You first start with the Fire Code adopted in the community. The fire code has requirements for flammable and combustible liquids and also includes fire protection requirements. You have to start there. The IFC varies from NFPA 30 in some sections. There are maximum allowable quantities (MAQ's) and other requirements.

Often they are mislabeled due to people only looking at the flash point and not at the boiling point of the liquid. In cosmetics 1B is common. You need to know exactly what the material is. Request a SDS on the material. NFPA doesn't get into comparing quantities to sprinkler design. You need to know what it is, how much there is, what kind of container is it in, is it just stored or is there any dispensing of the product, is it stored on the floor or on racks. What does the SDS indicate as far as approved firefighting methods. Do these areas handling the 1B and potentially 1A have secondary containment of the spilled material within the room (pool fire) or is it evacuated out of the area? Those are the opening questions.
