Scope

This document specifies a theoretical calculation method for the ventilation volume of the cargo holds of ships carrying vehicles with internal combustion engines, so as to dilute the polluted air to within the permissible occupational exposure limits.
Appendix A specifies the average values of pollutants emitted by vehicles with internal combustion engines operating in the cargo holds of ships.
Appendix B provides guidelines for achieving good ventilation operations in the cargo holds of ships carrying vehicles with internal combustion engines.
Users of this document are advised that, while meeting the requirements of this document, they should also comply with other statutory requirements, rules, and regulations related to their respective ships. Users may also refer to the International Maritime Organization (IMO) Maritime Safety Committee (MSC) Circular No. 729 (MSC Circ.729) titled "Guidelines and Operational Recommendations for the Design of Ventilation Systems in Roll-on/Roll-off Cargo Holds"1) .
