The effectiveness of ESFR (Early Suppression, Fast Response) sprinklers in suppressing fires involving plastics is attributed to their design and operational characteristics. These sprinklers activate at a higher temperature compared to standard sprinklers, allowing them to respond more quickly to fires with a greater heat release rate, which is a common characteristic of plastic fires.

ESFR sprinklers are engineered to deliver a large water discharge rate over a wide coverage area, which is critical when facing the rapid ignition and burning characteristics associated with plastics. They are particularly beneficial in warehouse settings where plastics may be stored in high-piled storage arrangements. Their quick activation and ability to discharge significant amounts of water make them suitable for situations where fire dynamics can change rapidly, thereby suppressing the fire efficiently before it can grow.

In contrast, standard sprinklers may not provide the same quick and robust suppression needed for plastic fires due to their lower water discharge rates and slower response times in high-heat conditions. Deluge sprinklers are typically used in special applications, such as in paint spray booths or where highly flammable materials are stored, and they release water continuously without individual activation, which might not effectively target localized plastic fires. Wet pipe sprinklers, while commonly used, may not have the specific design
