Fire fighting, the boiler room in our unit uses a biomass boiler, which is the kind that burns particles. Do you need to post a sign prohibiting fireworks and firecrackers at the door of the boiler room? The boiler room is burning solid particles, which belongs to the area with frequent open flames, and there is no need to post a sign prohibiting the discharge of fireworks and firecrackers; However, this area belongs to open flame and high temperature area, so it should be marked with open flame area, and the room should not be filled with flammable and combustible materials, and should keep a sufficient fire distance from other buildings and structures.
