# 10 Critical Tips for Proper Use of Sticky Mats in Clean Rooms
Maintaining a contamination-free environment in clean rooms is crucial for various industries, from pharmaceuticals to microelectronics. One effective method for controlling contaminants is the use of sticky mats. Here are ten critical tips to ensure that sticky mats are used effectively in clean rooms:
### 1. Place Sticky Mats in Front of Clean Room Doors
To effectively capture dirt and dust from shoes before they enter the clean room, place sticky mats outside the clean room doors. This strategic positioning prevents contaminants from being brought inside.
### 2. Ensure Adequate Mat Width
Choose sticky mats that are wide enough to accommodate the majority of foot traffic entering the clean room. A wider mat increases the likelihood that both feet will step on the mat, capturing more debris and improving contamination control.
### 3. Use Long Sticky Mats
Length is just as important as width. The mat should be long enough for each person to take at least two steps on it with both feet. This ensures that more debris is captured, providing better protection for the clean room environment.
### 4. Reposition Mats for Better Effectiveness
If using a smaller, doormat-sized mat, consider repositioning it vertically in the path of traffic. This adjustment ensures that both feet step on the mat, maximizing its debris-capturing potential.
### 5. Clean the Floor Before Installation
Before placing the sticky mat on the floor, clean the surface with a mixture of isopropyl alcohol (IPA) and clean, deionized water to remove any old adhesive residues. This ensures a clean surface for the sticky mat to adhere properly.
### 6. Install on Hard Flooring Only
Sticky mats should be placed only on hard flooring surfaces. Installing them on carpets or other soft surfaces can lead to improper adhesion and potential damage, reducing the mat’s effectiveness.
### 7. Remove Top Sheets Carefully
When it’s time to replace the sticky mat’s top sheet, do so slowly to avoid stirring up dirt and dust into the air. Dispose of the old sheet carefully to minimize the risk of contamination.
### 8. Best Places for Sticky Mats
Strategic placement of sticky mats is key to their effectiveness. Ideal locations include:
– In front of clean room doors
– In staging areas inside the clean room
– In gowning areas, both outside and inside the clean room
– In hallways leading up to the clean room
### 9. Maintenance and Replacement
Regular inspection and timely replacement of sticky mats are essential for maintaining their effectiveness. Over time, the mats will lose their adhesive quality and will need to be replaced to continue providing optimal protection.
### 10. Quality and Durability
Invest in high-quality sticky mats to ensure long-lasting protection. Premium mats, such as Enviromat®, offer better durability and effectiveness, making them a wise investment for maintaining a clean and controlled environment.
By following these critical tips, you can ensure that sticky mats are used correctly and efficiently, significantly contributing to the maintenance of a contamination-free clean room environment.
