CONVEYOR POLY‐V BELT FACT SHEET
Selection Considerations
1.9 INCH AND 2.5 INCH ROLLERS
Conveyor systems today offer several drive systems to transmit torque from roller to roller. A relatively new approach was introduced several years back using Poly‐V belts that are stretchy belts assembled on specific hubs attached at each end of a roller. Poly‐V belt driven conveyor rollers offer an alternative to Chain Driven rollers and O‐Ring driven rollers. These rollers can be driven by a motorized drive roller, pancake motor attached to the side of the rail or by using the line shaft method. The power between the drive and the rollers is transferred by the Poly‐V belts. The fact sheet below will cover the 1.9 inch roller as well as the 2.5 inch roller and give the user some design parameters to be used in the selection of the drive and the belt sizes.
Motorized Drive Rollers (MDR) applications with Poly‐V Belts
The typical conveyor application of Motorized Drive Rollers (MDR) involves using an individual motor to power shorter conveyor sections (i.e. conveyor “zone”). An individual zone sensor is also applied one per zone, allowing for some type of logic controller to determine the presence or absence of articles on the conveyor. In turn, the controller only operates the zones as necessary to move the articles being transported. By far, the greatest number of conveyor applications for MDR involve roller conveyor. It is most cost effective to transfer power from the motorized rollers to the idler rollers that form the zone extending the “powered” rollers beyond the individual MDR. Earlier designs used urethane bands (similar to those found in line shaft applications) to serve this purpose. However as product weights and speeds increased, a different type of drive was required to prevent slipping and reduced belt life. The Poly‐V Belt is now being applied to meet these requirements however, there are certain design considerations to keep in mind to insure the correct conveyor operation:
1. Speed
Because of the increased tension of the Poly‐V Belt when compared to
typical O Ring designs, the no‐load and light product load speeds will be slower
than expected. This speed difference will balance out as the article weight
approaches the MDR rated load specification.
Since the MDR is in contact with the article that is being transferred at
regular intervals during the transportation, certain speed differences can be
overcome based on the relationship between product size and zone length.
CEMA Technical Report 2015‐02 Conveyor Poly – V Fact Sheet
2
2. Amperage
The positive drive of the Poly‐V Belt requires additional torque when
compared to O‐Rings. No‐ load amperage can approach rated amperage, even
without product on the conveyor. While the amperage compared to O‐Ring
driven rollers balances out as the load approaches rated capacity, this additional
amp draw should be taken into consideration when sizing the power supplies.
The amounts of applications for the Poly‐V Belt have been increasing recently, and are expected to continue for the future. Usage of the belt has provided additional applications in environments that were difficult or impossible with O‐Rings, such as in the presence of chemicals or low temperatures. Sizing the proper MDR to meet the application requirements is necessary to maximize the potential ROI. 1.9 inch rollers: There is no standard as of this writing for the hub diameter used on the 1.9 inch end hub. Several manufacturers have accepted the dimension of 43 mm which uses the “J” profile found in the ISO standard 9982. These hubs are either injection molded thermoplastics, machined from PA66 material, or metals such as carbon steel, stainless steel or aluminum. Hub inserts with the Poly‐V configurations are manufactured with one or two precision ball bearings depending on the manufacturer. The number of belt ribs required is dependent on the amount of torque that you need to transmit and the speed that is required for your application. Hub manufacturers normally provide 8 to 10 grooves on these hubs. The hubs are normally pressed in or swaged into the roller tubes to secured to the inside diameter of the steel roller. An example of such a hub is dimensioned below:
Design criteria for the parts are based on the belt configuration which is determined from the following information:
1. Length of a zone in the conveyor. 2. Maximum load and footprint of load to be conveyed in a zone.
CEMA Technical Report 2015‐02 Conveyor Poly – V Fact Sheet
3
3. Maximum load per roller. 4. Maximum load in the zone. 5. Speed of the conveyor. 6. Diameter of the roller tube. 7. O.D. of the insert or ring. 8. Special environmental conditions.
From this information the manufacturer of the Poly‐V belts will determine what series belt configuration and how many ribs will be required. When that information is given to the roller manufacturer they will then produce a roller with the appropriate insert or ring. Shaft options include spring loaded, fixed or drilled and tapped and a choice of materials including hex or round configurations. Center distances between rollers can vary so the chart below will give you a quick summary of which belt you must use depending on the center distance selected. This sounds easy, yet you must decide the number of ribs required for the belt and that is based on the load you are transporting and the desired speed. By using the chart below you will be able to select the proper belt for the application.
2.5 inch rollers: Since there are no standards as to the hub diameters for this size hub, several manufacturers have established 60 mm or 63.5 mm for the outside diameter. The construction of these types of hubs is machined steel since these hubs are welded to the 2.5 inch diameter tubing. You

then must decide whether to use a “J” or “K” profile to drive your conveyor. The “J” profile requires a wider belt per the load, which means it will take extra ribs to drive the same load as a narrower “K” profile belt. The benefits of using the “J” are its low profile. By using a “J” profile the belt height when installed is the same overall diameter as the 2.5 inch tube when using the 60 mm hub.

Advantages and considerations of using Poly‐V belt driven rollers versus O‐Ring driven rollers:
More power transferred from roller to roller versus polyurethane O‐Rings
Less belt slippage from Poly‐V belts
One drive powers more slave rollers depending on application
Robotic picking due to more precise stopping and starting
Longer life belts compared to TPU
No maintenance on the Poly‐V belt once it is installed Considerations for Poly‐V belt driven rollers versus Chain driven rollers:
Closer roller centers than sprocket driven rollers
Conveyor can be lower to the ground if motorized rollers are incorporated
No lubrication required with Poly‐V rollers
Robotic picking due to more precise and stopping
Elimination of gear boxes
Noise Safety concern: Poly‐V belts have very little elongation of stretch. Guards or shields should be installed anywhere personnel or property could come in contact with the rollers. Overall: Lower cost of ownership.

FOREWORD
Motor Driven Live Roller (MDR) Conveyors – Conveyors which use individual motors and rollers as a carrying
surface, or utilize a belt as a carrying medium – are used for the controlled movement of a great variety of
regular or irregular shaped loads, from light and fragile to heavy and rugged unit loads.
The path may be horizontal, inclined or declined, limited by the stability of the load and the friction between the
carrying surface and the load.
MDR conveyors typically can be set‐up to the speed best suited for the work being performed, and in some
cases variable speeds can be used. They are used where unit loads are allowed to accumulate, typically with no
load to load contact, causing blocked line conditions, as a pace setter for assembly operation, for loading on and
off, or for transportation.
The purpose of this guideline is to establish certain minimum standards for use in the design and application of unit handling belt conveyors. For additional information relating to definitions and selection of common components, see current edition of CEMA Standard No. 102, Conveyor Terms and Definitions. The illustrations throughout this book are schematic in nature and represent the general nature of a particular device. The illustrations are not intended to represent the recommended safety configurations since guarding has been omitted to permit clarity in showing the operational characteristics of the device.

Application
A motor driven live roller system is best used to convey totes, cartons, pallets, poly bags, and other products
that do not exceed the limitations of the motorized rollers. Unlike other systems, weight can limit system speed
and performance. Heavier items, steep incline angles or a combination of the two may prove too difficult or
costly when using MDR.
An added value of MDR lies in its flexibility and configuration variability, from very simple to very complex. A
wide array of bed types and the absence of large drives make it a good option in limited spaces. Control options
that can range from simple transportation to accumulation to complex tracking systems make it a versatile
choice for many applications. Because of its relatively simple mechanical design, motor driven live roller
conveyor lends itself to typically an easier installation and faster Mean Time to Replace maintenance items.
There are many factors to consider when applying a MDR system. A good understanding of the system
application, rate requirements, and layout is important to making the right decisions. Options can vary widely,
so refer to the specific manufacturer for a complete list of their options. Common options include: frame
design, conveyor width, roller centers, zone length, motorized roller type, bed types, control options, and
accessories available.
MDR Conveyors are best suited for applications where multiple drives would otherwise be required. For
example, a 50 foot section of conveyor needs to be broken into five 10‐foot sections to add personnel gates to
allow access to workstations along the conveyor. Using traditional drives, this would require a conveyor drive
be added to drive each section between gates, which would be costly and require space for the drives. MDR has
the advantage of using one motorized roller per zone, regardless of the total distance traveled, so unlike the
traditional conveyor system, the number of “drives” needed for this example would not differ from a straight
unbroken conveyor. This example “system” would therefore be less expensive in both equipment and
installation labor.
There are applications where MDR may not be the best or the least expensive option. Where loads are
exceptionally heavy, an extra motorized roller may need to be added to each zone to insure the loads move
properly. Adding extra motorized rollers would increase the cost per zone. Long runs of conveyor may also be
expensive due to the high quantity of powered rollers required.
Overall system or area throughput rates are also a key consideration when choosing MDR conveyor. Motorized
rollers contain very small electric motors so it is critical to understand their power limitations and the control
schemes used to determine the actual rate the conveyor will be able to produce.
The following are some of the basic considerations governing the selection of motor driven roller conveyors and components:
Conveyor Width
Normally the conveyor is at least 2" to 3" wider than the widest unit handled. Loads may require a greater width for clearance around horizontal curves. With certain types of installations, the loads are allowed to overhang the conveyor. Guide rails are provided where required.
Motor driven roller conveyor is constructed typically in two styles which require consideration for
conveyor width.
Low‐In‐Frame (LIF): LIF refers to the position of the rollers within the frame. In this case, the rollers are
set low in the frame, allowing for the part of the frame that extends above the rollers to serve as an
integral guard rail. However, load size is limited by the distance between the frames.
High‐In‐Frame (HIF): HIF designs position the rollers above the top of the frame. Where required,
external guard rail can be added. In some systems this can effectively increase conveyor width instead
of going to the larger LIF conveyor. In some areas, HIF rollers are used to allow loads to be pushed onto
or taken off the conveyor (i.e. spurs and transfers) without lifting it over the integral guard rail.
Figure 6: Frame Style
Curves ‐ Many times curves in a system will dictate the width of the conveyors for the entire system
because the load often requires additional conveyor width to negotiate the turn. This “additional space”
depends upon the width and length of the load. The diagram and formula below shows one method of
calculating the conveyor widths required to convey a load around a curve.

Figure 7: Curve Geometry
Speed, Load, and Acceleration/Deceleration Motorized roller conveyors are capable of delivering a range of speeds and load handling. However, because
the motors used in the rollers are small and have relatively low torque (compared to traditional conveyor
drives), speed, loads, and acceleration/deceleration rates are important factors in determining the appropriate
conveyor application.
Manufacturers maintain guidelines for the maximum load that a single motorized roller can move and a
recommended maximum number of carrying rollers to be driven from each motorized roller. Different voltages,
including AC powered units are available, but 24 volt DC and 48 volt DC are commonly used in many unit
handling applications in North America.
Typically two schemes are used for the control of speed. One scheme allows for increases in the amperage to
the roller to maintain consistent speed regardless of load (within manufacturer parameters). The other scheme
sets the maximum amperage and allows the motorized roller speed to decrease as weight increases. There are
pros and cons to each scheme. It is important to understand which scheme your controller uses to insure the
rate requirements of the system are met.
Conveyor Bed The loads are supported by one of the following types of construction:
Roller--The load is carried on rollers mounted in the frames. As a rule, horizontal conveyors performs best with three rollers under the load at all times.

Figure 9: Slope Geometry
Note: Special consideration should be given to the angle of slope if starting and stopping will occur with unit loads on the incline or decline. Nose-Overs / Power Feeders These beds are used in conjunction with inclines and declines to provide smooth transitions between horizontal
and angled beds. Power feeders are used at the bottom and nose overs are used at the top. These beds will
also feature the belting, roller coating, additional motorized rollers and/or brakes to match the performance of
the inclines and declines they are associated with.
Nose-overs and Power feeders are suggested for slopes over 10 degrees and are considered a "must" for slopes over 15 degrees. Curves
These beds are used to change the direction of the load while maintaining orientation. Tapered rollers are used
to change the direction of load travel while maintaining its orientation on the conveyor. If a load is traveling
along a straight section with its long side parallel to the side frame, it will begin turning as it enters the curve so
that its long side will remain parallel to the side frame of the curve and of the next straight conveyor it comes to.
Since motorized rollers generally are not tapered, it is common practice to drive the tapered rollers from
straight motorized rollers mounted underneath or to place tapered cones on the motorized roller.
Transfers / Diverters These devices are used to remove specific loads from the MDR line and deliver them to another line or area
without manual intervention. The load is typically moved at a 30°, 45°, or 90° angle (depending on the device
type) from the original direction of travel. Diverters maintain load orientation, while right angle transfers move
the load laterally at 90°. Belts, wheels, chains or other means can be used to move the load. Some devices work
better with different types of loads.
Merge Spurs (or Junctions)
Spurs are beds that are used to feed loads onto or take them away from a straight bed at an angle (typically 30°
or 45°). These beds use a series of carrying rollers in graduated lengths to create the wedge‐shaped roller
surface.
Zones
MDR relies upon the motorized roller to power smaller sections of conveyor called zones. Zones are combined
to form standard bed configurations, with each zone typically controlled individually. With the aid of a roller
controller, sensors and control logic, each zone can accumulate throughout the system including inclines,
declines, and curves. Most MDR systems are designed to convey one load per zone and accumulation is non‐
contact.
The motorized roller must be able to transmit power to the carrying rollers in the zone. Typically drive bands
are used to transmit this power in the form of round or poly‐v for carton or tote handling, and chain for pallet
loads.
Zone Length
Zone Length requirements are based on the length of the load. One of MDR’s strengths is the ability to
accumulate loads without any contact between them; this is commonly referred to as “non‐contact
accumulation”. Generally the Zone Length should be longer than the longest load to be handled in the
system by an amount that varies based on speed and weight of the load. One exception is when the
shortest load is considerably less than the Zone Length, in these instances control logic is available to
allow for loads longer than the zone to be moved through the system. Often referred to as “flexible” or
“variable” zone length systems, these control schemes vary.
Figure 10: Zone Length
Control Options
There are multiple levels of control that can be used for MDR systems ranging from “dumb” to “smart”
depending on the requirements. Moving loads from one location to another and having them accumulate at the
end of the run is a very simple control scheme, achieved by applying a motorized roller and a roller controller
with built‐in accumulation logic. For systems that need to control load flow through a merge area to avoid
collisions, then an external control (typically from a PLC) might be used.
In some cases, customers may need to know exactly where a particular load is at all times. For these systems,
there are high level network systems that monitor the status of each sensor and roller controller, as well as the
location of individual loads throughout the system. There are also hybrid systems that use various levels of
control in different areas depending on the specific requirement.
MDR provides the flexibility for all of these situations with the same basic conveyor by varying the controllers
and wiring harnesses. Therefore the control scheme used is critical to the proper operation of MDR.
Supports Floor supports should be provided with vertical adjustment for leveling the conveyor. Adjustable hangers, such as rods with threaded ends, are generally used with conveyors at elevations over the distance specified in ASME B20.1 (Guarded By Location). Support spacing is dependent on the loading, and in some cases, on the building construction. Supports must be spaced to limit frame deflection as detailed in CEMA Standard No. 401, Roller Conveyors--Non Powered. Belting Selection A wide variety of belting types and material is available for MDR conveyor application. Some of the considerations given to belt selection are cost, strength, surface friction, abrasion, resistance, flexibility, dimensional stability, resistance to humidity conditions, oils, greases, acids, noise generated by the belt, and chemicals. The conveyor manufacturer or belting manufacturer should be consulted to select the proper type of belt to suit the application.
Section 3
Technical Data
Roller Selection
The proper selection of a motorized roller is based upon two main criteria, the required torque for the
application parameters and the required speed for throughput.
Torque Requirement
For a horizontal conveyor:
TT – Total Torque required to move load
TL – Minimum Torque required in inch*pounds to move the load
FT – Tangential Force in pounds
WL – Weight of Load in pounds
fR – Coefficient of rolling friction
R – Radius of roller in inches
N – Number of driven rollers
EL ‐ Loss per driven roller in percent (This will vary based on power transmission style)
Figure 11: Rolling Friction Coefficient
The Total Torque required is the Minimum Torque plus the system losses:
TT = TL + (TL * N * EL)
The Minimum torque required is the product of the tangential force and the roller radius:
TL = (FT * R)
Where the tangential force is the product of load weight and coefficient of rolling friction:
Ft = WL * fr
Example:
An MDR conveyor is carrying a corrugated cardboard load with weight of 40 pounds on steel 1.9 inch diameter
rollers with a single motorized roller and 6 driven rollers.
Tangential Force ‐ Ft = 40lbs * .11 = 4.4 lbs
Minimum Torque ‐ TL = (4.4lbs * 1.9”/2) = 4.18 in‐lbs
Total Torque ‐ TT = 4.18lbs + (4.18lbs * 6 * 2%) = 4.68 in‐lbs
Note: Additional factors may apply that could affect the required torque to move a product load:
Load contact of guiding devices
Change in elevation
Loads per zone
Speed Requirement
For a straight conveyor:
S – Speed in feet per minute
LP – Length of product in feet
ZL – Length of Zone in feet
PPM – Product rater per minute
The speed required is:
S = (LP + ZL) * PPM
Example:
An MDR conveyor is comprised of 30 inch zones carrying a product of 12 inches and must deliver 30 cartons per
minute.
Speed – S = (2.5ft + 1ft) * 30ppm = 105 feet per minute
Note: Additional factors may apply that could affect the required speed to move a product load:

Best Practices for
Supplemental Guarding for Unit Handling Conveyors
CEMA SBP-004 (2015) CEMA OR APPROVAL VOTING DRAFT August 31, 2015
4
1. Purpose
The purpose of this document is to outline a standardized approach to the selection and application of supplemental guarding that is used on unit handling conveyors.
These approaches flow from the collective experience of the member companies of the Unit Handling Section of the Conveyor Equipment Manufacturers Association (CEMA). Their recommendations have been compiled herein to promote a safe operating environment for personnel working next to or around unit handling conveyors. The products that Conveyor Manufacturers produce and incorporate into the end solutions that are delivered to customers have many safeguarding features. These safeguards are generally classified into one of two types. The first type is comprised of safeguards designed into the equipment and are added during the manufacturing phase of that equipment. Examples of these types of safety features are finger guards, drivetrain covers, etc. The second type is comprised of other necessary safeguards that need to be added to the equipment during the installation phase of the solution. These safeguards that are added during the installation phase are referred to as “Supplemental Guarding” in this document. The scope of this document is intended to provide information regarding the application of these Supplemental Guarding elements. 2. Definitions
The definitions of terms used within this standard will conform to those identified in CEMA Standard #102 “Conveyor Terms and Definitions” except as redefined within this section. Additional terms not currently found in CEMA 102 are defined here.
Bottom Guard- Guarding added to the underside of a conveyor to protect personnel from exposure to hazardous moving parts or other potential hazards. The bottom guard should be made of material that prevents personnel from reaching around, or reaching through openings to guard against contact to potentially hazardous moving parts or other hazards. Furthermore, the mounting method shall require the use of a tool for removal (Reference ANSI B11.19 - Performance Criteria for Safeguarding).
Barrier Guard- A single barrier installed to prevent personnel access to a particular location that contains hazardous moving parts or other potential hazards. The barrier should be sized and placed such that personnel cannot reach over, around, underneath, or through openings in the barrier to contact potentially hazardous moving parts or other hazards. The material and mounting method shall be robust enough that the barrier does not allow personnel to contact potentially hazardous moving parts or other hazards. Furthermore, the mounting method shall require the use of a tool for removal (Reference ANSI B11.19 - Performance Criteria for Safeguarding).
CEMA SBP-004 (2015) CEMA OR APPROVAL VOTING DRAFT August 31, 2015
5
Perimeter Fencing- A series of barriers installed to prevent personnel access to potentially hazardous moving parts or other hazards within a defined area. The height and placement of the perimeter fence shall be such that personnel cannot reach over, around, underneath, or through openings in the perimeter fence to contact potentially hazardous moving parts or other hazards. The material and mounting method shall be robust enough that the perimeter fence cannot be manipulated to allow personnel to contact potentially hazardous moving parts or other hazards. (Reference ANSI B11.19 - Performance Criteria for Safeguarding).
3. Human Factor Considerations People and their observed tendencies are the reasons that CEMA has found it necessary to address this topic of dealing with Supplemental Guarding. Operations and maintenance personnel may not always recognize potential hazards while walking around or under operating conveyors when performing tasks such as housekeeping or clearing faults. Conveyor manufacturers typically provide safeguards built into their equipment, but because of the complexity of conveyor systems, the manufacturers cannot always anticipate all the combinations and configurations in which that equipment can be installed. Because of that fact, conveyor installers, integrators, and end users must take into consideration the operational areas where personnel are working and provide safeguards such as supplemental guarding to protect personnel from potential hazards. Whenever changes or relocation of equipment are made, an evaluation of the equipment and personnel’s ability to access potential hazards should be conducted. Supplemental guarding needs to be incorporated to protect personnel from accessing potential hazards. Continuous analysis of worker requirements for mobility and access in the conveyor operating areas is necessary. Proper application and training concerning the use of designated pathways throughout the facility is essential. 4. Typical Operational Areas Accessed By Personnel In A Unit Handling Facility The typical unit handling facility can have various different types and combinations of equipment that are suited for a particular customer’s needs, but the areas within all facilities can be classified by one of four categories. The categorized areas are defined below because Supplemental Guarding requirements may differ between these areas:
4.1. Designated Workstations or Work Areas- A physical location where the system layout has been configured with the intent for a person to be positioned, which is supported with facilities necessary for a person to perform prescribed work duties where they are required to physically interact with the unit handling machinery or are otherwise exposed to a hazard. This position would not apply to maintenance location.
4.2. General Access Area -Designated passageways/walkways where trained
operators will travel between workstations and other areas such as break rooms, offices, restrooms, supply rooms, or other areas employees are required to travel in the course of their normal duties. During the course of travel, these
CEMA SBP-004 (2015) CEMA OR APPROVAL VOTING DRAFT August 31, 2015
6
operators may utilize stairs, ladders, crossovers, gates, etc. in order to access workstations and may pass under or adjacent to operating conveyor equipment.
4.3. Restricted Access Areas- areas of the material handling system that do not meet
the above two defined areas and do not have a normal presence of trained operators or allow operators to enter this area in the performance of their normal duties. These areas cannot contain operator workstations, designated operator walkways or passageways, and must have access restricted by a barrier or boundary that includes warning signs indicating that the area is restricted.
4.4. Guarded by Location Areas - This area is comprised of unit handling conveyors that are elevated more than 8’0” above the walking/working surface or otherwise inaccessible by other means. These areas are only accessible by qualified personnel performing maintenance activities through the use of a ladder or personnel lift. These areas do not require any supplemental guarding.
5. Supplemental Guarding Application Guidelines The guidelines for Supplemental Guarding are contained in the following sections. The application guidelines will further define these requirements based on the typical areas of the facility as outlined in section 4. These guidelines should be used to determine the selection and application of supplemental guarding that is used on unit handling conveyors; however a risk assessment taking into consideration the specific details of an individual application, such as the process defined in CEMA Technical Report 2015-01, may be used to justify deviation from these guidelines.
5.1. Bottom Guard Application Guidelines - This section will provide direction on when to incorporate supplemental guarding to restrict access from beneath unit handling conveyors to identified hazards that are between the frame rails of the conveyor.
5.1.1. Designated Workstations or Work Areas – unit handling conveyors containing exposed moving components that are considered a potential hazard shall be bottom guarded when those moving components are between the elevation of 3” and 8’0” measured from the standing surface of the designated workstation or work area and within 36” horizontal reach of the boundary of the designated workstation or work area.
5.1.2. General Access Areas – unit handling conveyors containing exposed
moving components that are considered a potential hazard shall be bottom guarded when those moving components are between the elevation of 2’6” and 8’0” measured from the standing surface or walkway of the General Access Area and within 36” horizontal reach of the boundary of the general access area.
5.1.3. Restricted Access Areas - Bottom guards are not required to be installed on
unit handling conveyors that are located within Restricted Access Areas so long as appropriate barriers and warning signs indicate the boundary of this area.
CEMA SBP-004 (2015) CEMA OR APPROVAL VOTING DRAFT August 31, 2015

5.2. Barrier Guard Application Guidelines – This section will provide direction on
when to incorporate supplemental guarding to restrict access from beside or above unit handling conveyors to identified hazards that are between the frame rails of the conveyor or a result of the conveyed loads and the path that they travel.
5.2.1. Designated Workstations or Work Areas - Barrier guards shall be
incorporated to restrict access to all potentially hazardous points that could otherwise be accessed from above or beside unit handling conveyors when the hazard points are found to be below an elevation of 8’0” as measured from the floor or walkway, and within 36” horizontal reach from any standing position in a Designated Workstation.
5.2.2. General Access Area – Barrier guards shall be incorporated to restrict access to all potentially hazardous points that could otherwise be accessed through incidental contact when the hazard points are found to be below an elevation of 8’0” as measured from the floor or walkway, and within 36” horizontal reach from any standing position in a General Access Area.
5.2.3. Restricted Access Area - Barrier Guards are not required to be incorporated
to restrict access to individual hazard points that are located within Restricted Access Areas so long as appropriate barriers and warning signs indicate the boundary of this area.
5.3. Perimeter Fencing Application Guidelines
5.3.1. Perimeter fencing is used to define a barrier between restricted access areas and workstations, work areas, or general access areas.
5.3.2. Perimeter fencing is utilized to isolate areas containing single or multiple
hazards that are not individually safeguarded. For example, when the hazard point is not confined to a specific location and will not allow the use of barrier guarding without hindering functionality or creating additional hazards, then perimeter fencing shall be applied. Also, when potential hazards are so numerous that individually guarding each hazard is not practical, then perimeter fencing can be applied.
5.3.3. Perimeter Fencing shall contain access gates with appropriate access controls as determined by a risk assessment.
5.3.4. Openings through perimeter fencing that permit conveyance of loads into, or out of, a restricted area are allowed providing that appropriate measures are taken to prevent personnel from being able to reach or pass through the openings and access hazard points inside of the restricted areas.
5.3.5. The overall height of perimeter fencing shall be a minimum of 72” (1800mm)
above adjacent walking surfaces and the opening between the bottom of the fence and the standing surface adjacent to the fence shall not exceed 6”
CEMA SBP-004 (2015) CEMA OR APPROVAL VOTING DRAFT August 31, 2015
8
(150mm). (Reference ANSI B11.19 – “Performance Criteria for Safeguarding” for additional guidance on the placement of the fence/barrier with respect to the point of hazard and circumstances which may require taller fence/barrier).
6. Inspection/Maintenance Periodic walkthrough and inspection of Supplemental Guarding is necessary to ensure that the guarding remains effective. Inspect the guarding and fasteners to make sure they are tight and secure. Inspection is also required any time work is performed in the area that requires removing or modifying the guarding.
