Hazard and Risk Assessment

The main purpose of “Hazard and Risk Assessment” (H&RA) is to determine what harmful events might occur with a particular process design.

While IEC 61511 doesn’t provide detailed guidance on which technique should be used for H&RA – since many different techniques are available and some are more suited to particular applications and industries than others – it does require that this activity is subject to the full force of Functional Safety Management.

What =Method can do for you

  • Experienced facilitators for a range of hazard studies, including HazID, HazOp, LOPA, FTA and others.
  • Independent verification when studies are delivered by others.
  • Training and mentoring support for aspiring HazOp Study Leaders.
  • Hazop Team Members training – either as a standalone training course or as part of our preparation for delivering a particular study.
  • Provision and use of work equipment regulation (PUWER) ISO 12100 assessment.

Support for these activities are provided by =Method Process Safety Ltd.
