&gt; Imagine if she had somehow fostered a deadly pathogen on her toothbrush and through a mistake outside of her level of expertise managed to contaminate something&#x2F;herself.<p>The idea was to try to kill bacteria in the toothbrush after she used it. By definition, she was already &quot;infected&quot;. Does she need a waiver every time she is going to brush her teeth? Because I guarantee the toothbrush is not routinely subjected to that level of sterilization.<p>The only argument I can think of is that she could be creating bacteria more resistant to whatever was that she was trying to use to disinfect. But if that&#x27;s a problem, then we should all focus on banning antibacterial soap first.<p>Excess paperwork never solves any problems.
