  • Cleanroom Operators – It’s best to consult everyone and anyone who will have a hand in working within the cleanroom, this includes maintenance and IT departments, which may need to maintain the cleanroom’s functionality, as well as production teams working within the cleanroom and what their requirements for their role are.
  • Cleanroom classification  You will want to make sure your cleanroom is not over-specified for your work, as the cleanroom will need to be consistently maintained to its classification, which can get more expensive the lower the ISO grade.   This is a crucial decision in investing in a modular cleanroom, so it’s important to get it right.  By taking the appropriate measures of step one, you should be able to gauge what’s needed from those who will be working with the cleanroom.
  • Protrusions and outcrops – You will want to consider the space in which your portable cleanroom will be housed: is there anything sticking out from the walls or ceiling?  Common fixtures include: power sockets, lights, smoke detectors, and built in shelving.
  • HVAC ducts – HVAC ducts should not be internally insulated or, if they are, the insulation needs to be made from Mylar or Melinex to avoid particulate contamination.  You will want to consider if there are any other sources of partical contaminate and remove as many as possible from the environment.
  • Specialised equipment – Your cleanroom specifications will need to take into consideration any and all equipment that will be housed in the room, as well as clearances for doorways.
  • Power sourcing – Your existing electrical infrastructure will need to be checked to make sure it can handle the additional load requirements set by your portable cleanroom, as well as enough power to handle any additional expansion in the future.  Map out where your power points in the room are, and plan to align your equipment accordingly.  All power points should be recessed in the wall with no sharp edges as not to compromise the integrity of the cleanroom.
  • Lighting – Lighting controls should be located with ease of access outside the cleanroom itself, and should be adequate to task.  Ensure that exit and emergency lighting are available in and out of the cleanroom in case of an emergency or power cut.
  • Containment – Usage of the cleanroom needs to be considered when choosing components such as clean versus dirty corridors, airlocks, etc.
  • Gowning rooms – Have you considered the need for gowning and de-gowning rooms?  Do you have the space to accommodate a changing area, as well as multiple personnel occupying it at one time?
  • Windows – Have you planned for viewing windows so personnel within the cleanroom can be supervised?
  • Surfaces – Are the materials selected for the walls, floors, and surfaces within your cleanroom compatible with the type of cleaning agents you regularly use?
  • Waste flow – Consider all forms of waste that will be produced in and around the cleanroom, including used garments.
  • Security – Modular cleanrooms can be fitted with electronic access controls to provide enhanced clearance security, and you may want to consider installing CCTV cameras outside of the cleanroom.
