Further Information - MIST (Minimum Industry Safety Training) Course - OPITO approved


OPITO Minimum Industry Safety Training (MIST) Further (Code: 5311) is the learning and assessment programme for experienced offshore workers.

You can complete your MIST online if you have a Vantage POB number and you have previously worked offshore in the UK Continental Shelf (UKCS) or internationally.

You can also renew your MIST online if you already have a valid OPITO MIST Initial or valid OPITO MIST Further training certificate.

Your 4-year OPITO MIST Further Training (Code 5311) certificate will be provided by email upon completion of the course. Existing MIST certificates can be renewed up to three months in advance of the expiry date. Your new MIST certificate will be valid for four years from the previous expiry date.

This three-hour eLearning course includes assessment and content on five key areas:

  • Major Accident Hazards
  • Workplace Hazards and Personal Safety
  • Risk Management
  • Control of Work
  • Helicopter Safety

The MIST Online course requires a 100% pass mark. This means that all the assessment questions must be answered correctly before receiving your certificate. The technology in MIST Online will remember which questions you failed and will present you with the related content again and a different set of questions to confirm your understanding. This process will continue until all questions are answered correctly and the course is complete.

    Note: If you have previously done the MIST 2-day classroom course and it is now due to expire following 4 years' validity, then you are also eligible to do the MIST online refresher course.

  • Do you need MIST to work offshore?

    OPITO states that the MIST course is 'highly recommended' for anyone working offshore in the UK and, Since 2009, it is expected that anyone working offshore in the UK has a valid MIST certificate. The MIST Online training is the learning and assessment programme for experienced offshore workers to renew their MIST certification every four years.

    Your 4-year OPITO MIST Further Training (Code 5311) certificate will be provided by email upon completion of the course.

  • How long does the online course take?

    Depending on your current level of safety knowledge and awareness, the course duration differs person to person. We would advise allocating 5 hours to complete the course, but the average completion time is around 3 hours. You can stop the course at any point and return to it at a later date if required. The course will remember your progress in each module and therefore you will not lose any of your prior work.

  • What topics are covered in OPITO MIST?

    There are 5 modules in the OPTIO MIST standard:

    • Major Accident Hazards
    • Workplace Hazards & Personal Safety
    • Risk Management

    You can sit the modules in any order and you can also jump out of a current module and start / continue with another one. You are in full control!

  • Why is there an optional Pre-Assessment?

    The pre-assessment is designed to test your existing knowledge and only provide you with the learning content that you need. At the start of each module, you will be offered this optional pre-assessment on the learning objectives in that module. Each question you get correct will be followed by a second question to rule out the 'luck factor', if you correctly answer both questions the content related to that learning objective will be removed from the course. The more questions you get right in the pre-assessment, the shorter the course becomes. If you are keen to see all the content for a particular module, just select the 'skip pre-assessment' option when it is offered to you.

  • How do I get my OPITO MIST Certificate?

    A printable certificate in PDF format will be provided at the end of the course and results will be uploaded to Vantage within 24 hours of completion.
