What is a HAZOP Review?

A HAZOP review is a structured and systematic method used to evaluate potential deviations in process design and operation. These deviations can lead to hazardous situations or cause a system to function in unintended ways. The review is typically performed by a multidisciplinary team including process engineers, safety experts, and operations staff who collectively assess each part of a process using predefined guidewords. Common guidewords include:

  • More 
  • Less
  • Reverse
  • As well as
  • Other than

For each guideword applied to a process parameter (such as flow, temperature, pressure, or composition), the team asks:

  • What could cause this deviation?
  • What would be the consequences?
  • Are there sufficient safeguards in place?
  • What corrective actions might be needed?

This structured questioning leads to actionable insights that reduce risk and improve operability.

Why is a HAZOP Review Important?

Conducting a HAZOP review helps identify:

  • Potential safety risks to personnel and equipment
  • Operational inefficiencies
  • Regulatory compliance gaps
  • Design improvements for safer and more reliable systems

Incorporating HAZOP studies early in project development and periodically throughout a system’s lifecycle ensures that risks are addressed before they evolve into real-world problems. At BM Process, our focus on safety and innovation drives us to apply HAZOP methodology across various industrial sectors, including the automotive industry and tank storage facilities. These sectors often involve volatile materials, high pressures, and complex controls making HAZOP not just useful, but essential.

Smart HAZOP: A Digital Leap in Safety Analysis

We’ve taken HAZOP to the next level through the development of our Smart HAZOP framework. This digital solution enhances the traditional review process with:

  • Improved documentation and traceability
  • Real-time collaboration between stakeholders
  • Automation of repetitive tasks for efficiency
  • Better alignment with compliance and audit requirements

Smart HAZOP represents our commitment to delivering safer, smarter, and more agile process solutions to our clients.

A Culture of Innovation

At BM Process, we believe in constantly evolving our practices. Our culture is rooted in the mindset of “Keep Challenging” rethinking how industrial engineering can be safer, cleaner, and more effective. Whether it’s through partnerships, digital tools, or deep technical expertise, our mission is to push boundaries and elevate safety and performance standards. Want a deeper understanding of global standards and methodologies around HAZOP? The UK Health and Safety Executive (HSE) provides an excellent guide on the principles and implementation of HAZOP studies.
