Module 14 – Safety, Fire & Emergency Response

Objective:
By the end of this module, a trainee will be able to:

1. Understand common hazards in a butadiene/petrochemical plant.

2. Recognize fire and explosion risks.

3. Apply safety measures and prevention strategies.

4. Respond appropriately to emergency situations.

5. Follow emergency shutdown procedures and communicate effectively.

14.1 – Introduction to Safety

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”

14.2 – Common Hazards in Butadiene Plants

• 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.

14.3 – Fire Prevention & Control

Prevention:

1. Control ignition sources: no smoking, spark avoidance.

2. Regular inspection of valves, lines, and equipment.

3. Maintain good housekeeping: remove flammable debris.

4. Follow hot work permit procedures.

5. 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.”

14.4 – Emergency Response Principles

Immediate Actions:

1. Raise alarm and notify control room.

2. Evacuate personnel if required.

3. Isolate affected equipment (valves, pumps) safely.

4. Activate emergency shutdown (ESD) if needed.

5. 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”

14.5 – Emergency Shutdown (ESD)

Purpose:

• Rapidly bring plant to safe state during critical conditions (fire, leak, overpressure).

General Steps (Conceptual):

1. Detect hazard (alarm, visual).

2. Initiate ESD (manual or automated).

3. Close critical valves and stop feed.

4. Shut down utilities if needed (steam, instrument air, electricity).

5. Isolate reactors or storage tanks.

6. 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.”

14.6 – Operator Safety Practices

1. Personal Protective Equipment (PPE): helmet, flame-resistant clothing, gloves, goggles, respirator.

2. Gas detection & monitoring: portable and fixed gas detectors.

3. Work permits: hot work, confined space entry, lockout/tagout.

4. Communication: radios, alarms, logs, shift handover.

5. Drills & training: participate in fire and spill drills regularly.

14.7 – Quiz / Knowledge Check

1. Name three common hazards in a butadiene plant.

2. What is the first action when detecting a fire?

3. Name two ways to prevent fire in a petrochemical plant.

4. What is the purpose of ESD?

5. List at least three PPE items critical for operators.

6. Give an analogy for emergency response.

14.9 – Summary & Key Takeaways

1. Safety is the highest priority in any petrochemical operation.

2. Hazards include flammable gases, fire, pressure, toxic exposure, and mechanical risks.

3. Operators prevent incidents via housekeeping, inspections, SOPs, and PPE.

4. Emergency response involves early detection, alarms, isolation, ESD, and evacuation.

5. Regular drills and communication ensure effective handling of emergencies.
