How many spare sprinklers are required for facilities with less than 300 sprinklers?

In facilities with fewer than 300 sprinklers, the standard practice is to maintain a specific number of spare sprinklers to ensure system reliability and minimize downtime in case of failures or maintenance needs. According to the relevant codes and standards, the requirement is typically to have at least 6 spare sprinklers readily available. This guideline ensures that there are enough replacement units on hand to address potential sprinkler defects or damages without significantly impacting the system's performance.

Having 6 spare sprinklers allows for prompt repairs and helps maintain the operational integrity of the sprinkler system, which is crucial for fire safety in any facility. This practice aligns with national safety regulations, which emphasize preparedness for unexpected equipment failures. Thus, the correct answer is based on established industry standards that support effective fire protection management in such facilities.
