What is a confined space?

A confined space is characterized by having limited means of entry or exit, which makes it distinct from other types of spaces. The constraints typically found in a confined space can lead to safety hazards, such as difficulty in evacuation during emergencies, restricted airflow, and the potential accumulation of harmful substances. This definition is critical for ensuring safety protocols are followed, especially in environments where pipefitters or other workers might be required to perform tasks.

In practice, such spaces are often enclosed or partially enclosed and can include tanks, vaults, or pipelines, which pose risks due to their design. Recognizing the defining features of a confined space is essential for implementing proper safety measures, including atmospheric testing, ventilation, and rescue plans, to protect workers from potential hazards associated with these environments. This understanding reinforces the need for specialized training and equipment when working in these areas.
