For which type of occupancy can sidewall sprinklers be specifically listed and installed?

Sidewall sprinklers are specifically listed for use in light hazard occupancies due to their design and application characteristics. These sprinklers are engineered to provide effective coverage in areas where the fire risk is minimal compared to high hazard situations, such as industrial environments.

In light hazard occupancies, the arrangement of furnishings and the space configuration typically allow for effective water distribution from sidewall sprinklers, which can be mounted on the walls. These sprinklers are particularly beneficial in protecting areas such as storage rooms or small office spaces, where overhead obstructions may limit the use of standard pendant sprinklers.

While sidewall sprinklers can occasionally be utilized in residential and commercial occupancies, it’s important to note that their listing and application are primarily aimed at meeting the needs specific to light hazard environments, thereby ensuring appropriate fire protection based on the occupancy classification and associated risks.
