A cleanroom is an enclosed area in which airborne particles (contamination) are limited, controlled and eliminated within that space. The ability of these particles to contaminate or cause a problem is dependent upon the size of the particles. A cleanroom will deal with contamination in the following three ways:

  1. By preventing the entry of airborne particles by filtering the air that enters the room.
  2. By changing the air within the room. The frequency of this will depend on the classification of the room.
  3. By providing an area and a specified procedure when it comes to the cleaning of equipment prior to their entry into the room.

Most companies who deal with medical devices use cleanrooms as part of their day-to-day duties. People who are employed to work in clean rooms are usually known as technicians, operators or assemblers. Most clean room assembler jobs involve following detailed assembly instructions, processes, and procedures to correctly assemble medical devices. Complying with various policies, guidelines, and regulatory requirements. Reporting problems with quality, processes, equipment, or materials to the production supervisor. Completing line clearance, scrap records, training records, and other documentation as required. Maintaining a clean and organized work area to facilitate manufacturing functions.

Some clean room assemblers also have duties that relate to product inspection. Those involved in product inspection are required to be well-versed in company quality-control processes and product non-conformance standards. Inspectors in clean rooms today often use inspection devices such as light scanners or magnifying viewers in order to help them recognize defective products.

There are also certain physical requirements that are needed to perform well in the job role. The following requirements are essential and represent the minimum physical requirement necessary to successfully perform the essential duties when it comes to working in a cleanroom environment (although in some cases, reasonable accommodations can be made to assist individual workers that suffer from certain disabilities).

Cleanroom operators/assemblers are frequently required to stoop, kneel, crouch down or crawl. They are also required to lift and move things that weigh around 25lbs (and occasionally things that weigh up to 50lbs). Certain vision abilities are also required when working in a cleanroom. These include close vision, depth perception and the ability to adjust your focus. In addition to all this, employees are also required to wear gowns, boots, hair restraints and to fully comply with all of the protective clothing guidelines.
