Fire Fighting Hazards Classification : Occupancy hazard classification is the most critical aspect of the sprinkler system design process .
 |
| Fire Fighting Hazard Classification |
If the hazard is underestimated, it is possible for fire to over power the sprinklers (resulting in a large loss of property or life )
The classification of Fire Fighting hazard varies according to the commodities and application of the project .
- Light Hazard
- Ordinary Hazard Group (1)
- Ordinary Hazard Group (2)
- Extra Hazard Group (1)
- Extra Hazard Group (2)

Fire Fighting Light hazard occupancies shall be defined as occupancies or portions of other occupancies where the quantity and / or combustibility of contents is low and fires with relatively low rates of heat release are expected .
Fire Fighting Ordinary Hazard (group 1)

| Fire Fighting ordinary Hazard group 1 |
Fire Fighting Ordinary hazard ( group 2 )

| Fire Fighting ordinary Hazard group 2 |
Occupancies shall be defined as occupancies or portions of other occupancies where the quantity and combustibility of contents are moderate to high
Stockpiles do not exceed 12 ft (3.7 m) and fire with moderate to high rates of heat release are expected
Stockpiles do not exceed 12 ft (3.7 m), and fires with moderate to high rates of heat release are expected.

Fire Fighting Extra hazard (group 1)
 |
| Fire Fighting Extra Hazard |
Extra hazard (group 1) occupancies shall be define as occupancies or portions of other occupancies where the quantity and combustibility of contents are very high and dust, lint, or ohet material are present, introducing the probability of rapidly developing fire with high rates of heat release but with little or no combustible or flammable liquid.

Fire Fighting Extra hazard (group 2)
 |
| Fire Fighting Extra Hazard group 2 |
Extra whazard (group 2) occupancies shall be defined as occupancies or portions of other occupancies with moderate to substantial amounts of flammable or combustible liquids or occupancies where shielding of combustibles is expensive.
