Objective:
By the end of this module, a trainee will be able to:
Understand common hazards in a butadiene/petrochemical plant.
Recognize fire and explosion risks.
Apply safety measures and prevention strategies.
Respond appropriately to emergency situations.
Follow emergency shutdown procedures and communicate effectively.
Definition:
Safety = measures and practices to protect personnel, equipment, and environment.
Importance:
Petrochemical plants handle flammable, toxic, and high-pressure materials.
Proper safety practice prevents injuries, fatalities, environmental damage, and production loss.
Operator Role:
Follow SOPs, safety rules, and PPE requirements.
Identify hazards early.
Participate in drills and emergency response.
Analogy:
Safety = “seatbelt, helmet, and checking surroundings before driving”
Flammable Gas
Butadiene leaks, hydrogen
Monitor gas detectors, report leaks
Fire/Explosion
Reactor, storage tank
Keep ignition sources away, follow hot work permit
Toxic Exposure
Hydrocarbons, chemical additives
Use respirators, follow exposure limits
Mechanical
Pumps, compressors, moving parts
Maintain guards, report abnormal noise/vibration
Thermal
Hot surfaces, steam
Use PPE, monitor temperature
Pressure
Overpressure in vessels/pipes
Monitor pressure gauges, follow relief system SOPs
Operator Tips:
Always assume hydrocarbon leak = flammable hazard.
Keep escape routes and emergency equipment accessible.
Observe alarms and warning lights promptly.
Prevention:
Control ignition sources: no smoking, spark avoidance.
Regular inspection of valves, lines, and equipment.
Maintain good housekeeping: remove flammable debris.
Follow hot work permit procedures.
Ensure firefighting equipment is functional and accessible.
Fire Fighting Basics (Conceptual):
Fire classification: Class A (solids), B (flammable liquids/gases), C (electrical).
Extinguishers: water, foam, CO2, dry powder depending on class.
Operator Role:
Detect fire early (smoke, alarm).
Activate fire alarms or suppression systems.
Evacuate personnel if necessary.
Coordinate with emergency response team.
Analogy:
Fire prevention = “keeping a candle away from curtains; extinguishing = using correct extinguisher when it starts.”
Immediate Actions:
Raise alarm and notify control room.
Evacuate personnel if required.
Isolate affected equipment (valves, pumps) safely.
Activate emergency shutdown (ESD) if needed.
Follow emergency SOPs for fire, leak, or spill.
Operator Tips:
Know emergency exits and assembly points.
Follow pre-defined communication channels.
Do not attempt heroic action; prioritize safety.
Analogy:
Emergency response = “following fire drill at school: alarm → exit → assembly → report”
Purpose:
Rapidly bring plant to safe state during critical conditions (fire, leak, overpressure).
General Steps (Conceptual):
Detect hazard (alarm, visual).
Initiate ESD (manual or automated).
Close critical valves and stop feed.
Shut down utilities if needed (steam, instrument air, electricity).
Isolate reactors or storage tanks.
Monitor process until safe.
Operator Tips:
Always follow ESD SOP; know which buttons/valves to operate.
Communicate with control room and emergency team.
Ensure personnel safety first.
Analogy:
ESD = “hitting the emergency stop on a conveyor or machine when something goes wrong.”
Personal Protective Equipment (PPE): helmet, flame-resistant clothing, gloves, goggles, respirator.
Gas detection & monitoring: portable and fixed gas detectors.
Work permits: hot work, confined space entry, lockout/tagout.
Communication: radios, alarms, logs, shift handover.
Drills & training: participate in fire and spill drills regularly.

Safety is the highest priority in any petrochemical operation.
Hazards include flammable gases, fire, pressure, toxic exposure, and mechanical risks.
Operators prevent incidents via housekeeping, inspections, SOPs, and PPE.
Emergency response involves early detection, alarms, isolation, ESD, and evacuation.
Regular drills and communication ensure effective handling of emergencies.
