What does CGI stand for in gas safety inspections?

In the context of gas safety inspections, CGI stands for Combustible Gas Indicator. This instrument is essential for detecting the presence of combustible gases in an environment, which is critical for ensuring safety during gas inspections. A combustible gas indicator is designed to measure the concentration of flammable gases in the atmosphere and alert inspectors to potentially dangerous levels. This enhances safety by preventing leaks and the risk of explosions or fires associated with high concentrations of flammable gases.

Understanding the role of a combustible gas indicator helps inspectors identify hazardous situations before they escalate, making it a vital tool in maintaining safety standards. It is particularly important in confined spaces or during maintenance activities near gas lines where gas leaks can often go unnoticed. In contrast, the other choices represent terms that are either irrelevant to gas safety inspections or do not have a specific role in monitoring combustible gas presence. The use of a combustible gas indicator is an industry standard practice to ensure the safety and integrity of gas systems.
