What can I do with RISKCURVES

RISKCURVES is an advanced Quantitative Risk Assessment (QRA) software designed to evaluate risks associated with hazardous substances in industrial settings, such as chemical plants and petrochemical facilities. It integrates with EFFECTS to provide comprehensive risk analysis capabilities. Here is a detailed look at the types of risks it calculates and the studies it supports:

Computed types of risks

Individual Risk (IR)

• Location-Specific Individual Risk (LSIR): Evaluates the risk of fatality for an individual present at a specific location for a year. This helps identify high-risk areas within a facility or its surrounding environment.

• Individual Risk per Annum (IRPA): Calculates the annual risk of fatality for an individual based on their exposure to various hazards throughout the year, incorporating presence factors and protection measures to provide a comprehensive measure of personal risk.

• Risk Transect: Analyzes risk along a transect or path, identifying variations in risk levels across different areas, which is useful for planning and mitigation.

Societal Risk (SR)

• fN Curves: Graphs showing the frequency of incidents causing 'N' fatalities. They help understand the potential impact on society and assess the acceptability of risks based on societal risk criteria.

• Societal Risk Maps: Visual representations of societal risks over a geographical area, aiding in urban planning and emergency response planning.

Consequence risk (CR)

Assesses probabilities of surpassing critical thresholds (such as pressure levels, heat radiation, toxic concentrations, or flammability limits) for strategic facility siting and injury risk evaluation, presented as iso-curves.

Consequence Analysis

Incorporating EFFECTS consequence models allows RISKCURVES to perform calculations of physical effects and integrate them into risk analysis:

• Toxic Dispersion: Simulates the spread of toxic substances in the air following a release, assessing the impact on human health and the environment

• Fire and Explosion Risks: Includes scenarios like pool fires, jet fires, flash fires, and vapour cloud explosions, evaluating potential damage to facilities and surrounding areas.

Integration and usability

• Stationary and transportation equipment: Used for risk assessment in both stationary applications and the transport of hazardous materials along specified routes.

• Analysis points: Define specific locations within the facility or surrounding area for detailed risk assessment, helping to identify key areas of concern and optimize safety measures.

• Multiple calculation sets: Create and manage multiple sets of calculations, applying identical parameters and conditions across various scenarios.

• Imported calculations: Handle large QRAs by importing calculations from RISKCURVES project files, enabling the separation of large projects into smaller, manageable sets that can be combined into one file.

• Imported footprints: Import consequence footprints or spatial data from other sources or software, representing the extent of hazardous substance releases or impact areas, enhancing flexibility and integration of existing analyses.

• Cumulation sets: Useful for analyzing the contribution of specific subsets of scenarios, such as only flammable scenarios, or for combining multiple calculation sets after importing calculations.

• Comparison sets: Compare different risk scenarios, enhancing understanding of how various factors influence overall risk. This is essential for validating changes in population or risk situations and is crucial for decision-making in safety management and urban planning.

RISKCURVES provides comprehensive support for a wide range of safety studies, ensuring that risk assessments are thorough, accurate, and actionable. By integrating with EFFECTS, it offers robust tools for managing industrial risks, contributing to safer operations and regulatory compliance.
