Fire Prevention and Fire Protection
"Protecting Production - Saving Lives"
The science of Fire Prevention and Fire Protection has three goals:
Continuity of operations
The Fire Triangle
Fire protection is based on the Fire Triangle and controlling the fuel, oxygen, and ignition.
The Process Industries
In the process industries, the fuel is typically Combustible Dust, and to prevent fires and deflagrations you must control fugitive dust emissions and ignition sources.
Fire and Explosion Prevention and Protection Systems are designed around managing RISK.
Risk management as defined here is about controlling the probability of occurrence, and the magnitude or the severity of a fire or deflagration event.
Thus active Prevention systems are used to reduce the probability of occurrence of a fire or deflagration.
Protection systems are reactive, and thus designed to manage the risk of the event once it occurs.
Layered Protection is based on several stages of safety system design:
1) Fire Prevention
2) Fire Protection
3) Explosion Prevention
4) Explosion Protection
With each layer of protection designed to prevent of manage another layer of risk. Each layer of protection is designed to mitigate, separate, or isolate the risk from the rest of the process.
Stage 1) Fire Prevention
FIRE PREVENTION is based on various Hazard Monitoring Systems that include but are not limited to:
Spark Detection and Extinguishing Systems, including spark, ember, black body, smoke and flame detection
Bearing temperature, belt alignment, plug-up detection systems
Linear heat detection
Rate of rise heat detection
Combustion Gas detection
Video smoke and flame detection
And various other complimentary detection systems designed to detect and prevent fires in the incipient stage. Various types of detectors can be mounted on conveyors, transitions, ductwork, in the production area, and on production equipment itself to monitor hazards and alert operators, as well as interlocking various types of alarms, suppression and deluge systems, machinery shutdown, etc. And various levels of alarms can be interlocked depending on the threat level.
Fire prevention is based on active monitoring systems designed to detect the first signs of combustion, and react to prevent the incipient fire from developing.
Stage 2) Fire Protection
FIRE PROTECTION systems include but are not limited to:
Water sprinkler and deluge systems
Water Mist systems
Fire Protection systems are reactive and designed to suppress a fire once developed, and prevent further risk to life and property.
