You can reduce this further by saying most electrical fires are caused by people touching things they are not qualified to touch (and by qualified I mean competent, not Certified, or anything official). If you are not comfortable with high voltage electrical work, or are not familiar with basic components of the electrical code that governs your area, then definitely don't do this. But mass-labeling the work of others as unsafe or harmful is not appropriate either.
