A device used within the building industry creates a pressure differential to contain airborne contaminants within a designated area. This equipment continuously measures and displays the pressure difference, typically in Pascals (Pa) or inches of water gauge (in. w.g.), between the controlled space and its surroundings. For example, during asbestos abatement or mold remediation, this mechanism prevents the spread of hazardous particles beyond the work zone.
The deployment of this technology offers several advantages. It safeguards worker health by minimizing exposure to harmful substances and protects the general public from potential environmental hazards. Regulatory compliance, often mandated by governmental agencies, is also facilitated. Historically, less sophisticated methods were employed, frequently relying on visual indicators or rudimentary pressure gauges, which lacked the precision and continuous monitoring capabilities of contemporary systems. This has led to improved safety records in high-risk environments.
