In terms of tanker safety, what is a "blast"?

The term "blast" in the context of tanker safety refers to a sudden release of vapor that can ignite and lead to an explosion. This phenomenon is particularly critical in tanker operations where flammable vapors are present, especially during loading and unloading procedures. When vapors escape rapidly and find an ignition source, the resulting blast can cause significant damage, posing a severe risk to personnel, vessels, and the environment.

Understanding this aspect of tanker safety is vital for crews tasked with operations involving highly volatile substances. A thorough comprehension of the potential for a vapor blast helps ensure that safety protocols are in place to minimize risks, such as maintaining proper ventilation, monitoring vapor concentrations, and adhering to safe loading practices.
