50 JULY 2018 COATINGSPROMAG.COM including an EnTech Industries 20,000-cfm (566.3 m³/min.) dust collector, a Schmidt 75 ft.³ (2.1 m³) blast pot, a 1600-cfm (45.3 m³/min.) diesel compressor rented from Sunbelt Rentals, and a 40-foot (12.2 m) surplus shipping container to hold dry goods. Enerfab PC&L staged their portable gear in a dedicated room inside the brewery. To reach the six tanks on each of the building's four floors, the crew rigged compressed air and vacuum hoses by snaking them up, into, and throughout the building. Prior to abrasive blasting the first tank, Enerfab PC&L Safety Officer Calvin Clark checked that proper abrasive blasting worker protections were in place: e confined space permit was in hand. Manway monitors were assigned. Nova air-supplied blast hoods were properly fitted and the Marco Safety/Air Systems International breather box calibrated. American Lock Co. LOTOs (lockout/tag out locks) were in place to prevent brewery workers, maintenance personnel, or other trades from inadvertently opening valves that could send pressurized liquids or gas into areas thought secured. And full-body harnesses were worn when inside the tank. Blast specifications called for NACE No. 2/Society for Protective Coatings (SSPC) Surface Preparation (SP) 10: Near-W hite Metal Blast to a 4 mil (101.6 microns) average anchor profile. e crew used 12-40 coal slag provided by BlastOne to accomplish that profile. e blast crew included up to 20 workers from Enerfab as well as local labor. e teams would be working 10-hour shifts: two teams, two shifts per day. Each blast crew comprised two blasters inside the tank, a manway watcher, a blast-pot tender in the laydown yard, a general helper, site manager, safety manager, and project manager. Most of the time, two full crews worked two tanks at a time. The tanks were on four floors of the brewery. In the cellar, ambient temperatures reached an average of 38 °F (3.3 °C), which meant the tanks had to be preheated to 58–62 °F (14.4–16.7 °C).
