When monitoring confined spaces for safety, what is a primary concern?

Ensuring proper air quality is a primary concern when monitoring confined spaces for safety because these environments can present significant health risks due to the potential accumulation of hazardous gases, lack of oxygen, or other air quality issues. Confined spaces often have limited ventilation, which can lead to dangerous situations where air contaminants may not disperse effectively. Regular monitoring helps to identify any harmful changes in air quality, ensuring that workers can operate safely without exposure to toxic substances or oxygen deficiency. This focus on air quality is essential for preventing accidents and safeguarding the health of personnel working in such environments.
