Medical Personnel and Their Uniform: Evolution, Semiotics, and Epistemology of Safety Introduction: Uniform as a Boundary Between Life and Death The clothing of medical personnel represents a unique phenomenon that goes beyond mere professional attire.

The realization of the role of microorganisms in the development of infections led to a revolution in medical attire. The white color, proposed as a standard, served several functions: Semiotic: White became the color of cleanliness, sterility, and science, contrasting with the dark, "pre-scientific" past. Practical: Stains are more visible on white, which stimulates frequent changes and washing. Psychological: The white coat began to form the image of the doctor-scientist, objective and rational. Interesting fact: the first to start wearing white coats en masse were nurses — followers of Florence Nightingale during the Crimean War (1853-1856). For them, it was a symbol of hygiene, discipline, and kindness. Doctors adopted this practice later, by the beginning of the 20th century. 2. Semiot ... Read more
