Definition of a Class 5.2 A class 5.2 product is defined as Organic substances which contain the bivalent -0-0- structure and may be considered derivatives of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic radicals. Organic peroxides are thermally unstable substances, which may undergo exothermic self-accelerating decomposition. The maximum temperature under which the self accelerating decomposition does not occur is called SADT (Self Accelerating Decomposition Temperature). It is specific of each peroxide formulation and of the packaging size and shape. In addition, they may have one or more of the following properties: (i) be liable to explosive decomposition; (ii) burn rapidly; (iii) be sensitive to impact or friction; (iv) react dangerously with other substances; (v) cause damage to the eyes. (Note 1) Note (1) Source the Australian Dangerous Goods Code 7th Edition page 95

Properties of Class 5.2 Organic peroxides are liable to exothermic decomposition at normal or elevated temperatures. The decomposition can be initiated by heat, contact with impurities (e.g. acids, heavy-metal compounds, and amines), friction or impact. The rate of decomposition increases with temperature and varies with the organic peroxide formulation. Decomposition may result in the evolution of harmful, or flammable, gases or vapors. For certain organic peroxides the temperature must be controlled during transport. Some organic peroxides may decompose explosively, particularly if confined. This characteristic may be modified by the addition of diluents or by the use of appropriate packaging. Many organic peroxides burn vigorously.

Class 5.2 Label for Organic Peroxides The new alternative labels for Division 5.2 (model No. 5.2B) should be phased in where possible during the currency of the Australian Dangerous Goods Code 7th Edition. Use of the No 5.2a Label will not be permissible in Australia or internationally from 1st January 2011. (Note 1). Note (1) Source the Australian Dangerous Goods Code 7th Edition page 426

Classification of Class 5.2 Products Organic peroxides are classified into seven types according to the degree of danger they present. The types of organic peroxide range from type A, which may not be accepted for transport in the packaging in which it is tested, to type G, which is not subject to the provisions for organic peroxides of Division 5.2. The classification of types B to F is directly related to the maximum quantity allowed in one packaging. (Note 1) Note (1) Source the Australian Dangerous Goods Code 7th Edition page 98

Temperature Control Requirements The following organic peroxides must be subjected to temperature control during transport: (a) Organic peroxides type B and C with an SADT ≤ 50 °C; and (b) Organic peroxides type D showing a medium effect when heated under confinement with an SADT ≤ 50 °C or showing a low or no effect when heated under confinement with an SADT ≤ 45 °C; and (c) Organic peroxides types E and F with an SADT ≤ 45 °C.

Storage All class 5.2 product needs to be Placed in stores ASAP after unloading Picked immediately prior to loading Stores kept closed when not transferring Suitable controlled temperature transport Peroxides not to be left outside stores Control spills as per Site’s Chemical Spill Procedure Do immediately notify your Supervisor/ Manager of any incident or issues involving class 5.2 products. Do immediately notify your Supervisor/ Manager if you notice that class 5.2 packaging has swollen or bloated. Customer is to be contacted and notified to organise pressure release. Cap needs to be opened to allow pressure release. This is never to be conducted alone. Do check products for damage and incorrect or non compliant DG labelling. Do leave distance between product and storage walls/floor/ceiling to allow heat escape. Air space between pallets improves air circulation. Recommendation for reefer container storage is 20 cm away from door and 10cm between pallets Don’t store liquids above solids Don’t allow contact with dust or chemical. Dust can contain acids or other materials that can contaminate and explode. Don’t allow sources of ignition (turn on FLT isolation switch when entering any 5.2 storage area)

Management of Leaks General It is essential that due attention be paid to leaks and spills of organic peroxides, since these are a potential source of injury to persons, damage to property, and pollution to the environment. Every Endeavour shall be made to prevent leaks or spills, and to control them if they do occur; clean up action shall be initiated immediately. Leaked or spilled organic peroxides shall be stored and disposed of in accordance regulatory authorities NOTE: Entry of personnel into the affected area should always be under supervision. Clean-up materials and equipment Suitable non-combustible, inert absorbents, e g. clean sand or vermiculite, shall always be available in every store in which liquid organic peroxides are stored or handled. These absorbents should be clearly identified. Water shall be used for damping leaks and spills of solid organic peroxides, and a suitable broom or brush shall be available for sweeping them up subsequently. Clean, sealable, vented waste bins, made of material compatible with the organic peroxides being dealt with, shall be available for the containment of absorbed spills. It is advisable that such waste bins be filled to not more than two-thirds of their capacity.

Management of Leaks Continued Clean-up procedures The following procedures, as appropriate, shall be adopted in the cleaning up of leaks and spills of organic peroxides: (a) Leaked or spilled liquid shall be soaked up with the non-combustible absorbent, collected and stored in the waste bins. (b) Leaked and spilled solid shall be damped with water, swept up, collected and stored in the waste bins. (c) The waste bins shall be suitably labeled and kept in a safe location, away from the storage and handling areas and from sources of ignition, heat, other dangerous goods and incompatible substances, until the waste can be disposed of. If disposal is likely to be delayed, the waste should be soaked with water. (d) Finally, the floor or other contaminated surfaces shall be thoroughly cleaned of any residual organic peroxide. Contaminated materials resulting from this process shall also be stored in waste bins, and dealt with as in Item (c).

Personal Habits Personal habits and hygiene practices have an important bearing on health and safety. The following rules shall be followed by all persons whose work involves the handling of organic peroxides: (a) Do not introduce, keep, prepare or consume any food or drink, or use tobacco. In any place where dangerous goods are stored or handled. (b) Always wash your hands before eating, drinking or smoking, and after work. (c) Immediately attend to injuries caused by contact, or suspected contact, with organic peroxides or other dangerous goods.

First Aid The following first aid procedures shall be adopted for the treatment of accidents relating to the handling of organic peroxides: (a) Eyes If organic peroxide enters the eyes, thorough irrigation with water shall be commenced simultaneously with the seeking of medical attention. The irrigation shall be continued for at least 15 minutes. (b) Skin If splashes of organic peroxide occur on the skin, contaminated clothing shall be removed and the skin shall be washed immediately with plenty of water; solvents shall not be used. Oily solutions or ointments should not be used as first aid measures. If a skin burn develops, medical attention shall be obtained. (c) Inhalation Since any significant inhalation of organic peroxide dust, vapor or fumes will cause irritation to the upper respiratory tract, if such exposure occurs the patient shall be removed to fresh air and be allowed to rest while medical attention is being obtained. The patient shall be kept warm. (d) Ingestion If swallowing of organic peroxide occurs, medical attention shall be sought immediately, and the Poisons Information Centre shall be contacted for advice. Except where benzoyl peroxide has been swallowed, vomiting should not be induced. If the patient is conscious, the mouth shall be washed out with water, and the patient be made to drink a glass of water. If benzoyl peroxide has been swallowed and the patient is more than 15 minutes from a hospital vomiting should be induced, preferably using Ipeac Syrup APF.
