An automatic fire alarm system detects a fire in its early stages (activated by occupants of the building or by the transmission of fire alarm signals to an alarm-receiving centre), notifies the building occupants that there is a fire emergency and reports the emergency to the first responders.Continue Reading

ALARP principle is to reduce the potential risk of hazard as reasonably practicable so that the risk can be controlled.Continue Reading

The ALARP principle stands for “as low as reasonably practicable”. This principle intends to keep the risk level as low as possible, with the assurance that the ALARP evaluations are thoroughly documented.Continue Reading

Layer of Protection Analysis (LOPA) is an approach to determine the Integrity Levels (ILs) for all identified safeguarding process loops whilst Safety Integrity Level (SIL) is a measure of safety system performance, in terms of probability of failure on demand (PFD).Continue Reading

BowTieXP is the most used Risk Assessment software that is based on the BowTie Method to assess risk. It allows users the ability to visualize complex risks in a clear way while still being detailed.Continue Reading

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
