Course Description:
This course focuses on the engineering requirements for the specification, design, analysis, and justification of safety instrumented systems for the process industries. Students will learn how to determine safety integrity levels and evaluate whether proposed or existing systems meet the performance requirements. This course is designed to meet the competency requirements for the national certification from the Instrumentation Society of America (ISA). Those who successfully complete this course and pass the exam (separate testing fee) receive the designation of ISA84 SIS Fundamentals Specialist (ISA84 SFS).

Polk State College Mission and Program Outcomes

Polk State College, a quality driven institution, transforms lives through the power of education by providing access to affordable associate and baccalaureate degrees, career certificates, and workforce employment programs, delivered by diverse, qualified faculty and staff. In line with this purpose, Polk State’s Associate in Science and baccalaureate degree programs develop competence in various career-related skills. This course focuses on the development of competencies related to the following program outcomes:

A primary focus of this course is competence related to the safety of instrumented systems for the process industries.

Course Objectives:
Upon the successful completion of this course, students will be able to:

Differentiate between process control and safety control
Implement the ISA84 standard
Evaluate process risk levels
Calculate Safety Integrity Levels (SILs) using a variety of techniques
Analyze the performance of different logic system technologies
Analyze the performance of various sensor, logic, and final element configurations, as well as the impact of diagnostics, test intervals, common cause, system size, and more
Calculate optimum system test intervals
Specify and select safety instrumented systems
Apply the documentation requirements for process safety management, regulations, and industry standards

Course Content:

Introduction: Danger of Overconfidence and Complacency | Lessons Learned from Past Accidents
Guidelines and Standards: ANSI/ISA | OSHA | IEC | API | NFPA
General SIS Design Considerations: Design Life Cycle | Separation of Control and Safety | Independent Safety Layers
Hazard and Risk Assessment: Hazard Identification | Risk Assessment
Failure Rates and Modes: Safe vs. Dangerous | Failure Mode vs. Technology | Failure Rates | Test Intervals
System Technologies: Pneumatic | Relays | Microprocessors
Operations and Maintenance: Installation | Bypassing | Testing

Classroom/Laboratory Exercises:

Calculate device failure rates and determine safe vs. dangerous performance
Model the impact of field devices, automatic diagnostics, manual test intervals, common cause, and more
Determine the SIL (safety integrity level) of a sample process and design a SIS to meet the performance requirements

A hand-held/scientific calculator should be brought to class.

Textbook and Other Requirements

Textbook information is provided in the course syllabus, at the campus bookstore, on the campus bookstore website (www.polk.bncollege.com), or via the “Shop Textbooks” button on the PASSPORT schedule of classes.

College-Level Communication and Computation Skills

State Rule 6A-10.030 does not apply to this course.

Student Help

The professor is available for help during posted hours and by appointment during other non-class hours. Each student is encouraged to seek assistance from the professor. To further the educational process, the Learning Resources Centers, comprised of the campus Teaching/Learning and Computing Centers (TLCCs), JDA Student Success Center, and campus libraries, are available for student use. Each resource provides qualified staff and up-to-date equipment and facilities to promote academic success. The TLCCs and JDA Student Success Center provide tutoring services, computing resources, and other instructional support. The library provides information resources, individual and group study space, research assistance, information literacy instruction, and computing resources. Each facility provides free wireless access to the Internet. The Polk State College Library, Student Success Center, and TLCC hours of operation and tutoring schedules are posted at each facility and on the College website.

Withdrawing From a Course

A student may officially withdraw from a course during any given term, provided he or she follows the appropriate policy and procedure. Following the conclusion of the Drop period, students may officially withdraw without receiving a grade from any course, provided they do so no later than the published withdrawal deadline. The published deadline reflects approximately (but no more than) 70% of the term, based upon the course’s scheduled duration. It is the student’s responsibility to submit these withdrawal forms; failure to do so may result in a grade of F in the course. Under the Forgiveness Policy, a student is allowed only three attempts in any one course: one initial enrollment and two repeats. A student is not allowed to withdraw from a third course attempt. Limited admission programs may have specific guidelines regarding course withdrawal that vary from this policy; these guidelines are listed in the specific program handbooks. If a student stops attending class, the grade earned, usually an F, is assigned and posted. Prior to withdrawing from a course, the student should consult with the Financial Aid Office to determine what impact, if any, withdrawal from the course will have on his or her financial aid status. A student cannot use course withdrawal to avoid academic dishonesty penalties. A student who has been penalized for academic dishonesty in a course is not eligible to withdraw from the course.

Repeating a Course

Under the Forgiveness Policy, a student is allowed only three attempts in any one college credit course: one initial enrollment and two repeats. Under certain circumstances, a student may petition to repeat a credit course beyond the third attempt. Limited admission programs may have specific guidelines regarding repeating courses that vary from this policy; these guidelines are listed in the specific handbooks. The student should be aware that repeating a course may result in a higher course cost. A course cannot be repeated unless the previously earned grade is a D, F, or W (the Polk State Catalog provides further details regarding this process). Prior to repeating a course, the student should consult with the Financial Aid Office to determine what impact, if any, repeating the course will have on his or her financial aid status.

Academic Dishonesty

Each student is responsible for his or her work. It is assumed that each student is honest and will abide by this standard; however, in the event that there is an indication or suspicion of cheating or plagiarism, the situation shall be dealt with in accordance with the published College policy. Copies of this policy are available in the Student Services Office. More specific information can be found in the Course Syllabus.

Information Technology Access/Use Policy

The information technology resources provided by Polk State College (this includes, but is not limited to, telephones, computers, the Polk State Local Area and Wide Area Networks, and the Internet) must be used for academic purposes only. Use of these resources is a privilege, not a right. Inappropriate use can result in revocation or suspension of this privilege.
