Modula ANTI-SEISMIC SOLUTIONS The seismic What anti-seismic means resistant vertical for a Modula storage storage system system Following the earthquake in Emilia (Italy) in 2012, Modula got to work on a solution that should be able to withstand earthquakes and thus guarantee: GOODS PERSONNEL PROTECTION SAFETY SYSTEM QUICK RESUMPTION INTEGRITY OF ACTIVITIES It took 4 years of in-depth studies, calculations and computer simulations to develop the revolutionary seismic isolation system we know today. These calculations and simulations were all validated by tests carried out at the Eucentre in Pavia, the main European center for training and research in earthquake engineering. 2

The concept Modula’s approach was to combine anti-seismic and seismic isolation solutions. The first concern the reinforcement of the storage system’s structure, whilethe second relate to its isolation from the energy produced by the accelerations generated by earthquakes. Modula chose to avoid excessively stiff structures, so that the storage system does not weigh too much,and to focus the analysis on the movement of earthquakes as well as the effects of the accelerations involved, especially of the horizontal component of peak ground acceleration (PGA). The seismic isolation system comes into play only in the event of earthquakes and it is important to highlight that in non-seismic situations the device does not affect the operation of the storage system in any way.

Modula ANTI-SEISMIC SOLUTIONS Regulatory A quick look at the framework laws in force In Italy, seismic risk and the consequent regulations were based on a seismic classification of the area until 2018. For example, Italy was divided into 4 seismic zones and specific regulations were applied according to that classification. Today the situation has changed, although one may still hear about this classification. Since 2018 seismic zones are only considered together with the parameters to be used in civil and industrial design: PLACE OF CONFIGURATION INSTALLATION OF THE MACHINE INTENDED USE OF THE BUILDING SOIL TYPE The Italian Ministry of Labor approves structures exclusively if designed according to the following hierarchy of technical standards (circular letter no. 21346 of 13/09/1995): 1) Binding EU legislation 2) Binding national laws and technical standards 3) Higher-ranking standards issued at the European level, such as EN standards 4) Standards issued at national level, such as the UNI standards 5) Voluntary “good practice” standards issued by European or Italian bodies and/or manufacturers’ associations, if any. We therefore speak of structural design in compliance with good practice standards. “Manufacturers must demonstrate the load bearing capacity of their products, applying the most appropriate methods, including specific experimental tests, to verify and/or validate their anti-seismic behavior.” 4

The standards applied by Modula Modula solutions are fully compliant with the regulatory framework, in particular: REF. 1 REF. 2 NTC (Italian Technical Construction Standards) Circular no. 617 of 02/02/2009 updated in february 2018 These standards relate to seismic isolation as a means for reducing the horizontal seismic response of a structure. According to these standards, anti-seismic systems must: • Be able to support vertical loads • Have low horizontal stiffness • Ensure energy dissipation • Be able to re-center the system • Be sufficiently stable and rigid laterally. System lifespan Nominal lifespan of a system: this is the number of years a routinely maintained structure should be able to be safely and efficiently used for its intended purpose. The actual lifespan of a system is calculated as follows: L X Cu = Nominal lifespan x Coefficient of use OUR SOLUTION IS CERTIFIED BY MODULA FOR A LIFESPAN OF 35 YEARS 5

Modula ANTI-SEISMIC SOLUTIONS Solutions Seismic isolation IS 2 and IS 3 system The IS 2 and IS 3 solutions are related to the concept of seismic isolation. The principle is to minimize the forces transmitted from the ground to the storage system structure. The isolation system dissipates the energy produced by the accelerations resulting from the seismic event, transferring just a percentage of this energy to the structure: thanks to the reduced friction between the progressive resistance feet and the sliding plates, the system tends to be displaced laterally only to a limited extent. By considerably reducing the accelerations transmitted to the storage system, and with them the stresses exerted on the load-bearing elements of the racking, the risk of the trays being displaced and falling is eliminated. Falling trays would not only cause damage to the goods stored in the system but may also damage the structure itself and cause objects to be dropped, thereby jeopardizing the safety of personnel. The elimination of the risk of the trays falling is certainly the most important advantage of a system equipped with seismic isolation technology. The seismic isolation system consists of: • A controlled and progressive friction contact system (IS2 and IS3) comprised of a pad placed between the feet and the steel plates that serve as support bases. • A damping system with non-linear progressive springs (IS3) to limit horizontal movements while remaining within the acceleration range the structure can withstand. • An electronic emergency stop device controlled by an accelerometer, available as an option for all solutions. In non-seismic situations the seismic isolation system does not affect the regular operation of the storage system. Its installation does not require any special modifications: the sliding plates and the anti-tip system must be anchored to the floor, while all the other elements are an integral part of the storage system structure. 8

Modula ANTI-SEISMIC SOLUTIONS Software Software and options The anti-seismic system also includes specific management software. This is not Modula’s WMS but a function of the Modula OS. In the storage systems with seismic isolation heavier goods must be placed at the bottom to lower the center of gravity. This approach is an alternative to the usually adopted cycle based on ABC analysis, where the most frequently handled goods are placed closer to the bay Options One of the significant aspects of the Modula anti-seismic solutions is the short time needed to resume operation following an earthquake. This is possible thanks to an optional consisting of: • An accelerometer that records seismic shocks • A system that monitors the proper position of each tray. The accelerometer detects all seismic shocks and records horizontal acceleration even when the machine is off; if the machine is actually moving, the operation of the storage system is immediately and safely interrupted. At the end of the earthquake, when the machine is switched back on, an automatic procedure checks the correct position of each tray by means of special internal photocells. If the trays are in the correct position (on the shelves), the machine can be restarted and resume normal operation. Otherwise, the intervention of Modula’s technicians is required. This optional function can be installed in all solutions. 13
