What does NFPA 13 specify regarding sprinkler installation in flammable liquids storage areas?

NFPA 13 highlights the importance of carefully considering the unique risks associated with flammable liquids when designing sprinkler systems. The correct answer emphasizes that sprinkler systems in areas where flammable liquids are stored must be specifically designed to address potential liquid spills, which helps to contain and control fire hazards.

This includes considerations for the placement, type of sprinkler, and discharge patterns to ensure effective performance in case of a fire. The standard requires that the installation provides adequate environmental protections to mitigate the risk of fire and environmental contamination. This proactive approach is essential for the safety of occupants and the protection of property.

In contrast, the other options suggest a laxity or a lack of specificity that does not align with the requirements of NFPA 13. For example, stating that standard units can be used without special considerations fails to recognize the higher risks associated with flammable liquids. Similarly, claiming that installation is optional undermines the critical need for fire protection in these hazardous areas. Lastly, indicating that only foam-based sprinklers are allowed is misleading, as NFPA 13 accommodates various approaches depending on the specific circumstances surrounding the storage of flammable liquids.
