(b) The safety factor shall be eight for horizontal-return tubular boilers that have continuous longitudinal lapseams that are more than 12 feet in length. If this type of boiler is removed from its existing setting, it shall not be reinstalled in a manner that allows the boiler to operate at pressures in excess of 15 psig.

(c) The lowest permissible safety factor for new pressure vessels shall be no less than 3.5.

(d) If an existing boiler or pressure vessel is constructed to operate with a higher safety factor than a safety factor required by this regulation, the higher safety factor shall not be lowered for any reason.
