Fire and Gas System
The fire and gas system is a plant’s protection system. This system will detect a threatening hazard and respond with the activation of a final control element to prevent harm to personnel or damage to equipment. The fire and gas system is dependent on various types of detectors to sense potential hazards before they get out of control. The fire and gas systems must be checked for functionality on a routine basis. Documentation is essential for training, record keeping, and troubleshooting.
This course has been designed to cover an introduction to the fire and gas system, including associated hardware and wiring. In addition to covering the hardware, the course will explore the required software logic that must be programmed into the system to meet the needs of the plant’s shutdown philosophy. The fire and gas system’s preventative action protocol will also be discussed.
Upon completion of the course, participants will have a better understanding of the operations, maintenance, and testing associated with a fire and gas system. This exposure will better prepare technicians to further expand their knowledge base during on-the-job training and practical experience at the plant site.
Fire and Gas Hardware
- Wiring and documentation
- Control system logic
- Display, indication systems, and final control elements
Participants will become familiar with the basic principles of fire and gas detectors, wiring, and documentation on the first day. They will learn about the control logic which determines the conditions that will trigger the fire and gas system. They will also learn about the alarm indication systems, as well as the interface to the Distributed Control System (DCS). Final control elements that generate protective actions determined by the logic of the system will also be covered.
Fire and Gas Operation
- Testing and maintenance
- Confirmed fire and gas
- Combined Safety System (CSS)
- Shutdown philosophy
- Cause and Effect (C&E) and Process and Instrumentation Diagrams (P&IDs)
On the second day, participants will become familiar with the operation, testing, and documentation involved when checking the fire and gas system. They will learn about confirmed fire and gas, the connection between the fire and gas and Emergency Shutdown Devises (ESD) systems, and combined safety systems which are all parameters of the plant’s shutdown philosophy. In order to become more familiar with the fire and gas system in a particular plant, participants must become familiar with C&E and P&IDs.
This course is mainly targeted to process operators, process technicians, and laboratory and maintenance personnel. The course can also be applicable to employees working with equipment and materials purchasing, equipment procurement, job planning, as well as immediate supervisors to the working technicians.
Participants should have some recent exposure to fire and gas terminology in the oil and gas industry.
