A report published on 5 October 2026 by reports defines the maritime concept of an "enclosed space" and frames it in the context of safety and risk management for shipboard operations.
What the report defines
The item opens by setting out a working definition: an enclosed space is any compartment that can contain a hazardous atmosphere or lack sufficient oxygen, and which has restricted access, poor ventilation or was not intended for continuous human occupation. This definition is presented as the foundation for subsequent discussion in the report.
The report lists the types of hazards that the phrase "enclosed space" is intended to capture and stresses that the classification rests on physical and atmospheric characteristics rather than solely on location or label.
Examples and operational context
To illustrate the scope, the report cites a range of shipboard areas that meet the definition. These include cargo holds, ballast tanks and fuel tanks, pump rooms, cofferdams, bilge spaces, chain lockers, various void spaces and engine crankcases. The examples show the breadth of environments to which the term can apply.
The report’s title, Enclosed Spaces-Safety and Risk Management, signals that its focus extends beyond definition to the management of the hazards such spaces present. Sources published the piece on 5 October 2026, making the date part of the public record for the item.
The report emphasises that the presence of an unsafe atmosphere or an oxygen deficit, combined with constrained access and inadequate ventilation, is the defining concern. Those three features are highlighted as central to why these compartments warrant particular attention within shipboard safety regimes.
Recognising the variety of enclosed spaces aboard modern vessels, the report draws attention to the operational challenge of identifying such spaces on different ship types. The listed examples underline that potential danger can be found across cargo, machinery and utility areas, reflecting a consistent hazard profile regardless of a space’s primary function.
reports presents the item as an introduction to the subject, establishing the term and mapping the principal categories of space likely to be considered enclosed under the definition.
