Only to tell how complex is would be to make a practical magical matrix, take a look below copied from the ATEX guide:
EQUIPMENT SPECIFICALLY EXCLUDED FROM DIRECTIVE 94/9/EC These exclusions are based on Article 1.4, laid down in directive 94/9/EC: 1. medical devices intended for use in a medical environment; 2. equipment and protective systems where the explosion hazard results exclusively from the presence of explosive substances or unstable chemical substances; 3. equipment intended for use in domestic and non-commercial environments where potentially explosive atmospheres may only rarely be created, solely as a result of the accidental leakage of fuel gas; 4. personal protective equipment covered by directive 89/686/EEC 39 . There are occasions where personal protective equipment with its own potential sources of ignition is intended for use in potentially explosive atmospheres. This type of personal protective equipment should follow the procedures laid down in directive 94/9/EC to provide the necessary level of explosion safety (see as well chapter 6); 5. seagoing vessels and mobile offshore units together with equipment on board such vessels or units, because they are already covered by the IMO Convention. However, fixed offshore units together with equipment on board, and units and vessels, which are not considered to be seagoing (i.e. below 500 tonnes, not intended for high sea but intended for internal navigation on river, ship canal, lakes), are in the scope of directive 94/9/EC; 6. means of transport i.e. vehicles and their trailers intended solely for transporting passengers by air, road, rail or water networks, as well as means of transport in so far as such means are designed for transporting goods by air, by public road or rail networks or by water. Vehicles intended for use in a potentially explosive atmosphere shall not be excluded; 7. equipment covered by Article 296 (1)(b) of the EC Treaty, i.e. designed and manufactured specifically for use by the armed forces or in the maintenance of law and order. Dual-purpose equipment is not excluded. Yes, is possible to make a magical matrix, but I think it would take much much time to generate it.
