Fire in a storage tank, or in the surrounding bund, is a challenge to both fire fighters and tank operatorsThe value of the contents makes the provision of fire protection commercially viable, while the risk to life makes it essentialThe fire protection options available to

Sumair (Chemical) (OP) Jul I have been given the task of designing a fire protection system for fixed roof fuel oil storage tanksTank details are as follows Diameter = mHeight = mProduct = Fuel Oil (Class III) Flashpoint = C and above.

Standards of Fire Protection System NFPA (National Fire Protection Association) decides tank fire protection guidelines in the USAThese include specifications of foam delivery layout, rates and spacingThe contents of the tank fix the foam application rates that range between liters m min to liters m min.

computer systemStorage of fuel is restricted to Cat Class DG onlyThe enclosure walls and the entrance doors of the FTR(s) should have at least hour and hour Fire Resisting Period (FRP) respectively

wing tank only versus inerting all of the aircrafts fuel tanksFinally, two methods of purging oxygen from the tank were reviewed i.escrubbing the fuel and washing the ullage space above the fuelA ground based system provides the potential for the least

DONTs Siting of FTR(s) shall not jeopardize any means of escapeAggregate quantity of the fuel oil in FTR(s) on the same floor shall not exceed , litresPiping connecting fuel tank(s) and or generator set(s) shall not pass through any means of

RE Oil storage tank water protectionlekshmi (Mechanical) Apr NFPA indicates that tanks located as per Section does not need any cooling systemWe generally do a heat radiation study considering fuel characteristics, height of tank, location w.r.t other tanks and wind velocity.

The rising foam can cause the fuel in the tank to circulate which can assist in cooling the fuel at the surface If there is an explosion and fire that could damage the top of the tank, the sub surface injection system is not likely to suffer damage directed to

NFPA Fuel Tank Arrangement The fuel tank is sized for liter kW ( gal HP) plus ( for expansion and for sump)The fuel tank shall be reserved exclusively for the fire pump diesel engineThere shall be one fuel tank per engine.

Passive Protection Disallowing fire fighting activities and ensuring the stored fuel is allowed to burn out without any interventionDefensive Cooling the surrounding exposures (this includes tanks, process equipment, and structures) to prevent escalation and allow the tank to burn out.
