Many of us can see examples of corrosion in the form of rust on a daily basis: driving to and from work on highways or bridges, in buildings, parking structures and even in our cars.
Corrosion is the process which uniformly weakens or gradually destroys materials by electrochemical interactions. Microbiologically influenced corrosion, also known as MIC, is a form of corrosion defined in the Fire Protection Handbook as an electrochemical corrosion process that is concentrated and accelerated by the activity of specific bacteria within a fire-sprinkler system resulting in the premature failure of metallic system components.
