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. A hierarchy of safety net installation minimises risk to the riggers. 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. 3. The vertical distance between a work platform and the safety net. Mobile access towers (or mobile scaffoldtowers) are not recommended for installing safety nets as they can catch in the nets when moving around.

They must then give handover documentation to the main contractor or site supervisor that includes: An instruction manual for the nets including information on: The main contractor or site supervisor must keep the documentation on site for the duration of the construction project. Dismantling (striking) safety nets is the reverse process to installation. Square mesh has less sag when rigged so at its mid-point, it is closer to the work level. It is based on fall height and can be used to calculate the minimum clearance distance needed below the net, but only applies where the: Figure-4 Temporary bracing means that there is not enough clearance below the nets. System S safety nets that are less than 35 m2 are not covered by BS EN 1263-2. The test tag and certificate must not expire while the net is in use. Nets more than 12 months old must have a current test tag or label attached to the net to confirm the net met the manufacturer’s energy absorption capacity requirements at the most recent testing. UV degradation (although generally not seen with visual inspection). See Figure 9. An improperly installed system configuration can give the illusion of safety, only to fail at the critical time. A border rope is a continuous rope passing through each mesh around the perimeter of S safety nets. 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. Mesh rope should be made from at least three separate strands, braided so they cannot unravel. (For the complete list of OHSA requirements click here.). Nets should not restrict the construction work. their training and qualifications2 for installing safety nets, the testing, maintenance and energy absorption capacity of the nets, the plant they intend to use to install the nets, the anchor points and/or fixing requirements, make sure anchor points are suitable for the loads. If a net does not pass the visual inspection, do not use it. 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. Construction safety nets or Safety nets are fall arrest nets , which have the task of catching falling people. 1. They absorb the impact of the fall and provide a ‘soft landing’ to reduce the likelihood of a person being injured. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the supervision of a scaffold competent person. When working in any environment that leaves an employee open to falls, an employer cannot have enough fall protection equipment in use. It should have a minimum tensile strength of 30kN, and be tested according to BS EN 1263-1, clause 7.5. Information is given as to the proper way to attach to the structure. Repairs may be spliced or machine sewn but must not be knotted. 30 Safety nets must be installed at 30 feet or less to prevent fall injuries. There are even legal guidelines governing the properties and installation of building-site safety nets for protecting personnel during construction work. For example: class A = 2.3 kJ; class B = 4.4 kJ. Where possible, install nets no more than 2.0 metres  below the work platform. Table 2: Catching widths for maximum fall heights 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. No. Either remove and repair it, or take it out of service permanently. Using a mobile elevating work platform (MEWP). Debris can damage the net, and if left in the net is a hazard because it might: When debris falls onto a safety net, immediately stop work above and below the net. 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. See Figure 3. BS EN 1263-2: Table 2 sets out minimum catching widths for maximum fall heights – see Table 2 of this guide. Nets must be easily accessible to carry out a rescue or clear debris. make sure there is enough clearance under the nets. Do not attach safety nets to timber purlins or ceiling battens. BS EN 1263-2 only applies to safety nets over 35 m2 and where the shortest side is at least 5.0 metres. Do not attach safety nets to gutter supports, pipework or electrical service installations. 19042-100 € 357.00. Test methods for UV deterioration are described in BS EN 1263-1: clause 7.7. Nets should preferably be repaired in a controlled environment, away from the site. The safety net classification based on the mesh size and energy absorption capacity. 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. A series of ropes arranged in either a square or diamond pattern to form a net. Repairs to the net selvage should maintain the original strength of the net.Damaged tie ropes should not be used. Safety nets installed below a high-level work area reduce the distance that a worker can fall. Regardless of the time spent on a roof, the risk of falling is high. Quite simply, safety nets are suspended directly below the working platform from where an individual at work may fall. capacity must be displayed on every safety net. 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.

At no more than 12 month periods a test mesh will be taken off and tested. Note that BS EN 1263-2 allows a maximum fall height of 6.0 metres (this gives a nominal fall height of 7.0 metres from a person’s centre of gravity) but this applies only to nets that are more than 35 m2 (see section 2.10 Size of safety nets). The documents should verify the safety net system is fit for purpose, as well as giving written instructions on: The installer should also give verbal instructions on all procedures. An under-tensioned net may deflect too much and if there isn’t enough clearance below the net, a falling person may hit an obstacle or the ground. Need to use safety netting?

When a load lands on a knotted net, the knots near the impact tighten.The tightening is permanent and reduces the amount of energy the net can absorb from further impacts. When you have a building site that is more than a storey high, a safety net will also reduce the distance a person can fall. If so, make sure to 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. If unavoidable, gaps of up to 100mm are allowed. A label showing the repairer and date of repair must be fixed to the net next to the manufacturer’s label. As with any fall protection system, OSHA outlines regulatory specifications for the proper use of safety nets. Net sag, or initial sag, is the amount of deformation from the net’s own weight. They are installed with a specific tension designed to deflect and absorb the energy of an object or person that falls. Scaffold components cannot be mixed if they are from different manufac… Figure 3: Fall height with 2.0 m of outer edge of net.
