Allergen segregation and staff protection

Procedure

1. Assess worker exposure and contamination of other preparations. Select a dedicated area and equipment where the assessment requires it.
2. Keep separately labelled containers and tools for each allergen. Do not rely solely on colour coding without written identification.
3. Control dust with suitable engineering containment. Avoid dry sweeping and compressed air that disperse residues.
4. Select task-appropriate PPE and organise safe removal, clothing changes and waste handling. Specifically assess workers with relevant sensitisation.
5. Demonstrate cleaning using a method suitable for the specific allergen and surface. ATP testing or simple disinfection does not establish allergen removal.
6. Define an acceptable residue and verification plan with scientific justification. Release the area for other work only after the required checks.

Edition-specific detail

Cleaning assessment uses recovery from actual surfaces and an allergen-suitable method. Report not detected with LOD/LOQ, surface area and acceptance criterion; it does not mean zero allergen. If shared equipment cannot be demonstrably cleaned, use dedicated equipment or refer the work.
