NFPA 13 does not specifically require sprinkler shields in electrical rooms. However, the AHJ may have specific requirements for sprinkler shields in electrical rooms based on their local code or interpretation of NFPA 13.One possible reason for the AHJ's requirement for sprinkler shields is to protect the sprinkler heads from damage in the event of an electrical fire. Sprinkler heads are typically made of glass or plastic, which can be easily damaged by heat or falling debris. A sprinkler shield can help to protect the sprinkler head from damage, ensuring that it will operate properly in the event of a fire.Another possible reason for the AHJ's requirement for sprinkler shields is to prevent the spread of fire through the sprinkler system. In the event of a fire, the sprinkler system will discharge water into the room. If the sprinkler heads are not shielded, the water can spread the fire to other areas of the room. A sprinkler shield can help to prevent the spread of fire by containing the water within the sprinkler head's discharge area.If you are unsure why the AHJ is requiring sprinkler shields in your electrical rooms, you should contact them for clarification. They will be able to provide you with the specific reasons for their requirement and explain how it applies to your specific situation. Flag for review
