If the sternal attachment is used for fall arrest, the competent person evaluating the application should take measures to ensure
that a fall can occur feet first. This may include limiting the allowable free fall distance. It may be possible for a sternal attachment
incorporated into an adjustable style chest strap to cause the chest strap to slide up and possibly choke the user during a fall,
extraction, suspension, etc. The competent person should consider FBH models with a fixed sternal attachment for these
applications.
Frontal -
The frontal attachment serves as a ladder climbing connection for guided type fall arresters where there is no chance to
fall in a direction other than feet first or may be used for work positioning. Supporting the user, post fall or during work positioning,
by the frontal attachment will result in a sitting body position with the upper torso upright with weight concentrated on the thighs
and buttocks. When supported by the frontal attachment the design of the FBH shall direct load directly around the thighs and
under the buttocks by means of the sub-pelvic strap.
If the frontal attachment is used for fall arrest, the competent person evaluating the application should take measures to ensure
that a fall can only occur feet first. This may include limiting the allowable free fall distance.
Shoulder -
The shoulder attachment elements shall be used as a pair and are an acceptable attachment for rescue and entry/
retrieval. The shoulder attachment elements shall not be used for fall arrest. It is recommended that the shoulder attachment
elements be used in conjunction with a yoke which incorporates a spreader element to keep the FBH shoulder straps separate.
Waist, Rear -
The waist, rear attachment shall be used solely for travel restraint. The waist, rear attachment element shall not
be used for fall arrest. Under no circumstances is it acceptable to use the waist, rear attachment for purposes other than travel
restraint. The waist, rear attachment shall only be subjected to minimal loading through the waist of the user and shall never be
used to support the full weight of the user.
Hip -
The hip attachment elements shall be used as a pair and shall be used solely for work positioning. The hip attachment
elements shall not be used for fall arrest. Hip attachments are often used for work positioning by arborists, utility workers
climbing poles and construction workers tying rebar and climbing on form walls. Users are cautioned against using the hip
attachment elements (or any other rigid point on the FBH) to store the unused end of a fall arrest lanyard as this may cause a
tripping hazard or, in the case of multiple leg lanyards, could cause adverse loading to the FBH and the wearer through the
unused portion of the lanyard.
Suspension Seat -
The suspension seat attachment elements shall be used as a pair and shall be used solely for work
positioning. The suspension seat attachment elements shall not be used for fall arrest. Suspension seat attachments are often
used for prolonged work activities where the user is suspended allowing the user to sit on the suspension seat formed between
the two attachment elements. An example of this use would be window washers on large buildings.
