Cleanroom certification involves checking specific cleanroom parameters to ensure they are built to the right set of requirements. The rooms are also routinely tested with the same factors to ensure that the quality has not changed during operations within the room.
When a cleanroom is certified to a specific class, it must operate to standards that meet or exceed the ISO parameters for that class under a particular occupancy status.

How to use an extractor hood
Fume hoods are made to keep lab workers secure when handling dangerous substances. They filter the air to prevent inhaling toxic particles that can lodge in the lungs and cause serious health consequences. Fume hood certification is important.
For range hoods to provide protection, users must follow basic safety practices. No matter how well a fume hood is designed, it will not be effective unless proper safety measures are taken in the laboratory.
Before using a range hood
Familiarize by self with the chemicals. One must know potential safety hazards when working with hazardous material. Follow the safety instructions listed on the safety data sheet (SDS).
Verify the fume hood's certification label. Every year, fume hoods should be inspected. The certification label indicates when the hood was last tested and its average forward speed. The average facial velocity varies from 0.5m/s to 0.6m/s.
Make sure the exhaust is working properly. The main job of a range hood is to extract dangerous vapors and fumes from the area. Check the baffles to make sure they are not clogged. If a suspect changes airflow while working, take a break to check things out.
