Cleaning removes contamination that is already there. Ingress control stops it getting in. Together they keep a data hall to standard, and the second is surprisingly cheap.
Sticky mats at the entrance
Peel-off sticky mats at entrances capture particles from shoe soles and wheels before they reach the hall. They only work if refreshed regularly. A saturated mat captures nothing.
Behaviour and clothing
No cardboard boxes or packaging in the hall, no unpacking inside, and no food or drink. Cardboard and foam are notorious dust sources. Where needed, appropriate clothing further limits ingress.
Filtration and positive pressure
Air filtration and a slight positive pressure keep dirty air out. These built-in measures contribute every day, with no action needed, the foundation that periodic cleaning builds on.
Key takeaways
- Ingress control is the cheapest measure.
- Sticky mats only work when kept fresh.
- No cardboard, unpacking or food in the hall.
- Filtration and positive pressure keep dirt out.
