In many industries, laundry care is a critical issue when it comes to hygiene—especially where hygiene directly affects health or product safety. Whether it’s bedding from a nursing home or work clothes from the manufacturing sector: if textiles are contaminated with hazardous substances, simply being „clean“ is not enough.
What is contaminated laundry?
Contaminated laundry is textile material that is contaminated with substances that may be harmful to health or pose a safety risk. These include:
- Biological contaminants (e.g., blood, bodily fluids, pathogens)
- Chemicals (e.g., cleaning agents, solvents, disinfectants)
- Fine dust, organic residues, or allergens, such as those found in food-processing facilities
The actual risks arise not only from the laundry itself—but above all from improper handling: Germs and residues can transfer to other textiles, endanger staff, or contaminate entire process chains.
Two typical applications—with very different requirements
Care Facilities: Hygiene for People at High Risk
In inpatient facilities, laundry is often contaminated with germs, bodily fluids, or traces of medication. People with weakened immune systems, in particular, are sensitive even to the smallest amounts of contamination.
There are clear guidelines here:
- Strict separation between „dirty“ and „clean“ laundry areas
- Washing process with validated hygiene performance
- Regular training for staff on how to handle infectious laundry
This ensures the highest level of hygiene in in-house laundry facilities and commercial operations.
Food Processing: Protection Against Cross-Contamination
Textile hygiene also plays a key role in food-processing facilities—for example, with regard to work clothes, cleaning cloths, or aprons. Residues of proteins, organic substances, or cleaning chemicals can contaminate entire production lines.
Therefore, the following are particularly important here:
- Labeling and Separate Collection of Contaminated Textiles
- Prevention of Cross-Contamination Through Structural Measures or Separation Systems
- Safe washing processes tailored to industry-specific requirements
Why Organizing the Laundry Flow Is Crucial
Across all industries, the biggest risk factor is not the washing machine—it's the walk to it.
Key measures include:
- Pre-sorting and Labeling of Contaminated Laundry
- Physical separation or barriers between „clean“ and „unclean“
- Documented procedures with clear responsibilities
Technical Support: Separation of „impure“ and „pure“
A tried-and-true method is the so-called hygiene airlock: Laundry is loaded on the „dirty“ side and removed on the „clean“ side after washing.
Washing machines with partition technology, such as those found in DIVIMAT The systems used by STAHL enable precisely this structured process—thereby minimizing the risk to staff, patients, and end products.
Checklist: Safe Handling of Contaminated Laundry
How well is your laundry business positioned? Check for yourself:
Is there a clear distinction between „clean“ and „dirty“ laundry areas?
Is contaminated laundry collected and labeled separately?
Is the staff trained to handle infectious or hazardous laundry?
Is the entire laundry process documented and regularly reviewed?
Are machines with partition technology used?
