How far does the Class I Division 2 hazardous area around a service station dispenser extend outward?

The concept of Class I Division 2 hazardous areas pertains to locations where flammable gases or vapors may be present but are not likely to be in hazardous concentrations under normal operating conditions. The distance that this area extends outward is significant for ensuring safety in environments where fuel dispensers are present.

The correct answer indicates that the Class I Division 2 hazardous area around a service station dispenser extends outward by 20 feet 18 inches. This specific measurement is established based on safety regulations and practices aimed at preventing ignition sources from being too close to areas where flammable gases or vapors could accumulate.

This distance allows for adequate safety buffers, ensuring that any possible leaks from dispensers do not compromise safety by allowing flammable substances to reach a concentration that could lead to ignition. Adhering to these regulations is crucial for maintaining a safe environment for personnel and customers using fuel dispensing systems.

The specifications noted for the extension of the hazardous area are grounded in industry standards and codes aimed at minimizing risks associated with fuel handling and dispensing.
