Four workers recently died as a result of an accident at the 600-acre DuPont chemical plant in La Porte, Texas, and seven federal investigators from the Chemical Safety Board (CSB) arrived shortly thereafter in the city of 35,000, which is located 25 miles east of Houston. What has garnered much of the attention of Houston industrial accident attorney professionals is the fact that this plant has not received a workplace safety inspection in seven years. Perhaps more disturbing, however, is how few inspections ever take place. CSB investigators are likely most interested in discovering how this deadly incident occurred without an explosion or fire, which is unusual for a chemical plant accident that results in multiple fatalities. The organization has also inspected DuPont after accidents at its facilities in New York and West Virginia in 2010. Methyl mercaptan is a poisonous gas known for its distinctive rotten egg smell that is used in products such as jet fuel and pesticides. A chemical leak at the plant on Nov. 15th caused the death of four workers who were responding to the accident. A fifth employee recovered from the chemical plant accident after a brief stay in a hospital. The company stated later in the day that no danger was posed to the residents in La Porte and the leak was contained in the plant itself. The last time that methyl mercaptan was involved in a major accident in the United States occurred in 2001 in Riverview, Mich., a city located 15 miles south of Detroit. It was released from a rail tank car and ignited, killing three Atofina employees. When the Occupational Safety and Health Administration (OSHA) last inspected this plant in 2007, it found two serious violations related to highly hazardous materials, and the company was fined $1,700 for each of those violations. Unfortunately, OSHA inspections simply do not happen very often in general. About 2,000 inspectors work for the organization, and they are responsible for ensuring that 8 million workplaces are safe. On average there is one inspector for 67,847 workers and this means a federal inspector visits a given plant every 139 years or a state inspector every 79 years. In the seven years that have passed since the last inspection, the Texas Commission on Environmental Quality has cited DuPont about 25 times for state law violations related to issues such as the company's failures to prevent pollution leaks. For example, 37,000 pounds of sulfur dioxide were released at the plant over a three-hour period in September while 40 pounds of chlorine were leaked in August 2013. DuPont was fined thousands of dollars as a result of these violations. According to Environmental Protection Agency (EPA) records, the plant is also not compliant with air emissions and hazardous waste management standards and has been penalized more than $100,000 due to violations that took place in 2012 and 2014. The EPA and DuPont have also been in discussions related to air emissions, hazardous waste management and waste water treatment since an EPA inspection of the plant in 2008. Although every Houston wrongful death in an industrial accident is tragic, it is unfortunate that about 5,000 workplace deaths that take place in the United States every year, an average of about a dozen every day. Nearly 4 million work-related illnesses and injuries are reported on an annual basis as well. Perhaps the most recent workplace accident that received significant attention was the explosion at a fertilizer plant in West, Texas, a city located 20 miles north of Waco, Texas, that resulted in 14 deaths in 2013. The last time that an OSHA inspector had visited that plant was in 1985.
