What is HAZOP analysis?

A Hazard and Operability (HAZOP) analysis looks at all the potential risks in a manufacturing process, identifies problems and finds solutions.

In process manufacturing operations - such as pharmaceutical, chemical, food and similar industries - materials go through multiple stages in the production process where issues can arise. Putting these kinds of materials through industrial processes can lead to unintended consequences if chemicals react in unexpected ways, thermal runaway occurs, or if contaminants enter the process.

The purpose of HAZOP is to investigate and discover any potential weak points where the process could ‘go wrong’ in some manner. Process hazards can arise because of a wide range of factors, but could lead to:

  • Explosions or damage to equipment
  • Injuries to staff who are exposed to toxic or hazardous materials
  • Contamination of foods, medicines, agrochemicals or other products which could severely damage a company’s reputation

Conducting a Hazard and Operability assessment reduces risks to acceptable levels.

Why is Process Hazard Analysis Important?

Conducting a HAZOP assessment of your existing or planned processes provides a wide range of benefits. These include:

Reduce the chances of expensive damage
Conducting a risk analysis of process manufacturing can help identify potential weak points in processes which could cause fires, explosions, corrosion or other problems.

Identify efficiencies and save money
A HAZOP analysis can also help discover inefficiencies in your current process and suggest faster, more effective ways of running your operations.

Improve reputation
Become a trusted brand that takes the safety of customers, employees and the environment seriously.
