Objective:
By the end of this module, a trainee will be able to:
Understand the types of emergencies in a petrochemical plant.
Recognize key safety systems (fire, gas detection, alarms, emergency shutdown).
Understand the operator’s role in emergency response.
Apply basic troubleshooting and safe response during abnormal or hazardous events.
Promote safety awareness and preparedness.
Definition:
Emergency Response = actions taken to mitigate risks and protect personnel, environment, and equipmentduring abnormal events.
Safety Systems = equipment and procedures designed to detect hazards, alert personnel, and mitigate incidents.
Importance:
Protects human life and the environment.
Prevents equipment damage and production loss.
Compliance with regulations and plant safety policies.
Operator Role:
Detect and respond quickly to alarms.
Follow emergency procedures and shutdowns.
Communicate clearly with the control room, emergency teams, and management.
Analogy:
Emergency systems = “smoke detectors, sprinklers, and fire alarms in a building.”
Recommended Visuals:

Safety system overview
Fire
Hydrocarbon fire, electrical fire
Activate alarm, ESD if needed, evacuate personnel, use fire extinguishers if trained
Gas Release
Leak of butadiene, hydrogen, or toxic gas
Detect with sensors, notify control room, isolate source, use PPE
Equipment Failure
Pump, compressor, or reactor failure
Monitor alarms, isolate equipment, assist maintenance
Utility Failure
Loss of steam, cooling, instrument air
Notify control room, follow SOP for safe shutdown
Process Upset
Overpressure, high temperature, off-spec product
Respond per process safety SOP, monitor trends, assist in containment
Operator Tips:
Know the location of alarms, fire extinguishers, gas monitors, and emergency exits.
Follow SOPs and emergency drills strictly.
Never panic; prioritize human safety first.
Components:
Fire Detectors & Sensors – detect smoke, flame, or heat.
Fire Extinguishers – portable for small fires.
Sprinklers / Deluge Systems – automated suppression.
Fire Water Pumps & Hydrants – supply water to fire zones.
Operator Role:
Monitor fire alarm panels.
Respond immediately to alarms.
Assist in firefighting only if trained and safe.
Safety Considerations:
Never fight fire without proper PPE.
Evacuate if fire is uncontrollable.
Avoid exposing yourself to toxic smoke or high heat.
Analogy:
Fire system = “home smoke alarm and sprinkler system on a larger scale.”
Components:
Fixed gas detectors for hydrocarbons, H₂, CO, or toxic gases.
Portable gas detectors for field monitoring.
Alarms and interlocks linked to control systems.
Operator Role:
Respond immediately to gas alarms.
Isolate valves or equipment if necessary.
Evacuate personnel from affected area.
Communicate to control room and emergency team.
Safety Considerations:
High flammability or toxicity; always use PPE and SCBA if required.
Avoid ignition sources.
Analogy:
Gas detection = “smoke detector for invisible gas leaks.”
Definition:
ESD = automated or manual system to safely shut down equipment during emergency conditions.
Operator Role:
Know location of ESD buttons/panels.
Initiate ESD if alarms indicate imminent danger.
Verify shutdown sequence completes safely.
Safety Considerations:
ESD may stop pumps, isolate valves, and vent systems; ensure personnel are clear.
Follow SOP to reset system after activation.
Analogy:
ESD = “big red panic button that safely shuts down a factory section.”
Detect & Respond: monitor alarms, abnormal conditions, and trends.
Communicate: inform control room, emergency team, and management.
Isolate: follow SOPs to isolate hazardous equipment or utilities.
Evacuate: move personnel to safe zones if needed.
Document: log the incident, actions taken, and observations for investigation and training.
Analogy:
Operator during emergency = “captain of a ship navigating through a storm.”
Hydrocarbon leak
Butadiene pipeline leak
Stop feed, isolate valves, activate ESD, alert personnel
Fire in process unit
Pump or compressor fire
Activate alarm, use fire suppression if safe, evacuate
High pressure
Reactor or column pressure spike
Reduce feed/heat, verify relief systems, notify control room
Loss of cooling water
Heat exchanger overheating
Reduce load, activate backup cooling, monitor equipment
Gas detector alarm
Hydrogen or toxic gas leak
Evacuate, use PPE/SCBA, notify control room
Operator Tips:
Always prioritize personal safety.
Follow predefined emergency SOPs.
Stay calm and use clear, concise communication.
Name four common emergencies in a petrochemical plant.
What is the operator’s role in fire detection and response?
How should an operator respond to a gas leak?
What is an ESD and when is it used?
Give an analogy for emergency response systems.
What should an operator do if multiple alarms activate simultaneously?

Scenario exercises: simulate gas leak or fire and operator actions
Emergency response and safety systems protect personnel, environment, and equipment.
Operators are the first line of defense, monitoring alarms and responding per SOP.
Fire, gas, leaks, ESD, and other hazards require quick detection, communication, isolation, and safe action.
Training, drills, and adherence to procedures are critical.
Calm, systematic response ensures safety and minimizes process disruption.
