摘要

凝胶爆破器目前在澳大利亚作为儿童玩具进口和销售。凝胶爆破器的外观与许多真正的各类枪支非常相似,其设计目的是通过压缩空气或气体推动直径约 7-8 毫米的水合凝胶小球。除昆士兰州外,澳大利亚其他各州都认为这种玩具是非法的,但大多数州的枪支立法中都没有明确写明这些物品。不过,要被视为儿童玩具,它们的动能(KE)不得超过《澳大利亚/新西兰玩具安全标准--第 1 部分:与机械和物理特性有关的安全方面》(玩具安全 ASNZS ISO 8124.1:2019)[1]中规定的 2500 J/m2。本研究的目的是确定一系列凝胶爆破器是否符合澳大利亚和新西兰标准,其射弹的动能是否小于 2500 焦耳/平方米。利用 ASNZS ISO 8124.1:2019 中概述的测试程序(澳大利亚/新西兰玩具安全标准 - 第 1 部分:与机械和物理特性有关的安全方面(玩具安全 ASNZS ISO 8124.1:2019)[1]),对一系列凝胶爆破器进行了测试。此外,还测试了一些 NERF™ 玩具和气枪,以便为公认的儿童玩具和气枪等被视为枪支的物品提供参考。NERF™ 玩具(通常称为爆破筒)通过弹簧/打击器对飞镖尾部的直接冲击、电池驱动的电动飞轮或气缸内小型活塞产生的压缩空气,以极低的速度发射泡沫弹丸。气枪设计用于发射硬塑料球(直径通常为 6 毫米),速度可达 90 米/秒以上,有可能对软组织造成伤害。结果显示,气枪发射的弹丸的单位面积 KE 值大大超过了建议的 2500 焦耳/平方米,从大约 10,620 焦耳/平方米到 69,650 焦耳/平方米不等。在测试的二十四台凝胶喷射器中,有二十台(83%)超过了 2500 焦耳/平方米,数值在 2112 焦耳/平方米到 42,645 焦耳/平方米之间。发现 NERF™ 玩具明显低于 2500 焦耳/平方米,从大约 1230 焦耳/平方米到 2129 焦耳/平方米不等。结果表明,目前在澳大利亚作为儿童玩具进口和销售的大多数经检测的凝胶冲击器(扣押物品),都很容易超过 ASNZS ISO 8124.1:2019 中规定的 2500 J/m2,因此作为儿童玩具在市场上销售是不安全的。堪培拉的澳大利亚联邦警察局(AFP)在 2019 年发表了以下声明,强化了大多数司法管辖区的立场:"澳大利亚首都直辖区(ACT)警方提醒公众,被称为凝胶爆破器的仿真枪支在澳大利亚首都直辖区是非法的"。考虑到本次研究确定的结果和澳大利亚联邦警察局的声明,凝胶爆破器不应因其声称是玩具而免受《枪支法》的管制。

Are gel blasters a safe toy? A study into their kinetic energy per unit area

Gel blasters are currently imported and marketed as children’s toys in Australia. Gel blasters closely imitate the appearance of many genuine firearms of all types and are designed to propel small hydrated gel balls of approximately 7–8 mm in diameter, by means of compressed air or gas. They are considered illegal in all states of Australia except Queensland but these items aren’t specifically written into most state firearms legislation. However, to be considered as children’s toys, they must not exceed the recommended kinetic energy (KE) of 2500 J/m2 as outlined in the Australian/New Zealand Standard Safety of Toys – Part 1: Safety aspects related to mechanical and physical properties (Safety of Toys ASNZS ISO 8124.1:2019) [1]. The aim of this study was to determine if a range of gel blasters would conform to the Australian & New Zealand Standard and have projectiles with kinetic energy of less than 2500 J/m2. Utilising the testing procedure outlined in ASNZS ISO 8124.1:2019 (Australian/New Zealand Standard Safety of Toys – Part 1: Safety Aspects related to Mechanical and Physical Properties (Safety of Toys ASNZS ISO 8124.1:2019) [1]), a range of gel blasters were tested. In addition, a number of NERF™ toys and airsoft firearms were tested to provide reference between an accepted child’s toy and items considered to be a firearm, such as airsoft firearms. A NERF™ toy (commonly referred to as a blaster) fires a foam projectile at very low velocities through direct spring/striker impact to the rear of the dart, battery-powered motorised flywheel, or by compressed air generated by a small piston inside a cylinder. Airsoft firearms are designed to fire hard plastic balls (typically 6 mm in diameter) and can achieve velocities upwards of 90 m/s with the potential to cause injuries to soft tissue. Results showed the KE per unit area of pellets fired from airsoft firearms significantly exceeded the recommended 2500 J/m2 ranging from approximately 10,620 J/m2 to 69,650 J/m2. Twenty of the twenty-four gel blasters tested (83 %) exceeded 2500 J/m2, with values ranging between 2112 J/m2 and 42,645 J/m2. NERF™ toys were found to be notably under 2500 J/m2, ranging from approximately 1230 J/m2 to 2129 J/m2. The results suggest that the majority of gel blasters (items of seizures) tested, currently being imported and marketed as children’s toys in Australia, easily exceed 2500 J/m2 as outlined in the ASNZS ISO 8124.1:2019 and are not safe to be marketed and sold as children’s toys. Reinforcing the position of most jurisdictions, the Australian Federal Police (AFP) in Canberra made the following statement in 2019: ‘ACT (Australian Capital Territory) Policing is reminding the public that replica firearms known as gel blasters are illegal in the ACT’. Taking the results determined throughout this research and the statement by AFP into consideration, gel blasters should not be exempt from control under Firearms Legislation because they are claimed to be toy.
