We offer a range of systematic and comprehensive  methodologies and tools for hazard identification and risk assessment, including:

1. Hazard and Operability Study (HAZOP) / Controls Hazard and Operability Study (CHAZOP) facilitation (eg. using AS/IEC61882).

2. Failure Modes and Effects Analysis (FMEA) / Failure Modes, Effects and Criticality Analysis (FMECA) facilitation (eg. using MIL-STD-1629A or IEC60812).

3. Workplace Risk Assessment and Control (WRAC) / Job Safety Analysis (JSA) / Safe Work Methods Statements (SWMS).

4. Preliminary Hazard Analysis (PHA).

5. Bowtie Analysis (BTA).


“The report concluded (in part) that the following factors contributed to the explosion, fire and loss of gas supply....the failure to conduct a HAZOP study or to carry out any other adequate procedures for the identification of hazards in Gas Plant 1 (GP1) where GP905 was located”.
