What is the required distance for a tank between 501-2,000 WC from a building?

The required distance for a tank with a capacity of 501-2,000 gallons from a building is 25 feet. This regulation is in place to ensure safety by minimizing the risk of a fire hazard and allowing for adequate space for any potential leaks to be managed without impacting structures nearby. The distance serves to protect both the tank and the building from potential damage or hazards associated with flammable materials.

The choice of 25 feet particularly aligns with safety standards set forth by various regulatory bodies, reflecting considerations around ventilation, accessibility for emergency response, and mitigation of environmental impacts should an incident occur. Distances shorter than this may not offer enough protection or allow for safe operations surrounding the tank, while greater distances may be unnecessarily conservative in most typical installations.
