Introduction
A huge fire erupted at Chevron Richmond Refinery on August 6, 2012, resulting in a cloud of toxic smoke spreading throughout the town and prompting 15,000 inhabitants to seek medical attention. The Chevron Richmond Refinery is situated in Richmond, California, on a 1,200-hectare property on San Francisco Bay. It is the largest employer in the city (the refinery has 1,200 staff) and processes up to 250,000 barrels per day, with the primary products being diesel fuels, motor gasoline, lubricants, and jet fuel. The chemical accident was caused by old infrastructure and poor disaster management policies. For instance, the explosion resulted from a failure in one of the pipes after years of thinning from channeling crude oil containing high levels of sulfur: sulfur is the primary corrosive element in crude oil pipes. Furthermore, management ignored previous requests for safer equipment, and upon learning of the leak several hours before the fire, they took actions that increased the risk. This essay will reflect on the Chevron Richmond Refinery fire, including the incident's circumstances, the contributing factors to the explosion, and relevant lessons gained from the chemical accident.
Background
On August 6, 2012, a chemical accident at Chevron Richmond Refinery in the #4 Crude Unit owing to a ruptured pipe. The disastrous pipe failure occurred at the "4-sidecut" stream, one of the many process streams in the plant's C-1100 crude Unit Atmospheric column.
