Final answer:
Early Suppression Fast-Response (ESFR) sprinkler heads are typically located in high-rack storage areas of warehouses and distribution centers to quickly suppress high-challenge fires. They discharge water at high pressures, are mounted in the ceiling, and are designed according to the facility's specific storage and ceiling parameters.
Step-by-step explanation:
An Early Suppression Fast-Response (ESFR) sprinkler head is a type of fire sprinkler system designed to suppress high-challenge fires quickly. ESFR heads are often found in locations with high-rack storage, such as warehouses and distribution centers. Their ability to discharge a significant quantity of water at very high pressure makes them suitable to put out fires in environments where goods are stacked high and a conventional sprinkler system would not be adequate to control a fire before it spreads.
These sprinkler heads are usually installed in the ceilings of the facilities and can be identified by their large, bulbous design compared to standard sprinkler heads. They are placed at specific intervals to provide optimal coverage in case of fire. The design of an ESFR system depends on various factors including the type of commodities being stored, the storage arrangements, and the ceiling height of the facility.
