Are obstructions such as baffle plates or shelves allowed in the spray pattern of an automatic fire extinguishing system?

The practice of ensuring that an automatic fire extinguishing system operates effectively is critical in commercial cooking operations. Obstructions such as baffle plates or shelves in the spray pattern of an automatic fire extinguishing system can inhibit the system’s ability to distribute extinguishing agents evenly and effectively over the area needing protection, which is essential during a fire.

The NFPA 96 Standard emphasizes that obstructions should not interfere with the spray pattern of these systems. Maintaining a clear pathway for the extinguishing agent allows for optimal coverage and increases the chances of successfully suppressing a fire quickly. Therefore, having obstructions present can significantly compromise the fire protection measures in place, making it necessary to prohibit them.

This strict requirement ensures that the systems are able to provide the best possible protection during a fire incident, as any interference could lead to failure in extinguishing the flames promptly. Thus, the answer that states obstructions are not permitted aligns with the safety protocols established within NFPA guidelines.
