When the requestor occurs in the water or at sea, the rescuer pulls the loading handle 32 and retreats and determines the separation distance with the requestor, and then pulls the trigger 90.

In the aiming process, the tip of the launch tube 11 should be inclined toward the sky so that the projectile 200 can fly along the parabolic trajectory. At this time, the rescuer determines the inclination angle in consideration of the separation distance of the requester and the pressure inside the vaporization cylinder 40, and then adjusts the inclination angle of the lifesaving launcher while looking at the scale of the angle indicator 70 coupled to one side of the case 80.
