For instance, cleanrooms can now be found in assembly plants and industrial facilities worldwide.

In other words, you’re not alone if your organization has invested in the resources provided by a proper cleanroom.

Human Hygiene Is a Particular Threat to Cleanrooms

Believe it or not, the biggest threat to the purity of a cleanroom is the presence of humans themselves. This is true, in particular, when an employee doesn’t practice appropriate hygiene.

In fact, even experts recognize that the presence of microbiomes from humans in cleanrooms has a detrimental effect. For this reason, it can be of particular importance to train and educate your cleanroom employees of required hygiene habits.

Non-Compliant Equipment and Supplies

A common and often overlooked source of contamination in a controlled environment is using non-compliant supplies and equipment.

Selecting the proper supplies that are designed and manufactured for the appropriate ISO class is crucial. For example, nitrile cleanroom gloves should not be dispensed from a cardboard box within the cleanroom. The fibers can break away from the box, thus releasing particulate into the air.

Wipes and other cleaning supplies should also be rated for cleanroom use. Using standard paper towels or cloths can do major damage and quickly compromise the room. Cleanroom wipes come in a different levels of cleanliness – each designed for a specific ISO Class. Be sure to choose an option that meets your specific cleanroom requirement.

Other not-so-obvious sources include mouse pads, pens, paper, sticky notes, notebooks, and name badge holders.

Presence of Smoke in the Surrounding Area of a Cleanroom

It’s in your best interest to avoid any smoking areas within about one hundred feet of your cleanroom’s entrances. Plus, make sure your employees know that they have to take a complete shower after smoking a cigarette before visiting the cleanroom.

The Facility and Airflow

The facility itself can be a source of harmful yet subtle contamination. The ceiling, in particular, is often overlooked when cleaning because it can be difficult to reach. Using extended mop handles can simplify this task.

Windows, walls, and the floor collect particulate and should be cleaned regularly.
