PART 7: PROVISIONS CONCERNING TRANSPORT OPERATIONS

Part 7 focuses on how dangerous goods are loaded, stored, segregated, transported, and managed during emergencies.

---

Chapter 7.1 – General Stowage Provisions

Principles:

• Load distribution to maintain ship stability

• Accessibility for observation & firefighting

• Protection from heat sources, vibration, moisture

• Securing cargo to prevent movement in rough seas

Training objective:
Stowage errors can make safe cargo dangerous—correct planning prevents escalating incidents.

---

Chapter 7.2 – General Segregation Provisions

Segregation prevents dangerous chemical reactions between incompatible substances.

Key concepts:

• “Away from”, “separated from”, “separated by a complete compartment”

• Avoid mixing acids with alkalis, oxidizers with fuels, flammables with corrosives

Training objective:
Understand segregation tables and apply them to container stowage planning.

---

Chapter 7.3 – Packing & Use of Cargo Transport Units (CTUs)

Defines safe CTU loading practices:

• Load securing to prevent shifting

• Ventilation for gases & self-heating goods

• Elimination of empty space to avoid impact damage

• Inspection prior to sealing

Training objective:
Improper packing is a leading cause of maritime container incidents—correct packing preserves safety.

---

Chapter 7.4 – Stowage & Segregation on Container-ships

Container-ships use container stacks and cell guides.

Requirements:

• Deck vs. hold placement based on hazard

• Emergency access zones

• Firefighting system access

Training objective:
Crew must know where hazardous materials are located for effective emergency intervention.

---

Chapter 7.5 – Stowage & Segregation on Ro-Ro Ships

Ro-Ro ships have vehicle decks accessible by ramps.

Controls:

• Securing wheeled units

• Ventilation to avoid gas accumulation

• Avoiding flammable goods near engines or exhausts

Training objective:
Ro-ro environments increase fire spread risk—ventilation and access are critical.

---

Chapter 7.6 – Stowage & Segregation on General Cargo Ships

These ships have holds, tween decks, and cargo gear.

Key points:

• Manual segregation planning

• Use of dunnage, liners, separation bulkheads

• Protection from contamination and moisture

Training objective:
More variability means planners must evaluate each cargo individually.

---

Chapter 7.7 – Shipborne Barges on Barge-Carrying Ships

Stowage involves large modular units (barges) loaded onto mother ships.

Note:

• Additional structural securing

• Fire response limited—placement is critical

Training objective:
Understand risk of difficult access during emergencies.

---

Chapter 7.8 – Incident Response & Fire Precautions

Covers operational controls for emergencies involving DG.

Includes:

• Firefighting strategies linked to hazard class

• Use of EmS & MFAG

• Isolation and cooling techniques

• Communication flow during incidents

Training objective:
Crew must know how to respond safely, when to fight, and when to isolate & evacuate.

---

Chapter 7.9 – Exemptions, Approvals & Certificates

Certain transports require official authorization.

Examples:

• Prototype materials

• Special packaging

• High-risk radioactive shipments

• Exemptions under emergency circumstances

Training objective:
Know when competent authority approval is mandatory and how documentation supports safe transport.
