How does OSHA define "confined space"?

OSHA defines "confined space" primarily as a space that has limited means of entry and exit, which is essential for understanding the hazards associated with such environments. This definition highlights the potential risks involved, as confined spaces can restrict movement and make it difficult to evacuate in the event of an emergency. Such spaces may also contain hazardous atmospheres or conditions that pose additional risks to workers.

By recognizing that a confined space has these limitations, workers and employers can implement the necessary safety measures and procedures, such as monitoring air quality, ensuring proper ventilation, and providing personal protective equipment. This focus on entry and exit access ensures that safety protocols can be put in place to protect employees working within these environments.

The other choices do not accurately reflect the OSHA definition of confined space. For example, a space that is always occupied does not imply any limitations on entry or exit, which is a critical element of a confined space definition. Similarly, a designated storage space may not inherently have limited access, and a space without any restrictions would not qualify as confined at all. Thus, understanding the specific criteria laid out by OSHA helps in recognizing the unique dangers of confined spaces in general industry settings.
