The BSC can provide laboratory personnel protection against harmful material that is stored in the cabinet. Alternatively, the biological safety cabinet may also provide protection for the product within the cabinet against outside harmful agents. Biological Safety Cabinets are divided into three class, with assigned biosafety levels to each class. The three classes are: Class I Biological Safety Cabinet is for environmental and personnel protection only and has biosafety levels of 1,2,3.

A: Cleanroom cleaning is a broad term that may refer to the ongoing cleaning of a cleanroom or a super-cleaning that may occur at longer intervals. Both types of cleaning may be carried out by in-house personnel or professional cleaners. The intensity and frequency of cleaning will largely depend on the activities that are being carried out in the cleanroom, the classification of the cleanroom and also whether any breaches have occurred in the contamination control procedures.
A: Cleanroom compatible means that the product is suitable for use in a cleanroom environment. It means that the product will not contaminate the cleanroom beyond the permitted levels. Everyday items which have cleanroom compatible versions are: furniture, protective clothing, gloves, cloths, mops, pens, paper and telephones.
A: Cleanroom computers are computers that have been specifically designed and manufactured for use in cleanrooms. Cleanroom computers do not emit contaminants or pollutants into the cleanroom environment. They are also manufactured in such a way that they do not harbour particles and so they are not a risk to the sterile environment in which they operate.

The method of entry and the procedures that must be followed are often cleanroom specific and are dependent on the level of contamination control that is to be maintained in the cleanroom. It is common to find that the change area is divided into three zones, or areas. These zones are pre-change zone, changing zone, and cleanroom entrance. Personnel move through the zones carrying out the changing procedure as outlined by the individual cleanroom protocol.

A: To ensure cleanroom safety, personnel should wear the appropriate personal protective equipment (PPE) including eye protection, face masks and gloves where appropriate. Workers should be familiar with the cleanroom protocols and layout of the facility. Personnel must not use equipment, materials, or processes that they are unfamiliar with, instead, they must get the proper training first. Locate and understand the proper operation of safety equipment including fire extinguishers, safety showers, eye wash stations, and emergency shut off and bypass switches. Know the facility emergency signals, alarms, and evacuation routes and procedures. Know and follow compressed gas cylinder safety protocols; ensure that they are familiar with hazardous gas monitoring equipment and the associated alarms.

They go by a variety of names including softwall cleanrooms, soft wall cleanrooms, modular cleanrooms, clean isolators and portable softwall cleanrooms. Portable cleanrooms can be made from a variety of materials and can be tailored to meet specific requirements.
A: A mobile cleanroom is pre-fabricated, pre-tested and certified. They are often built inside cargo container and can be moved to the location where it is needed. Mobile cleanrooms are stand-alone enclosures containing their own mechanical system for basic comfort cooling or for precise temperature and humidity control, emergency power, lighting, water, ancillary support systems and a filtration system to meet the specified cleanliness levels, including HEPA or ULPA filtration for applications requiring a certified cleanroom environment.
A: A laboratory device which flows filtered air onto a specially enclosed work surface. Typically, eye banking uses vertical flow hoods, which projects clean filtered air down onto the work surface. This prevents particulate and microbial contamination, while protecting the technician from the potential exposure to infectious material being handled.
A: HEPA (high efficiency particulate air) filters are a type of air filter used in the cleanroom industry and other industries with clean air requirement. HEPA filters are created from a  mesh of fibers that are composed randomly, and as air is passed through it, it acts like a sieve, removing particles from the air. The effectiveness of the HEPA filter depends on several attributes: thickness, fiber density and diameter. HEPA filters can remove 99.97% of the 0.3 µm particles, with the assumption that these size of particles will be unable to find a path through the thick mesh of fiber and will become trapped.
A: Individual cleanrooms will have their own gowning up guidelines and procedures. The following is an example of a gowning up procedure: Gowning up should be carried out in this order: Face Mask, Safety Glasses, Hood, Coverall (bunny suit), Shoe covers/boots and finally Clean room gloves. Individual cleanroom policy should be followed when deciding what to do with the protective clothing once it has been used. This will largely depend on whether the garments are disposable or reusable. Gowning up will usually take place in the gowning room where there will be a stepover bench that spans the width of the room. The area at one side of the stepover bench is "dirty" and the other is "clean". Gowning up starts on the dirty side and as you place a cover on each shoe, move the foot over the bench and place it on the clean side. This ensures that no dirt is carried into the clean side of the gowning room.

The windows can be flush with the partition system which allows ease of cleaning and a reduced risk of contamination. The air tight, sealed frame makes the windows completely impervious to any airflow.
A: After the cleanroom has been constructed and is fully operational there are a various amount of maintenance procedures that need to be done in order to keep the cleanroom to the required standards of a cleanroom. Cleanroom Services provide these maintenance procedures and including such operations as Cleanroom Testing, Cleanroom Certification, Cleanroom Sterilization, Cleanroom Audits, Benchmarking, Training, Cleanroom Cleaning, etc.
A: To ensure cleanroom safety, personnel should wear the appropriate personal protective equipment (PPE) including eye protection, face masks and gloves where appropriate. Workers should be familiar with the cleanroom protocols and layout of the facility. Personnel must not use equipment, materials, or processes that they are unfamiliar with, instead, they must get the proper training first. Locate and understand the proper operation of safety equipment including fire extinguishers, safety showers, eye wash stations, and emergency shut off and bypass switches. Know the facility emergency signals, alarms, and evacuation routes and procedures. Know and follow compressed gas cylinder safety protocols; ensure that they are familiar with hazardous gas monitoring equipment and the associated alarms.
A: Cleanroom requirements are determined by the activities that are carried out in a cleanroom. Cleanrooms can be individually designed to meet specific cleanroom requirements set out by the design team and/or client. An example of the most important requirements to consider when building a cleanroom are as follows: capacity, class of cleanroom, temperature, humidity, lighting levels and resistance to corrosive/abrasive substances.
