Fire proof rating

8/15/2020

 
The fire proof system can be divided into two aspects, these are passive and active protection.
Active fire protection - manual and automatic detection and suppression of fires,
For example:
Fire or smoke detector system
Fire alarm systems.
Fire sprinkler systems
Fire extinguisher
Firefighter
Passive fire protection (PFP) - The installation of fire rated walls, ceiling and floor assemblies to form fire compartments intended to limit the spread of fire, high temperatures, and smoke.
For example:
To improve fire resistance performance of material
To paint the fire-retardant coating, such as cementitious and epoxy intumescent.
To cover the insulated panel

Fire Testing
For PFP materials to be classified for offshore use they must meet three main fire-testing requirements that are commonly accepted. These are Standard fire test, Hydrocarbon pool fire test and Hydrocarbon jet fire test.
 
Fire proof classification according to Standard Fire test
There are three classification which are A, B and C class.
1. "A" class divisions:
1). They are constructed of steel or other equivalent material;
2). They are suitably stiffened;
3). They are constructed as to be capable of preventing the passage of smoke and flame to the end of the one-hour standard fire test;
4). They are insulated with approved non-combustible materials such that the average temperature of the unexposed side will not rise more than 140ºC above the original temperature, nor will the temperature, at any one point, including any joint, rise more than 180ºC above the original temperature, within the time listed below:
     Class "A-60”   60 min
     Class "A-30”   30 min
     Class "A-15”   15 min
     Class "A-0”      0 min
2. "B" class divisions:
1). They are constructed of approved non-combustible materials and all materials used in the construction and erection of "B" class divisions are non-combustible, with the exception that combustible veneers may be permitted provided they meet other appropriate requirements of this chapter;
2). They are constructed as to be capable of preventing the passage of flame to the end of the first half hour of the standard fire test;
3). They have an insulation value such that the average temperature of the unexposed side will not rise more than 140ºC above the original temperature, nor will the temperature at any one point, including any joint, rise more than 225ºC above the original temperature, within the time listed below:
     Class "B-15"    15 min
     Class "B-0"       0 min
3.  "C" class divisions 
Divisions constructed of approved noncombustible materials. They need meet neither requirements relative to the passage of smoke and flame nor limitations relative to the temperature rise.

Fire proof classification according to Hydrocarbon Pool Fire test
"H" class divisions:
1. They are constructed of steel or other equivalent material;
2. They are suitably stiffened;
3. They are constructed as to be capable of preventing the passage of smoke and flame to the end of the two-hour standard fire test;
4. They are insulated with approved non-combustible materials such that the average temperature of the unexposed side will not rise more than 140ºC above the original temperature, nor will the temperature, at any one point, including any joint, rise more than 180ºC above the original temperature, within the time listed below:
     Class "H-120”    120 min
     Class "H-60”       60 min
     Class "H-0”          0 min

Fire proof classification according to Hydrocarbon Jet Fire test
"J" class divisions:
1. They are constructed of steel or other equivalent material;
2. They are suitably stiffened;
3. They are constructed as to be capable of preventing the passage of smoke and flame to the end of the first half hour standard fire test;
4. They are insulated with approved non-combustible materials such that the average temperature of the unexposed side will not rise more than 140ºC above the original temperature, nor will the temperature, at any one point, including any joint, rise more than 180ºC above the original temperature, within the time listed below:
     Class "J-60”    60 min
     Class "J-30”    30 min
