6. Insert the wand from the wetting agent sprayer through the wetting agent sleeve. Using duct tape, tape the wetting agent sleeve tightly around the wand to prevent leakage.

7. One person places his hands into the long-sleeved gloves while the second directs the wetting agent spray at the work.

8. If the section of pipe is covered with a protection jacket, this is removed first, using the wire cutters to cut any bands and the tin snips to remove the jacket. It is important to fold the sharp edges in to prevent cutting the bag when it is placed in the bottom. A box may be put in the bottom of the bag when the tools are placed in, and the metal placed in the box to further protect the bag from being cut.

9. With the insulation'exposed, using the bone saw, cut the insulation at each end of the section to be removed. A bone saw is a serrated heavy-gauge wire with ring-type handles at each end. Throughout this process, wetting agent is sprayed on the cutting area to keep dust to a minimum.

10. Once the ends are cut, the section of insulation should be split from end to end using the utility knife. The cut should be made along the bottom of the pipe and the wetting agent continuously supplied. Again, care should be taken when using the knife not to puncture the bag. Some insulation may have wire to be clipped as well. Again, a box may be used as in (d)9 above to protect the bag from puncture.

11. Rinse all tools with wetting agent inside the bag and place back into punch.

12. The insulation can now be lifted off the pipe and gently placed in the bottom of the bag, while the side of the insulation adjacent to the pipe is being thoroughly wetted.

13. Using the scrub brush, rags and water, scrub and wipe down the exposed.

14. Wet the donut-shaped pieces of wettable cloth over the exposed ends of insulation remaining on the pipe.

15. Remove the wetting agent wand from the wetting agent sleeve and attache the small nozzle from the HEPA-filtered vacuum. Turn on the vacuum only briefly to collapse the bag.

16. Remove the vacuum nozzle and twist the wetting agent sleeve closed and seal with duct tape.

17. Remove all the tools and draw them out into one of the arm sleeves, twist the sleeve tightly, and seal with tape, and cut the sleeve away from the bag, cutting
