What is a HAZID?

A Hazard Identification is a systematic and thorough method for ensuring that all significant hazards are considered and all potential accident triggering events are identified. The study identifies hazards from:

  • Previous operational experience
  • Effect of failure of equipment designed to protect, detect or mitigate hazards
  • Human error

What are process risk assessments?

Most international health and safety law requires risk assessments to be carried out to ensure and maintain explosion and fire safety measures in all facilities and the workplace.

Risk assessment forms can generally be grouped into two distinct categories: 1) Are we doing enough? 2) Do we need to do more?

Risk assessments are, in effect, a health and safety management tool that can help to identify potential risks or weaknesses to primary designs, systems or the working environment itself.



Our HAZIDs and process risk assessments include:

Sigma HSE’s policy and management procedures for conducting either HAZIDs or process safety risk assessments are based on the following principles:

  • All new and existing processes, within scope of the project, are screened to identify potential hazards and risks
  • Are developed to either eliminate the hazard or reduce associated risk of harm
  • Completion of actions are tracked and led by an individual experienced in carrying out process hazard reviews

Frequently asked questions

How is a HAZID used?

The HAZID is used to identify all potential hazards including major accident hazards. This is followed by the a subsequent qualitative hazard ranking of risk posed by any potential hazards.

The HAZID is recorded using a purpose designed spreadsheet which records the process hazards; control, preventative and mitigation safeguards; and any actions identified during the HAZID.

What kind of risk assessments can Sigma-HSE complete for me?

Our specialist consultants have years of risk assessment experience and are trained to carry out a range of risk assessment methodologies such as HAZOP, HAZID, LOPA, OBRA and QRA.

European and non-European health, safety and environmental work regulations require risk assessments to be undertaken at regular intervals to ensure and maintain workplace safety.

Although there are multiple tools and methodologies available, workplace risk assessments should accurately assess risks, identify hazards and clarify decision-based outputs.

We implement risk assessments in a holistic way to cover employees and non-employees across European facilities and non-European sites.
