What does a triangle symbol indicate regarding combustibles?

The triangle symbol is used to signify the presence of ordinary combustibles. This designation typically pertains to materials that can readily ignite and sustain combustion but do not pose the same level of immediacy or danger as flammable materials, which might ignite more easily or burn much more intensely. Ordinary combustibles include paper, wood, cloth, and some types of plastics. These materials can catch fire under certain conditions, particularly in the presence of an ignition source.

The triangle acts as a visual cue, guiding individuals in safety contexts to identify and assess risks associated with these types of materials. In environments like warehouses, manufacturing facilities, or any setting involving potentially hazardous materials, recognizing the significance of symbols like the triangle can contribute to maintaining safety standards and preventing fire-related incidents.
