Wireless gas sensing brings a new level of worker safety
Gas sensing has always played an important role in worker safety, but the power and accuracy of new wireless-based solutions is bringing a new level of protection. Sean Ottewell reports.
Die Gasmessung war schon immer wichtig für die Arbeitssicherheit. Durch die Leistungsfähigkeit und Genauigkeit der neuen drahtlosen Lösungen erreicht diese nun ein neues Niveau. Sean Ottewell berichtet.
La détection de gaz a toujours joué un rôle important dans la sécurité des travailleurs, mais la puissance et la précision des nouvelles solutions sans fil offre désormais un niveau de sécurité supérieur. Selon Sean Ottewell.

ireless gas sensing has been available for many years, but as with other wireless solutions it faced concerns about safety
and accuracy and the ability to operate in difficult industrial environments. Today those concerns are history and wireless solutions offer unprecedented levels of monitoring speed and accuracy. For example, RAE Systems has introduced
what it describes as the first wireless, four-gas pumped and diffusion monitor for real-time industrial, oil and gas and emergency response gas detection. Known as QRAE 3, it is designed to significantly enhance worker safety in industrial environments and better protect first responders. The versatile and rugged, one- to four-
sensor gas monitor provides continuous exposure monitoring of oxygen and
combustibles, together with toxic gases including hydrogen sulphide, carbon monoxide, sulphur dioxide and hydrogen cyanide. QRAE 3 is certified for use in hazardous
environments, and is designed for use across a broad array of industries where exposure to toxic gas is a constant safety threat. When a situation arises, safety officers must
make critical, split-second decisions about how and where to deploy resources. They need access to real-time threat data, which QRAE 3 can provide, to help make faster, more informed decisions to protect lives and property, says RAE. QRAE 3’s wireless communication
capability enables access to real-time, remote instrument readings and alarm status – including an innovative ‘man-down’ alarm – from any location, for better visibility and faster response. Real-time hazard readings
