3 Introduction According to the German Responsible Care programme, which is part of the chemical industry`s international Responsible Care initiative, the strategy of mixed storage of chemicals in cooperation with customers, dealers and users aims to make a significant contribution to storage safety. This strategy includes rules for the mixed storage of chemicals. It is based on German laws, regulations and technical rules dealing with the storage of chemicals. Recommendations, publications and discussion papers from associations and companies are taken into account. 15 Storage classes 5.1 A, 5.1 B and 5.1 C: Oxidizing substances Oxidizing products which, because of their oxidation potential, may increase the burning rate of combustible substances or ignite combustible substances in contact with them. This storage class includes products classified in FIT Groups 1 to 3. 5.1 A: Products listed in TRGS Group 1 B: Products listed in TRGS Groups 2 and 3 C: Products listed in TRGS 515 Groups A to C. 5 Storage classes The storage classes have been established on the basis of the dangerous goods classes of the Transport Ordinance The hazard characteristics of the Risk Ordinance Other regulations The allocation of product storage on the basis of available data. Source of First of all dangerous goods marking Transport regulations Information in the safety data sheet The shelf life and shelf life of VCI packaging products may vary slightly depending on the manufacturer. The typical shelf life of polypackaging is 2 to 3 years, followed by a shelf life of up to five years. VCI kraft paper packaging has a shorter shelf life and can usually be stored for 1 year and then protected for up to a year.

VCI packaging products offer the best protection for the longest duration when stored properly. Contact our VCI packaging experts to set up an ideal storage and supply solution. 6 storage classes Information provided by the supplier on non-hazardous products Real-world results can be used If the supplier of a product does not provide information on the classification of the storage class, this can be done according to the flowchart. Do you currently use volatile corrosion inhibitor (VCI) packaging to protect metals from corrosion? Wondering how best to store VCI packaging such as polyfilm rolls and VCI bellows bags before use? Because VCI products are designed to diffuse their protective chemicals in open spaces, the key to maintaining their effectiveness is to keep them firmly in airtight, airtight packaging. The following five tips are the manufacturer`s recommendations during storage, as well as for extended downtime and interim use. 1 VCI Guidelines for Mixed Storage of Chemicals F.Shabani M.Sc. Department of Physical Chemistry Razi Vaccine Serum Research Institute 1389/9/3 Corrugated cardboard is made of paper. A first step in the papermaking method is to treat the raw wood with chemicals to break it down into a fibrous pulp – this is an acidic process and it can leave an acid residue on the cardboard.

A characteristic of corrugated cardboard is that it is absorbent and when it absorbs water/moisture, it causes the acid residue to activate. When metal or metal parts are placed directly on or near the wet corrugated sheet during storage or transportation, moisture and acidity induce corrosion on the surface of the metal parts. The placement of ARMOR VCI products between the metal and the corrugated board prevents corrosion and keeps the metals clean and free of rust. VCI and desiccant protect metal parts in very different ways with very different chemistry. One way to explain their differences is to use a give-and-take analogy. ARM`s proprietary VCI nanotechnology “gives” or emits a vapour that prevents corrosion by forming a protective layer on the metal surface. Desiccants are desiccants that “absorb” or adsorb moisture from the packaging environment, which is one of the main causes of corrosion. Depending on the application and specifics of the storage or shipping environment, one method may perform better than the other, where VCI and desiccant are often used together to provide best-in-class protection of metal parts in highly demanding packaging environments. 20 storage classes 7: Radioactive material Classification according to transport law RID/ADR: 7 storage classes 8A and 8B: corrosive substances This storage class includes products marked with the hazard symbol C R sentence 34 or 3 Classification according to transport law RID/ADR:8 The storage class is divided into fuel and non-combustible ARMOR combines its proprietary VCI nanotechnology with materials such as paper kraft, Polyfilm, chipboard or foam padding for the production of clean and dry packaging materials with the added benefit of rust protection.

We pour VCI into packaging materials and turn them into rolls, sheets, VCI bags or pipes. When metal parts are wrapped or covered with VCI plates or enclosed in VCI bags or pipes and placed in a closed container for storage or shipping, the VCI vapours dissolve, forming a protective layer on the metal surface that repels rust. 17 Storage classes 6.1 A, 6.1 B: Toxic substances Storage classes include products bearing hazard marks T+ and T. Very toxic and toxic substances 6.1 A: Flammable toxic substance Liquids: Water miscible Flammable with a flash point > 55 ºC Water-miscible fuel with a flash point >100 ºC Aqueous preparations containing flammable toxic substances Solids: with combustion figures 2, 3, 4, 5 8 The description of the storage classes is based on: Designation in transport Dangerous Goods Legislation Technical Regulations General product characteristics Storage class 1: Explosives For classification 4, the criteria for the explosive are low and the Class 1 RIM/ADR transport duty is used For storage safety reasons, all products to be stored must be assigned to storage classes according to their product-specific hazard. characteristic. Hazardous property Explosive Extremely flammable, highly flammable, flammable Oxidizing. Very toxic or toxic Corrosive 26 Rule for mixed storage of products The storage of products that must be stored separately in safety cabinets in accordance with DIN 12925, Part 1 in the same room generally meets the requirements for separate storage (see TRGS 514 NO) Separate storage Storage means storage in the same storage area, if products pass through gaps or barriers (e.g. walls, products made of non-combustible materials of storage class 12 or 13) or into a cabinet made of non-combustible material) 2 Content 1) Introduction 2) Storage class 3) Mixed storage rule This article is intended to provide a basic introduction to vapour corrosion inhibitors to be used in corrosion prevention for aboveground storage and to cover the state of this technology. Metal parts are produced in different sizes, shapes and metal compositions. In addition, they are exposed to a variety of environmental conditions and vary greatly in the duration of protection they need.

VCI is not one size fits all formulations or products and for this reason, ARMOR offers a wide range of VCI products to keep the metal free of rust. ARMOR WRAP® VCI paper, ARMOR POLY® VCI film, chipboard, foam padding, emitters and liquids are designed to protect metal from corrosion during processing, storage or shipping/transportation.
