An SCBA is a sophisticated respiratory protection device designed to provide clean, breathable air in environments where the ambient air is unsafe. Unlike masks or air-purifying respirators that rely on filtering contaminants, SCBAs supply air from a high-pressure cylinder, offering complete protection against toxic gases, fumes, smoke, and oxygen deficiency. https://www.leadclub.net/classifieds/business-opportunities_2/publishing/safety-breathing-apparatus-dipti-fire-services_i90177
