Which of the following is a primary blast effect?

Primary blast effects are injuries caused directly by the blast overpressure—the pressure surge from the explosion itself. This wave presses on air-filled organs, can rupture eardrums, and cause lung and internal injuries even if there isn’t any debris or a hard impact involved. The other categories describe injuries from different mechanisms: secondary effects come from flying debris and shrapnel, tertiary effects from the body being thrown and striking objects, and quinary effects from additional factors like burns or toxic exposures added by the explosion. So, the description that matches injuries produced directly by the blast wave is the correct, primary blast effect.
