Standards have been set for the work environment by the OSHA (Occupational Safety & Health Administration) a sub-agency of the US Department of Labor. These standards are to insure workplace safety. OSHA requires adequate first aid supplies to be available in the workplace but they don’t require any specific contents. The ANSI have certain standards regarding the contents.
As per ANSI standard (ANSI Z308.1-2003) “Kits in compliance with this standard will provide a basic range of products to deal with most types of injuries encountered in the workplace. The assortment of required contents was developed based on treatment for the following potential injuries: major wounds, minor wounds (cuts and abrasions), minor burns and eye injuries. It is important to note that each workplace is unique and, as such, additional first aid products should be selected to augment required contents based on the particular work environment” For a detailed list of the requirements set forth by ANSI Z308.1-2003.
