Subject Title
Chemical Extinguishing Systems

Subject Description
This course will address special extinguishing systems and agents. An important course ingredient for the student is to gain an understanding of the relative strengths and weaknesses of the various fire suppression agents and systems. Based on this understanding the student should be able to put forth alternative strategies that may be used to provide a reasonable level of protection in a particular hazard.

While plain water and automatic sprinkler systems are recognized as the most common and basic system protection, and is an extremely effective extinguishing agent, there are times when additional protection is desired, or when water is not available or is not suitable. Non-suitability arises in cases when it is necessary to minimize water damage, the material may react with water, or because of clean-up problems after the fire.

When problems such as the above arise there are a number of chemical agents in fire protection technology that may be chosen, either singularly or in combination, to ensure that fire suppression may be achieved in the most efficient manner.

Even when the protection of a special hazard may justify the installation of a special suppression system, it should be noted that automatic sprinkler protection is still generally needed for life safety and exposure protection.
