Washington Pre-instruction Checklist for Low Pressure Steam Boilers is a document that provides guidance to inspectors and facility staff members to ensure that the inspection process for low pressure steam boilers is performed in accordance with applicable codes and regulations. The checklist covers a variety of topics, including safety, installation, maintenance, and operation. It includes a detailed list of inspection items including: • Verifying that the boiler is registered and has a valid Certificate of Operation (COO) • Inspecting safety devices such as safety valves, pressure gauges, and other safety equipment • Inspecting for proper installation and maintenance of the boiler and related equipment • Verifying that the boiler is properly vented and has sufficient water supply • Checking for any visible damage or signs of leakage • Examining the boiler's interior, including tubes and other components • Testing burner and fuel supply systems • Examining the boiler's control systems, such as thermostats and other controls • Testing the boiler's pressure, temperature, and other operating parameters There are two types of Washington Pre-instruction Checklist for Low Pressure Steam Boilers. The first is the Standard Checklist, which is designed for standard boilers, and the second is the Advanced Checklist, which is designed for more complex boilers.
