What is meant by peroxide

II. Definitions

§ 2

(1) Organic peroxides are derivatives of hydrogen peroxide in which one or both hydrogen atoms have been replaced by organic groups. Organic peroxides in the sense of this accident prevention regulation are both the pure substances and their preparations with other substances, insofar as they contain organic peroxides in such an amount that their danger is determined by the peroxides they contain. THERE

(2) Active oxygen is the oxygen of the peroxide group that can be split off and is available for oxidation reactions (1 oxygen atom per peroxide group). THERE

(3) In the sense of this accident prevention regulation are / is

1.Bottling conveying from stationary or mobile vessels to other vessels or containers,
2.Off the storage required for the continuation of the work for up to 24 hours or until the following working day. If this working day is a Saturday, the period ends at the end of the next working day. This can be done as a finished or intermediate product in a packaging determined by the company or in a shipping package, so that it can either be kept ready, shipped or stored,
3.Store the generic term for parking, ready and storage,
4.Processing of organic peroxides changing their nature or content by means of physical methods, THERE
5.Stand by short-term temporary storage for a maximum of 24 hours or until the following working day also in shipping packages in the amount required for the progress of the work at or near workplaces in order to be filled, processed, conveyed, transported, processed or destroyed, THERE
6.Business buildings or facilities Buildings or systems with permanent workplaces, regardless of whether they handle organic peroxides or not,
7.Throughput the quotient of the amount of the substance used in kg and the measured burning time in min, determined in a fire test for the purpose of assignment to hazard groups, THERE
8.Promote and forward in-house transport with stationary equipment, THERE
9.Produce organic peroxides the intended production of organic substances as end or intermediate products containing the peroxide group by chemical reactions; Intermediate products within the meaning of sentence 1 are not present if organic peroxides only arise as intermediates in the process flow in harmless concentrations and cannot be isolated, THERE
10.warehouse a building, room, fixed container or outdoor area intended to store organic peroxides, THERE
11.storage area the area designated for the storage of organic peroxides,
12.Warehouse building Structural facilities firmly connected to the ground, which offer sufficient protection of the stored goods against the effects of the weather and are used exclusively for storage and the work necessary for the operation of the warehouse,
13. To store the storage of organic peroxides for later use as well as for delivery to others. Delivery to others includes the provision for transport if this does not take place within 24 hours or on the following working day. If this working day is a Saturday, the period ends at the end of the next working day,
14.Storage rooms Rooms in which organic peroxides may be stored together with other substances; these rooms can be in storage buildings or in other buildings, THERE
15.Safety distances the distances to be maintained within an establishment, measured as the shortest distance between the facing boundaries,
16.Transport in-house conveyance that is not conveyance or forwarding, THERE
17.Handling the manufacture or use,
18.Use Filling, storing, processing, holding ready, conveying, forwarding, storing, transporting, processing or destroying organic peroxides,
19.To process the use of organic peroxides for the production or treatment of other substances if the organic peroxides are chemically converted in the process,
20.Destroy the conversion into other substances by means of suitable measures for the purpose of disposal, THERE
21.Direction of action the reference direction considered when dimensioning the safety distances from buildings and outdoor facilities in which organic peroxides are handled, to other buildings and outdoor facilities,
22.Store together the joint storage of different organic peroxides with one another or with other substances or materials within the same storage area or in different, but inadequately separated storage areas or storage areas for other materials. THERE

DA to § 2 Paragraph 1:

For the assignment of organic peroxides to hazard groups, see Section 3 (2).

With regard to preparations of organic peroxides with an organic peroxide content of less than 10%, see Section 33, Paragraphs 2 and 3.

DA to § 2 Paragraph 2:

The mass fraction of active oxygen in percent (AO-%) can be calculated according to the formula

16 x number of peroxide groups in the molecule AO-% = --------------------------------------- ------ X 100 molar mass of the compound

to calculate.

DA to Section 2 Paragraph 3 No. 4:

This can be achieved, for example, by drying, mixing, dissolving, crushing, melting.

DA to Section 2 Paragraph 3 No. 5:

This means that the temporary storage takes place in the sense of being kept ready for a few hours with the aim of immediately and immediately supplying organic peroxides for filling, processing, transporting, transporting, processing or destroying. As a rule, keeping available includes the quantities that are in the places provided for the types of handling mentioned and are not yet in the work process.

DA to Section 2 Paragraph 3 No. 7:

For the hazard group assignment, the combustion behavior of an organic peroxide in its packaging, based on an amount of 10,000 kg, is determined by the "corrected material throughput" Ak (kg / min). This takes into account the degree of completeness and uniformity of the burn as well as the heat radiation capacity (emissivity) of the flames. See Explosives Storage Guideline SprengLR 011 "Guidelines for Assigning Other Explosive Substances to Storage Groups".

DA to Section 2 Paragraph 3 No. 8:

Such stationary devices are e.g. pumps, pipelines, continuous conveyors.

DA to Section 2 Paragraph 3 No. 9:

Plants in which organic peroxides are only formed intermediately in harmless concentrations and which cannot be isolated are not subject to this accident prevention regulation because the danger emanating from such plants is not determined by the organic peroxide.

The harmlessness of the concentration of an organic peroxide formed as an intermediate can depend to a decisive extent on the reaction conditions chosen.

DA to Section 2 Paragraph 3 No. 10:

Fixed containers are e.g. silos, storage tanks.

DA to Section 2 Paragraph 3 No. 14:

See also § 26.

DA to Section 2 Paragraph 3 No. 16:

Transporting is, for example, transporting with vehicles or industrial trucks.

DA to Section 2 Paragraph 3 No. 20:

Suitable measures are, for example, burning or chemical conversion through reduction, oxidation or catalytic decomposition.

DA to Section 2 Paragraph 3 No. 22:

There is no storage together if the various storage areas are separated by structural measures in accordance with Section 5 (2) or by spacing according to the minimum spacing between storage and storage of the respective risk group in accordance with Section 4.1 of Annex 1 to these accident prevention regulations.
