CHAPTER 1.4 – SECURITY PROVISIONS

Security is a critical aspect of dangerous goods transport. While the primary objective of the IMDG Code is to prevent accidents and protect life, property, and the marine environment, an additional responsibility lies in preventing intentional misuse of dangerous goods. Materials that are hazardous by nature can become significantly more dangerous if used unlawfully. Therefore, this chapter establishes security requirements to minimize the risk that dangerous goods are diverted, stolen, tampered with, or used for harmful purposes.

1.4.1 Purpose

The purpose of the security provisions is to prevent dangerous goods from being used in acts of terrorism, sabotage, criminal activity, or any unauthorized operation that could endanger human life, disrupt transportation systems, or damage the environment.

Dangerous goods contain properties that, if deliberately exploited, can produce catastrophic outcomes. For example:

• Explosives can be detonated,

• Toxic gases can be released,

• Radioactive materials can be misappropriated,

• Flammable liquids can fuel fire or explosions.

Therefore, security is not solely a protective measure; it is a deterrent strategy, ensuring dangerous goods remain under authorized control at all times throughout transport.

These provisions reinforce:

• Access control, to ensure only authorized personnel handle DG,

• Awareness, so workers can identify suspicious situations,

• Preparedness, enabling rapid action if a security risk is detected.

1.4.2 High Consequence Dangerous Goods (DG)

Certain dangerous goods pose a heightened security risk due to their destructive potential if misused. These substances require enhanced security controls beyond standard measures.

Examples of High Consequence DG include:

These items are considered high consequence because unauthorized access may result not only in property damage, but major loss of life, disruption of commerce, or environmental contamination.

1.4.3 Security Measures

To protect dangerous goods throughout the transport chain, organizations must implement security controls proportional to the level of risk. Measures should be embedded into operational procedures and integrated with existing safety management systems.

a. Background Checks

Personnel who have direct access to high consequence DG should undergo identity verification and screening appropriate to national regulations.
This prevents individuals with malicious intent—or those susceptible to coercion—from obtaining direct physical control over sensitive cargo.

b. Controlled Access Zones

Dangerous goods storage, handling, and transfer areas must be restricted to authorized personnel only.
Examples include:

• Fenced storage yards,

• Secure warehouses,

• Monitored port facilities,

• Locked containers and sealed transport units.

Access points should be supervised through:

• Security personnel,

• Electronic identification systems,

• CCTV monitoring where required.

c. Cargo Inventory Control

All movements of dangerous goods must be tracked, documented, and verified, from receipt to loading and discharge.
Controls include:

• Package counting and reconciliation,

• Seal verification,

• Inventory logs,

• Real-time tracking for certain high consequence materials.

The goal is to identify missing, tampered, or diverted cargo immediately.

d. Ship Security Plan Integration (ISPS Code)

Security measures for dangerous goods must be aligned with the International Ship and Port Facility Security (ISPS) Code.
This integration ensures:

• Ship Security Officers (SSO) maintain awareness of DG risks,

• Access control procedures match cargo sensitivity,

• Emergency response accounts for both safety and security hazards.

Dangerous goods security is therefore embedded in maritime security policy, not treated as a separate discipline.

1.4.4 Emergency Notification

If suspicious behavior, attempted interference, or confirmed theft involving dangerous goods occurs, it must be reported without delay to:

• Competent Authority (national body responsible for DG regulation),

• Flag State, if onboard a vessel,

• Port Authority, if within a terminal or loading facility,

• Company Security Officer (CSO) under ISPS Code requirements.

Examples of reportable events:

• Unauthorized attempt to access DG storage,

• Missing packages or unexplained seal breaks,

• Tampering with labels or documents,

• Suspicious surveillance of DG handling areas.

Timely notification ensures rapid investigation and prevents escalation of potential threats.
Failure to report security breaches may be considered non-compliance and expose organizations to legal consequences.
