Contamination Control in Cleanrooms
Cleanrooms are designed to control what cannot be seen. Even microscopic contaminants transferred during everyday operations can compromise cleanliness standards and disrupt critical processes. Maintaining a controlled environment means managing contamination at every stage of movement within the facility.
Consequences:
Product contamination
Reduced operational efficiency
Regulatory
non-compliance
Compromised process reliability
Product rejection and waste
Increased operational costs
Production downtime
Contamination between areas
The role of floors in contamination control
Floors are among the most active contamination transfer points in controlled environments. Contaminants accumulate on floor surfaces and be unintentionally carried throughout the facility by shoe soles, wheels and equipment moving between areas.
Entrances, corridors and transition zones are particularly critical because they connect environments with different hygiene requirements. Even routine movements can contribute to the spread of contaminants from lower-risk areas into more sensitive spaces.
Lower-Risk Area
Movement
Contamination accumulate on the floor
People, carts and material move between areas
Sensitive area
Contaminants can be transferred into high-care areas
Understanding how contaminants move at floor level is an important step in reducing their spread throughout the facility.
Washable contamination control mats:
an additional barrier against contamination
Creating an effective barrier at critical access points helps prevent contaminants from being carried from one area to another during everyday movements.
HelloMat washable contamination control mats are designed to capture contaminants from shoe soles and from wheels, helping to reduce contamination transfer where it matters most.
Their stable, washable surface ensures reliable long-term performance even in high-traffic environments.
Integrated silver ion technology provides continuous antimicrobial protection by helping to inhibit bacterial growth on the mat surface.
Combined with regular cleaning procedures, this contributes to maintaining cleaner and more hygienic environments throughout the facility.
