What is the minimum distance required from sources of ignition during purging?

The minimum distance required from sources of ignition during purging is 10 feet. This regulation is critical for ensuring safety during the purging process, which involves removing air and potential flammable gases from lines or equipment to prevent dangerous situations that could lead to fires or explosions. Maintaining a distance of 10 feet from sources of ignition minimizes the risk of a spark igniting any residual gas that may be present. Safety protocols are designed to protect workers and facilities from the hazards associated with flammable materials, and this specific distance is a standard practice in the industry to effectively reduce potential risks. Recognizing the importance of this safety measure is essential for anyone working with LP gas systems.
