Lessons Learned from Explosion at Methyl Isocyanate Plant

Safety


Bayer CropScience sought to reduce risks associated with the manufacturing and storage of the toxic chemical methyl isocyanate (MIC) at its processing plant in Institute, West Virginia, says a new congressionally mandated report from the National Research Council. However, the company did not make an effort to incorporate all possible hazard control methods, and the report found that not all chemical manufacturing plants have adopted safer processes that aim to minimize or eliminate hazards. The committee that wrote the report recommended that the US Chemical Safety Board (CSB) or another entity develop a framework to help managers at chemical plants choose among alternative processing options—considering factors such as safety, environmental impact, and product yield—to develop a safer chemical manufacturing system.

The 2008 explosion at the West Virginia Bayer plant, which stemmed from a fire within the production unit, resulted in the deaths of two employees and extensive damage to nearby structures. Debris from the blast hit the shield surrounding a storage tank for MIC—a volatile, highly toxic chemical used in the production of agricultural and residential pesticides. The liquid and vapor forms of MIC can be harmful when inhaled or ingested, or when eyes or skin are exposed to it. In 1984 a cloud of MIC gas from an explosion in Bhopal, India, killed nearly 3,800 people. Although the storage container at the West Virginia plant avoided damage, an investigation by the US Chemical Safety and Hazard Investigation Board found that debris could have struck a relief valve vent pipe resulting in the release of MIC into the atmosphere. Bayer intended to restart production of the pesticides involving MIC after plant modifications were complete, but last year announced it would cease production. Nevertheless, under the congressional mandate, the Research Council study examined the use and storage of MIC at the Bayer facility and possible alternative production processes.

Inherently Safer Process Assessments

OSHA process safety management regulations require companies to follow evaluative and organizational procedures to ensure a safe chemical manufacturing process. Companies must meet OSHA’s requirements, but are not limited to them, when additional hazard control methods are available. One of these additional methods is an inherently safer process assessment, which aims to minimize or eliminate the hazard. These assessments will not always result in a clear, well defined, and feasible path forward. Although one process may be inherently safer with respect to a specific hazard, the process may present other hazards, such as an increase risk of fire or more severe environmental impacts. For instance, changing from a flammable solvent in a process to a non-flammable one will eliminate a fire hazard, but if the new solvent is toxic, then using it introduces a new hazard that must be controlled. Moreover, judgments about what constitutes an inherently safer process varies among professionals, and the chemical industry lacks a common understanding and set of practice protocols for identifying safer processes.

The committee found that Bayer did incorporate some aspects of risk reduction that are associated with inherently safer process principles. However, the inherent safety considerations were not explicitly stated in Bayer’s process safety management guidelines and were dependent on the knowledge base of the individual facilitating the particular activity, such as a process hazard analysis. Moreover, Bayer and the previous owners of the plant performed hazard and safety assessments and made business decisions that resulted in MIC inventory reduction, elimination of above ground MIC storage, and adoption of various measures, but these assessments did not incorporate some of the key principles of the inherently safer process. The committee said that without an emphasis on incorporating inherently safer process assessments into process safety management, it is unlikely that these concepts would become part of corporate memory, and therefore could be forgotten or ignored over time. It suggested that Bayer formally incorporate inherently safer process assessments into the company’s process safety management system and training, and to record such assessments as part of its audit and review processes.

Alternative Methods for Producing MIC and Pesticides

In reviewing Bayer’s assessment of four alternative processes for the manufacture of MIC, the committee said that no method out-performed all others in every category. Bayer also evaluated trade-offs among the alternatives—considering costs and benefits such as risk, expense, quality of final product, and community perception—but excluded factors that could have been important in the decision, from the perspectives of both the company and the community. Although it posed higher risks to the surrounding community due to the volume of MIC stored at the facility, the process Bayer ultimately chose decreased the amount of wastewater produced compared with other methods, which in turn decreased the potential damage to local surface waters. The previous owners identified other possible methods that could have resulted in a reduction in MIC production and inventory but determined several limitations prohibited their implementation.

Inherently Safer Processes in Industry

A company’s consistent application of inherently safer process strategies could decrease the required scope of organizational emergency preparedness programs by decreasing the vulnerable zones around its facilities. However, a potential concern with using inherently safer process analysis is that it may become too narrowly focused, and as a consequence, may overlook certain outcomes. Even when multiple outcomes are recognized, they may be inappropriately weighted.

The committee recommended that the US CSB or other entity convene a working group to chart a plan for incorporating decision theory frameworks into inherently safer process assessments. The group should identify obstacles to employing methods from the decision sciences, options for tailoring these methods to the chemical process industry, and incentives that would encourage their use.

How to Prepare for OSHA’s Globally Harmonized Hazard Communication Standard (GHS)

OSHA has issued a final rule revising its Hazard Communication Standard, aligning it with the United Nations’ globally harmonized system (GHS) for the classification and labeling of hazardous chemicals. This means that virtually every product label, MSDS (called “safety data sheet” or SDS under the new standard), and written hazard communication plan must be revised to meet the new standard. Worker training must be updated so that workers can recognize and understand the symbols and pictograms on the new labels as well as the new hazard statements and precautions on SDSs.

Environmental Resource Center is offering webcast training for you to learn how the new rule differs from current requirements, how to implement the changes, and when the changes must be implemented.

OSHA Kicks off Heat-Related Illnesses and Fatalities Prevention Campaign

OSHA has kicked off a national outreach initiative to educate workers and their employers about the hazards of working outdoors in hot weather. The outreach effort builds on last year’s successful summer campaign to raise awareness about the dangers of too much sun and heat.

“For outdoor workers, water, rest, and shade are three words that can make the difference between life and death,” Secretary of Labor Hilda L. Solis said. “If employers take reasonable precautions, and look out for their workers, we can beat the heat.”

Every year, thousands of workers across the country suffer from serious heat-related illnesses. If not quickly addressed, heat exhaustion can become heat stroke, which has killed—on average—more than 30 workers annually since 2003. Labor-intensive activities in hot weather can raise body temperatures beyond the level that normally can be cooled by sweating. Heat illness initially may manifest as heat rash or heat cramps, but quickly can become heat exhaustion and then heat stroke if simple prevention steps are not followed.

“It is essential for workers and employers to take proactive steps to stay safe in extreme heat, and become aware of symptoms of heat exhaustion before they get worse,” said Dr. David Michaels, assistant secretary of labor for occupational safety and health. “Agriculture workers; building, road, and other construction workers; utility workers; baggage handlers; roofers; landscapers; and others who work outside are all at risk. Drinking plenty of water and taking frequent breaks in cool, shaded areas are incredibly important in the hot summer months.”

In preparation for the summer season, OSHA has developed heat illness educational materials in English and Spanish, as well as a curriculum to be used for workplace training. Additionally, a website provides information and resources on heat illness—including how to prevent it and what to do in case of an emergency—for workers and employers. The page is available at http://www.osha.gov/SLTC/heatillness/index.html.

OSHA also has released a free application for mobile devices that enables workers and supervisors to monitor the heat index at their work sites. The app displays a risk level for workers based on the heat index, as well as reminders about protective measures that should be taken at that risk level. Available for Android-based platforms and the iPhone, the app can be downloaded in both English and Spanish by visiting http://s.dol.gov/RI.

In developing last year’s inaugural national campaign, federal OSHA worked closely with the California OSHA and adapted materials from that state’s successful campaign. Additionally, OSHA is partnering with NOAA for the second year to incorporate worker safety precautions when heat alerts are issued across the nation. NOAA also will include pertinent worker safety information on its heat watch website at http://www.noaawatch.gov/themes/heat.php.

OSHA and the Laser Institute of America Renew Alliance to Protect Workers from Laser Hazards

OSHA has renewed its Alliance with the Laser Institute of America (LIA) to reduce and prevent worker exposure to laser beam and non-beam hazards in industrial, research, and medical workplaces. The Alliance will also share information on laser regulations and standards, effects lasers have on the eyes and skin, laser control measures, and laser safety program administration.

“Worker exposure to laser beams can result in eye and skin damage, and in more serious cases, blindness and skin cancer,” said Assistant Secretary of Labor for Occupational Safety and Health David Michaels. “This renewed Alliance will help broaden outreach efforts to workers and employers and share critical education and information to reduce preventable injuries.”

During the two-year agreement, the Alliance will develop fact sheets with questions that should be asked at facilities that use lasers, and will conduct Laser Safety Seminars for OSHA field staff.

LIA, founded in 1968, is a professional society for laser applications and safety, and it provides technical information and networking opportunities to industrial, medical, research, and government communities worldwide. LIA represents approximately 1,500 members.

OSHA’s Safety and Health Topics pages on Laser Hazards, Laser/Electrosurgery Plume, and Radiation provide information on how to recognize and reduce laser hazards, OSHA standards related to lasers, and training on laser safety.

Through the Alliance Program, OSHA works with groups committed to worker safety and health to prevent workplace fatalities, injuries, and illnesses. These groups include unions, consulates, trade or professional organizations, faith- and community-based organizations, businesses, and educational institutions. OSHA and the groups work together to develop compliance assistance tools and resources, share information with workers and employers, and educate workers and employers about their rights and responsibilities.
