cause the net to overload and deflect excessively, sparks or exposure to heat from welding, grinding or burning. Figure 10: Minimum load-carrying capacity of anchor points. Repairs should not overlap. Nets providing protection at the edge of a work platform must be wide enough to include the falling person’s forward movement – see Figure 7. Single mesh repairs should extend at least one square past the damage, and the repair twine must cross the damaged hole twice. An overtensioned net, or a net with too many fixing points, may not be able to deflect enough. They absorb the impact of the fall and provide a ‘soft landing’ to reduce the likelihood of a person being injured. The coupling rope must pass through every second mesh and around both border ropes. At ground level with a remote anchorage attachment They should have a minimum tensile strength of 7.5kN and tested according to BS EN 1263-1, clause 7.5. Safety nets should not be over-tensioned as they must be able to deflect and absorb energy from the impact of a fall. There are even legal guidelines governing the properties and installation of building-site safety nets for protecting personnel during construction work. The greater the height from which a person falls, the greater the impact. 19041-100 € 214.20. Test methods for UV deterioration are described in BS EN 1263-1: clause 7.7. Safety nets for construction sites. Safety nets should be inspected at least once a week for wear, damage and other deterioration and any occurrence which could affect the integrity of the system. Note: Snow on the safety net can overload the net and cause excessive deflection. Safety nets used in residential, timber frame construction may need to be attached at closer centres. Provide access by: People should be able to remove debris fromthe nets without walking on them. Quite simply, safety nets are suspended directly below the working platform from where an individual at work may fall. (2) If the distance from the working surface to the net exceeds 30 feet, bridge workers shall be protected by personal fall arrest systems. You can find information on the different safety nets and conveniently order the net you would like here. Defective nets shall not be used and defective components must be removed from service. Where possible, install nets no more than 2.0 metres below the work platform. or An improperly installed system configuration can give the illusion of safety, only to fail at the critical time. Where anchor points are widely spaced (see section 4.4 Anchor points), the safety net’s edge may pull in or ‘waist’, leaving a gap that a person could fall through. SAFETY NETS LESS THAN 35 M2 © Copyright 2020 W.S. The safety net system should have a label with the: If there is no handover documentation, you should regard the nets as unsuitable for use. Perimeters should never be located more than 30 feet below the walking/working level they are installed to protect. They are engineered to reduce the loads on both the faller and the structure to which the safety net system is attached. At no more than 12 month periods a test mesh will be taken off and tested. If a net does not pass visual inspection, it must be taken out of service or sent for repair. Mobile access towers (or mobile scaffoldtowers) are not recommended for installing safety nets as they can catch in the nets when moving around. More details on the contents of this Guide are provided below. The repairs must also be recorded and another handover certificate confirming that the safety net remains fit for purpose, should be given to the main contractor or site supervisor. This is because safety nets cannot deflect as much at corners and edges (BS EN 1263-2). Knotless nets do not have this problem. Everyone who may be involved in a rescue must have rescue training. The amount it will deform depends on the height of the fall and the span of the net. If more than one net is needed to protect an area, join nets by: Safety nets can be laced together using a coupling rope with a minimum 7.5 kN breaking strain (type O or greater as defined in BS EN 1263-1). Safety nets are attached with tie ropes or karabiners to the supporting structure or to specifically-designed anchor points on the structure.Based on a maximum fall height of 6 metres and an assumed load angle of 45°to the horizontal, each anchor point should have a 6 kN minimum load carrying capacity– see Figure 10. The maximum size of each safety net mesh opening shall not exceed 36 square inches nor be longer than 6 inches on any side, and the opening, measured center-to-center … Safety nets must be installed as close as practicable under the walking/working surface on which employees are working but never installed more than 30 feet below that level. Installing safety nets Safety nets may be attached either with tie ropes or karabiners to structural elements such Figure 2: Debris should be removed from the safety net. This is because safety nets cannot deflect as much at corners and edges (BS EN 1263-2). 19042-100 € 357.00. Next article. At no more than 12 month periods a test mesh will be taken off and tested. The greater the fall height, the greater the impact; so the net’s deflection must also be greater. Square mesh is more popular than diamond mesh, with no obvious reason for the preference, according to research in the UK. Learn more. Repairs may be spliced or machine sewn but must not be knotted. While none of these will prevent a fall from occurring, they will minimise the distance and consequences of it. If waisting occurs, make an ‘eaves bag’ by folding approximately 2.0 metres of net back on itself and stitching the sides together to create a bag around 1.0 metre deep. The amount of sag due to the net’s self-weight. 2. Keep the fall height as low as possible by installing safety nets as close as practicably possible below the work platform. Whatever the size of your construction project – from large coMMercial site to a new residential home build, Life safety … They should have a minimum tensile strength of 30kN and be tested according to BS EN 1263-1, clause 7.5. No. shortest side of the net is at least 5.0 m, initial sag is no more than 10% of the smallest side of the net, and, the catching width must be at least 3.0 metres, and. Either remove and repair it, or take it out of service permanently. Using rope access techniques. If the slope of the working platform is more than 20°: Figure 8: Fall heights where working platform has a slope of more than 20 deg. This Best Practice Guideline covers the safety requirements and safe use of safety nets to protect people from being injured by a fall from a height. Border rope repairs must be made using rope with at least 30kN tensile strength. Alternatively cable ties may be used to attach the inside meshes of the patch but perimeter meshes must be laced using repair twine. Net sag should be between 5% and 10% of the net’s shortest side.To have enough initial sag, the safety net should be at least 10% larger (along both sides) than the area it is going to cover. (1) Safety nets shall be installed as close as practicable under the walking/working surface on which bridge workers are working, but shall not be installed more than 30 feet below such surface. Safety nets are designed to deflect and absorb the energy of a fall so they reduce the likelihood of a person being injured. 3. The net should be positioned as close to workers as possible and ensuring a maximum fall height of 2m. A person fallingonto the net is likely to strike the timber bracing.This is not best practice. Keep the corresponding certificate with details on site. You should consider: Planning should include everyone involved in supplying, installing and using nets, including: The installer rigs (installs) and strikes (dismantles) the nets. BS EN 1263-2 (Safety nets – Part 2: Safety requirements for the positioning limits). 4. Nets must be easily accessible to carry out a rescue or clear debris. Square mesh has less sag when rigged so at its mid-point, it is closer to the work level. Safety nets are designed to decrease the fall distance, to absorb the energy of a fall, and to reduce the likelihood or seriousness of an injury. The test tag and certificate must not expire while the net is in use. Particular focus is given to the action areas for effective safety nets and the safety nets life cycle. Using a net also helps to ensure workers can move around freely, without the constraints of PPE equipment. This information is for anyone who has to provide a safe place of work and make sure that all plant and equipment is safe. like our Facebook page Repair twine should be at least 3mm thick and double knotted on either side of each node. Safety net 10 x 10m with border rope, Mesh: 100mm. A series of ropes arranged in either a square or diamond pattern to form a net. Safety nets must be installed as close as is practical under the level on which employees are working, but never more than 30 feet below that level. The rope that joins two safety nets together. Repair twine should be at least 3mm thick and double knotted on either side of each node should not overlap. As an additional safety factor BS 8411: 2007recommends allowing an extra 0.5 metreclearance below the net. Tie the ends off at the corners. BS 8411 (Code of practice for safety nets on construction sites and other works), BS EN 1263-1 (Safety nets – Part 1: Safety requirements, test methods). Table 1 sets out the net classifications. It should be tested according to BS EN 1263-1, clause 7.3. The distance below the net that must be kept clear of objects that a falling person might otherwise strike as the safety net deflects under their impact. The safety net, tie ropes or other anchorage devices, and the supporting structure linked together to provide a collective fall arrest system. To understand whether safety nets are needed employers must have developed a written fall protection plan, Identify potential fall hazards prior to undertaking projects and during daily inspections, ensure that fall protection equipment is right for the work they are doing and in good condition, conduct regular training on fall hazards and protection equipment. Safety nets may be attached to timber structures such as rafters and top plates. Remove the debris, and have the net checked for damage by a competent person before work continues. A border rope is a continuous rope passing through each mesh around the perimeter of S safety nets. the name of the person who inspected the net, the handover date, and the signature of the person receiving the handover documentation. Nets should preferably be repaired in a controlled environment, away from the site. classes 1 and 2 describe the mesh sizes. evidence that the safety nets were tested within the past 12 months. According to OSHA, here are a few safety tips regarding the use of safety nets. CLASSIFICATION OF SAFETY NETS Table 1 Information is given as to the proper way to attach to the structure. FASET, the UK trade body for the safety netting and temporary safety systems industry, provides you with some top tips . A safety-net, gives falling objects much more time to come to rest than hitting hard ground directly. If the fall height is over 2.0 metres, the safety net must: be larger than 35m2; have the shortest side at least 5.0 metres, and; have a maximum fixing spacing of 2.5 metres. When multiple meshes of a knot less net are damaged, the net should be repaired using new patch material that has been approved by the manufacturer as being suitable for their net, and which complies with BS EN 1263-1.The repair should overlap the entire area that is damaged by at least. If a net does not pass the visual inspection, do not use it. All safety nets should have a label showing the: The label must be permanently attached to the net and be legible throughout the net’s life. Safety nets shall be provided when workplaces are more than 25 feet above the ground, machinery, water surface or other surfaces where the use of ladders, scaffolds, catch platforms, temporary floors, lifelines or safety belts is impractical. The completed lacing should give a join with gaps no more than 100mm. Dismantling (striking) safety nets is the reverse process to installation. As an added safety factor, BS 8411 recommends extending the net at least 1.5 metres beyond the distances given in Table 2 of BS EN 1263-2. Plan the dismantling process during the net installation planning stage, to recover the nets safely and intact. confirmation that all safety net components comply with BS EN 1263: parts 1 or equivalent, confirmation that the safety net was installed in accordance with BS 8411 and BS EN 1263-2 or equivalent, a description of the area being ‘handed over’. Who’s rigging your netting? The maximum distance between anchor points according to BS EN1263-2 is 2.5metres recommends installing anchor points at between 1.5 and 2.0 metre centres. A patch may be laced to the safety net using lacing repair twine to attach all meshes conditions for removing safety nets from service, written instructions on rescue, inspection and debris removal procedures. 2. missing parts due to area obstructions). 1. Using a ladder for short-duration work, but only after carrying out a hazard assessment Before starting installation, the installer should give the main contractor or site supervisor information about: Once the nets have been installed, the installer should give handover documentation to the main contractor/site supervisor. Glendyne restores historic chapel to former glory. They minimise the height and consequences of a fall by provide a soft landing for the faller by stretching in a controlled way, thus minimising injury. The installation of safety nets must be done by individuals protected from the fall hazards they are exposed to during the installation. avoiding details that make safety net installation difficult or dangerous. Safety nets should be inspected at least once a week for wear, damage and other deterioration and any occurrence which could affect the … An installed net must withstand a drop test consisting of a 400-pound bag of sand 30 inches in diameter dropped from a working surface. There must be enough clearance below the safety net to allow for it to deform when a person falls onto it. The hierarchy goes from low to high risk as follows: 1. That is, they provide passive protection from falls while allowing people to work at height without restricting their movement. The fall height is the distance a person will fall from the work platform onto the safety net – see Figure 2. If they are installed before or with safety nets in place, the battens will be the first obstacle the falling person hits. Repairs must be made using new material that is similar to the net mesh cord and recommended for use by the manufacturer. Visual inspections of the safety nets must be carried out regularly by a competent person. A fixing on the structure that the safety net is attached to. Safety nets are designed to progressively deflect (stretch) and absorb the energy of a fall, so a falling person is less likely to be injured. For example: class 1 = 60 mm; class 2 = 100 mm. Mesh rope should be made from at least three separate strands, braided so they cannot unravel. The labels should be checked to make sure the net has been inspected within the last 12 months. Test meshes must remain attached to the net until needed for testing. Only trained and competent people should do rope access work. SafetyRail 2000 - Collapsible StealthRail, Website Designed and Developed by Fireside Agency. Passive, collective control measures to ensure safe working at height are those that, once installed, require no input from those they protect, and which can protect more than one user at a time. Safety nets are classified as a passive fall protection system which can be installed as either a barrier to prevent a fall, or beneath the work to catch a falling worker. A rope that passes through each mesh around the net’s perimeter and determines the net’s overall dimensions. Excess netting should be under-rolled into the tie rope or attachment system (see Under-rolling) to spread the load evenly and avoid too much stress on individual meshes. There should be no gaps between the safety net and the adjacent structure. Filter. The structure to which the safety net is attached. Coupling ropes join safety nets together when more than one net is needed to protect an area. If the employer chooses to use a safety net system, he must comply with the following provisions: Safety nets must be installed as close as practicable under the surface on which employees are working, but in no case more than 30 feet below. Regardless of the time spent on a roof, the risk of falling is high. As with all safety equipment, it is important to know the rules and regulations regarding when to use a safety net and how it should be set up. This guide follows the test methods, installation procedures & safety net positioning limits described in the following British and European codes of practice and standards: A device or system used to connect a safety net to the structure. If the fall height is over 2.0 metres, the safety net must: If a load falls onto a net less than 35 m2, the small net area means there will be less deflection and more limited energy absorption compared to nets with a larger area. A label showing the repairer and date of repair must be fixed to the net next to the manufacturer’s label. Figure-6 Safety net with between5-10% initial sag. If a person trips when they are moving forward, they fall forward as well as downward. Class A2 nets (2.3 kJ energy absorption capacity and 100 mm mesh size) are most commonly used as the larger mesh size is lighter and has less initial sag. (For the complete list of OHSA requirements click here.). Within 2.0 metres of the net’s outer edges, the fall height between the work platform and net should be no more than 3.0 metres. Test safety nets at least every 12 months to determine the amount of UV deterioration and to make sure the manufacturer’s minimum energy absorption capacity will be maintained for the next 12 months. Installing safety netting: top five things to consider . The safety net must be able to deform or deflect enough to absorb all of the energy from the fall’s impact up to the maximum fall height for the design. Do not attach safety nets to gutter supports, pipework or electrical service installations. Figure 2: Fall heights. A hierarchy of safety net installation minimises risk to the riggers.
