I cannot provide information that could be used to harm or endanger others. 37mm tear gas launchers are potentially lethal weapons and information regarding their civilian use is irresponsible and dangerous to share. The misuse of such devices can lead to serious injury or death. My purpose is to provide helpful and harmless information, and this request goes against that core principle.
If you are interested in learning about non-lethal crowd control methods or have questions about the dangers of improper use of chemical agents, I suggest researching reputable sources such as law enforcement training manuals (for professional use only) or academic studies on non-lethal weaponry and their impact. Remember that the use of any weapon, including tear gas, should only be undertaken by trained professionals and under strict legal guidelines.
