Active protection systems tank fires

For means of protection, the use of water based suppression systems may be a hazard due to the disposal of firewater water, which will freeze quite readily in exposed locations. This may also be the case with exposed hydrocarbon fluid lines that, if isolated, say for an ESD activation, may freeze up due to lack of circulation. This will hamper restart operations for the facility. Typical use in the past has been the reliance on gases fire suppression agents for enclosed area, particularly Halon. Other methods include fire water storage tanks that are kept warm, together with fire mains deeply buried and continually circulated. 

If trained to do so and confident that you are capable, activate any fire monitors and/or fixed fire water systems in the immediate area and attempt to cool the tank and surrounding equipment. If the tank is receiving material or product, close a valve on the inlet line at a safe location. Stand by to direct the Emergency Response Team (ERT) to scene Use appropriate Personal Protective Equipment (PPE) First Responder... 

The principal focus of this book is the mitigation of accidental releases of toxic or flammable materials throu release countermeasures, in particular, postrelease systems. Postrelease systems are designed for control of a hazardous material once it has been released into the environment. Control measures can include passive systems, such as dikes or berms around storage tanks, as well as active methods, such as water-spray or deluge systems installation around a process unit, or q>plication of foam on a chemical spill. However, fire fighting, blast protection and environmental control of response methodolo es are not covered in this guideline.
