Work areas where microbiological cross-contamination could occur, through the air or through traffic patterns, are identified and measures are implemented. Measures can include structural segregation (barriers, walls, separate buildings or separate storage rooms), access controls, traffic patterns and segregation of people, materials, equipment and tools (dedicated tools included), and temperature controls or air pressure differentials.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
