The BowTie Risk Assessment is a diagram method that can be used to analyse and demonstrate causal relationships in high-risk scenarios. The diagram is shaped like a Bow-Tie, creating a clear differentiation between proactive and reactive risk management.Continue Reading

Quantitative Risk Assessment (QRA) is summarised in these steps: Hazard Identification (HAZID), to determine hazard and categorisation of MAH Release Frequency Analysis, to calculate the total release frequency for all release scenarios through part counts Consequence Modelling, to model the consequences (JF, FF, PF, EX) Event Tree Analysis, to determine the potential end event likelihood...Continue Reading

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...Continue Reading

Technical Risk Management Tools include Hazard Identification (HAZID), Hazard and Operability Study (HAZOP), Consequence Modelling, Quantitative Risk Assessment (QRA), Layers of Protection Analysis (LOPA), Safety Integrity Level (SIL) Analysis, Failure Mode and Effects Analysis (FMEA) and societal risk (FN Curves).Continue Reading

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.Continue Reading

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.Continue Reading

There are 3 main types of Risk Assessment tools, namely qualitative i.e. using matrices and hazard identification (HAZID) techniques featuring guidewords, semi-quantitative i.e. where word descriptors are associated with numerical ratings and Quantitative Risk Assessment (QRA) which is based on detailed consequence modelling and frequency analysis.Continue Reading

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

Elements of risk assessments are: Identify Hazard Assess Hazard Control Risks Review RiskContinue Reading

A fire alarm system warns people when smoke, fire, carbon monoxide or other fire-related emergencies are detected. These alarms may be activated automatically from smoke detectors, and heat detectors or may also be activated via manual fire alarm activation devices.Continue Reading
