CHAPTER 4 THEORY OF OPERATION AND SAFETY PRECAUTIONS All clean benches operate using the following principles: • • Filtration and retention of particulates by High Efficiency Particulate Air (HEPA) filter(s) Laminar airflow The major components in a clean bench are: • • • The HEPA filter The motor/blower to force air through the unit A speed control for the motor Product Service 1-800-522-7658 23
Chapter 4: Theory Of Operation And Safety Precautions HEPA Filters HEPA filters are disposable, dry-type particulate filters. The filter material or media is typically made of borosilicate microfibers that are made into a thin sheet, in a process similar to the production of paper. This sheet is folded, or pleated to increase its surface area. The pleats are held in place by aluminum diffusers or by beads of glue that add rigidity to the media pack.
Chapter 4: Theory Of Operation And Safety Precautions Figure 4-1 Laminar Airflow Laminar airflow is defined as the movement of a body of air in a single direction, with a uniform velocity. In practice, the horizontal laminar flow of air in the bench captures any aerosol generated in the work area of the bench, and directs it out of the enclosure. In order to be true laminar flow, a number of individual velocity test points (The Velocity Profile) must be +/- 20 % of the average of all the test points.
Chapter 4: Theory Of Operation And Safety Precautions Figure 4-2 Motor/Blower The motor/blower assembly pulls air through the prefilters on the top of the bench, and flows through the HEPA filter, which then flows horizontally through the work area. Speed Control ! The speed control should only be adjusted by a qualified certifier. The speed control is an electronic circuit that allows the certifier to set the motor speed by adjusting its voltage.
Chapter 4: Theory Of Operation And Safety Precautions Safety Precautions Because air from the work area is dispersed directly into the laboratory, the Purifier Clean Bench should never be used in conjunction with biohazardous material, toxins, or radionuclides. The operator and qualified safety officer(s) must carefully assess the risk associated with any operation performed in a Clean Bench. The Purifier Clean Bench should be certified by a qualified certification technician before its initial use.
Chapter 4: Theory Of Operation And Safety Precautions ! ) The surface of the HEPA filter is fragile and should not be touched. Care must be taken to avoid puncturing the HEPA filter during installation or normal operation. If you suspect that the HEPA filter has been damaged, DO NOT use the clean bench; contact a local certification agency or Labconco at 800-821-5525 for recertification information.
Chapter 4: Theory Of Operation And Safety Precautions CLEAN THE INTERIOR SURFACES OF THE CLEAN BENCH WITH MILD HOUSEHOLD DETERGENT. DO NOT USE ABRASIVE CLEANERS, BLEACH OR SOLVENTS, AS THEY MAY DAMAGE THE WORK SURFACE. Avoid direct exposure to ultraviolet radiation. NEVER work in or near the clean bench when the UV light is on. ! ) WHEN SURFACE DISINFECTING THE PURIFIER: • • • AVOID SPLASHING THE DISINFECTING SOLUTION ON SKIN OR CLOTHING. ENSURE ADEQUATE VENTILATION.

Shutdown • Turn off the fluorescent light and clean bench blower. • Turn on the optional UV light if desired. Safety and Comfort Many factors in our work environment determine whether we work efficiently and in a manner that promotes good health and safety.
Chapter 5: Using Your Clean Bench ! Don’t sit in one fixed posture all day. Feet, Knees, and Legs Make sure your feet can rest solidly and comfortably on the floor or footrest while sitting. Use an adjustable chair that allows your feet to rest firmly on the floor, or use a footrest. If you use a footrest, be sure it is wide enough to accommodate different leg positions within your comfort zone. ) ! REST YOUR FEET FIRMLY ON THE FLOOR OR A FOOTREST. Don’t dangle your feet and compress your thighs.
Chapter 5: Using Your Clean Bench Back Use your chair to fully support your body. Distribute your weight evenly and use the entire seat and backrest to support your body. If your chair has adjustable low back support, match the contours of the chair's backrest to the natural curve of your lower spine. Always make sure your lower back is well supported. Make sure it feels comfortable in the position in which you are working.
Chapter 5: Using Your Clean Bench ! Don’t rest your palms on the work surface while working. Shoulders and Elbows Adjust your chair height or clean bench height so that your shoulders are relaxed and your elbows hang comfortably at your sides. Relax Remember to relax, particularly in areas where muscle tension often builds, such as your shoulders. Eyes Working at your clean bench for long periods can be a visually demanding task and may cause your eyes to become irritated and fatigued.
Chapter 5: Using Your Clean Bench Positioning Work Materials Position work materials directly in front of you to avoid twisting your neck and torso. This makes it possible to work with your shoulders relaxed and your upper arms hanging freely at your sides. Minimizing Your Reach Arrange your frequently used materials to minimize the distance you reach for them. Hand Manipulation Notice how you use your fingers and hands while working. Avoid keeping any unnecessary tension in your thumbs and fingers.
Chapter 5: Using Your Clean Bench Taking Breaks and Varying Your Tasks As noted earlier, your furniture placement, lab equipment, and lighting are only a few of the factors that determine comfort. Your work habits are also very important. Remember the following: • • • • Take breaks. When you work at your clean bench for long periods, take short breaks at least once per hour and preferably more often. You may find that frequent, short breaks will benefit you more than fewer, longer breaks.
Chapter 5: Using Your Clean Bench Self-Check To increase your comfort and reduce potential safety risks, use this checklist to help you evaluate your work posture and habits.
Chapter 5: Using Your Clean Bench General Prevention • Do you take breaks and walk around briefly, preferably once per hour? • Do you exercise regularly? • Periodically, do you take inventory of the stress in your life and change what is within your control to change?
