First aid products are supposed to help the user quickly and safely treat different injuries and diseases. Therefore, quality is of utmost importance. The product shall satisfy the high standards that are necessary to be safe in a life threatening situation.

Products within first aid have developed through the years and now we also have advanced defibrillators that the public may use when they are the first to arrive at the scene of a cardiac arrest before first responders arrive. It is often the first few minutes that are most important for survival in the event of serious injuries and diseases. This means a first aid product should be easy and safe to use because the person using it most often lacks experience and knowledge in emergency medical care. Even if you take a CPR and first aid course, the knowledge is easily forgotten since you don't use it regularly. Therefore it is of utmost importance to regularly (each year) repeat CPR, first aid and fire training. This can be done on your own by going through all the materials in the form of text and video but you can also take a course through an educator. This could be good for the important practical training and information that you may otherwise miss.
