The safety device includes an airbag (1), an ignition portion (3, 31), a first flow path (4) configured to guide hydrogen to the ignition portion (3, 31) from a first container (20) filled with hydrogen, a first opening and closing portion (B1) disposed in the first flow path (4) and switchable between a closed state and an opened state, an introduction section (6, 6A) introducing oxygen into the first flow path (4), and a water vapor flow path (5) configured to guide water vapor generated by the ignition portion (3, 31) to the airbag (1). Before inflating and deploying the airbag (1), the first opening and closing portion (B1) is in the closed state, and at the time of inflating and deploying the airbag (1), the first opening and closing portion (B1) is temporarily switched from the closed state to the opened state to supply an appropriate volume of hydrogen to the ignition portion (3, 31).
