It is specified in numbers of regulations, laws and technical. Basically, the following essential requirements have to be met when clustering hazardous substances: - Hazardous substances may only be stored together if this does not result in a risk increase - Substances of the same LGK or substances of different LGKs for which separate storage is not required may not be combined as well if this can lead to a substantial risk increase. This is given when the substances, e.g. 1. require different extinguishing agents, 2. require different temperature conditions, 3. react with the formation of flammable or toxic gases or 4. react with formation of a fire. - Separated storage is provided when different materials are separated from one another in the same storage section by a sufficient distance or by barriers (e.g. by means of walls, cabinets made from non-combustible material, products of non-combustible substances of LGK 12 or 13) or by storage in separate collecting rooms. - Separate storage is provided when substances are stored in different storage sections with a fire resistance duration or capability of at least 90 minutes. As you can see below you will be able to define quickly and clearly the permissibility of clustering concerning the different substances by means of a simplified list. Please have a look at the TRGS 510 for further information on „constrained clustering“. The concept is based on assigning respective substances to so called storage classes (LGK) apparent from related safety data sheet or is to be determined as per TRGS 510, annex 2. In the overview for each LKG a statement is given, whether clustering with each of the remaining LKG is permitted generally, a prohibition of clustering exists (seperate storage is requested!) or a restriction is to be observed (e.g. seperate storage is requested when storing in the same storage section).
