The U.S. Chemical Safety and Hazard Investigation Board (CSB) is highlighting the important role of individual state governments in driving critical chemical safety change.
A number of state governments have made significant safety improvements following a chemical disaster within their state to protect their residents and the environment with the common goal of preventing future similar incidents.
The CSB has issued 80 safety recommendations to 22 different state governments stemming from 27 CSB investigations.
Currently, only six of these investigations still have open recommendations issued to state governments. These CSB recommendations range from identifying risks and
increasing safety inspections to developing and adopting significant, state-level chemical safety legislation.
Several states have taken significant steps to implement positive safety changes in light of chemical disasters.
The following are some notable examples:
Following a 2007 propane explosion that occurred at a general store in Ghent, West Virginia, killing four people, the CSB issued a recommendation to the Governor and
Legislature of the State of West Virginia aimed at improving propane training requirements for propane technicians. West Virginia approved a bill in 2010 requiring the completion of a nationally recognized propane service training program for “persons who install or maintain liquefied petroleum gas systems.” This requirement was also implemented into the West Virginia State Fire Code.
On February 7, 2010, Kleen Energy, a natural gas-fueled power plant under construction in Middletown, Connecticut, experienced a catastrophic natural gas explosion that killed six and injured at least 50 people. The incident occurred while workers were conducting a “gas blow,” where natural gas is forced through new piping and released into the atmosphere at a high pressure and volume in order to remove debris. As a part of its investigation, the CSB issued a recommendation to the Governor and Legislature of the State of Connecticut to enact legislation that prohibits gas blows.
In 2014, the CSB issued a recommendation to the Governor and Legislature of the State of California to enhance and restructure California’s process safety management
regulations for petroleum refineries. The state of California amended its Occupational Safety and Health Process Safety Management (PSM) standard in 2017 to improve workplace safety and hazard prevention and management at California’s 15 petroleum refineries.
The newly adopted standard, which became effective on October 1, 2017, requires that refineries, among other things, perform a damage mechanism review for each existing and new mechanical, chemical, physical, or other processes that result in equipment or material degradation. Refineries are also required to eliminate hazards to the greatest extent feasible using inherent safety measures.
