What Can I Take and Not Take Into a Cleanroom?

A cleanroom is a controlled environment where the concentration of airborne particles is kept at a minimum to prevent contamination of sensitive products or materials and improving yield. These environments are commonly used in industries such as pharmaceuticals, semiconductors, and medical device manufacturing, aerospace, where even the smallest particles can cause defects or damage to products.

In order to maintain the integrity of a cleanroom, there are strict rules about what is allowed and not allowed inside the controlled environment. Some common rules for cleanrooms include:


  • No food or drink is allowed inside the cleanroom. This is to prevent the introduction of bacteria or other contaminants that could potentially contaminate the products or materials being handled in the cleanroom.

  • Personal items such as bags, purses, jewelry, wearing makeup, and coats are not allowed inside the cleanroom. These items can carry contaminants and could potentially contaminate the cleanroom environment.

  • Only approved materials and equipment are allowed inside the cleanroom. This includes items such as cleanroom-approved clothing, gloves, and masks, cleanroom paper as well as tools and equipment that have been specifically designed for use in cleanroom environments or wiped properly to be used in the cleanroom.

  • Proper cleanroom protocol must be followed at all times. This includes following strict procedures for entering and exiting the cleanroom, as well as for handling products and materials inside the cleanroom.

  • Regular cleaning and maintenance of the cleanroom is essential to maintain the integrity of the controlled environment. This includes regular cleaning of surfaces and equipment with appropriate wipes and cleaning solutions, as well as regular testing and monitoring of the air quality inside the cleanroom.

  • Overall, the main rule for cleanrooms is to prevent the introduction of contaminants into the controlled environment. By following strict rules and protocols, cleanrooms can maintain the high levels of cleanliness and control needed to protect sensitive products and materials.
