accessible during emergencies" fails to recognize that they are often accessed for planned work activities, requiring proper safety measures rather than solely being
