MARITIME – CARGO, LOADING & TABILITY (COMMERCIAL) CALCULATOR
Dangerous Goods Segregation
A precise tool.
What is the Dangerous Goods Segregation & How does it work?
The International Maritime Dangerous Goods (IMDG) Code classifies hazardous cargo into nine primary classes, each with specific handling and segregation requirements.
Segregation distances are defined to prevent dangerous interactions between incompatible classes during stowage, ventilation, and fire scenarios.
The required distance is calculated based on the pair of classes involved and the quantity of each cargo, using the IMDG distance matrix.
d = \theta \times (Q_{1}+Q_{2})
d = segregation distance (m), theta = class‑pair factor, Q_{1}, Q_{2} = quantities (tons)

Frequently Asked Questions
What are the primary classes of dangerous goods in maritime transport?
The International Maritime Dangerous Goods (IMDG) Code classifies hazardous cargo into nine primary classes, including explosives, gases, flammable liquids, etc.
How do segregation distances affect stowage on a ship?
Segregation distances ensure that incompatible classes of dangerous goods are not stored too close to each other, preventing dangerous interactions during transport.
What factors determine the required segregation distance between two types of cargo?
The required distance is calculated based on the pair of classes involved and the quantity of each cargo using the IMDG distance matrix.
Can you explain how to use this calculator for determining segregation distances?
Input the classes of the hazardous goods and their quantities, then the calculator will provide the required segregation distance according to the IMDG Code.
What is the purpose of the IMDG Code in maritime transport?
The IMDG Code provides guidelines for the safe transport of dangerous goods by sea, ensuring compliance with international regulations and minimizing risks.
How often should segregation distances be recalculated during a voyage?
Segregation distances should be recalculated if there are changes in cargo quantities or if the ship’s layout is altered during the voyage.
Are there any exceptions to the segregation requirements for small quantities of dangerous goods?
Yes, certain small quantities of hazardous materials may have reduced segregation requirements as defined by the IMDG Code.
