Which risk increases when a zeppelin’s hydrogen vents inadequately during rapid ascent?

💡 Explanation

Flammability increases because rapid ascent expands internal volume, causing vented hydrogen to rapidly mix with atmospheric oxygen beyond upper flammability limit via rapid diffusion, therefore explosion risk is the correct answer, rather than simple 'fire' which has lower concentrations
