Does a hospital need to have sprinklers in walk-in boxes and/or freezers in order to be considered fully sprinklered?
Yes. Although it is not always cited as an issue, in order to state that a building is fully sprinklered, it must have sprinklers in the walk-ins. The code reference is K-tag # K056 taken from NFPA 101 section 19.3.5.
2000 NFPA 101 LSC Chapter
19.3.5 Extinguishment Requirements.
19.3.5.1 Where required by 19.1.6, health care facilities shall be protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7.
9.7 AUTOMATIC SPRINKLERS AND OTHER EXTINGUISHING EQUIPMENT
9.7.2 Supervision.
9.7.2.1* Supervisory Signals.
Where supervised automatic sprinkler systems are required by another section of this Code, supervisory attachments shall be installed and monitored for integrity in accordance with NFPA 72, National Fire Alarm Code, and a distinctive supervisory signal shall be provided to indicate a condition that would impair the satisfactory operation of the sprinkler system. Monitoring shall include, but shall not be limited to, monitoring of control valves, fire pump power supplies and running conditions, water tank levels and temperatures, tank pressure, and air pressure on dry-pipe valves. Supervisory signals shall sound and shall be displayed either at a location within the protected building that is constantly attended by qualified personnel or at an approved, remotely located receiving facility.
