Final answer:
1) Fireman's carry The easiest method for carrying an unconscious victim alone is the Fireman's carry, as it evenly distributes the victim's weight and allows for balanced transport by the rescuer.
Step-by-step explanation:
The correct answer is option 1) Fireman's carry. This method is typically considered the easiest for one person to carry an unconscious victim because it distributes the victim's weight across the rescuer's shoulders, allowing for a more balanced transport.
Other methods like 2) Two-handed seat carry and 4) Cradle carry require more strength and are less efficient for one rescuer. The 3) Piggyback carry is generally not advisable for an unconscious person, as it does not adequately support the person's body and can be dangerous for both the victim and the rescuer.
In emergency situations, ensuring you have a proper grip and are maintaining your own balance is important, as illustrated in Figure 9.30 where individuals adjust their stances based on the weight they are carrying.
However, always prioritize your safety and the victim's safety by only attempting a carry if you are trained and physically able to do so.
