According to PEI RP300, what can a combustible gas indicator be used to detect?

A combustible gas indicator is specifically designed to detect the presence of flammable vapors, such as those found in gasoline and other hydrocarbons. In the context of vapor recovery systems, the indicator helps in identifying vapor leaks, which can pose safety hazards and lead to environmental concerns. By monitoring for these leaks, operators can ensure that the vapor recovery system functions effectively to minimize emissions and prevent the escape of harmful substances.

Using the indicator in this manner aligns with the guidelines of PEI RP300, which emphasizes the importance of monitoring vapor recovery systems to maintain safety and compliance with environmental regulations. This makes the detection of vapor leaks not only a critical safety measure but also an essential part of responsible operation within fuel handling systems.
