How can the presence of vapors in cargo tanks affect safety?

The presence of vapors in cargo tanks is particularly concerning due to their potential flammability and explosiveness. When volatile substances evaporate from a liquid cargo, they create a mixture of vapor and air that can ignite if exposed to a sufficient source of heat or a spark. This creates a significant safety risk, as the combination of flammable vapors and the right conditions can lead to a fire or explosion, endangering the vessel, crew, and the environment.

Moreover, managing these vapors is essential in tanker operations to ensure the safety of ship personnel and to comply with safety regulations. Regular monitoring and proper ventilation are crucial to mitigate the risks associated with these vapors. Therefore, understanding the flammable nature of vapors is fundamental to maintaining safety on board tankers.
