Requirements for updating fire suppresion system
These tanks are not allowed to be refilled and put back into service because they do not comply with UL-300.
Manufacturers also do not supply replacement parts for these systems.
To provide an automatic spray of water to control a fire, sprinkler systems were developed in the late 19th century.
Since then, automatic sprinklers have become the most common fixed fire suppression system for providing fire safety in buildings.
UL-300 is a kitchen fire suppression standard developed by Underwriters Laboratories (UL).
Total flooding means applying an extinguishing agent to a three-dimensional enclosed space in order to achieve a concentration of the agent adequate to extinguish the fire.Sprinklers control fire development by wetting and cooling the fuel surface.They are effective for fires involving solid materials (referred to as solid fuels) but are not effective for flammable liquids (called liquid fuels) such as gasoline, diesel and jet fuels.These types of systems may be operated automatically or manually.Local application means applying an extinguishing agent directly onto a fire (usually a two-dimensional area), or into the three-dimensional region immediately surrounding the substance or object on fire.
