Designing Your Food Microbiology Cleanroom

Designing Your Food Microbiology Cleanroom

Food microbiology labs are a specific type of cleanroom that have a variety of special considerations due to the sensitive nature of the work and its importance. Not only do they need dedicated laboratory space for testing, but the controlled environment of a cleanroom is also critical. Here are some things to consider when designing a cleanroom for food microbiology applications.

Location

Food microbiology cleanrooms should be located conveniently to the production area from which samples are being tested; however, it should be away from main transportation arteries, noisy areas, boilers, and other heavy equipment.

Setup

Depending on your company’s production needs or your specific lab’s application, your food microbiology cleanroom will likely include a chemical laboratory, bacteria laboratory, and office spaces. These areas will likely require multiple rooms. The bacteria lab will probably require a sterile room, examination and operation rooms, and media production studios. Biological testing should always and necessarily be separated from other cleanroom operations. The chemical lab may require a chemical analysis room as well as an instrument room. The offices will need to be accessible to lab personnel as well as other employees, and will likely require a different level of access and control than the rest of the cleanroom space, meaning separation from other cleanroom areas.

ISO Classification

Generally speaking, food manufacturing and food microbiology cleanrooms must meet ISO Class 5 or 6 (Fed-Std 209E Class 100 or 1,000). This means that recommended air changes per hour are between 150 and 600, with 25 to 70 percent ceiling coverage. (For more information on the maximum number of particles in air allowed per cubic meter of each particle size, check out our guide to cleanroom classifications & standards.)

Most Common Cleanroom Design Problems

Most Common Cleanroom Design Problems

Cleanrooms present a lot of unique challenges in terms of design because they have very specific requirements they have to meet. If you’re meeting your desired ISO standard, you might feel like your design is good enough, but the truth is that there are a lot of common issues that companies face when designing cleanrooms. Here are some of the most common cleanroom design problems we see:

Inefficient placement

One of the biggest issues with cleanroom design is inefficiency. If your design doesn’t support your processes, it’s going to cause problems. Consider the various tasks and processes that go on in your cleanroom. Is someone always getting in someone else’s way because of where there workstations or supplies are located? Are there too many processes sharing one sink, causing a bottleneck? Are there drawers or cabinets that you can’t fully open because they’re too close to a wall or door? All of those problems can cause major inefficiency and can be avoided with good design.

Maze-like walkways

The whole point of a maze is inefficiency, it takes a long time to get through a relatively short distance because you have to twist and turn and wind around obstacles. But your cleanroom shouldn’t be a labyrinth. If employees have to walk through narrow paths, wind around oddly placed workstations, or bump into each other constantly to get to the door, their workstations, the sink, or the fire extinguisher, you will have massive safety problems on your hands, not to mention a lot of wasted time and motion on the part of the cleanroom techs.

Poor ventilation

Good ventilation is necessary for any space to be comfortable, but it’s especially crucial in a cleanroom, where you’re trying to maintain a controlled environment with limited particles and contaminants. Additionally, in cleanrooms where hazardous materials are used, good ventilation is a necessary safety concern to ensure the well-being of workers.

Unable to maintain temperature

No one wants to work in a room that’s too hot and stuffy or freezing cold, so for the same of employees comfort and morale, a cleanroom that is a comfortable temperature matters. It’s vital too that your cleanroom can maintain its desired temperature to protect the products, materials, and chemicals stored in it, as they can be sensitive to temperature, and to prevent the growth of mold and bacteria that can compromise the cleanroom environment. This could be a problem with your HVAC, thermostat, or insulation, so be sure to select those things wisely and perform regular maintenance checks.

Good design is the first step to having a well-functioning cleanroom. If you recognize some of the issues we mentioned in your current cleanroom, it’s probably time for a redesign. There are a few things you can do in the meantime to work with the layout you have and increase efficiency, such as rearranging movable cleanroom furniture, moving processes that don’t require a controlled environment to a new area, or simply cleaning out any tools, materials, or storage that is no longer necessary.

Choosing the Right Cleanroom Design and Installation Company

Choosing the Right Cleanroom Design and Installation Company

For facilities requiring a clean environment, the cleanroom itself is a crucial component. As a general contractor or builder, you know that finding the right company to design/build and service, your cleanroom is a critical part of your projects success. How do you choose the right cleanroom design and installation company? Here are some qualities a good cleanroom design company should have:

Good communication—quick response times

Communication is essential in any construction project, and it’s vital for subcontracted work. The cleanroom design company that you chose should give respond quickly with a budgetary quote, and be able to answer any technical questions you may have in the design/build portion of your project. Once the project is underway supply you with weekly project updates, keeping your timeline in check.

Fast lead times and ability to meet deadlines

You don’t have months and months to get this cleanroom constructed—you need it done quickly and efficiently, within your timeframe. You have deadlines that you have to meet, and the cleanroom designer should understand and respect that. Given a reasonable amount of time and all the necessary information to complete the cleanroom project, a good cleanroom design firm should be able to make quick turnaround times and keep the cleanroom, and therefore the rest of your project, on schedule.

Customization capabilities

Good cleanroom designers will work with you to create the right cleanroom for the client, and this may include custom requests. Good designers aren’t inflexible—they won’t just provide a boilerplate, cookie-cutter, one-size-fits-all cleanroom, because the needs of each client are unique, based upon cleanroom application and other circumstances. The cleanroom design firm you choose should be willing and able to design custom elements such as casework, cleanroom benches, and tables, to fit the client’s specific needs.

Ability to stay on budget   

Cleanrooms can be an enormous cost for your client, and as such, the budget must be respected. If a cleanroom designer can’t stick to the agreed-upon budget, the project can’t succeed, and problems will arise for all parties, the cleanroom design company, you, and the client. Good cleanroom designers will be able to provide a workable cleanroom design within budget constraints.

Selecting the best company for your cleanroom design and installation project is the first and most essential step in providing your client with the cleanroom their company needs. Finding a cleanroom design company with good communication practices, quick turnaround times, the ability to customize, and budget-consciousness will ensure that your cleanroom design is a success.

What to Think About When Choosing Cleanroom Furniture

What to Think About When Choosing Cleanroom Furniture

Designing a cleanroom comes with a huge set of unique challenges: controlling the temperature, air quality, static, water purity, etc. What can get overlooked during a cleanroom design is the fixtures and furniture, which are extremely important to the efficiency and ergonomics of your cleanroom space. Here are the questions you should ask when selecting casework and furniture for your cleanroom:

What types of chemicals and materials will be used?

Depending on the substances that you’ll be using in the cleanroom, you may need to ensure that you select work surfaces that are chemical resistant, heat resistant, stain resistant, or non-conductive. This will also inform whether you’ll need fume hoods or chemical or hazardous material storage.

What processes will be performed?

This determines the number and types of workstations you’ll need, as well as their layout. If your cleanroom is used for clean storage of sensitive materials, you’ll probably need cabinetry, shelving, and casework, but if your cleanroom is used for quality control testing, you’ll likely need workstations with storage, sinks, electricity and more.

How often will things change?

If you need flexibility for when processes change, or your cleanroom houses multiple different operations. You may need to consider the flexibility and changeability of the furniture you choose. This can be accomplished with adjustable height tables, workstations or casework on wheels, or adjustable cabinetry that allows you to reconfigure the drawer and cabinet locations.

How many chairs do you actually need?

This seems trivial, but can be a major issue for efficiency. Too many chairs mean there’s always one in the way, and that space is wasted. Too few seats leave your employees playing musical chairs all day. Consider ergonomics with chairs and ensure they are the right height and comfort level for their application. Stools may be the most appropriate choice for cleanrooms where technicians sit for short periods of time at counters; however, if your employees are sitting at workstations for long periods of time for certain operations, they’ll need more comfortable seating.

How much storage is needed?

No matter your cleanroom application, you’ll need storage of some kind, whether for materials, packaging, or the tools and equipment used in your processes. Ensuring that you have the right kind of storage for these items is also important. While shelving may work for bulk storage of boxed items, you’ll need cabinets for chemical storage or racks and drawers for tools.

How much space do I have?

If you’re working with limited space, it’s critical that you maximize that space. Too much furniture can impede movement and therefore,  the efficiency of your cleanroom operations. Consider how spaces can be made flexible for multiple operations or how the furniture can be best laid out for process flow, as well as the movement of people within that space.

 

When designing or upgrading a cleanroom, don’t forget the furniture. Using your cleanroom space inefficiently or having the wrong furniture or materials, or simply not having enough storage or seats can make a cleanroom into a chaotic mess. Ask yourself these questions when selecting cleanroom furniture to ensure a well-designed cleanroom for your application.

New Trends in Cleanroom Design

New Trends in Cleanroom Design

Now that the holidays are over and the new year has begun, you might finally be getting around to implementing a new cleanroom in your facility. If you’re designing a new cleanroom or updating your current one, here are the latest trends in cleanroom design that you should consider as you design your cleanroom space.

 

Sustainability

Sustainability is an important consideration for all of us, including corporations. Because cleanrooms use so much energy to maintain the desired environmental conditions, engaging in sustainable practices when possible is crucial. Not only do these sustainability efforts support the natural environment, they are also energy efficient, which can help you save on energy costs. Using energy efficient equipment and energy efficient LED lighting can aid in sustainability efforts, as can a modular cleanroom. Modular cleanrooms can be altered and right-sized as the needs of your company change, while reusing the modular components, and require less material than traditional construction. Additionally, modular cleanrooms can make use of the currently existing HVAC and ventilation systems in your space, rather than requiring separate systems.

 

Transparency

Now, more than ever, we’re aware of the value of transparency from leaders and companies. When it comes to your cleanroom, the primary concern will always be the integrity of the controlled environment within, and it may also be important to maintain privacy for the safety of intellectual property, but cleanrooms can benefit from some openness and visibility. Using transparent partitions in the place of opaque walls can provide some benefits, the biggest of which being that lab processes can be observed, whether by compliance regulators or supervisors within your organization, without disturbing cleanroom processes or the environment within.

 

Flexibility

Many organizations are resisting the use of specific dedicated spaces for certain tasks or operations, instead opting for more shared spaces and flexibility in order to reduce costs and under-utilized space. This means incorporating fixtures and furniture, such as lab benches and workstations, into your cleanroom that can accommodate a variety of tasks or processes, as well as modular cleanrooms that can be easily expanded, contracted, or reconfigured to maximize use of space.

 

As you’re working on your cleanroom design or redesign, consider the needs of your company and your cleanroom, as well as how the cleanroom can continue to meet those needs over time, with organizational and regulatory changes. Incorporating sustainability, transparency, and flexibility into your cleanroom design can make your cleanroom efficient and future-proof, not matter the changes to come.

Benefits of Cleanroom Pass-Through Chambers

Pass-through chambers are a commonly used cleanroom term, and they’re also an ideal addition to just about any cleanroom. They’re easy to install, they don’t draw much out of your budget, and they hold tons of benefits for the operation of your cleanroom. While there are all types of pass-through chambers, from basic transaction windows to industrial roll-up door pass-throughs, most cleanroom pass-throughs fall into the dual-door category. Because the removal of contaminants is any cleanroom’s top priority, most cleanroom pass-through chambers have two doors, one on the outside and one on the inside of the cleanroom. Those cleanrooms that must meet higher standards often install pass-throughs with additional features like an air shower or fire resistance, but the general construction and operation is the same.

What are the benefits of cleanroom pass-through chambers?

  • They allow your employees to transfer materials in and out of your cleanroom without contamination.
  • They make it easy for employees to pass materials into the cleanroom without having to gown. This also cuts down on the number of employees in your cleanroom at any one time.
  • They come in a variety of sizes and materials, ensuring you get the pass-through that meets the needs of your employees. Stainless steel options are corrosion-free, which extends the life of your pass-through, and helps keep your cleanroom clean.
  • Double door designs ensure cross contamination doesn’t happen. And heavy duty sealing lock features keep contaminants out of the chamber when it’s not in use.
  • Most pass-through chambers are customizable, allowing you to choose the option that best fits the needs of your cleanroom. Whether you need a fire safe option, one that’s chemical resistant, or a pass-through chamber that includes a blower with HEPA filtered air, you can choose the chamber that best suits your cleanroom needs, ensuring you benefit from a pass-through chamber, regardless of your cleanroom classification.

How do cleanroom pass-through chambers increase productivity?

The single greatest benefit of a cleanroom pass-through chamber is its ability to speed up your processes and increase employee productivity. Pass-through chambers eliminate the need for employees to properly gown to enter a cleanroom environment just to hand off a necessary item or sample. As you likely know, the gowning process can be time-consuming, and additionally, the more employees you have in a cleanroom, the greater the chance for contamination. When employees can simply place materials in the pass-through chamber, you save a great deal of time on both sides of the cleanroom. Best of all, pass-through chambers are easily installed, whether you have an existing cleanroom or you’ve just commissioned a new one.

Who uses pass-through chambers?

The benefits of pass-through chambers are clear. They boost productivity without sacrificing cleanliness. So, which cleanroom industries use pass-through chambers, and how?

Research Facilities

Because research facilities often study new and unpredictable chemicals and substances, they need pass-through chambers for safety more than for convenience. Because some chemicals can easily become volatile and cause fires, fire safe pass-throughs are commonly used in this application. These pass-through chambers can withstand fire exposure for up to 90 minutes, and their sturdy construction maintains frame shape that protects research labs from destruction. While these labs also often make use of air shower pass-throughs to decontaminate materials before they’re introduced to the lab, fire safe pass-throughs are the most common.

Medical and Pharmaceutical cleanrooms

Decontamination is the first priority of both medical and pharmaceutical cleanrooms. Because hospital laboratories often deal with highly contagious substances, it’s paramount that the environment remains sterile. In the same vein, pharmaceutical cleanrooms have to ensure there is absolutely no contamination in the manufacturing process that could alter their product. In both cases, these cleanrooms require pass-through chambers that keep samples, specimens, and other materials sterile as they’re brought into the cleanroom. These industries typically make use of a standard two door pass-through chamber that keeps outside contaminants from entering the cleanroom and ensures the materials remain sterile as they’re waiting to be brought in.

Electronic and technology manufacturing cleanrooms

Manufacturing facilities that put together the complex inner workings of technological devices like computers and smartphones require very strict cleanroom environments that filter out even the smallest particles of dust and other contaminants. Just one tiny particle settling on a single piece in the manufacturing environment could render a future hard drive useless. Many electronic and technology manufacturing cleanrooms opt for highly monitored pass-through windows in order to maintain the sterility necessary to produce quality electronic products while maintaining a high level of productivity.

 

Pass-through chambers are a highly useful component of any cleanroom. They help you ensure that you keep your processes moving, while maintaining the high standard of cleanliness within your cleanroom.
