How Teams Can Avert High Potential Hazardous Incidents (Part 1) Over Pressure

Although lost time and recordable injuries are on the decline, Serious Injuries & Fatalities are staying constant.  This video looks at how over pressure incidences can be reduced by the involvement of teams.

    Dear Brett,

    I have listened to your video and it is really interesting. I’m Process Engineer working as a plant operator in Canola Oil plant. My team leader recently faced an accident by exploding the pressure vessel of the dissolve air flotation system (DAF) in the wastewater treatment plant. He operated the vessel to pressurize it but it went over pressure soon. However Pressure Relief Valve didn’t work and vessel exploded. Fortunately he narrowly escaped. So what you are explaining here are very important area need to be focused and definitely require adequate training.

    Thanks with best regards

    This video presentation provides significant safety information for everyone handling or within the vicinity of pressurised systems. I have had the opportunity 0f working on industrial steam boilers in processing operations environment. I know the adverse consequences that may erupt if adequate safety measures are not ingrained within the boiler units to manage pressure variations. Steam boiler explosion is most commonly associated with overpressure within the system.

  3. Hi,

    It was a nice presentation and thanks for sharing.

    As you said we have many safety layers prior to PSV popping up i.e. alarms, operator response, normal process control, SIS and then PSV and ultimately incident response plan. I agree with you on the aspect of teacing every one in the plant about the importance, location and protected equipments related to each PSV but in addition to teaching how to design a PSV in a operating facility, i think following may add more value,
    1. Potential conseqence of an event i.e. if operator do not respond timely, what is the assosiated risk and its probability
    2. During the plant operation if there is any change, importance of revisiting the assodaiated PSV design (if there is a modificayion in the plant from operation view point but PSV design is not revisited it may result in an undersized PSV).
    3. Awareness about final response plan and mock drills are important.
    4. Maintance plan shall ensure that all PSVs are in good condition throughout the plant life and consider spare PSVs where required.

    Please feel free to suggest, if you think otherwise.

  4. Hi Brett
    This was a superb presentation and has taught me a lot. I have the responsibility of mentoring young engineers and technicians on our plant and your presentation gives me knowledge to assist them.
    Kind Regards
