Genoa, Italy Bridge Collapse- August 2018: The bridge was only 51 years old and the steel cables supporting the bridge failed likely due to damage from corrosion. Fall of Railway Traffic Lights- November 2014: A train traveling through England struck the railway traffic lights near an intersection. The post holding the lights fell due to corrosion and then struck by an oncoming train. Sinking of the Erika - December 1999: The Maltese taker broke into two while traveling near the coast of Britany France. Nearly 20,000 tons of oil were spilled. Multiple parts of the ship that had failed were compromised by corrosion. Bhopal, India Incident-December 1984: Corrosion caused toxic gas from a pesticide plant to leak into the atmosphere. More than 500,000 were exposed to the gas and official numbers says the tragedy caused 2,259 fatal victims. Unofficial sources say the number can be close to 8,000 fatal victms. Balcony Collapse at University of Virginia- May 1997: A balcony collapsed during the spring commencement ceremony. Rust had eaten way at the metal rods inside the balcony, which failed under the wight of the attendees. An engineering firm hired by the university said the collapse likely was caused by the failure of one of the four hangar rods that suspended the balcony.

"Corrosion has a huge economic, environmental and sustainability impact on virtually all facets of constructional materials, from highways, bridges, and buildings to oil and gas, chemical processing, desalination, nuclear, power facilities, water, and wastewater systems. In addition to causing severe environmental damage and threats to public safety, corrosion disrupts operations and requires extensive repair and replacement of failed assets. The annual cost of corrosion worldwide was estimated to exceed $U.S.2.5 trillion in 2016, which translates to 3 to 4% of the Gross Domestic Product (GDP) of industrialized countries according to NACE IMPACT study report. (...) To reduce the huge cost and the environmental impact of corrosion and enhance the sustainability of materials used for construction, available corrosion control practices such as proper material design and selection, the use of corrosion inhibitors, coatings, cathodic protection etc., are recommended and could lead to savings of between 15 and 35% of the cost of corrosion. This translates to between US$375 and $875 billion annually"
