Storage System Options And Technical Considerations

APRIL 4, 2003 -- REVISED OCTOBER 1, 2008

This document discusses options pertaining to the installation of bin storage in health care facilities. Note that there are other storage methods (including what you may already possess) you may use but here we specifically examine that of bins.

There are two primary methods to review:

1. Various methods for mounting wall mounted louvers directly to the wall.

2. Using a free-standing partition panel system with attached louvers.

Note: This document is intended to be informational in nature. It is written to provide installation information and options for facilities managers, structural engineers and architects. It is the responsibility of the hospital’s "Engineer of Record", structural engineer or architect to determine the installation methods best suited to the hospital’s need to comply with local and state building and fire codes. That person is also responsible for performing any necessary reviews of the facility’s structure, performing any structural analysis and specifying any reinforcement of walls that may be required. The information contained in this document is presented as suggestions only. Its efficacy must be evaluated on a case-by-case basis.

OVERVIEW

When bins are utilized as the storage system in conjunction with the PAR Excellence System, the basic configuration consists of various sized bins attached to louvered panels. These louvered panels are mounted vertically on a surface and arranged in a matrix to create the storage space required. The louvers may be hung on the wall using screws driven into the underlying wall studs or they may be attached to a free-standing Herman-Miller partition panel. In both cases, the louvers support an arrangement of movable bins which are hung from these louvers.

The mounting system for these mounting plates is defined below. The louvers are supplied in two sizes – 19” H x 36” W or 19” H x 18” W. The louvers are typically 36” wide and are arranged three high (57” total). The bottom of the louver stack is typically located 16”-18” above the floor. This spacing locates the top bin of a three-louver stack at about 73”, which is within reach form most people. There is also ample room below the lower bin for cleaning, etc.

The bins are typically arranged with the larger, heavier items located at the bottom of the stack and the smaller, lighter items located at the top. JCAHO standards mandate that liquids, such as IV solutions, not be stored above other items. Therefore, IV solutions are typically placed in large bins at the bottom of the stack while lighter items are in smaller bins at the top.

TYPICAL PAR LOCATION STORAGE SYSTEM INSTALLATION. This stack is representative of a heavily loaded section (approximately 25 pounds per square foot (PSF), with a large number of solutions stored in large bins. Smaller, lighter items (less than 20 pounds per square foot) are stored above. This could be considered a worst-case configuration for weight loading.

LOUVER MOUNTING OPTIONS

The louvers can be mounted either to a wall or to a Herman-Miller partition. Both these options require that the mounting surface be able to safely carry the weight (static load) plus dynamic loads of the louvers, installed bins and their contents. These requirements are typically specified by local and state building codes.

WALL MOUNT STORAGE

Two basic wall mounting configurations are recommended based on the wall’s construction. All mounting and support systems must comply with local and state building codes where applicable.

Masonry Wall Mounting To mount to masonry walls, the use of embedded wall anchors is recommended. A ¼” minimum diameter wall anchor should be installed at each of the 12 louver attachment points on each panel.

Stud Supported Wall Mounting There are several options for mounting louvers to a stud-supported wall. The variations are based on the strength of the wall and the need for additional reinforcement.

Light Duty Wall Mounting For light duty applications, static loads of less than 10 pounds per square foot, toggle bolts or expansion anchors may be used on drywall-clad walls

Standard Duty Externally Reinforced Wall Mounting For standard duty applications, static loads up to 25 pounds per square foot, it may be necessary to reinforce the wall. This is the preferred method of louver mounting. A layer of 3/4” BC grade plywood is attached to the wall using flat head screws screwed into the wall studs every 6”. The recommended screw is a Phillips flat head #8 x 2 ½” min length for 3/4” drywall. Longer screws are required for thicker drywall. The surface of the plywood can be painted or can be left unpainted, as the louvers and bins cover most of it. This panel provides a substrate to on which to mount the louver panels and allows the louvers to be mounted anywhere on the plywood substrate.

Louvers are mounted to the plywood panel using #10 x 1 pan head screws and 1” diameter fender washers. Twelve screws should be used to support a 18” x 19” or 36” x 19” louver.

NOTE: Be sure to install all screws in the lowest louver panel in an installation. This louver typically supports the most weight, as the heaviest bins are typically located on the bottom.

FREE STANDING PARTITIONS

Storage bins and louvers can be supported by properly designed and installed partition panels.

The typical installation consists of 18” or 36” panels supported by 18” return panels. The typical length of a partition wall is 6 feet between return panels. The partition panels are typically 80” tall and can support an array of louvers. Using modular partition panels allows the designer to configure the storage area to conform to the specific shape of the room and necessary storage requirements.

TYPICAL PARTITION PANEL INSTALLATION

Panel Support Partition panels require perpendicular supports or returns to be integrated into a wall section at regular intervals. The typical installation is two interconnected 36” panels, 6’ total run length, with a 12” return at each end. The wall may be extended in length as long as these returns are placed every 6’ and on the ends. The wall may also have a 90 degree turn which may be used as a support point. Load-bearing panels must be supported on both ends.

TYPICAL PARTITION INSTALLATION – DRAWING

Panel anchoring Anchoring of the panel to the floor may be required by code. Consult your architect for requirements in your location. California OSHPD requirements require anchoring panels to the floor using embedded anchors. Consult R-0224 for specific details.

Louver and louver attachment The louvered panels used with partition panels are especially designed to support the attached bins and attach directly to the partition panels. The load (weight) of the bins and its contents are carried directly to the partition panel frame by the louver’s locking hooks. Once the louvers are attached to the panel, locking hardware is tightened to lock the louver to the panel.

Bin Anchoring Heavily loaded bins are supported by a high load louver panel. This panel is designed to carry a single row of 6-7/8” tall bins, Akro-Mills 250. The louver is designed to carry 50 pounds per square foot loads.

Mobile Cart Base The mobile cart base is a mobile platform designed to support standard Herman-Miller partition sections. The base has 4-4” diameter swivel casters to allow the base to move laterally during a seismic event. The base is available in two sizes to accommodate a 3’ partition or a 6' partition.

The partitions both have 18” returns. The 6 ft base measures 80” x 28-1/4” and the 3 ft base measures 44” x 28-1/4”. The partitions use the standard louver panels to support the bins. Both the partitions and returns are secured to the base with hardware.
