Cleaning a critical environment like a pharmaceutical laboratory or manufacturing operation shouldn’t be left to chance. Specific procedures must be followed to avoid introducing dangerous contaminants into a controlled space.
An effective cleanroom utilizes positive pressure to keep clean air inside. This airflow design allows materials to enter one end of the room and exit the other.
There are guidelines for safe entry and exit when entering a controlled environment. Members of the cleaning team must:
Anyone entering this room is advised to move slowly and carefully while dressing to avoid moving or disturbing air particles.
Proper equipment can vary depending on the environment or facility. Typically, professional cleaning teams gown from the top-down, allowing disturbed particles to fall from the head to the ground. They will dress in this order:
All equipment must be inspected for damages, like rips or fabric tears. Cleanroom users should touch masks and hoods only on the inside and tuck in all hair and facial hair before adjusting. It’s also important that all garments, including gowns/coveralls, fit properly and that there aren’t any gaps. Hands should be sanitized before putting on gloves. If possible, the team should walk over a second sticky mat to remove any remaining dirt, dust, and debris that may have accumulated during this process.

Cleanroom Exit Procedures
When exiting the cleanroom, the team must exit the area slowly and similarly to how they entered. Removing equipment or de-gowning is performed in reverse order, starting with the feet and ending at the head.
Debris doesn’t take much to infiltrate a delicate environment and damage expensive equipment or property. Cleanrooms must comply with the ISO standards for air particulates. Changes in airflow patterns, air pressure, temperature, humidity, and even lighting can create uncontrolled particle levels. Even the smallest amount of contaminants can disrupt the manufacturing process. In a laboratory, bacteria or fungus could wind up in medications or on medical devices, making people sick.
