在许多州，执法人员可以根据个人的日常角色从多种选择中选择佩戴PPE。徒步巡逻和与公众进行一般互动的人员在面罩选择上可能会更具灵活性，而特种执法部门（如特警队）则可能需要佩戴一定标准的个人防护装备。无论如何’了解可用的不同选项以及它们提供什么保护很重要。尽管全世界对PPE的了解越来越深，‘mask’ and ‘respirator’ are still being used interchangeably far too often. To put it simply, 面具s and 呼吸器s are not the same thing, and the difference is crucial when it comes to protecting law enforcement officers in high-impact situations.
Generally, procedural and surgical 面具s are thin, loose-fitting, and disposable, whereas cloth 面具s are reusable. The main purpose of these 面具s is to protect those around the wearer from large particles and droplets emitted by the wearer. Thus, 面具s are intended to provide a one-way level of protection, which is specifically to protect others from droplets expelled by the person who is wearing the 面具.
A 呼吸器 on the other hand is designed to protect the wearer from inhaled particles, including the infectious droplets of other people. Respirators accomplish this in two main ways: filtration and seal. The filter is designed to remove a high percentage of particles from the air, while the seal between the 呼吸器 and face prevents leakage around the filter. This combination is designed to restrict airborne particles from entering the wearer'鼻子，嘴巴，最后是肺。这种类型的保护对于执法人员至关重要，因为他们会经常接触空气质量下降的受损环境，从而永久性地影响他们的肺部。
PPE是官员’他们的第一道防线’re on duty. With that in mind, most 呼吸器s aren’t designed to allow for both a wide range of motion and premium protection, to protect frontline workers in the most strenuous environments. Most of the reusable 呼吸器s currently on the market for law enforcement are made of bulky, stiff material that wears on the face and inhibits range of motion.
为了解决这个问题，O2 Industries发起了 战术呼吸器II（TR2）, a premium 呼吸器 built for high impact environments, because our finest deserve better. Established in 2014, 氧气工业 has been a leader in developing comfortable, premium PPE long before the pandemic. The TR2 was developed by O2 Tactical, a research and design team within 氧气工业 dedicated to giving law enforcement the best 呼吸器y protection, without compromising performance. We’我们已经与特警队，特使团和主题专家紧密合作，执行了该任务。
The TR2 sets a new standard in tactical 呼吸器y protection. Its low profile minimizes cheek-weld interference, and its low-riding seal is eyewear compatible. It also has superior field performance, with 97% Filter Effectiveness at 0.3 microns, and is very breathable even during strenuous activity. Designed for configurability, there are multiple strap options for varying kit setups, and the TR2 is compatible with Invisio® 耳机，带有用于麦克风集成的附件端口。至关重要的是’柔软触感的医用级有机硅可与面部毛发很好地搭配，可长时间保持舒适。
