Testing Cleanroom Environments

Testing Cleanroom Environments

All Cleanroom process environments must remain unfailingly clean, so merely filtering the factory’s air is inadequate. To minimise particle contamination it is important to build separate environments, called cleanrooms. These areas allow particle limits to be maintained at measurable and controllable levels locally.

Testing Cleanroom Environments

Clean rooms environments achieve these acute cleanliness levels by maximising laminar airflow and minimising particle traps. Laminar airflow is air moving in one direction, which allows particles to be swept away from an area within the cleanroom. Particle traps within a cleanroom environment are areas where particles gather and escape laminar airflow, such as the corners of the rooms and behind machinery and instrumentation, careful cleanroom design and placement of room furniture can minimise these areas.

In efficient cleanrooms HEPA filters installed in the ceiling allow filtered air to pass down toward the floor. The floor tiles have small holes that allow the air to pass under the floor, where air-returns (air ducts) transport the air back to the ceiling HEPA filters. This filtration process can exchange the clean room’s entire volume of air more than thirty times per hour, resulting in a very clean environment while minimising the movement of air particles.

Clean Room Commissioning 

To further reduce contamination within a cleanroom requires personnel to wear protective gowns, hair and beard covers, hoods, overshoes, and gloves. In the cleanest environments, personnel all the aforementioned clothing as cleanroom apparel is extremely important in controlling micro-contamination to contain the particles emitted by people.

We undertake the Following Cleanroom Validation Services:

  • Airborne Particulate Testing
  • Air Change Rate Calculations (ACR)
  • Air Volume Flow Rates
  • Differential Pressure Measurements
  • HEPA Filter Integrity Leak Testing – DOP Method
  • Temperature, Humidity, Light and Noise Level readings
  • Recovery Performance testing
  • Airflow Visualisation tests, supported by a full written report
  • We also provide temperature mapping of rooms and storage facilities, in order to meet customers regulatory and QA requirements.

Potential Hazards In Clean Room Facilities

Potential Hazards In Clean Room Facilities

There are many potential hazards in clean rooms, so maintaining the health and safety and adhering to the high standards of a controlled cleanroom environment requires thorough training and routine testing and inspections. Maintaining safety standards scan be quite a challenge as the unpredictability of things that can go wrong and ultimately contaminate a cleanroom are quite extensive.

Clean Room Vailidation and Commissioning

Clean-room-testing-services

Some common examples cleanroom hazards include:

  • Electrical Outlets – check that your electrical outlets are properly sealed.  Sometimes, small insects can crawl through outlets as well as airborne duct and contaminates.
  • Electrical Trunking – ensure all electrical trunking is completely sealed where it terminates through the room/building envelope.
  • Mechanical Pipe Runs – check that your pipes etc. are properly sealed where they terminate through the room/building envelope.
  • Rubber Coving to Walls and Floors – where different finishes have been bonded together, i.e. walls and floors, ensure that the rubber bonding strip has not begun to de-bond from the finishing’s, this can lead to air leakage paths and also allow dust and other contaminates into the clean room environment.
  • Holes in the HEPA Filters – Sometimes employees accidentally damage HEPA filters by lifting mop handles to high and hitting the underside of the HEPA filter.
  • Double Doors – when you’re designing and building your cleanroom, do you have a double door installed? You should have a double door to bring things in and out, yes, even during the building process to bring equipment in and out of the area.
  • Pass Through Areas – do you have to bring a lot of equipment and parts into the cleanroom? If so products and supplies can go through the pass through in the form of a wall mounted or floor mounted cart pass through.
  • Flooring – what type of flooring has been installed within your cleanroom? If the floor is vinyl it is not an ESD floor. All equipment must be able to be properly grounded to the floor when you’re using ESD chairs, carts, chairs etc.
  • Mobile Phones – if you need your mobile phone and/or walkie-talkies in the cleanroom for communication purposes, it should not be clipped on the outside of your coveralls. They may fall off and damage microchips etc. in all instances if you do need communication devices you can wear small cleanroom waist bag etc. which reduce the risk of damage to your surrounding area.

Cleanrooms play critical roles in maintaining contamination free production environments for critical processes. To ensure your cleanroom is working as designed it is essential that a well planned and executed cleanroom testing,  certification and maintenance program is undertaken for operation and regulatory compliance.
