Chapter 3: Getting Started manufacturers of exhaust filters appropriate for use with radio-chemicals. The HEPA filter assembly can be used to remove most particulate forms of radiochemicals being used today. The activated carbon filter is used in the removal of gaseous form radiochemicals and can be used in conjunction with the HEPA filter, depending on the materials being used inside the fume hood.
Chapter 3: Getting Started ! WARNING: The building electrical supply system for Protector Radioisotope Hoods should include overload protection. A switch or circuit breaker should be in close proximity to the equipment and within easy reach of the operator. The switch or circuit breaker is to be marked as the disconnecting device for the equipment. Consult the NEC-2002 for proper installation.
Chapter 3: Getting Started All wiring for the fume hood SHOULD be performed by a licensed electrician and conform to all local codes. In most cases, the hood will require the use of shielded conduit to protect the wiring into the hood. The grounding connection shall not be made to the terminal box cover. The fluorescent light has been mounted outside the top liner panel and is sealed from vapors inside the hood structure.
Chapter 3: Getting Started Should access to the hood plumbing fixture bodies be required, remove the service access plate on the hood front corner posts by loosening their individual screws. (See item 11 Figure A-1, page 50 and page 51). The valve body will now be fully exposed for any service work that may be necessary.
Chapter 3: Getting Started Your Protector Radioisotope Fume Hood has been tested at the factory per ASHRAE 110-1995. All hoods achieve an “as manufactured rating” of less than 0.10 part per million (ppm) at 4 liters per minute (lpm); AM <0.10 (Consult Labconco for individual fume hood ratings.) For “field use” ASHRAE testing contact the Labconco Ventilation Ventures Team or Customer Service for the name of a certified on-site contractor.
CHAPTER 4 PERFORMANCE FEATURES AND SAFETY PRECAUTIONS Performance Features: The Protector Radioisotope Laboratory Hood has been engineered to provide you the maximum in work area and personal safety. The by-pass air configuration on the Radioisotope Fume Hood is totally dependent on air being supplied to the hood from its surrounding environment for proper operation. The hood itself is designed to handle radiochemical operations of all types. The hood liner should be decontaminated manually by the operator.
Chapter 4: Performance Features and Safety Precautions Even though the stainless steel seams are smooth to the touch, there are microscopic voids within the surface in which radioactive particles can lodge and are not easily removed by the above mentioned surface decontamination procedures. Abrasion decontamination, which consists of sanding and/or scouring may be required to dislodge these particles from your hood liner.
Chapter 4: Performance Features and Safety Precautions 1. Unique sash provides maximum visibility of 32.15" high while conserving energy by limiting sash travel to 28". Vertical-rising sash may be raised from a closed to 28" operating height. Exhaust volume and blower sizing is based on the 28" height. Optional sash stops are available to limit sash height and reduce energy usage. 2. By-pass airflow design ensures relatively stable face velocities. 3.
Chapter 4: Performance Features and Safety Precautions wired to hood single point junction box. Additional electrical receptacles are available as factory or field installed. 13. Type 304 stainless steel interior liner is onepiece stainless, non-reactive type 304 stainless steel with coved interior corners and integral work surface bottom. 14.

Chapter 4: Performance Features and Safety Precautions Safety Precautions ! ) Although the laboratory hood has been engineered to maintain optimum operator safety, caution should always be used while working in the hood. Prior to using the hood, check to make sure that the exhaust blower is operating and that air is entering the hood at its specified face velocity. USE GOOD HOUSEKEEPING IN THE HOOD AT ALL TIMES. CLEAN UP SPILLS IMMEDIATELY WITH A MILD DETERGENT.
Chapter 4: Performance Features and Safety Precautions ! Blocking the bottom of the baffle at rear of hood will change the airflow pattern in the hood causing turbulence and possible leakage at the face of the hood. (Don’t store containers or supplies against baffles, as this will affect airflow through the hood.) Never place your head inside hood. Keep hands out of hood as much as possible. Always work as far back in hood as possible.
Chapter 4: Performance Features and Safety Precautions MAY DRAW FUMES OUT OF THE HOOD. ! ! The use of heat generating equipment in this hood without the exhaust system operating properly can cause damage to the hood. The Protector Radioisotope Laboratory Hood should be certified by a qualified certification technician and safety officer before it is initially used. The hood should be re-certified whenever it is relocated, serviced or at least annually thereafter.
CHAPTER 5 USING YOUR PROTECTOR RADIOISOTOPE FUME HOOD Operating the VerticalRising Sash S Because of the Protector Radioisotope Hood’s counterbalanced sash mechanism, it will take only a few pounds of force to move the sash up or down, and you can operate the sash smoothly with one or two hands positioned along the handle. The vertical-rising sash may be raised to a maximum 28" operating height.
Chapter 5: Using Your Protector Radioisotope Fume Hood A Operating the A-Style Combination Sash Optional hood models have additional energy saving sashes called A-style combination sashes in place of vertical-rising sashes. These combination sashes allow the operator to use the hood with sashes either half open horizontally or vertically to conserve energy. The horizontal sashes are used in normal operating mode.
Chapter 5: Using Your Protector Radioisotope Fume Hood Working in your Protector Radioisotope Fume Hood Planning • Thoroughly understand procedures and equipment required before beginning work. • Arrange for minimal disruptions, such as room traffic or entry into the room while the hood is in use. Start-up • Turn on fluorescent light and hood blower. • Slowly raise the sash. • Check the baffle air slots for obstructions. • Allow the hood to operate unobstructed for 5 minutes.
Chapter 5: Using Your Protector Radioisotope Fume Hood Final Purging • Upon completion of work, the hood should be allowed to operate for two to three minutes undisturbed, to purge airborne contaminants from the work area before shutting down blower. Unloading Materials and Equipment • Objects in contact with contaminated material should be surface decontaminated before removal from the hood. • All open trays or containers should be covered before being removed from the hood.
