In April 1992, nine explosions rocked the City of Guadalahara, Mexico. The explosions opened a two kilometer trench, killed 215 people, injured hundreds, and damaged sixteen hundred buildings. Damages were calculated at 75 million US dollars. The event was the result of corrosion. A corroded water line leaked and caused the corrosion of a buried gasoline line. As a result, the gasoline line corroded and leaked its contents into a porous sewer line. The gasoline flumes mixed with air from the surface and street traffic ignited the explosive combination. Corrosion is often viewed as rust, to be painted over, and forgotten. As you will see in this course, corrosion is a serious matter that should be near the top of your “To Do” list. Corrosion is often hidden or masked; not visible without investigation. Corrosion can be dangerous to the system and to your health. Corrosion is always costly.
