Cylinders in storage outside of buildings awaiting use, resale, or part of a cylinder exchange point must be located a minimum distance of ___________ feet from any doorway or opening in a building where occupants have at least ___________ means of egress.

The requirement that cylinders in storage outside buildings must be located a minimum of 5 feet from any doorway or opening in a building applies to ensure safety by preventing potential hazards associated with liquefied petroleum gas. This distance is crucial because it helps mitigate the risks of gas accumulation near building openings, where people may enter or exit. Moreover, when occupants have at least two means of egress, this further emphasizes the importance of having a safe distance to reduce the risk of fire or explosion, especially in emergency situations where quick exits are necessary.

The requirement for two means of egress highlights the importance of ensuring that there are alternative routes for occupants to leave the building safely in the event of an emergency. This consideration in the placement of gas cylinders is part of establishing safe practices for handling flammable gases and promoting overall building safety, thereby aligning with the principles outlined in NFPA 58.

This strategic placement and regard for egress routes work together to create a safer environment for both occupants and emergency responders.
