The ADR-4.1. class

 

 

Highly flammable solid substances

 

Class 4.1 embraces the highly flammable substances and articles, desensitized explosives which are solid substances and self-reactive liquids or solids. Highly flammable solid substances are substances that capable of be inflamed easily and hard substances that are capable of starting the flame during the friction. The flammable solid substances may be of the powder, granules, or paste-like forms that may be considered hazardous if they can inflame easily during the short-time contact with the source of the inflammation like the burning match and if the flame is spread fast. Not only may the flame be a source of hazard but the toxic combustion products, too. Metal powders are particularly dangerous as it is difficult to extinguish the flame in this case because conventional fire extinguishing agents such as carbon dioxide or water can even increase the hazard.

 

 

 

 

 

 

 

 

The symbol (flame) is black on the white background with seven vertical red lines, number “4” is located in the bottom corner.

 

 

 

Additional information about the sub-class

 

 

Solid desensitized explosive substances are substances that are soaked with water or dissolved in spirits or other liquid substances to suppress their explosive properties. Self-reactive substances are thermally unbalanced substances that may be an object of flamboyant chemical exothermic decomposition even without the oxygen or air during the reaction. Some self-reactive substances can be transported only in conditions when the temperature is controlled. In order to ensure safety during the transportation, self-reactive substances are in many cases desensitized by dissolvent.

 

 

 

The ADR-4.2 class

Substances capable of self-inflammation

The ADR-4.2 class embraces:

• Self-heating substances and items – these are ones, including mixtures and solutions that may heat-up by oneself with the air contact without consuming the outside energy. These ones are flammable only in big quantities (kilograms) and only within long time periods (hours or days). The reason of self-heating is the chemical reaction of the substance with oxygen contained in the air when the heat from the reaction is transported not fast enough in the outside environment.

The symbol (flame) is black on the white background at the top and the red background at the bottom, number “4” is located in the bottom corner.

Additional information about the sub-class

The symbol (flame is above the circle) is black on the yellow background, numbers “5.2.” are located in the bottom corner.

 

 

 

Additional information about the sub-class

 

Organic peroxides are prone to exothermic decomposition in the normal and high temperature. Decomposition may start under the influence of heat, contact with admixtures (like acids, heavy metals compositions, and amines), friction or a stroke. The speed of decomposition increases as the temperature increases and is dependent on the contents of the organic peroxide. Decomposition may lead to the occurrence of pernicious or flammable gasses or steams. Some organic peroxides must be transported only if the temperature is regulated. Some organic peroxides may dissolve with an explosion, especially in the closed space. This may be changed if the solvents are added or the appropriate containers are used. Many organic peroxides burn extensively. You must avoid the hit of organic peroxides in your eyes. Some organic peroxides may cause the heavy trauma of the cornea or to dissolve the skin even during the short contact. Organic peroxides are divided into 7 types according to the hazard they represent. Organic peroxides are ranged from A type – peroxides that are disallowed to be transported in the container in which they are tested to G type – peroxides that are not embraced by the requirements of the 5.2 class.
