Expired Certificate, Overset Relief Valve, and a Hospital Demand
A 60-bed hospital's standby boiler is out for tube replacement, leaving one 350 hp, 150 psig firetube to carry the whole load, including sterilization and domestic hot water. Yesterday's annual inspection found: the boiler's certificate of inspection expired seven months ago; the safety valve is set at 175 psig and weeping; the low-water fuel cutoff has a wire jumper across its switch; the gauge glass has a broken guard and a leaking lower connection; and the last try-lever test was recorded 14 months ago. The inspector tagged the boiler and left a written list. The hospital administrator tells you the boiler 'has to run for 48 hours' because there is no alternate steam source and surgery is scheduled. The maintenance technician says he can turn the relief valve adjusting screw down to 150 psig himself this afternoon.
1. Can the boiler legally and safely be run for 48 hours while these items are corrected? Explain with specific code and jurisdictional reasoning.
Read the worked answer
No, not legally and not safely. Running with an expired certificate violates New Mexico's boiler rules administered by the Construction Industries Division, Boiler Safety Bureau, and it exposes the hospital and the operator to liability if anything happens. The safety valve set at 175 psig on a 150 psig MAWP boiler is a direct code violation: a Section I boiler's safety valve must be set at or below MAWP, and pressure must not rise beyond the allowed accumulation above that. A weeping valve also indicates a damaged seat and it may not relieve at all when needed. The jumpered low-water cutoff leaves the boiler with no automatic protection against a dry fire. The broken gauge-glass guard and leaking lower connection are both a burn hazard and a pressure-boundary concern. A 48-hour run is not a minor exception; it normalizes three separate defeats of safety systems.
2. For each finding, state what is required and who may do the work.

The safety valve must be repaired or replaced and set by a facility holding the VR stamp, set at or below 150 psig, tested, sealed, and documented; plant staff may not turn the adjusting screw. The low-water cutoff jumper must be removed, the float chamber and switch repaired, and the device proven by an evaporation test. The gauge glass, guard, and lower connection must be repaired before firing. The certificate requires reinspection by a commissioned inspector and reissuance by the Bureau. The try-lever test should be performed under pressure and recorded with the valve data. Any pressure-part repair requires NBIC work by an R-stamp holder. The Bureau should be notified of the deficiencies and of the reinstatement date.
3. What do you document and communicate, and what alternatives exist?
Read the worked answer
Document the tag, the inspector's list, and your refusal in writing to the administrator; state the code basis and the specific hazard. Communicate to hospital leadership that the alternative is not 'run it anyway' but a temporary certified steam source, such as a rental boiler with its own inspection and permit, or portable electric steam generators for sterilization, or postponement of nonessential steam loads. Notify the Bureau and ask for priority reinspection. After correction, record the valve setting and seal number, the evaporation test, the gauge-glass repair, and the inspector's approval. Keep boiler logs and training records current. If the administrator insists, escalate to the chief engineer and risk management; an operator's license and public safety are not a 48-hour bargaining chip.
