What are the principles of risk assessment?

Hazard Identification (HAZID), Assessment of Hazard and Risk, Control of Risk, and Review of the control effectiveness are the principles of Risk Assessment.

What are the benefits of risk assessment?

Some of the benefits of Risk Assessment include maximising safety at minimum cost, helping to aid in decision making, calculating risk exposure and insurance requirements, as well as fulfilling certain legal requirements.

When should you do a risk assessment?

Risk assessment can be conducted following the identification of major accident hazards within the facility. The Risk Assessment can be revisited in the event of a major change such as new machines, substances, and processes that could potentially lead to a major accident.

What is quantitative risk assessment?

Quantitative Risk Assessment (QRA) is a formal and methodical method to estimate the likelihood and consequence of potential hazards that could lead to major accidents. The output from this assessment is expressed quantitatively as a risk to personnel/human, environment, or financial loss. Critical assumptions and risk driving elements are also identified to assess the robustness and validity of the results.

What are the types of quantitative risk assessment?

There are many types of quantitative risk assessment methods available. Here are some of the most used methods: Probabilistic risk assessment Risk-based models Event tree analysis Fault tree analysis Scenario-based analysis Vulnerability assessment Frequency number (FN) curves

How do you do a quantitative risk assessment?

Quantitative risk assessment is summarised in these steps: Hazard Identification, to determine hazard and categorisation of MAH Release Frequency Analysis, to calculate the total release frequency for all release scenario through part counts Consequence Modelling, to model the consequences (JF, FF, PF, EX) Event Tree Analysis, to determine the potential end event likelihood Risk Assessment, to estimate the fire impairment and personnel risk during the loss of containment
