E F G There is no detonation and a slow deflation occurs; It does not show a severe effect when heated under closed conditions. There is no detonation or deflagration and it has a moderate effect when heated under closed conditions. There is no detonation or deflagration and it has a low severity when heated under closed conditions. Laboratory tests do not result in detonation in cavitation where air bubbles are formed in the liquids, there is no deflagration; it has a very low effect or does not show at all. In laboratory tests, cavitation detonation does not occur when air bubbles are formed in liquids, there is no deflagration; it does not show any effect when heated under closed conditions. They are thermally stable (SADT 60 oC or higher for a 50 kg package). The substance may be thermolabile or may be type F if diluted with a diluent with a boiling point of less than 150 oC. Type A Organic peroxides is prohibited to transport and other classes are subject to the transport regulations except for Class G. The organic peroxides are assigned UN numbers as shown in Table 2 according to their physical properties and temperature control properties.

In transport functions of organic peroxides on land or in the sea, the general transport regulations are determined by ADR (land) and IMDG Code (sea). In the transport of dangerous goods, the substances are divided into different categories according to the hazard classes. Organic peroxides are listed in class 5.22 and the transportation symbol is as follows: Figure 1: Hazard Symbol of Organic Peroxides in Transport Elements that can initiate decomposition in organic peroxides In general, a several problems may arise during the storage, transport and handling of organic peroxides. The initiating elements that can cause major accidents in these processes usually occur with the following effects and the mentioned precautions should be taken: - Heat access to initiate uncontrolled degradation: Sunlight, contact with hot surfaces, high ambient temperature: It should be kept away from all sources of heat. - Not spreading enough heat around at any temperature increase, the presence of unneeded materials in the stacking area and in materials that will disrupt air circulation: Storing and stacking organization should be done in such a way as not to obstruct air circulation. - If any impurities is mixing that will serve as a catalyst: A deep cleaning, ordering procedure should be applied and kept away from incompatible materials. - Mechanical shocks and friction: It must be protected from impact, jolt, crashing, jamming, falling and friction. These effects can cause immediate explosion or combustion. - Large packaging volume: Packaging should be used as low volume as possible. - Storage of organic peroxides over recommended shelf life over extended periods of time: Shelf life recommendations of the manufacturer should be followed in storage. Excessive standby increases distortion. - External fires: The products must be protected against fire that may come from external ignition sources. - Special caps should be used in packaging: A ventilation caps should be used to discharge the gas outlet according to product specifications. - Leaks and spills: Possible leakage and spill intervention procedures and response equipment should be available. - Water-based organic peroxides after freezing, breaking or grinding, dissolving by heating: It should be self-releasing, should not be exposed to thermal or mechanical influences. - Electrical arc or mechanical spark: All electrical and mechanical ignition sources must be removed.
