How far can meters be from the source of ignition?

• A. 3 ft
• B. 5 ft
• C. 10 ft
• D. 15 ft

Answer: (B)

Keeping ignition sources at a safe distance from gas meters is about preventing a flash fire if a propane leak occurs. Propane is heavier than air, so leaked gas tends to settle low and move along the ground toward any nearby ignition source. By establishing a buffer, such as a five-foot separation, you reduce the chance that a spark, flame, or hot surface will encounter enough gas to ignite. This distance provides a practical safety margin for maintenance access and reduces the risk of a dangerous ignition. Five feet is the minimum distance used to balance safety with practical placement, making it the best answer. Distances shorter than that increase ignition risk, while greater distances are more conservative than necessary for typical installations.
