What you do not see is most dangerous in Process Safety. Corrosion is a major problem in the chemical process industry and I am observing a disturbing trend. Regular painting and maintaining of metallic structures and equipment is often delayed when budget pressures dominate. Corrosion is insidious. It slowly and surely kills. If you do not have a good corrosion monitoring and control system, you will one day run out of luck, with disastrous consequences. An article by Dr A K Samant of ONGC mentions the following:"Corrosion control is an important consideration. The periodic monitoring techniques and analytical assessment of corrosion severity is very important and critical since it provides the direction to ensure proper utilisation of materials and corrosion control methodologies. Therefore, correct and appropriate condition assessment techniques should be used to avoid premature failure and ensure maximum safety".
