Ethylene release when unplugging

Gepubliceerd op 18/12/23 1 Views

In 1989 the Philips Pasadena disaster started after an ethylene release that ignited. High pressure ethylene might have been used to blow out residual PE polymer from a reactor settling leg. A LOTO locked ball valve was opened to do so.

Ask yourself and your crew:

  • How can something like this happen here (e.g. on our site)?
  • What safety measures (i.e. procedures, controls/barriers) do we have in place to mitigate the risk?
  • How do we know the risk controls/barriers are working?
  • What improvements or changes should we make to the procedures, controls/barriers or the way we work?
