How to Install a New HEPA Filter with the Bag-In/Bag-Out Procedure for XPert Filtered Balance Systems and Stations

The XPert enclosures include a true bag-in/bag-out filter disposal system for safely removing the HEPA filter and protect the worker from toxic powders and particulates. See Figures 6-1 for the Bag- In/Bag-Out Procedure. For your safety, wear appropriate personal protective equipment during the change of HEPA filters. If working with biohazardous materials, use the decontamination procedure outlined in Chapter 6. (Consult your Safety Officer before performing filter changes).

1.With the enclosure OFF, remove the front panel secured by two screws on top of the enclosure.

2.Remove the bungee cords and retaining strap on the bag and extend it out. The retaining strap provides an extra level of safety even though the enclosure is under negative pressure when the blower is on.

3.Loosen the two filter clamp bolts with a 9/16" socket securing the HEPA filter. See Figure 4-1 and 4-2.

4.Place both arms in the rear gloves of the bag, and carefully draw the HEPA filter out of the enclosure. Rest the HEPA filter on the floor, table or cart. Remove arms from bag gloves.

5.Create two seals between the enclosure bag access port and the old HEPA filter. Seals can be heat sealed or sealed with tie wraps. Cut off the bag between the two seals and leave the bag stub on the access port to the enclosure.

6.Place the new HEPA filter in the new bag. Then place the new bag and new HEPA filter over the old bag stub and onto the enclosure access port.

7.Carefully remove the old bag stub using the single glove near the access port. Reattach the retaining strap on the perimeter of the new bag at the enclosure access port.

Draw the old bag stub into the single glove and turn the glove inside out. Double seal this glove and cut off the glove with the contaminated bag stub inside.

8.Carefully install the new HEPA filter and uniformly tighten the two filter clamp bolts until the HEPA filter gasket is compressed 50%.
