The ASAP, as with any fall arrest system, must be connected to the A (fall arrest) attachment point of the harness.

Example of a harness having an A (fall arrest) point:

The choice of harness attachment point influences:

- Work comfort (ASAP and absorber in front or behind the worker)

- Worker autonomy (can the worker install the ASAP themself, or not)

- The post-fall suspension position, especially in case of unconsciousness


Ventral (seat harness without fall arrest point)


- The ventral attachment point is not an A (fall arrest) point

- Risk of inversion if the victim is wearing a pack, or has a heavy object attached to the harness




- Position is more ergonomic when suspended

- Rescuer can easily manage the victim's position


- The ASAP can take up space in front of the user during work




- Clear work space


- Uncomfortable position when suspended: abdomen and airway squeezed if the person is unconscious

- Difficult for rescuer to manage the victim's position
