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.
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.
BioSafe folding cleanroom ladders have a number of unique features that make them ideal for aseptic environm
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!

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 does UVGI work?
UVGI is a technique that utilizes short-wavelength ultraviolet light to kill microorganisms. Since UVC energy is not naturally present within our planet’s atmosphere, earth-bound microorganisms, such as germs or viruses, have not evolved to naturally defend th
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.
In the United States, EISA (Energy Independence and Security Act of 2007) banned the production of incandescent bulbs in order to move towards a more energy-effi
Activated charcoal is highly porous carbon used in air filters to capture solvent fumes and organic compounds by adsorption of molecules (van der Waals forces). Unlike particle filters, which rely on micro-pores to capture solid contaminants suspended in air, Terra’s coconut-shell based charcoal filters remove a wide range of chemical fumes and odors common to laboratories and manufacturing environments. To understand chemical vapor filtration, let’s first focus on what having a carbon-based filter means.
Did you know…
Traditional charcoal is a common commodity, found in everyday-homes (cooking barbecues, vacuum cleaners, etc.). But did you know your water filter may contain activated carbon? Drinking water is often filtered through activated charcoal to remove certain toxins, and
Terra Universal specifically designs environments and furnishings to meet the needs of aseptic operations that must conform to strict FDA, cGMP and other standards involving potential microbial contamination. Bio-pharmaceutical applications require this level of sterile environment for successful disease research and drug development. We call this special line of products BioSafe. What makes Terra’s BioSafe solutions clean enough for sterile operations? The answer hinges on high-grade materials and easy-clean designs.
Smooth stainless steel (SS) construction (304 or 316 grade) is standard for many BioSafe cleanrooms and other enclosures. These products also incorporate all-stainless steel hardware. Chrome-plated fixtures, unlike stainless steel, are subject to flaking and deterioration from metal-on-metal action, and can eventually rust if exposed
Electronic hand dryers are all the hype when it comes to hand-drying cleanliness. Did you know, though, that they’ve been proven to be less efficient and hygienic than paper towels, according to a 2012 Mayo Clinic study? Then, why would anyone willingly choose to use them? It’s true certain hand dryers can leave your skin dirtier than before you began; however, the researchers only examined commonly sold models of hand dryers. ULPA-filtered (Ultra-Low Penetration Air) hand dryers, such as Terra Universal’s PureDry Cleanroom Hand and Glove Dryers, would drastically change the outcome of the evaluation.
So what should you look for in a hand dryer?
Most models of hand dryers found in public restrooms, even cleanroom gowning rooms
For decades, environmental test chambers have been used to study products with countless applications in fields such as aerospace, artificial intelligence, automotive, electronics, solar cell, medical, industrial and consumer research. In these industries, the sample or material to be tested must be exposed to defined variations of environmental factors to study the effects, or even as preparation for future studies.
The conditions an environmental test chamber is able to replicate are: temperature set-point (or variations), moisture in the form of relative humidity or rain, electromagnetic radiation, vibration, weathering, salt spraying, sunlight exposure/UV degradation, and vacuum. The type of testing involved will determine the chamber type; chambers come in a variety of sizes and are designed with different functionality and options.
An Ionizing Blow-Off Gun is a hand-held device used to eliminate static, dust, and contaminants from a variety of surfaces and parts. It is shaped similarly to a gun and includes a trigger. The emitter is made from titanium that resists corrosion, ensuring the blow-off gun will last. Guns can actually operate for several years if used with a filtered gas supply. Replacing the tip can be done in a matter of seconds and you do not have to dissemble the gun to do it. There is also an optional inline capsule filter which ensures that the incoming feed gas is pure.
How an Ionizing Blow-Off Gun is Used
An Ionizing Blow-Off Gun is used to remove contaminants and static charges from surfaces and parts, which reduces the chance of damage from
