Plan for emergencies

Adequate planning for an emergency is crucial in creating an effective emergency response plan. It is vital to understand the behaviour and potential consequence of release of hazards, particularly in industries handling hazardous materials such as the chemical and oil and gas industries. When a release of hazardous materials occurs, it is important to have a clear understanding of the possible consequences of release, such as the extent of fire, explosion, and toxic releases. This serves as a critical guide for emergency responders, enabling them to act swiftly and decisively during emergency, thereby enhancing overall safety.

To effectively plan for such incidents, it is crucial that personnel involved in emergency response planning to answer key questions such as:

  • How wide-spread could the impact of the incident be in varying weather conditions?
  • Which areas and population groups are at risk of exposure and for how long?
  • What is the influence of prevailing wind conditions, e.g. day-time versus night-time?

Modelling of detailed hazardous outcomes using Phastâ„¢

Phast is a powerful tool that provides a comprehensive analysis of hazardous outcomes resulting from material releases. Using validated mathematical models, it simulates the behaviour of flammable and toxic substances, offering valuable insights to emergency responders. Its capabilities include determining the location and size of potential fires, explosions, and toxic clouds. Its Geographical Information System (GIS) feature allows users to pinpoint release locations and incorporate additional information, such as location of safety-critical equipment. This visualization aids in planning, effective communication, and collaboration with stakeholders, enhancing overall analysis capabilities for better decision-making.
