About me

Process safety grounded in everyday industrial reality

My name is Mathias Lindqvist and I run PSL AB. I help industrial companies understand and manage risks in processes and plants, with a focus on risk assessments, HAZOP, ATEX zone classification and technical documentation.

I have worked in industry since 1997. My background covers process operations, electrical and instrumentation work, maintenance, ATEX and process safety – from hands-on work in plants to regional safety assignments.

About me

  • A pressurized system at an industrial plant

    Risk analysis and HAZOP

    We identify the events that could occur in the plant and use HAZOP to systematically capture risks and operability problems in the process.

  • A sign for acetylene with warning symbols and a yellow EX warning triangle on a red door

    ATEX and zone classification

    We classify areas where an explosive atmosphere can form, so that the right equipment is chosen and the risk of ignition is kept down.

  • A labeled regulator and valve assembly with pressure gauges at the plant

    Documentation and review

    We produce flow diagrams, component specifications and a clear picture of the plant's status, with a prioritized list of actions.
