Which of the following statements about spare sprinklers is true?

The correct statement about spare sprinklers is that a minimum of 6 is needed for small facilities. This requirement is based on best practices to ensure that a facility is adequately equipped for maintenance and emergency replacements. Having spare sprinklers allows for quick replacement in the event of a malfunction or damage, ensuring that the fire protection system remains operational without delay.

When assessing the needs of different facility sizes, small facilities generally have a set standard for the number of spare sprinklers required to effectively manage potential repairs and maintain compliance with safety regulations. This is important for the ongoing safety of the building and its occupants.

Other choices do not reflect the established fire protection guidelines. For instance, suggesting only 4 are needed for any facility size does not consider the variable nature of different facility sizes and requirements. Claiming there is no need for spare sprinklers overlooks the essential role they play in the reliability of fire suppression systems. Lastly, stating that all facilities require 12 spare sprinklers can lead to over-preparation or unnecessary costs, especially for small facilities that don't require such a large inventory of spares.
