G7 wearables and G7 EXO area monitors constantly detect both VOC ambient gas levels and the employee's location, reporting this data back to the cloud wirelessly via cellular or satellite connectivity. These devices utilize advanced sensors for VOC detection, capable of measuring very low concentrations of organic chemicals and other air pollutants that can affect indoor air quality.
Every reading streamed to the cloud ensures that all data is immediately available for visualization of PID readings on a map overlay, giving Industrial Hygienists and HSE Managers the ability to identify hotspots and problem areas and take proactive action to address an issue before it becomes an incident. This real-time monitoring is crucial for detecting VOC emissions from various sources such as building materials, office equipment, cleaning supplies, and industrial emissions.
PID VOC
The devices employ photoionization detection (PID) technology, which uses UV light to ionize VOCs with ionization thresholds below the photon energies emitted by the lamp. This method allows for the detection of a broad spectrum of organic solvents and other gases, even at very low concentrations that may not be visible to the naked eye. VOCs, which often have a high vapor pressure at room temperature, can originate from numerous sources including paint strippers, permanent markers, photographic solutions, and craft materials. Many VOCs are known to have adverse health effects, potentially impacting the central nervous system and causing throat irritation among other symptoms.
While many VOCs are invisible to the naked eye, their emissions contribute significantly to indoor and outdoor air pollution. These compounds, characterized by their high vapor pressure, readily evaporate into the air, joining other air pollutants to create complex mixtures. Unlike visible light, which we can easily perceive, VOC emissions often go unnoticed until they reach concerning levels. Many VOCs, along with other air pollutants, can have serious health implications, making their detection and management crucial for maintaining air quality. From industrial processes to everyday household products, the sources of these volatile organic compounds are diverse, underscoring the importance of comprehensive air quality monitoring and control measures.
The G7 ecosystem's ability to detect and monitor VOCs is particularly valuable in preventing and responding to chemical spills, as well as maintaining overall air quality in various environments. By providing real-time data on VOC levels, these devices enable proactive measures to protect human health and ensure a safer working environment.
