Cleanroom Maintenance: One Step at a Time

Cleanrooms are used to perform clean processes, so it’s counterintuitive to think of maintenance and repair activities inside a controlled environment. Yet, they are very necessary and performed quite often. Protocol for crews working inside a cleanroom is different than the typical office space: personnel must gown and adhere to strict clean processes, just like lab technicians. The equipment crews bring into the cleanroom must also be compatible with the required ISO rating. Slow, careful movements and meticulous control over dust and other contaminants are critical to prevent complete shut-down and time-consuming recertification of the room.

How to Automatically Control Vacuum in Test Chambers

Vacuum Overview

“Vacuum” means the complete absence of matter. In order to create vacuum conditions, pressure within a given space must be lower than the surrounding environment. The quality of the vacuum is dependent upon several factors, including the number of particles within a given space. The inertia of moving particles exerts pressure, so fewer particles means lower pressure. Scientists have given up on the idea that a perfect vacuum is even possible; space is the most ideal vacuum we know of, but hydrogen atoms, energy waves and other moving particles are still present.

BioSafe® Cleanroom Ladders are Steel Workhorses

Seems like a cleanroom is no place for a ladder: a dirty, dusty, paint-smeared structure used by the contractor who does the termite repair on your house. But in fact, cleanrooms are perfectly-suited to ladders, if they are Terra’s BioSafe brand. Cleanroom and lab ladders are used to access out-of-reach filters, lighting, or equipment. For example, taking particle measurements and airflow readings below the filter face in preparation for an ISO inspection may require a ladder. And what about changing light bulbs and making small repairs? Terra’s shelf platform can be attached to ladders, providing a convenient surface for tools and small instruments.

Ladder_foldingBioSafe folding cleanroom ladders have a number of unique features that make them ideal for aseptic environments.

Meet Your Cleanliness Goals with Air Showers

Cleanroom entrances present a significant potential for contaminant infiltration, so they must be managed with this in mind.  Air showers are one way to minimize piggy-backing contaminants. They are enclosed chambers that use strong bursts of air to dislodge particulates from people or transport carts entering or exiting the room. Room entrances, and pass-throughs that incorporate an air shower, serve as a safeguard between critical and non-critical areas. Personnel are the greatest source of contamination in a cleanroom, so most of the methods of contamination reduction, including air showers, were developed to accommodate humans. Air showers range in size and construction, depending on the application, and are utilized by a diverse range of industries. So, how do air showers work?  Find out below!

How are UV Rays Beneficial to Aseptic Environments?

The sun naturally “cleanses” the earth’s surface with ultraviolet energy. Due to conditions like sun burns and skin cancer, we are most familiar with UVA and UVB rays, but there is actually a third classification of ultraviolet energy called UVC. These rays contain the highest energy, making them the most dangerous type of ultraviolet light. Fortunately, Earth’s atmosphere acts as a protective layer and UVC energy does not penetrate our ozone layer. These harmful rays, however, are industrially produced as a beneficial source of UVGI (ultraviolet germicidal irradiation). Keep reading to find out why.

How Do LED Lights Save Money?

Light-emitting diodes, more commonly referred to as LEDs, are semiconductors that emit light when an electrical current is applied to the component. Even though LEDs have been around since the early ‘60s, it is only in recent years that white LED bulbs have become more commonly used as a substitute for other industrial and household lighting systems. Their rising popularity is due, in part, to the positive impact they have on energy-efficiency.  Find out how LED lights are saving the planet, one lumen at a time.
