In what types of groups must quick-response or residential automatic sprinklers be installed?

Quick-response or residential automatic sprinklers are designed to operate effectively in a variety of occupancy types where life safety and property protection are critical. The installation of these sprinklers is particularly vital in Group I-2 (which includes medical facilities like hospitals), Group R (which encompasses residential occupancies such as apartments and college dormitories), and light hazard occupancies (which could include areas with a limited fire load).

For Group I-2, the need for rapid response sprinklers is essential due to the presence of vulnerable populations and the potential for increased risks associated with fires in healthcare settings. In Group R, these sprinklers enhance the safety of residential occupants by quickly controlling fires, reducing the chance of a small fire spreading and creating a hazardous situation. Light hazard occupancies benefit from the quick-response nature of these sprinklers as they serve to mitigate risks associated with lower fire loads, ensuring the safety of occupants and reducing property damage.

Given the significant role that automatic sprinklers play across these various occupancy types, the correct choice reflects the fact that quick-response and residential sprinklers should indeed be installed in all of these groups to maximize protection and safety. This comprehensive requirement ensures that buildings of different types can effectively manage fire hazards, leading to better outcomes in the event of
