8 ROOF COATINGS 2017 COATINGSPROMAG.COM such as the spray rig can be left on the ground in a staging area. In this instance, a crew member should be responsible for monitoring the rig. According to Burns, some contractors have become quite innovative in dealing with the problem. "If you're using a sprayer, you're using a pump," Burns said. "A spray rig won't [accommodate] 5-gal. [18.9 L] buckets. It comes in 55-gal. [208.2 L] drums. But what some contrac- tors will do is disconnect the spray tip and just put their hose right into our hopper. at gives them the benefit of using the same material without a crane or carrying it up." For personnel, the U.S. Occupational Safety and Health Administration (OSHA) advises contractors to perform a job hazard analysis (JHA) before starting any job to identify potential risks and create a plan to manage the risks. Because every job is different, the proper personal protective equip- ment (PPE) for contractors will vary based on the roof condi- tions, product installed, and application equipment used. In general, fall protection is often the biggest concern, partic- ularly when working near the edge of a roof. Harnesses, lanyards, and perimeter lines may be popular precaution techniques, with DBI-SALA by Capital Safety — part of 3M's fall protection division — and Honeywell 's Miller Fall Protection among the industry leaders in providing these systems. Slip resistance should also be considered, since freshly applied coatings could potentially lead to slip and fall accidents. To avoid this, contractors walking backward when applying — away from the new coating — should have other crew members watching to alert them if they are too close to an edge. Proper footwear, eye protection, and skylight covers may also be necessary on a rooftop coatings jobsite. Lawmakers are also becoming increasingly involved. As of January 2017, OSHA's long-awaited update to the walking-working surfaces rule became effective, establishing employer requirements for contractors using personal fall protection systems. OSHA estimates the standard will affect ~112 million workers at 7 million worksites. In the final rule, the term " low-slope roof " was added. According to OSHA, although these roofs are often referred to as "flat roofs," even these have some slope to allow for drainage. As such, fall protection requirements, such as guard rails, netting, and travel restraint, are specified to varying degrees, depend- ing on how close a worker is to the edge. e rule allows employers to use non-conventional fall protection practices in certain situations, such as designated areas on low-slope roofs for work that is temporary and infrequent, and fall protection plans on residential roofs when employers show that guardrail, safety net, or personal systems are not feasi- ble or create a greater hazard. e rule also specifies require- ments that employers ensure workers who use these systems and work in hazardous situations are properly trained. Possible Substrates Once safety and access issues are squared away, a contrac- tor could encounter any number of substrates. "W hen you're looking at handling a repair or restoration project, the first thing you want to establish is what you're painting on top of," said Rust-Oleum's Gibbons. "In the roofing world, there are lot of substrates that people may not be familiar with if they aren't a roofing contractor. Identifying is one of the first steps." "Residentially, you have shingles," Gibbons continued. "For those, you only use patch and repair. You don't put a coating on top of shingles. en, when you get into flat or low-slope roofs, single-ply [membrane] is probably the hottest on the market. And then people throw coatings on top. You can also see asphaltic roof surfaces, or built-up roof [BUR] Roof Coating Systems Working on roofs naturally means working at heights, which not only affects personal protective equipment (PPE) but also equipment choices. Using rollers, such as Rooftop Equipment's Titan, may be an option. As opposed to residential roofs, which may have a steep slope, many commercial roofs are considered flat or low-slope roofs, such as the one from The Garland Company shown here.
