How many additional sprinkler heads should be kept available on the premises to replace any damaged or fused ones?

Maintaining additional sprinkler heads on the premises is critical for ensuring the effective performance of a fire suppression system. Keeping at least six extra sprinkler heads available is a practical approach that aligns with standard safety practices. This quantity ensures that there are sufficient replacements in the event of any damage or malfunction, enabling prompt repair and maintaining compliance with fire safety regulations.

Having six extra heads allows for flexibility across multiple locations and potential incidents. It supports quick action in restoring the fire protection system to full operational status, minimizing downtime and potential fire hazards. This readiness can be crucial, especially in environments where fire risks are significant, as it enhances overall safety and preparedness.

In comparison, while higher numbers may seem more secure, the requirement for at least six strikes a balance between preparedness and practical storage capabilities within the premises. Ensuring that sufficient parts are readily available helps to maintain the integrity of the fire life safety system, ultimately protecting the building occupants and property.
