Webinar "How can the Captive Key Concept contribute to Process Safety"
Thursday 7 March 2024 from 15:00 - 16:00 (CET).

This webinar will be facilitated by Sofis with Stephan Sadowski as speaker.

Incorrect valve operations can have catastrophic consequences. High risk hazards such as overheating, over-pressure, process misalignment or human error can cause severe safety breaches. These can even lead to fire and explosion. Despite having regulations and operation practices in place to prevent such catastrophes, they can still occur.

As an independent layer of safety, the captive key system guides the operator through the sequence of operational steps during the switch over process. The webinar will give an impression based on some typical applications, even for complex processes, how the captive key concept can contribute to the process safety of your plant.

Aspects to be discussed in an interactive setting

  • Implementation of an independent layer of safety
  • Ensuring safe and ‘right-first-time’ valve operation
  • Guarantee manual valve operations to take place in a safe sequence
  • Eliminate human error

You can register free of charge using the online registration form after which you will receive a confirmation email with the link (Microsoft Teams) to join.

Webinar for EPSC members only
10 two-hour webinar series on the Chemical Hazards Engineering Fundamentals (CHEF) package

DOW has developed during 30 years the Chemical Hazards Engineering Fundamentals (CHEF) package, that is a set of fundamentals and principles to understand consequences of chemical leakages. EPSC offers the employees of the EPSC members to learn about these Fundamentals in a 10 two-hour webinar series (free of charge). The training is provided by Ken First and Bruce Vaughen (through CCPS) who have been developing these CHEF in their career.

The training is necessary to join the EPSC RAST Users Group. RAST is a tool that is using the CHEF formulas for fast screening of consequences.

The first session starts on 10 January 2024, followed by sessions on 17, 24 and 31 January + 7, 14, 21 and 28 February +  6 and 13 March. Each session is from 15:00 - 17:00 (CET / Paris time).

Employees of EPSC members that wish to join can send an email to
