42 NOVEMBER 2015 COATINGSPROMAG.COM Sherwin-Williams Pro Industrial Urethane A lkyd Enamel. For these coatings, they used a Graco Airless Sprayer Model Ultra Max 1095 and a Titan Line Lazer Model 8950. Te crew applied the Kem Bond primer in one coat at approximately fve mils (127.0 microns) thick. Tey put down the Pro Industrial Urethane A lkyd Enamel in two coats with a total thickness of approximately seven mils (177.8 microns). Lastly, the crew put down parking lot striping. For this job, they applied Sherwin-Williams ProPark in two coats at a total thickness of approximately 15 mils (381.0 microns). T he crew wore hard-toed boots at all times, as well as ear, eye, hand, leg, head, and arm protection. T hey wore 3M respi- rator masks while spray ing, and they used hard hats and body coveralls. T hey also put on Kevlar sleeves for arm protection. Safety and Security Part of the challenge of the job was that it had so many diferent aspects to it, Miller said. Each surface that needed coating had to be treated diferently. "Tis was an odd project, because it was not one specifc item," he said. "Tere were so many diferent items we did." Another challenge was rooted in the fact that the job took place in the Midwest — and in the summer no less. Tat meant there was moisture to deal with in the morning, Miller said. "Te relative humidity level was pretty high, so we had to wait for that to burn of," he said. Ten there was an unexpected weather challenge, one that almost put the entire crew in danger. "One day, as we were packing up, one guy yells, 'Tornado!'" Miller recalled. "We said, 'Yeah, right,' but then we looked, and there was a tornado!" A regular day on the job quickly became something more like the plot to an action movie. Te crew sprang into action, stopping their work and quickly escaping to a tornado shelter that was on site at the power plant. "It was a 15-foot by 15-foot [4.6 m x 4.6 m] concrete hut," Miller said. From the shelter, they could see the tornado in action. " We looked over, and there was literally a tornado," Miller said. "One cow's life was taken — that's a true stor y. It hit a farmstead, and a barn was destroyed, and a cow was killed, but it receded just before reaching the plant. It was pretty intense." Te tornado was about one mile (1.6 km) away, and luckily it never came closer. "We could defnitely see it, and we took a cell phone picture of it," Miller said. "We weren't in immediate danger, but my heart was racing because that's not something you see every day. Tankfully, there were no injuries, but the crew has a story of a lifetime." Te crew also had to stop work for rain and thunderstorms. "Lightning was an issue because we're around metal and sometimes up on a lift, so we had to shut down," Miller said of the work during storms. Te Genie Telescopic S-65 boom lifts also required extra safety precautions because of the overhead power lines, Miller said. "We don't want to get anywhere near them for obvious reasons," he explained. "We just took everything really slow. You have to go very slow and have a guy watching the lift Surface prep on the project centered on using an angle grinder with an extra coarse abrasive wire wheel on the steel and galvanized metal to prepare it for the coatings. The entire project took two months to complete. On tanks and pipelines, the system included a primer at ~10 mils (254.0 microns) and two coats of polyurethane for a total of ~8 mils (203.2 microns). The crew worked part of the project on Genie Telescopic S-65 boom lifts, which took place over the 10-acre (40,468.6 m²) power plant. That required extra safety precautions because of the overhead power lines. Power Plant
