If high-temperature sprinklers are used, the coverage area will be 4,000 sq. ft: False.
A sprinkler can be defined as a mechanical device with a lot of small holes that is typically attached to the end of a hose, in order to put off flames or fire by spraying water at the burning physical object or structure.
According to the report by the National Fire Protection Association, we can infer and logically deduce that it is false to state that the coverage area will be 4,000 square feet (3720square meters) when high-temperature sprinklers are used.
In conclusion, the coverage area per sprinkler head for areas with a high concentration of flammable materials (extra hazard 1 & 2) is 90 - 130 square feet.
