(a) steel lintels above openings not more than 2 m wide in loadbearing walls and not more than 3 m wide in non-loadbearing walls,
(b) steel lintels above openings more than 2 m wide in loadbearing walls and more than 3 m wide in non-loadbearing walls, provided the lintels are supported at intervals of not more than 2 m by structural members with the required fire-resistance rating,
(c) the bottom flanges of shelf angles and plates that are not a part of the structural frame,
(d) steel members for framework around elevator hoistway doorways, steel for the support of elevator and dumbwaiter guides, counterweights and other similar equipment, that are entirely enclosed in a hoistway and are not a part of the structural frame of the building,

(i) not less than 1 m away from any unprotected opening in an exterior wall, or
(ii) shielded from heat radiation in the event of a fire within the building by construction that will provide the same degree of protection that would be necessary if the member was located inside the building, with the protection extending on either side of the member a distance equal to the projection of the member from the face of the wall.
