  • Understanding Fire and Gas Systems Increases Safety

    SummaryUnderstanding Fire and Gas System FunctionsUnderstanding SensorsDetecting FiresA Systemic ApproachBy Edward Naranjo, Director of Rosemount fire and gas detection systems, Emerson Although many process plant employees have some understanding of fire and gas systems, the very nature of these systems – isolated and separate from basic process control and acting only during accidents – may cause workers to take them for granted. Like a smoke detector at home, a fire and gas system, once installed, can easily fade into the background. When workers acquaint or reacquaint themselves with the critical roles provided by fire and gas systems, it improves overall safety. Fire and gas system engineering is a specialized field made more complex as the practices for designing and maintaining systems through their lifecycle have evolved over the years. Much changed with the advent of prescriptive standards developed by the National Fire Protection Association, European Community and most recently, International Electrotechnical Commission (IEC) 61511 and International Society of Automation (AN...
