5 feet

10 feet

The maximum distance from the edge of a motor fuel pump enclosure that a hazardous location extends is specified to be 10 feet. This is crucial for ensuring safety when working around fuel pumps, as hazardous locations are areas where flammable gases or vapors may be present due to the nature of the materials being handled.

The 10-foot distance is determined based on the potential for vapors to escape from the pump area and become ignitable when mixed with air. This guideline helps to establish safety zones around fuel dispensing equipment, which is essential for preventing explosions or fires.

Understanding the extent of hazardous locations around fuel pumps is critical for electricians and other professionals who work in environments where flammable materials are present. It informs not only the placement of electrical equipment but also workers' safety protocols, making it necessary to adhere to these defined limits to protect personnel and property effectively.
