biennially and internally quadrennially.
2. Power boilers and high-pressure, high-temperature water boilers shall receive an internal inspection annually where
construction permits and an external inspection while in operation, if possible; otherwise it shall be as complete an
inspection as possible.
3. Under certain conditions — with the chief boiler inspector’s approval — power boilers, waste-heat boilers, and highpressure,
high-temperature water boilers having internal continuous water treatment may be subject to an annual
external inspection while in operation and an internal inspection biennially.
