The prevention codes use colours, pictograms and symbolic objects to convey clear messages and create a universal language.
Prevention is based on a simple principle: conveying a clear message to encourage behaviour that promotes health, safety or the environment. To achieve this, information campaigns rely on symbols that are easily recognisable to the public.
Found in transport, healthcare facilities, schools and public spaces, these symbols now go beyond their original purpose. They help to build a common language that is understood far beyond linguistic boundaries. Their effectiveness lies in their simplicity and their ability to immediately evoke an idea or an expected behaviour.
A language developed over time
Safety codes did not appear overnight. They are the result of several decades of awareness campaigns led by public authorities, associations and international organisations. The danger triangle, the no-smoking sign, the pictograms indicating an emergency exit and the colours used in signage are all examples of symbols that have gradually become part of collective habits.
Objects that convey a message
Beyond signs and posters, certain everyday objects have also become symbols of prevention. The helmet serves as a reminder of road safety, the seatbelt evokes the protection of motorists, whilst face masks and hand sanitiser are now associated with health measures.
The condom is also one of the best-known examples. Beyond its practical use, it has become a symbol of the prevention of sexually transmitted infections and of raising awareness of sexual health. Its image is now instantly recognised and understood by a large section of the public. This development shows that certain objects take on a cultural dimension that goes beyond their original function.
When conventions evolve alongside society
Public health concerns change over the decades, as do the tools used to raise public awareness. Campaigns today tackle topics as varied as mental health, the risks associated with sun exposure, pollution, diet and digital habits.
To reach new audiences, communications professionals are adapting their media and are no longer hesitant to revisit familiar approaches. Social media, street marketing and urban installations now make it possible to convey messages in a more creative and interactive way. This shift reflects a desire to bring prevention closer to everyday life, without compromising on clarity.
An example of subverting conventions
Some recent campaigns illustrate this new approach. In Paris, Substance Of Light chose to distribute sachets deliberately designed to look like condoms. The tagline, ‘Have you protected yourself this morning?’, initially prompts people to think about preventing sexually transmitted infections.
Inside, however, passers-by discover a sample of moisturiser with SPF50 sun protection. By reusing a universal symbol of prevention, this campaign reminds us that protecting our skin from UV rays can, too, become a daily habit.
Landmarks built to last
Prevention symbols now occupy an important place in our visual culture. Their power lies in their ability to convey a message quickly, regardless of the audience’s language or background. As they evolve alongside societal issues, they will no doubt continue to change in line with innovations and new forms of communication.
