02 / Complete-line interfaces
Design normal production and the conditions that disturb it
Ponding, inaccessible channels, trapped soil, aerosol, pest entry, cross-zone flow and insufficient capacity can make drains persistent contamination sources. Map raw materials, packaging, product, people, tools, chemicals, waste, air, water, power, heat and information from site entry to dispatch. Review doors, airlocks, level changes, drainage, cleaning access, maintenance removal routes, forklift paths and every boundary between production and support rooms. Review startup, steady production, short stops, restart, low or high demand, format or recipe change, cleaning and shutdown. The interface must protect both the incoming condition and the requirement of the next module.
