Corrosion exists in almost every fire sprinkler system installed. Some systems are always filled with water – wet pipe systems. Some systems have air in the pipes until the system is called to fill with water – dry pipe and pre-action systems. Both wet and dry systems have corrosion issues, but they are dramatically worse in dry systems.
The ability for the gaseous agent to be retained in the protected room for an extended period of time is critical to the performance of any total flooding clean agent fire extinguishing system. NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems, requires that a minimum concentration of 85% of the adjusted minimum design concentration be held at the highest level of combustibles for a minimum period of 10 minutes. Those installing these systems are required to perform a Room Integrity Fan Test to assure the protected room will hold the agent for the required period of time.
This week I joined industry leaders and experts in Las Vegas for the NFPA Conference and Exposition. The mission of the National Fire Protection Association is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating consensus codes and standards, research, training and education. Each year I find this conference to be a tremendous opportunity to connect with so many of my peers and to learn about the new trends in Fire Protection. I’d like to share just a few of my observations from the three days I spent at the conference.
We frequently are asked to respond to questions about fire protection of mission critical facilities. From time-to-time we get a really great question and share our answer on this blog to benefit anyone else who may have a similar question.
“I am continuously looking for ways to reduce the cost of maintaining the systems in our buildings. What is one significant way I can lower the cost of the periodic Inspection, Testing and Maintenance program for my fire protection systems?”
