According to NFPA 13, what is required for spare stocker sprinklers?

The requirement for spare stocker sprinklers under NFPA 13 is that they must undergo quarterly inspections. This ensures that these sprinklers are kept in proper working condition and can be readily available for use in the event of a fire. Regular inspections help to identify any potential issues, such as corrosion, physical damage, or other deterioration that might compromise their functionality.

The frequency of inspections is important because it balances the need for readiness with practical maintenance considerations. Quarterly inspections provide a consistent review process without being overly burdensome, which helps ensure safety in high-rise buildings. Regular checks can thus prevent system failures due to neglected maintenance, supporting overall fire safety in facilities.
