How many spare stock sprinklers should be maintained for larger systems exceeding 300 sprinklers?

The requirement to maintain a certain number of spare stock sprinklers for larger systems is crucial for ensuring operational readiness in case of immediate replacement needs. For systems exceeding 300 sprinklers, the recommendation to keep at least 6 spare sprinklers provides a practical balance between accessibility and inventory management.

Having at least this number of spare sprinklers allows a facility to quickly address any sprinkler failures without delaying operations for repairs or replacements. It ensures that the fire protection system remains functional and compliant with safety regulations, thereby minimizing risks in the event of a fire.

Larger systems are complex, and while it's essential to have a contingency plan for sprinkler replacement, not overstocking is also a consideration to avoid unnecessary costs or space usage. The choice of a minimum of 6 reflects industry standards and practices that align with typical needs for maintenance and emergency situations.
