Examples of harnesses with an A (fall-arrest) point:
Particular case:
The choice of harness attachment point has an effect on:
- Working comfort (ASAP and absorber in front or behind the worker)
- Worker autonomy (can the worker install the ASAP themselves, or not)
- The post-fall suspension position, especially if unconsciousness occurs
Ventral (sit 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
Sternal
- 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
Dorsal
- 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
