What Materials Should Be Allowed in a Cleanroom?

Cleanrooms call for the highest standards of sanitation, and there are certain items that should be allowed in the room, and others that should never be present in the field to prevent contamination. Cleanroom notebooks, proper apparel, and approved pens are a few of the items that are allowed, but what are the other rules about what can enter the sterile field?

Items that are Typically Banned

In almost every case, food, drink, chewing gum, and mints are not allowed. Jewelry, watches, and other personal accessories are not permitted, as outside contaminants can travel on these items. Makeups and perfumes are also banned, as these can also introduce contaminants into the field.

What Should Be Used?

Gloves are to be worn at all times, as fingerprints can interfere with results. Protective hair coverings are usually required, to prevent hair and dandruff from entering the field. Street clothes must be covered by the appropriate gowns, and shoe coverings are almost always required. Cleanroom notebooks and approved pens are also permitted in the room.

Cleaning Materials

Although the cleanroom must be cleaned thoroughly and regularly, only approved materials must be used. Mops, disinfectants, cleanroom wipes, and vacuum cleaners are permitted so long as they meet industry cleanroom standards. Paper towels and cloth towels may be used for cleaning—in some cases—but are not permitted for the drying of hands.

Cleanrooms have strict rules for which items are allowed and which items are not permitted in the space. Cleaning regulations are also closely monitored to ensure that the results of any study are not impacted, and that any dangerous materials being used will not compromise the health and safety of those inside the space or the surrounding area.
