From Jeremi Day of Allphaz Inspection Services on May 16, 2012:
Use a 45° or 90° nozzle.

From PARVEZ SHAIKH of SANDVIK ASIA PVT. LTD. on June 15, 2012:
     I do agree to the use of angular nozzle for blasting.  Also, if possible, use an exhaust duct to remove the dust generated so that the blaster has good visibility.

From chris atkins of mott macdonald on June 26, 2012:
To be honest, I'd go for not using something that needs a high degree of surface prep. We've used vapour phase inhibitors before, and you can get some decent surface-tolerant coatings. Basically, design out the need for it. 

From Tony Johnson of Self on June 5, 2012:
     I agree with the previous guys about using an angle nozzle or a stubby. Have good lighting to see. Also, trigger your pot man to turn your sand way down so you're not blinding yourself with dust and you will also be able to burn your creases clean if you're wanting a SP-10.

From Michael Beitzel of Modjeski & Masters inc on June 20, 2012:
     The most important is complete access. A suitable platform under and outside the box beams is critical. In addition to angular and pencil nozzels, vacuum blasting is also helpful to provide good visibility augmented by adequate lighting. Using slurry blasting is also helpful on the interior of these box beams as rebound and visibility are improved. Also, slurry blasting is more aggressive in removing the heavier corrosion typically found in these locations.

From Richard McLaughlin of Marco Group International on May 22, 2012:
     I agree with Jeremi, adding you can also use a "banana" nozzle and set up a lance to facilitate reaching in further or out of the way places. With an angle nozzle, I also used to use a piece of duct tape attached to the hose to designate the location of the nozzle orifice, since it can be a pain sometimes to determine where the nozzle is aimed before you hit the deadman.
