Blackline Safety says that its G7c gas detection instrument has achieved a mandated certification for construction, performance, and test. The product is equipped with a combustible gas sensor and is certified for sale in all major markets.

Combustible gas sensors measure the lower explosive limit (LEL) of flammable gases, expressed as a percentage of the lowest gas concentration that could result in an explosion if ignited.

G7c from BlacklineEmployees in many industries face the hazard of working in environments with the potential for exposure to combustible or flammable gases such as natural gas, hydrogen, and acetylene.

The company says that its G7c features internal 3G wireless communication, location technology, and automatic incident detection capabilities. The device alerts live monitoring personnel when an employee requires help.

A built-in industrial-grade speakerphone allows monitoring personnel to speak directly with the employee to assess the situation and customize the response.

Single-gas and quad-gas cartridges support an LEL sensor to detect combustible gases. The company says that industries where personnel enter confined spaces often use a quad-gas instrument with combustible gas, hydrogen sulfide (H₂S), carbon monoxide (CO) and oxygen (O₂) sensors.

Blackline says its G7c product achieved certification for its LEL sensor construction, performance, and test according to CSA C22.2 NO. 152-M1984 (R2016) Combustible Gas Detection Instruments and ANSI/ISA-S12.13: 2000 Performance Requirements for Combustible Gas Detectors.
