Fossil Fuel Power Plant Human-Machine Interface: Alarms

Length: 28 pages
Price: $50.00

This recommended practice is provided for the benefit of design engineers, and ultimately, plant operators. Use of this document will result in a more coherent and useful application of plant alarms for operations personnel. The goal is to reduce alarm descrepancies, clutter, excessive noise levels, and information overload, but it is not intended for post-facturm analysis of events.

The recommended practice will address functional grouping, prioritization, order and consistency, colors, formats and displays, audio tone and pitch, acknowledge, reset, and test functions, as well as nuisance alarms. The primary application for this recommended practice is fossil power plants; however, these guidelines are generic in nature, and suitable for use in other process industries.
