Kenexis is a process safety consulting engineering firm that provides technical safety services for new and existing facilities including performance-based fire and gas mapping, and risk analysis for industries that manage risks related to chemicals or stored energy.

We specialize in analyzing risks of any process under control or material in containment in order to quantify the hazard, design reduction targets, and ensure the selected targets are met.  Analysis is done using a risk-based process where the selected equipment, maintenance, and testing procedures are tailored to specific requirements of an application.  The risk-based approach yields a design that provides the required risk reduction at a manageable cost.

We provide ISA/IEC 61511 process safety consulting engineering services for OSHA Process Safety Management (PSM) including software and training.

Green Energy

Does green mean safe too? Storage of large amounts of energy, regardless of whether it is in the form of hydrocarbons, lithium-ion batteries, compressed hydrogen, or anhydrous ammonia, can result in the unintentional release of that energy…

SIS and BPCS Component Sharing

There is still some confusion about a key attribute of good Safety Instrumented Systems (SIS) design – specifically separation of Basic Process Control Systems (BPCS) and Safety Instrumented Systems (SIS).

In this live webinar, we will cover:

Definitions and Standards Requirements
Assessment of Independence – Shared Valve System
Quantitative Justification of Shared Component
Additional Standards Requirements
Design of SIS Separation Workflow

Date: Tuesday 16 August 2022
Time: 9 AM Eastern, 1:00 PM Greenwich Mean Time (GMT)

Previously Recorded Webinars:

Determining and Documenting Appropriate Leak Tightness Requirements

This webinar was well attended with many questions and comments, and you asked for more. The webinar went into detail about the differences between tight shut off and leakage rate methods, the standards, and how to determine the correct leak requirements for your situation.

We did not record the webinar, however it is available on our Process Safety Training Center site.

If you want, you can request a 3-day Process Safety Training Center trial request and view the recorded training session as well as other training available on the site. Click here to request the trial,

Once you log into the site, there is a Training button in the button bar to the right shown in the image below. That button will take you to training. Once you are in the Training section, the Browse Available Courses link near the bottom will take you to the course list. You want the Safety Requirements Specifications (SRS) course. Once the course is open, click on the Subscribe button to enter the course and Section 14 – Valve Leakage Rates covers Standards Requirements, Leak Tightness Definitions, Selecting Leakage Class Approaches, and Valve Leakage Specification Workflow. You can even take the quiz at the end if you want.
