Topic 1: Halon Systems Part 1
A company within your jurisdiction has installed, and still maintains, an outdated Halon system protecting their critical computer servers. The company is looking to upgrading and changing out some servers in that room and also some minor room modifications. First, is it permissible to keep the current Halon system in the room? If they do have to change out the Halon system what type of system would be appropriate and why? Note: Halon is still in use today. It is often re sold by the owner as part of a system upgrade.
Topic 2: Halon System Part 2
What are the possible health effects from being exposed to a Halon total flooding system? What precautions are taken to limit occupant exposure? Note: Think about what reduces the chances of exposure? Pre- warning alarms? How does this help protect lives?
Chapter 9: â€œWet and Dry Chemical Extinguishing Systemsâ€
Wet and dry chemical extinguishing systems provide an alternative to water where the use of water could have little effect, no effect, or make the situation worse. The most common use for wet chemical extinguishing systems is to extinguish fires in commercial kitchen cooking equipment. The most common use for dry chemical extinguishing systems is to extinguish flammable and combustible liquid fires. Both systems use similar types of components, share design and operational characteristics, and in many instances are pre- engineered. In addition, these systems use a gas to expel the agent, operate by manual and automatic means, and have a finite amount of extinguishing agent available to extinguish a fire. In this chapter, the discussion covers the applicable design standards, components, agents, types of systems, applications, and inspection, testing, and maintenance associated with fixed wet and dry chemical systems.
Chapter 10: â€œGaseous Agent Extinguishing Systemsâ€
Water has been and continues to be the most important and abundant suppression agent to combat most types of fires. However, the innovation and development of new materials, machines, processes, and technologies throughout the past 100 years set in motion the need to create alternative extinguishing agents that could deal with fuels in situations where the use of water as the suppression agent could make the situation worse. In some cases, the environment, logistics, and technological application made it impractical to use and store the large quantities of water necessary to control and extinguish a fire. Another consideration leading to the creation of alternative agents was the need to prevent water damage to extremely valuable or irreplaceable property and equipment.
