What are the best design practices to minimize explosions and fires in facilities?

Quantitative Risk Assessment (QRA) is a methodical process used to evaluate the likelihood of a particular event occurring and the potential consequences if it does. This type of analysis is typically used in fields such as engineering, finance, insurance, and environmental science to identify and manage potential risks. QRA involves the use of mathematical models and statistical analysis to estimate the probability and severity of a given risk. We can use this risk analysis to have a safe distances between equipment to avoid explosion consequences, determine which asset or equipment required blasting walls during design.

Hazard Identification and Risk Analysis (HIRA) is a collective term that encompasses all activities involved in identifying hazards and evaluating risk at facilities, throughout their life cycle, to make certain that risks to employees, the public, or the environment are consistently controlled within the organization’s risk tolerance. These studies typically address three main risk questions to a level of detail commensurate with analysis objectives, life cycle stage, available information, and resources. The three main risk questions are: Hazard – What can go wrong? Consequences – How bad could it be? Likelihood – How often might it happen?

In my experience, I saw analyzing the hazard, understanding the process, listing the major accidents hazards (fire hazard analysis) is the key start for all downstream Hazards consequences analysis either qualitatively or quantitatively. Building this knowledge will help is studying it as sometimes the less time invested on this subject using the proper experts, the less reality about the scenarios and data in to the softwares useful.

1.Proper Ventilation: Ensure adequate ventilation to disperse flammable gases and prevent them from accumulating to dangerous levels. 2. Fire Suppression Systems: Install fire suppression systems such as sprinklers, fire extinguishers, and fire blankets to quickly contain and extinguish fires. 3. Safety Signage and Training 4. Proper Storage: 5. Electrical Safety 6. Chemical Handling Procedures 7. Regular Maintenance 8. Emergency Response Plan 9. Risk Assessment 10. Compliance with Regulations By incorporating these design practices, facilities can significantly reduce the risk of explosions and fires, thereby promoting a safer working environment for employees and minimizing property damage.

Plant layout is a challenging issue since project start, as there are several ways to layout the equipment 1- based on predefined requirements in the codes and standards. 2- based on initial calculations of fire protection water demand to limit the plant fire protection like what is there in Aramco. However, the early plant layout should be cross checked based on fire and explosion model analysis to check the validity of the layout and in case there could be improvement needs to be made. All these efforts shall be aligned with maintenance and access requirements as well as constructibility.

The layout and spacing of a facility help to arrange equipment, storage areas, and workspaces, designers can reduce the risk of hazardous materials coming into contact with ignition sources or each other. Adequate spacing between equipment and storage areas helps prevent potential fire spread and allows for easier access during emergencies. Additionally, considering factors such as escape routes, emergency exits, and access for emergency responders enhances overall safety. Overall, thoughtful layout and spacing design contribute significantly to mitigating the potential for explosions and fires in facilities.

A fire and gas safety system adds a mitigating layer of protection to an emergency shutdown system, should an event occur. Fire and gas safety systems reduce the severity of an identified event such as when gas, smoke, flame, or heat is detected, by raising an alarm and initiating further suppression and isolation systems, to contain the threat.

Fire and gas detection systems are essential components of facility safety measures. These systems continuously monitor for the presence of flammable gases and smoke, providing early warning of potential fire hazards. By promptly detecting the presence of fire or hazardous gases, these systems allow for swift response actions, such as activating fire suppression systems or initiating evacuation procedures. Effective fire and gas detection systems with appropriate protection measures, facility designers can enhance overall safety and mitigate the risk of explosions and fires.
