Fire Fighting Pumping Systems At Industrial Facilities

By

  • Dennis P. Nolan, Loss Prevention Manager and Chief Fire Prevention Engineer, Saudi Aramco

Written from the perspective of industrial users, this is the only book that describes how to install an effective firewater pumping system in a pragmatic and budget-conscious way rather than with purely the regulatory framework in mind. Based on the wide-ranging industrial experience of the author, this book is also the only one that deals with the particular risks and requirements of off-shore facilities. This book takes the reader beyond the prescriptive requirements of the fire code (NFPA, UL) and considers how to make the best choice of design for the budget available as well as how to ensure the other components of the pumping system and supporting services are optimized.

Audience

Fire protection engineers, health, safety and environment professionals, safety or loss prevention engineers, and risk consultants. The major industrial market is the Oil and Gas sector, including exploration, production, refining, distribution, chemical processing & storage, engineering and consulting, project engineering, safety experts, and fire & safety regulatory bodies.
