The safe evacuation distance from a propane tank when there is a pronounced noise from the relief valve is best set at 2000 feet. This distance is recommended to ensure the safety of individuals in the vicinity due to the potential for a propane release or explosion.

When a propane tank's relief valve is making a pronounced noise, it indicates that the pressure inside the tank is too high, which could lead to a release of propane gas. Propane is highly flammable and can produce an explosive atmosphere, especially if it ignites. Evacuating to a distance of 2000 feet minimizes the risk of exposure to potential harm such as blast radius from an explosion or exposure to toxic fumes released during combustion.

This distance is a standard precautionary measure utilized by emergency responders and is based on the characteristics of propane as well as guidelines for safe distances from hazardous materials. It prioritizes the safety of individuals and allows adequate time and space for emergency services to address the situation effectively.
