a material that is a flammable solid would
Definitions: Solid materials that pose a serious risk of fire in uncontrolled conditions. The hazard class is divided into three broad categories. Subsets of class 4 are: 4.1 Flammable Solids are readily combustible, or may contribute to a fire through friction. 4.2 Spontaneously Combustible materials (also called substances liable to spontaneous combustion) are liable to spontaneous generation of heat during transportation which can then lead to a fire. FLAMMABLE SOLID. A solid, other than a blasting agent. or explosive, that is capable of causing fire through friction, absorption or moisture, spontaneous chemical change, or. retained heat from manufacturing or processing, or which has. an ignition temperature below 212°F (100°C) or which burns. § 173.124 Class 4, Divisions 4.1, 4.2 and 4.3 - Definitions. ( 1 a)Division 4.1 (Flammable Solid). For the purposes of this subchapter, flammable solid (Division 4.1) means any of the following three types of materials: ( 2 b)Division 4.2 (Spontaneously Combustible Material). A chemical shall be considered a flammable solid. as determined in accordance with the test method of CPSC 16. CFR; Part 1500.44, if it ignites and burns with a self-sustained. flame at a rate greater than 0.1 inch (2.5 mm) per second along. its major axis. Flammable solids are any materials in the solid phase of matter that can readily undergo combustion in the presence of a source of ignition under standard circumstances, i.e. without: 1  Artificially changing variables such as pressure or density; or. 2  Adding accelerants. Subsets of class 4 are: 1  4.1 Flammable Solids are readily combustible, or may contribute to a fire through friction. These include: 2  Flammable solids. 3  Self reactive substances.  Solid desensitized explosives. Flammable materials can be found as solids, liquids, or gases. Flammable solids can be classified in three categories: desensitized explosives, self-reactive materials, and readily combustible solids. These are generally non-explosive but may ignite when exposed to friction, moisture, heat retained from processing, or a spontaneous chemical change. Refrigerators: Do not use domestic refrigerators/freezers for flammable or combustible liquid storage. The internal components could cause a spark and ignite the contents. Make sure the unit is explosion-proof or laboratory safe and indicate that it is to be used for flammable material only. HAZMAT Class 4 Flammable solids. Flammable solids are any materials in the solid phase of matter that can readily undergo combustion in the presence of a source of ignition under standard circumstances, i.e. without: Artificially changing variables such as pressure or density; or. § 173.124 Class 4, Divisions 4.1, 4.2 and 4.3 - Definitions. (a)Division 4.1 (Flammable Solid). For the purposes of this subchapter, flammable solid (Division 4.1) means any of the following three types of materials: (1) Desensitized explosives that -.
