Is it true that air monitoring must be continuous during entry into a confined space?

Air monitoring must be continuous during entry into a confined space because maintaining a safe atmosphere is critical to the health and safety of workers. Confined spaces can have varying conditions due to a number of factors, such as the presence of hazardous gases or a lack of oxygen. Continuous monitoring ensures that any sudden changes in the air quality can be detected immediately, allowing for a timely response to protect individuals working in those environments.

Continuous monitoring helps to ensure that the atmosphere remains safe throughout the duration of the work being conducted. This practice is vital as it addresses the risks of gas accumulation or depletion of oxygen, which can be life-threatening. By continuously monitoring, safety teams can intervene quickly if hazardous conditions arise, ultimately preventing accidents and ensuring worker safety in potentially dangerous situations.
