On November 4, 1993, OSHA’s Lead in Construction Standard became the law of the land. Initially, (and to some extent today) the small residential contractor community reacted with complete outrage due to marketability fears, many claiming that they would simply stop working on “old houses.” Industrial contractors along with the larger residential and commercial contractors often at first ignored or complied in a lackadaisical manner with these laws, continuing to work “as it’s always been done.”
This standard specifies requirements and gives recommendations for the pre-installation surveys, design, materials, equipment, fabrication, installation, commissioning, operation, inspection and maintenance of cathodic protection (CP) systems for offshore pipelines for the petroleum, petrochemical and natural gas industries as defined in ISO 13623. It is applicable to carbon steel, stainless steel and flexible pipelines in offshore service, and to retrofits, modifications and repairs made to existing pipeline systems. Key words: Cathodic protection, impressed current, offshore pipeline, CP system design, galvanic anode, galvanic anode manufacturing, galvanic anode quality control, pipeline design for CP This nationally adopted ISO standard is not available for complimentary download by members.
Those who started in the industrial painting industry back in the 1980s may remember that third-party inspectors, hired by the owner, performed all of the inspection activities and documentation. The NACE Coating Inspection Program (CIP) had just begun in the early 80s, but those getting certified did not work for a contractor. That has changed. Now contractor quality control (QC) and owner quality assurance (QA) are much more clearly defined.
This paper examines the authors successful experiences on some simple and very complex projects where both the coatings and environmental requirements were limited to a few pages. Being made up almost entirely of SSPC/NACE and PDCA standards that described “performance criteria” as opposed to being a prescriptive or proprietary type of specification defining what was to be used, when it was to be used and how it was to be done.
The Minnesota Department of Transportation (MnDOT) with KTA-Tator, Inc. (KTA) conducted a one-day seminar on Bridge Maintenance Painting Strategy & Project Design in May 2013. One outcome of that seminar was the realization that MnDOT needed a more uniform method to rate the condition of coatings statewide during the biennial bridge safety inspections and a process to select and prioritize maintenance painting strategies. MnDOT assembled a Technical Advisory Panel to address these needs and launched a multi-objective study from October 2013 through June 2014.
The current National Ambient Air Quality Standards (40 CFR parts 50, 51, 53 and 58) for lead were published in 1978 to protect the public from the adverse health effects caused by lead. On May 20, 2008 the EPA published proposed changes to the NAAQS for lead; the final rule was published on October 15, 2008. These changes will affect the ambient air monitoring protocols required on industrial painting projects. This paper will focus on the practicalities of obtaining valid data from TSP-lead air monitors.
The following describes some equipment and practices used for cleaning and painting the variety of substrates found on commercial stores: concrete masonry units (CMU), precast and tilt-up panels, steel awnings and canopies, Exterior Insulation Finish Systems (EIFS), and polycarbonate. Many contributing factors can create either a fairly straightforward and simple process or a very complex project.
Composite coatings are a class of materials that are described as fiber-reinforced polymers (FRP) that consist of extremely strong tensile fibers saturated in a binding resin. From the original development as tank bottom lining materials designed to handle surface movement and corrosion, the applications for composite coatings have broadened and moved into the mainstream, with industry-accepted design codes written around their uses and applications
