DOT cylinders must be how far from an opening to a building?

DOT cylinders must be located at least 3 feet from any openings to a building, such as windows and doors. This regulation is in place to enhance safety and minimize the risk of fire or explosion hazards associated with gas cylinders, which contain flammable materials. The distance helps ensure that any potential leak or release of gas does not enter the building and create a dangerous situation for occupants. Adhering to this regulation is crucial for compliance with safety standards and for protecting both people and property.
