For nearly two centuries, businesses around the world have relied on FM Global and its property loss prevention data sheets to reduce risk at their facilities. Data Sheet 7-14, Fire Protection for Chemical Plants, addresses fire and explosion hazards at chemical manufacturing plants and similar processing facilities, particularly those associated with ignitable liquid, flammable gas, and liquefied flammable gas where a release could result in a fire of long duration. In 2014, FM Global assigned a team of engineers to update the data sheet, which had not undergone a major revision in over 15 years. A primary focus of the revision was to reduce reliance on prescriptive guidelines when designing fire protection systems at chemical plants. Renewed emphasis was placed on identifying potential fire/explosion scenarios, and designing fire protection systems appropriate for the anticipated loss scenario. Additionally, safeguards to minimize the volume of the potential liquid or gas release were developed, such as accidental release control systems, siting guidance, and other passive methods to mitigate damage in the event of a release. This new guidance is based on a mixture of scientific research, loss history, and engineering experience. (C) 2016 American Institute of Chemical Engineers Process
