Qualitative assessment takes into consideration less tangible factors and is based more on gut reaction than on hard facts and data. Quantitative assessments are based on facts and associated data.Continue Reading

Can be qualitative or quantitative depending on the tools used. HAZID and HAZOP is more qualitative analysis as the objective is more to identify any potential risks, determine the risk reduction measures and prioritise the action/risk reduction measure using the risk matrix. While other tools such as LOPA is more quantitative, a series of data...Continue Reading

The quantitative risk analysis focuses on the major accident risk calculation, including its probability of occurrence and estimation of the magnitude of impact/modelling of the impact from the hazards should it lost of control, as well as identification and recommendation of the safeguard to minimise the risk.Continue Reading

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,...Continue Reading

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) curvesContinue Reading

Qualitative risk assessment uses matrices and hazard identification techniques featuring guidewords while Quantitative Risk Assessment (QRA) is based on detailed consequence modelling and frequency analysis.Continue Reading

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 asses the robustness and validity of...Continue Reading

A statement that clearly describe the risk, causes, potential triggers and consequences.Continue Reading

Every time there is changes to design resulting in new hazards or change in the existing risk assessment outcome.Continue Reading

Avoiding hazards that could lead to a catastrophic event Help to build awareness of risk within the organisation Improved operational efficiency Helps companies to identify risk upfront hence minimise their losses at critical times Maximised the safety and security within the workplace for employees and client Business process improvementContinue Reading
