D.O.T. Spontaneously Combustible Label for Hazardous Materials
Hazard Class 4 Transportation Label
This D.O.T. Spontaneously Combustible 4 label clearly identifies potential hazards like military munitions in a familiar design. This 4 inch X 4 inch, Department of Transportaion shipping label conveys hazard information for containers or shipments of hazardous materials. The bright red and white background with black text on top and the fire graphic cleary communicates "SPONTANEOUSLY COMBUSTIBLE". Flexible label stock with permanent adhesive. Printed with UV-stable ink and issuitable for indoor or outdoor use at service temperatures from -40 F to +180 F.

4.2 Spontaneously Combustible: Solid substances that ignite spontaneously (aluminium alkyls, white phosphorus). These include oligomerization of ethylene, dimerization and cyclodimerization of olefins and dienes, and ring opening polymerization. White phosphorus (WP) is a material made from a common allotrope of the chemical element phosphorus that is used in smoke, tracer, illumination and incendiary munitions.
This Department of Transportation SPONTANEOUSLY COMBUSTIBLE label is very often referred to as an Accuform brand with the part number of MSL201EV5
Division 4.2: Flammable Solids
Flammable solids are any of the following three types of materials:
Desensitized Explosives: explosives that, when dry, are Explosives of Class 1 other than those of compatibility group A, which are wetted with sufficient water, alcohol, or plasticizer to suppress explosive properties; and are specifically authorized by name either in the 49CFR 172.101 Table or have been assigned a shipping name and hazard class by the Associate Administrator for Hazardous Materials Safety.
Self-Reactive Materials: materials that are thermally unstable and that can undergo a strongly exothermic decomposition even without participation of oxygen (air). Certain exclusions to this group do apply under 49 CFR.
Generic Types: Division 4.1 self-reactive materials are assigned to a generic system consisting of seven types. A self-reactive substance identified by technical name in the Self-Reactive Materials Table in 49CFR 173.224 is assigned to a generic type in accordance with that Table. Self-reactive materials not identified in the Self-Reactive Materials Table in 49CFR 173.224 are assigned to generic types
Readily Combustible Solids: materials that are solids which may cause a fire through friction, such as matches; show a burning rate faster than 2.2 mm (0.087 inches) per second when tested in accordance with UN Manual of Tests and Criteria; or are any metal powders that can be ignited and react over the whole length of a sample in 10 minutes or less, when tested in accordance with UN Manual of Tests and Criteria.
Type
Description
Type A
Self-reactive material type A is a self-reactive material which, as packaged for transportation, can detonate or deflagrate rapidly. Transportation of type A self-reactive material is forbidden.
Type B
Self-reactive material type B is a self-reactive material which, as packaged for transportation, neither detonates nor deflagrates rapidly, but is liable to undergo a thermal explosion in a package.
Type C
Self-reactive material type C is a self-reactive material which, as packaged for transportation, neither detonates nor deflagrates rapidly and cannot undergo a thermal explosion.
Type D
Self-reactive material type D is a self-reactive material which: • Detonates partially, does not deflagrate rapidly and shows no violent effect when heated under confinement;
• Does not detonate at all, deflagrates slowly and shows no violent effect when heated under confinement; or • Does not detonate or deflagrate at all and shows a medium effect when heated under confinement.
Type E
Self-reactive material type E is a self-reactive material which, in laboratory testing, neither detonates nor deflagrates at all and shows only a low or no effect when heated under confinement.
Type F
Self-reactive material type F is a self-reactive material which, in laboratory testing, neither detonates in the cavitated state nor deflagrates at all and shows only a low or no effect when heated under confinement as well as low or no explosive power.
Type G
Self-reactive material type G is a self-reactive material which, in laboratory testing, does not detonate in the cavitated state, will not deflagrate at all, shows no effect when heated under confinement, nor shows any explosive power. A type G self-reactive material is not subject to the requirements of this subchapter for self-reactive material of Division 4.1 provided that it is thermally stable (self-accelerating decomposition temperature is 50°C (122°F) or higher for a 50 kg (110 pounds) package). A self-reactive material meeting all characteristics of type G except thermal stability is classed as a type F self-reactive, temperature control material.
Spontaneously combustible material is:
Pyrophoric Material: A pyrophoric material is a liquid or solid that, even in small quantities and without an external ignition source, can ignite within five (5) minutes after coming in contact with air when tested according to the UN Manual of Tests and Criteria.
Self-Heating Material: A self-heating material is a material that, when in contact with air and without an energy supply, is liable to self-heat.
