    Sixty-two billion dollars: That’s how much U.S. companies pay each year to cover expenses associated with workplace injuries, according to the Liberty Mutual Workplace Safety Index.It’s no secret a strong workplace safety program is critical for protecting a business’s bottom line and its image as a safe-minded, healthy place to work. Occupational safety and health programs reduce expenses related to medical care, paid time off, litigation and disaster mitigation.more...

    Corrosion can have devastating effects on the integrity of structures and components. Corrosion, if not accounted for, can leave even the best designs useless by compromising the mechanical and chemical properties of many different materials. With proper consideration, however, corrosion can be limited and even prevented almost entirely. There are many different ways that the risk of corrosion can be reduced. This article highlights several of these key areas.Read more about crucialmore...

    In the case of insulation systems, the phrase out of sight, out of mind, often applies. Most commercial insulation work and many industrial insulation systems are hard to access or are hidden in walls, ceiling areas, or spaces that are seldom seen. These rarely seen insulation systems are designed to perform quietly for many years with little maintenance, so they are often left uninspected until a major problem occurs. For most applications operating at above-ambient temperatures (especiallymore...

    We recently took some time with John Newland, President of SPIDA (the Spiral Duct Manufacturers Assocation), to learn more about the association and the benefits it offers to contractors, engineers, and manufacturers alike. Read more about what John had to say about the state of the industry, trends he sees coming our way, and the benefits of SPIDA. Can you give us a brief introduction to who you are and your experience in the industry?more...

    When Giffin Sheet Metals Ltd. needed a large quantity of aluminized steel for an automotive project in Alliston, Ontario, the Toronto contractor reached out to a U.S. supplier in southeastern Michigan.Aluminized steel is harder to come by in Canada and the company required several hundred thousand pounds. It was a transaction the 70-year-old company had done many times before, and with the 24-year-old North American Free Trade Agreement, such cross-border purchases were virtually hassle-free.more...

    Last week, we hosted CUI Test Results: Understanding the Corrosive Mechanism, a live webinar detailing the latest test results from the most recent long-term corrosion under insulation (CUI) testing. Our webinar covered the various types of corrosion, the science behind the thermodynamics of corrosion, and the latest findings from long-term corrosion research on Thermo-1200™ calcium silicate, and Sproule WR-1200® expanded perlite, and a silica aerogel blanket specimen.more...

    Galvanic corrosion (also called bimetallic corrosion) is a deteriorative electrochemical process that occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte. This type of corrosion is characterized by the accelerated corrosion of one metal, while the other remains mostly unaffected. In other words, one metal becomes the anode and corrodes preferentially, thus sacrificing itself while protecting the other metal, the cathode.more...

    When it comes to corrosion under insulation (CUI), I tend to call it a "minefield," and for more than one reason. It’s not only a hidden phenomenon, but it's also one that can really come back to bite companies who don’t invest in a good CUI mitigation strategy, because sooner or later, those companies are going to get their names in the papers due to unwanted accidents, production loss and environmental damages. more...
