The guidelines should not be resorted to as a substitute for professional advice for any purpose. 3

4 Purpose These guidelines benchmark the standard for the design, manufacture and installation of external rotary milking platforms. The purpose of these guidelines is to identify and analyse risks or hazards in and around working rotary platforms and provide guidelines for the management of such risks to abate possible injury or death to humans or animals. The risks discussed in these guidelines are in relation to human or animal safety only and do not extend to other parameters such as electrical safety, environmental or building compliance etc. Note: The specifications and recommendations in these guidelines relate to rotary platforms designed for milking cows. Designs of rotary platforms for the purpose of milking sheep or goats should take into account all the risks identified herein, however, the guidelines must be adjusted accordingly. Background These guidelines, initially released in 2006, were the result of working groups including Department of Labour, OSH, New Zealand Milking & Pumping Trade Association Incorporated (NZMPTA), Federated Farmers, farmers and manufacturers of rotary milking platforms and milking equipment. They have been reviewed in 2014 by the NZ Milking & Pumping Trade Association in consultation with industry stakeholders being Rotary Milking Platform Manufacturers and Milking Machine Equipment Manufacturers within New Zealand, and have been adopted as the New Zealand Guidelines for the Design of Safe External Rotary Milking Platforms.

5 Introduction To These Guidelines In order to identify risks the rotary platform has been split up into Zones as per the diagram on page 7 of these guidelines. These guidelines analyse the risks in the various zones firstly with the platform running in the forward direction, then the reverse direction. Other operations such as herd testing, cleaning and maintenance are also considered. A logical process has been followed to identify possible risks. In the guidelines contained within this document many references are made to safety stop devices. Larger platforms have longer stopping distances. A safety stop must cause the platform to stop before any injury results. Where stopping distances are a concern the safety stop device shall be situated and activated an appropriate distance ahead of the trapping point. To avoid the safety device becoming a hazard itself, it shall be able to move from the point of activation to the trapping point. Emergency stops, either button or rope type, shall be connected so that power is immediately cut to the platform drive motors. The inverter ramp down stop function shall not be used in the emergency situation. Some damage to the platform drive units may be caused if the emergency function is used as an operating stop. The intention is for the emergency stop to be used only in emergency situations. The definition of emergency stop does not extend to include auxiliary braking devices. If the identified hazards do not exist in any specific installation due to its specific design then the safety feature described for that general area is also not required. Similarly, if hazards identified in these guidelines are introduced by the addition of other systems or components i.e. Washing, Cleaning, Feed systems and Automation components, compromising the specified safety clearances, then additional modifications shall be introduced to maintain the specified safety clearances. These guidelines benchmark the standard for the design manufacture and installation of external rotary milking platforms in New Zealand. If deviating from the guidelines consideration shall be given to the safety benchmarks set out in these guidelines. Additional hazards, not identified in these guidelines, may be present around rotary milking platforms. Such hazards should be treated in a manner that will eliminate or minimise any risk of injury and should comply with relevant safety standards. The guidelines have referred to Anthropometric Data, AS :2014 Safety of Machinery. Some compromises have been made with reference to this publication when setting these guidelines, to enable the design, manufacture and installation of a productive and effective working system. Gap measurements stated for the purposes of trapping hazards to humans are assuming the dimensions of the average New Zealand adult body and do not provide for trapping points for children or adolescents. It is strongly recommended that children and unauthorised persons should not be in, or around, the vicinity of the structure or components of any milking platform or machinery. Always ensure you are familiar with, and compliant with, relevant industry Safety Standards and Codes, including the NZ Health and Safety at Work Act

6 Glossary Bail: This is the structure that separates the cows from each other on the platform. Generally vertical and up to a height of 2m above the deck of the platform, it is rigidly fixed to the deck of the platform. Breech Rail (or Rump Rail): This is a circular rail located at the outside diameter of the platform edge. It stops the cows from backing off the platform into the operator area and extends almost all the way around the platform. It is fixed to the floor, roof or wall of the building in the operator area. Breech Rail Support: These are pipes that are mounted to the floor, wall or from the roof at one end, and support the breech rail at the correct height above the platform. Bridge: The bridge is a section of the floor raised up to the platform deck height to enable the cows to walk on and off the platform. It is typically 35-50mm from the platform, is 2 to 3 metres in length and does not move. Cow or Cows: Where cow or cows is used in this document this also references to other dairy animals such as sheep and goats. Hinged D Gate: This is a short radius gate attached to the entry race that separates cows moving into the platform from those moving off the platform. It is hinged for safety only. It is mounted at a fixed position on the bridge. Kick Rail: A fixed circular rail below the breech rail to stop cows kicking the operator. Platform: The large circular platform on which the cows stand. It can have an open centre with a considerable height differential between the platform deck and the floor level. It rotates at a low speed with respect to the operator s normal position. The rotation is driven by some form of mechanical drive system like a powered wheel. Platform Ribs: These are steel ribs that support the platform. They radiate out to the edge of the platform, underneath the platform. 6

Gap between kick rail and bails 10. Vertical gap between breech or kick rail and platform or platform accessories 11. Kick rail height Typical entry safety switch 8

9 Hazard 1: Breech rail at entry Description: Cow and operator trapping point between bail structure and breech rail at entry. Guideline: A breech rail safety switch shall stop the platform. The platform can be manually reversed. Forward operation shall be manually initiated again if the pressure switch is released. Hazard 2: Kick rail at entry Description: Cow and operator trapping point between bail structure (and cup removal mechanism, if fitted) and kick rail at entry. Guideline: The breech rail safety switch shall be able to protect both breech rail and kick rail trapping points. Consider options of twin arm or dual pressure type safety switches. Hazard 3: Kick rail to breech rail connection at entry Description: Operator trapping point between vertical kick rail connection to breech rail and moving bail structure or projections from bails. Guideline: Ensure that breech rail safety switch described in hazards 1 and 2 shall protect against hazard 3 as well. The kick rail in the entry area shall butt into the same entry support post as the breech rail eliminating the need for a vertical connection to the breech rail at this point. Although many designs use a single switch, separate switch devices are acceptable. Ensure that the breech rail and the kick rail are protected by a safety switch or switches. Also ensure that the kick rail butts into the same support post in the entry/exit area as the breech rail. Also ensure that kick rail connections to rump rail are as specified in hazard 6. 9

10 Zone 2: Deck Level Platform Running Forward (refer diagram on page 7) Hazard 4: Description: Guideline: Hazard 5: Description: Guideline: Clearance between platform and parlour walls (A wall is defined as a solid structure greater than 900mm in height) Where the gap between the parlour wall and the platform is too narrow, operators are forced to walk too close to the platform and are at risk of getting kicked. The minimum gap between any adjacent wall and the outside edge of the platform or other rotary platform accessories shall be 1100mm to allow traffic to proceed around the platform 500mm away from platform. Kick Rails Where ever the kick rail is not continuous and it is restarted the vertical connection to the breech rail presents a trapping point against the bail structure or any projections from the bail. Full kick rails shall be installed as a standard feature. The kick rail shall be installed continuously around the platform. Hazard 6: Vertical connections between kick rail and rump rail Description: Numerous vertical connections between the kick rail and the breech rail present a trapping hazard between the vertical bail structure or bail projections. Guideline: The number of vertical connections to the breech rail supports shall be restricted to the number of breech rail support posts, a minimum of 3.25m apart. The kick rail pipe diameter shall be increased to 32NB to suit above arrangement. Breech rail to kick rail connectors shall be 200mm away from the stalling. Hazard 7: Description: Guideline: Hazard 8: Description: Guideline: Gap between breech rail and kick rail A trapping hazard may exist if operator inserts head through gap between breech rail and kick rail. The gap between breech and kick rail shall be less than 155mm (i.e. narrow enough to prevent access for a head) or greater than 200mm (i.e. wide enough to prevent a head from being trapped). Gap between breech rail and bails Trapping point between the bail structure and the breech rail. The gap between the inside face of the breech rail and the bail structure needs to be sufficiently large enough to avoid trapping arms and hands but also needs to be small enough to ensure this does not become a cow trapping point or cow flow disturbance. The inside face of the breech rail shall be 75mm away from the bail structure. The gap between the kick rail support pipes should also exceed 200mm at the breech rail level. Where a bail is of the teardrop design style and rails extend beyond the breech rail, the 10

11 trapping point at the entry rails shall be protected by a breech rail safety switch in the entry and exit area as describe in Hazard 1. Hazard 9: Description: Guideline: Gap between kick rail and bails Trapping point between the bail structure and the kick rail. The gap between the inside face of the kick rail and the bail structure needs to be large enough to avoid trapping arms and hands but also needs to be close enough to be effective as a kick rail. The inside face of the kick rail shall be a minimum of 75mm away from the bail structure. The gap between the kick rail support pipes should also exceed 200mm at the kick rail level. Where a bail is of the teardrop design style and rails extend beyond the breech or kick rail, the trapping point at the entry rails needs to be protected by a breech rail safety switch in the entry and exit area as described in hazard 1. (See sketches in Hazard 8) Hazard 10: Vertical gap between the breech or kick rail and platform or platform accessories Description: Operator at risk of trapping hands and arms between the breech or kick rail and platform accessories. Guideline: The gap between the underside face of the breech or kick rail and the top side face of the stall work or any accessory mounted on the platform shall be a minimum of 50mm. If any such part of the bail or accessories exist protection shall also be provided by a safety switch in the entry and exit area as described in Hazard 1. Hazard 11: Breech rail and kick rail height Description: Operators at risk of being kicked if kick rail is not positioned correctly. Guideline: The breech rail shall be positioned between 800 and 950mm above the platform. The inside face of the breech rail shall be at the same vertical plane as the inside face of the kick rail. 11

12 Hazard 12: Position of vertical floor mounted breech rail post from platform Description: Operators at risk of being trapped between platform and vertical floor mounted breech rail post. Guideline: The gap between the platform or the platforms outer most rigid projections and the floor mounted breech rail posts shall be at least 350mm providing that the gap between the support post and the wall is 750mm or more. Other breech rail post designs that comply with other aspects of the guidelines and are intentionally positioned in excess of 1100mm away from the platform are also acceptable. Hazard 13: Design of roof mounted breech rail support Description: The gap between the vertical roof mount support dropper and the bail structure can present a pinch point. Typically a 45 degree angle is used to connect to the breech rail which encroaches into the required safety space. Guideline: The vertical roof mounted support dropper shall be fitted 500mm away from the bail structure with a 30 to 45 degree connection from horizontal bend junction to the breech rail. Hazard 14: Platform edge and bridge face at exit Description: The gap between the platform edge and the bridge face is a trapping point for exit operators limbs. This trapping point is aggravated if the platform has ribs that project below the deck. Guideline: An emergency stop switch shall be fitted within reach of the pinch point between the platform and the bridge face, or other suitable device, that will stop the platform before any injury to exit operator is caused. A Teflon or rubber protector flap may be an option with certain platform/equipment arrangements. Where the platform has ribs that project down below the outer ring, these projections shall be chamfered back or manufactured with large radiussed corners. An alternative safety protection is to extend the platform outer ring down below the rib level. Hazard 15: Multiple identified and unidentified hazards requiring emergency stop Description: The current rope switches used by most platform manufactures are an operating control device. Guideline: This switch shall now be supplemented or replaced with an emergency stop rope pull switch. This emergency stop rope pull switch shall also have a reset button that shall be activated before the platform can be restarted from the console. The switch shall also be installed as a rapid stop function. This switch shall also be accessible in the entry exit area as it will provide additional safety for operators in this area. In order to reduce costs platforms can be quoted with the emergency rope safety stop and the regular stop start rope switch can be quoted as an extra. Hazard 16: Slippery platform deck surfaces Description: Slipping cows can cause injury to operators or AI technicians etc. Guideline: Steel platforms decks shall be made from a suitable tread plate material. Concrete platforms require a hardened and brushed surface. Concrete should be 40 mpa. 12

13 Hazard 17: Electrical shock Description: Control consoles for platform operation are always installed in a wet area. There is a risk of electrical shock. Guideline: Control consoles should operate on 48 volt circuits or less eliminating the risk. Higher voltage circuits may be acceptable, however, all electrical installations must comply with the Electrical (Safety) Amendment Regulations 2012 and AS/NZS 3000:2007. Hazard 18: Platform speeds Description: Platforms are often run faster than a short milk out time rotation speed when being used for other activities. Platforms are also often rotated at high speed to the cleaning park point to save time. High speed operating platforms especially in non- milking activities pose a greater risk. Guideline: The maximum platform rotation speed should not exceed 5 seconds per bail at any time for cows and 3 seconds for a sheep or goat. Zone 3: Exit Platform Running forward (refer diagram on page 7) Hazard 19: Gap between hinged D-gate and bail structure Description: Risk to cow or operator caught in exit area between bails and hinged D-gate. Guideline: The D-gate shall be hinged in the forward direction and shall swing open to allow a full 500mm clearance from bail. For clearances of less than 500mm the D-gate shall be connected to a safety switch. The clearance in the closed position shall be a minimum of 75mm. Zone 1: Entry Platform Running in Reverse (refer diagram on page 7) Hazard 20: Gap between D-gate and bail structure Description: Risk to cow or operator caught in entry areas between bails and D-gate. Guideline: The gap between the bail structure and the D-gate shall be no less than 75mm. A reverse jog switch shall be installed in the platform control console. This switch shall only reverse the platform while the operator is close to this critical area and has his or her finger on the button. This manual function will require operator attention in this area and will minimise the risk. Zone 2: Deck Level Platform Running in Reverse (refer diagram on page 7) Hazard 21: Platform edge and bridge face at cow entry Description: The gap between the platform edge and the bridge face is a trapping point for operators limbs. This trapping point is aggravated if the platform has ribs that project below the deck. Guideline: A reverse jog switch shall be installed in the platform control console. This switch shall only reverse the platform while the operator is close to this critical area and has his or her finger on the button. This manual function will require operator attention in this area and will minimise the risk. A safety interlock may be fitted over the nip which forms as the platform reverses. Where the platform has ribs that project down below the outer ring, these projections shall be chamfered back or manufactured with large radiussed corners. An alternative safety protection is to extend the platform outer ring down below the rib level. 13

14 Zone 4: Operator Floor Platform Running in Forward or Reverse (refer diagram on page 7) Hazard 22: Protection from platform running gear and other rotating equipment below the platform Description: Operators are exposed to multiple risks if there is any possibility to make contact from the operating area with the running gear or other rotating equipment. Guideline: All running gear shall be protected by a continuous rigid skirt. Where not practical all rollers shall be protected by individual shields if not already obscured by pipe work and other milking equipment. If there is any remaining open access to the central pit area, this opening shall be protected to eliminate access. NB: Running gear and milking equipment should be treated separately. Above Image: Graphic shows the outside of the platform without a skirt. Note: Operators may be exposed to risk of moving equipment and rollers. Rollers exposed especially when not hidden by equipment. Hazard 23: Removable veterinary platform Description: Trapping point between stationary rails and rotating platform parts for operators on removable veterinary platform. Guideline: Where a veterinary platform is installed there must be an emergency stop within easy reach of the operator at all times. Zone 6: Pit Area Platform Running in Forward or Reverse (refer diagram on page 7) Hazard 24: Access to central pit area Description: Safe access is required to central pit area. Access is often provided by a set of steps or ladder fixed to the rotating platform. Guideline: All Dairies shall have access provided to the centre pit area via an under or overpass. Only where this is not practicable will access be via other means. Access via the bail shall have 14

15 a gate in the breast rail and in the feed bins to allow access without climbing. A ladder shall be provided to transition from the platform to the pit floor. Steps / Ladders shall comply with current NZ Building Code. Steps or ladders that allow the operator to access the pit at 90 degrees to the typical cow position shall be installed so that the operator gets off the platform as it is moving away from them in the forward direction. The specified riser dimension between tread plates may result in a non-standard dimension between last step and pit floor. Hazard 25: Access to central pit through underpass Description: People accessing the central pit area through an underpass may find a trapping point when the receiver or other low level equipment passes over the underpass. Guideline: An interlocked stop switch and safety gate or an emergency stop shall be easily accessible from within the underpass. In some installations a fixed cover plate between the moving equipment located above the head of a person using the underpass shall be installed as an alternative solution. Where the underpass and its riser into the central pit area is a suitable depth and distance beyond the rotating equipment, no additional protection may be necessary. Hazard 26: Risk of moving equipment to operators involved in herd testing Description: Exposure to multiple risks when herd testing inside a rotating platform. Guideline: An emergency stop or rope emergency stop shall be installed in the central pit herd testing area. Hazard 27: Injury to maintenance staff in pit area Description: Maintenance staff could be at risk if the platform was inadvertently started by an operator unaware of the maintenance situation. Guideline: A lockable isolator must be fitted to all platform drive units to prevent rotation during maintenance; taking wiring regulations for variable frequency drives into consideration. Refer New Zealand Handbook Electrical installations in dairy sheds SNZ HB 6117:2014. Hazard 28: Platform control Description: Platform control panels with equal functionality at attach and detach positions can expose operators to platform movement risks. Guideline: The attach operator console shall always be the master control console and shall be the only console with a reverse switch. All Zones: Hazard 29: Limited safety signage alerts Description: All identified risks require safety alert signage. Guideline: A safety sign package shall be provided with the platform. Comment shall be made on signs that safety gaps are designed for adults, and children are not necessarily protected. Operators manual shall include a safety chapter. A wall chart of basic safety precautions shall be installed near the operator. This chapter shall include instruction on restricted milking parlour access, and off limit areas for visitors and children. 15

16 Examples of Safety Signage Good quality signs shall be placed at all risk points and not necessarily limited to the examples below. All parlour entries shall display clear warning signs. People in the pit to be alerted to possible risks. Warning signs required at pinch points between platform and bridge. Operation warnings on consoles and in office areas. Safety signage can be ordered from safety supply stores. 16
