There are many historic components no longer used today, of course; some notable examples follow. As explained in the article on [[Snakebite#Outmoded|snakebite]], the historic snakebite kit is no longer recommended. [[Merbromin|Mercurochrome]] was removed in 1998 by the US FDA from the [[generally recognized as safe]] category due to concerns over its mercury content. Another common item in early 20th century first aid kits, [[picric acid]] gauze for treating burns, is today considered a hazardous material due to its forming unstable and potentially explosive picrates when in contact with metal. Examples of modern additions include the [[Pocket mask|CPR face shields]] and specific [[Bodily fluid|body-fluid]] barriers included in modern kits to assist in [[Cardiopulmonary resuscitation|CPR]] and to help prevent the spread of bloodborne pathogens such as [[HIV]].
