The City of Seattle's Boiler and Pressure Vessel Inspection Program dates back to at least 1906 (the oldest law found to date). Currently, our staff consists of four boiler/pressure systems inspectors commissioned by the National Board, one Licensing Inspector and one accounting technician. Their duties include:
- Inspecting boilers annually and pressure vessels biennially
- Conducting one-time inspections of residential boiler and pressure vessel installations. Note: For this purpose, residential means anything from a single family dwelling up to and including a five-unit, multi-family dwelling (apartments, condos, etc.)
- Conducting specialized inspections for automatic and monitored boiler certification inspections which affect the attendance requirements for particular boilers
- Conducting licensing inspections
- Responding to complaints and conducting accident investigations
