We see this from time to time: someone drills a hole in the flammable liquids storage cabinet (a major no-no) and runs a power cord inside the cabinet (another no-no), and this electrical device can pose as an ignition source. So, the 2024 IFC added the following requirement.
NOTE: This requirement should NEVER be needed, as we should NEVER drill into our UL/FM-approved cabinet, much less add lighting or any other ignition sources inside the cabinet.
