Any rack outside of these parameters typically requires a qualified design professional&#8217;s review.<\/p>\n<p>Even when the quick-ship rack is appropriate for a warehouse, there may be a need for expert input if there are special circumstances \u2013 for example, if rack installation occurs on a sloping floor.<\/p>\n<p>Also, it makes sense to seek guidance whenever it is necessary to coordinate with integrators or safety and trade professionals under deadline.\u00a0 Troubles often occur when someone decides that it is quicker and cheaper to buy quick-ship racking when the application really calls for an engineered system. When optimal storage, material flow, safety and compliance is required in a warehouse, proactive managers will get the help they need upfront to avoid costly surprises, delays, or retrofits.<\/p>\n<p>&nbsp;<\/p>\n<h3>Q: \u00a0What are some of the key <strong>seismic facts that warehouse managers need to be aware of today?<\/strong><\/h3>\n<p><img decoding=\"async\" style=\"float: right; width: 100%; max-width: 450px; height: auto; margin-left: 10px; margin-top: 10px;\" src=\"https:\/\/images.cisco-eagle.com\/blog\/wp-content\/uploads\/2019\/07\/National-Seismic-Hazard-Zones.jpg\" alt=\"National Seismic Hazard Zones\" \/> A:\u00a0 While all U.S. states have some potential for earthquakes, 42 of the 50 states have a reasonable chance of experiencing damaging ground shaking from an earthquake in 50 years, which is generally considered the lifetime of a building. Because storage racks are considered building-like structures according to the International Building Code, and are represented as such in the Rack Manufacturer\u2019s Institute (RMI) Standard, racks need to be designed to the local seismic requirements just like a building.<\/p>\n<p>Since the RMI is the recognized U.S. specification for the design, testing and utilization of industrial steel storage racks, responsible warehouse managers will want their racks to meet this recognized standard for seismic design. RMI created the R-Mark Certification Program as a way for storage rack users to clearly identify those rack manufacturers whose components and design are in accordance with the RMI Specifications. \u00a0<a href=\"https:\/\/www.cisco-eagle.com\/category\/7039\/steel-king-seismic-racks\">Steel King<\/a> is one of a select number of rack manufacturers that holds an active R-Mark License and is a licensed fabricator in Los Angeles County, which has some of the strictest seismic codes in the nation.<\/p>\n<p>&nbsp;<\/p>\n<h3>Q:\u00a0 Why do warehouse managers need input from a design professional today to stay seismically compliant?<\/h3>\n<p>A:\u00a0 Seismic zone designations are changing.\u00a0 The United States Geological Survey (USGS) uses ground acceleration values, referred to as Seismic Design Categories (SDC) from A to F. With seismic requirements increasing in many parts of the country and with a better understanding of structural performance during an earthquake event, these standards will continue to evolve, placing more demand on the rack design.<\/p>\n<p>Seismic separation is another requirement for racks placed within an existing warehouse.\u00a0 This means the rack needs to be a certain distance away from the building columns so they will not collide during an earthquake.\u00a0 In high seismic regions, special inspection is typically required.\u00a0 An independent inspector will watch the installation and verify proper bolt tightening, especially the anchor bolt, along with checking for rack damage and missing or poor welds.<\/p>\n<p>&nbsp;<\/p>\n<h3>Q:\u00a0 Do outdoor racking or rack-supported structures have any specific environmental requirements?<\/h3>\n<p>A:\u00a0 Outdoor racking, as well as rack-supported structures, must be designed to account for wind, rain, and snow loads. In hurricane-prone regions, for example, outdoor rack and rack-supported structures must be designed to withstand the force of high-speed winds in addition to standard product and dead loads. When heavy snowfall is prevalent, the outdoor rack and rack-supported structures must accommodate the accumulated weight of both snow and snowdrifts, which occur when wind pushes snow up against taller structures or towers.<\/p>\n<p>In all such unusual environmental conditions, of course, it is essential to consult with a professional about incorporating necessary safety factors into the rack design.<\/p>\n<p>&nbsp;<\/p>\n<h3>Q:\u00a0 What do warehouse managers need to know to keep <strong>engineered systems including pick modules and AS\/RS structures safe and compliant?<\/strong><\/h3>\n<p><img decoding=\"async\" style=\"float: right; width: 100%; max-width: 200px; height: auto; margin-left: 10px; margin-top: 10px;\" src=\"https:\/\/images.cisco-eagle.com\/blog\/wp-content\/uploads\/2019\/07\/AKecke.jpg\" alt=\"engineer Arlin Keck from Steel King Industries\" \/> A:\u00a0 By definition, an engineered system is any non-standard storage rack that requires special design considerations.\u00a0 This can include a variety of <a href=\"https:\/\/www.cisco-eagle.com\/category\/772\/racks\">rack types<\/a> and safety equipment that is semi-customized or actually custom-designed specifically to the warehouse application.<\/p>\n<p>In terms of safety, racking must be designed for any unusual stresses, loads, or functions placed upon it.\u00a0 It must also meet applicable fire codes and insurance requirements.\u00a0 For instance, racking loaded with flammable products would require certain accommodations to assure adequate fire detection, containment, and suppression. Some of the most highly engineered systems actually involve <a href=\"https:\/\/www.cisco-eagle.com\/vector\/632\/pick-modules\">pick modules<\/a>, elevated platforms, and <a href=\"https:\/\/www.cisco-eagle.com\/category\/680\/mezzanines-platforms\">work platforms<\/a>.\u00a0 In such engineered systems, a number of key factors must also be addressed to ensure safety, compliance, and permitting.<\/p>\n<p>To comply with the fire code, you need to address the means-of-egress (the path to exit a building), travel distance, and head clearance\/exit width.\u00a0 This is based on the number of people who have to evacuate the racking system. In order to provide safe access and <a href=\"https:\/\/www.cisco-eagle.com\/category\/9303\/fall-protection\">fall protection<\/a>, the placement of suitable stairs, ladders and guarding should also be implemented throughout the engineered system. Because dropping off pallets or equipment at elevated levels may be needed as well in such engineered systems, providing for safe drop zones, through an opening in the side railing to allow easy receipt, should be properly planned too.<\/p>\n<p>&nbsp;<\/p>\n<h3>Q:\u00a0 The serviceability of engineered rack like AS\/RS systems is essential to maintain warehouse performance and longevity. How can warehouse managers optimize this?<\/h3>\n<p>A:\u00a0 Ensuring that the engineered system functions as designed and that the employees working on an engineered rack structure feel comfortable is another consideration. Generally, this is referred to as serviceability.\u00a0 The term refers to how certain structural elements like elevated walkways must provide the desired support and stiffness for walking or cart use without unacceptable flex (bounce) or sway. While such engineered systems require substantial input from a design professional, <a href=\"https:\/\/www.cisco-eagle.com\/vector\/172\/asrs-systems\">AS\/RS structures<\/a> \u2013 which can be over 100 feet tall and bear loads greater than 100,000 lbs. per storage bay \u2013 require even more planning and integration.<\/p>\n<p>In today\u2019s warehouse environment, AS\/RS systems are increasingly popular in big box store distribution centers and large freezer companies for their ability to provide very high volume, high turnaround storage with minimal labor. With AS\/RS systems, there is a lot more interfacing between the equipment and the racking.\u00a0 Because these systems use automated cranes and usually map each location on a coordinate plane via computer, the tolerances are a lot tighter. Since the machines stop at precise locations, each opening has to be at the exact location. So, the racking must be very stiff and the rack must be straight and plumb.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Buying standard storage racks for quick-shipment from a manufacturer used to be the norm.
