Kenexis is an engineering and consulting firm specializing in the application of engineering safeguards,
such as safety instrumented systems, to the process industries. As a result, we have detailed understanding of the
requirements of chemical process, in terms of what actions SIS need to take and how to implement them. Our
instructors are leading experts in their respective fields, often published authors on the topics being discussed
with years of real-world experience that form the basis for the course materials and examples.
While Kenexis is prepared to provide custom training on a broad range of topics that are related to
engineered safeguard design and implementation, our most sought after training has been packaged into the following courses.
Safety Instrumented System Engineering - Part 1
Safety Instrumented System Engineering - Part 2
Fire and Gas Systems
Burner Management Systems

Bypassing Safety Instrumented Systems
Kenexis training is available in a number of ways. The most effective training involves direct participation
of Kenexis instructors and your staff, on your site, using your process equipment as examples in the training effort. On
site courses are available on the core courses listed above, or any customization that you require. We also provide open
enrollment courses that are available to the public at a number of locations every year. In addition, we offer distance
learning via web seminar on most of our training courses. If you are interested in finding out how you can participate in
Kenexis training, contact Ed Marszal at Kenexis at 614-451-7031 ext. 101 or by e-mail

Safety Instrumented System Engineering - Part 1
Front End Engineering Design (FEED)
Safety Lifecycle, SIL Selection, Safety Requirements Specification
Kenexis provides the users of Safety Instrumented Systems (SIS) with training required to cost-effectively implement systems
that are highly reliable, easy to use, and ideally suited for their applications. This course presents core principals of
Safety Instrumented Systems Engineering and is taught by engineers who have years of practical experience in the design of
safety systems. Part 1 spans two days and covers the first half of the Safety Lifecycle. Key topics include identifying the
Safety Instrumented Functions (SIF), specifying a Safety Integrity Level (SIL) for those functions, and writing Safety
Requirements Specifications.

Safety Instrumented System Engineering - Part 2
Conceptual Design and SIL Verification
This course takes up where Part 1 - Front End Engineering Design
- leaves off. Starting with a safety requirements specification, this course explains the conceptual design process and the
factors that are important to achieving the specified performance targets, particularly SIL. Calculation of probability of
failure on demand in order to verify that the quantitative SIL target has been met is covered in detail. Key topics include
working with failure rate data, performing reliability calculations to determine SIL achieved, incorporating the effect of
diagnostics, understanding the relationship between testing and SIL, and reviewing safety equipment technology and architectures.

Fire and Gas Systems
Fire and gas systems are an important tool for safeguarding process plants and production facilities that handle
flammable and toxic materials. In order to make a fire and gas system effective, a systematic risk-based approach should
be used to make key design decisions such as the quantity and placement of detectors. This course presents practical insight
into fire and gas system design. The course uses a blended approach where prescriptive standards are discussed in combination
with performance-based standards including ANSI/ISA 84.01. New standards aid in making decisions about hardware selection
and testing issues that are not adequately defined in the more prescriptive application specific standards for F&G systems.

Burner Management Systems
Kenexis provides the users of Burner Management Systems (BMS) with training required to cost-effectively
implement systems that are highly reliable, easy to use, and ideally suited for their applications. This course presents practical
insight into ensuring safe combustion in boilers, furnaces, heaters, kilns, and other fired equipment. The concepts of Safety
Instrumented Burner Management Systems (SI-BMS) will be presented as the methodology to design BMS to be compliant with national codes
and standards, including NFPA 85, NFPA 86, ANSI/ISA 84.01, API 556, API 14C and BLRBAC.

Machine Safeguarding
Users of industrial machines are
responsible for providing safeguards that prevent workers from being exposed to hazardous motion of the machine. These
safeguards range from physical barriers to electronic interlocks that include programmable electronic systems and sophisticated
sensors such as light curtains and laser scanners. This course presents an overview of the tasks and techniques necessary for
effective machine safeguarding. Key topics include the safety lifecycle for machinery, risk assessment (ANSI B11.TR3), selecting
appropriate safeguards, design of safety critical circuits (control reliable and EN 954 Categories), safety distances, and
validation and verification.
Bypassing Safety Instrumented Systems
Kenexishas developed a training course for Bypassing Safety Instrumented Systems
(SIS) that provides critical guidance and procedures that should be considered
prior to defeating any safety critical system. Bypassing SIS takes understanding
of the process and knowledge of the reasons when bypass is acceptable. Many
plants have had catastrophic events related to improper bypass. In this course,
our instructors explain what analysis is required and what level of review is
necessary to determine when Bypassing SIS is the correct option and how
accidents can occur if these procedures are not followed. Kenexisreviews the
requirements for bypassing in SIS standards, how bypasses can be accomplished
(including their strengths and limitations), management of change, and proper
documentation and auditing.
