Large-scale inflatable amusement equipment has always been loved by children, and many people have also seen business opportunities and started operating large-scale inflatable amusement equipment. Various manufacturers are paying more and more attention to product quality and innovation. Various shapes of products have also emerged. Today, I will continue to discuss relevant knowledge with you.
Risk assessment should be carried out when designing large-scale inflatable amusement equipment, that is, to judge the possible hazards, and to identify the hazards that may be caused to human health and equipment during use and foreseeable misuse. Risk assessment should identify various hazards in the installation, use, maintenance and repair of inflatable amusement devices. The results of the risk assessment should propose targeted measures to eliminate or minimize risks.
When inflatable amusement facilities undergo major revisions or changes to important designs, new risk assessments should be conducted. Anchorage and ballast inflatable amusement devices shall be equipped with an anchor system or ballast system to enable them to be fixed on the ground. In general, the anchorage points should be evenly distributed along the periphery of the inflatable amusement device. For inflatable amusement devices with a platform height greater than or equal to 3000mm, windproof anchor points shall be added, and the distance between the windproof anchor points and the bottom of the platform surface shall not be greater than 500mm.
Each anchor point and its components (such as anchor ropes, webbing, metal accessories, ground anchors, heavy objects, etc.) of inflatable amusement devices used outdoors should withstand a pulling force of at least 1600N. The direction of force applied by the anchoring system should form an angle of 30°~45° with the ground. The direction of the ground anchor should be at an oblique angle to the direction of force. The top of the ground anchor should be rounded, and the maximum height exposed to the ground should not exceed 25mm (see Figure 1). On hard ground where ground anchors cannot be used, inflatable amusement devices should be fixed with a ballast system, and each ballast point can ensure that it can withstand a pulling force of 1600N. Reusable ground anchors should have service life requirements. The diameter of the fixed ground anchor should be ≥16mm and the length should be ≥300mm.
Under normal conditions of use, the minimum air pressure inside the inflatable amusement device should be able to ensure that the players stand and bounce when fully loaded, and have sufficient support for the structure of the inflatable amusement device and its accessories. Play areas, platforms, slopes and steps should not be touched when carrying maximum loads. The wall and shape of the inflatable amusement device should be able to bear the maximum load of the design. There should be no hard objects, sharp corners and sharp edges in the parts of the inflatable amusement device that are in contact with the players.
When using the inflatable amusement device, the players should not be able to touch any hard objects inside or adjacent to the device; after the inflatable amusement device is accidentally deflated, the players cannot touch any hard objects. Any hard objects placed in the game area and supported by air pressure shall have an additional independent support (or fixed) system, and the hard objects shall be surrounded by soft packaging. Entrance and exit should ensure that adults can pass through, so as to assist the evacuation of players in emergency situations. The entrances and exits of inflatable amusement facilities without open sides should be clearly marked.
