What is sanitation primarily concerned with?

Sanitation is fundamentally focused on removing visible dirt and debris, which is a crucial first step in maintaining a clean and safe environment. This process is essential as it helps to reduce the overall level of microorganisms that can harbor on surfaces. By cleaning areas effectively, sanitation prepares surfaces for further cleaning and disinfection steps that may follow.

While the other options involve aspects of cleanliness and health practices, they represent specific techniques rather than the primary focus of sanitation. For instance, spraying disinfectants and using antibacterial soaps are steps that often come after the initial sanitation process, as disinfectants work best on clean surfaces. Heating tools to high temperatures, while effective in sterilization, is more specific to tool maintenance rather than overall sanitation. Thus, the primary concern of sanitation is to ensure surfaces are free of visible contaminants before any additional measures are taken.
