Why poor sealing causes safety failure
All points of entry for cables and pipes have to be properly sealed in buildings with high demands, such as cleanrooms, biocontainment rooms, laboratories and isolation rooms in hospitals. A first step towards increased safety and secured operations is to make sure you avoid these five simple don’ts.
- Don’t use penetration sealing methods that generate or accumulate contamination by themselves. The seals, compounds or materials must not create their own dust or peel, flake or corrode. They must certainly not provide a place for microorganisms to proliferate.
- Don’t use components or devices that are difficult to clean. The interior surfaces of walls, floors and ceilings must not have any open joints, or be difficult to access or clean.
- Don’t use sealing tactics that will force you to install pipes or route cables in a way that can create recesses. A sealing method shall not ever demand you to change your safety design.
- Don’t use weak methods, such as stiff compounds or caulking materials. Seals shall prevent particles from escaping and water from entering, so they must not crack, shatter or dent.
- Don’t use cable glands. Seals shall not require a big footprint, and they shall not oblige you to spend your time on dusty and unnecessary drilling and punching of dozens of openings.
So what to do – instead of doing wrong? Benefit from a certified system that ensures long-term protection and allows for additional cables and pipes.
