8.6.3.12.3: Provide blocking under the car or counterweight buffer or both of sufficient strength
and secured in place to withstand the reactions of buffer engagement as described in 8.2.3.
8.6.3.12.4: Provide the month and year the suspension means were first shortened. Appropriate
data shall be recorded on the data tag (see 2.20.2.2.2).

8.6.3.14: Replacements involving SIL Rated Device(s) (See 1.3)
(a) SIL Rated Device (see 1.3) used to satisfy 2.26.4.3.2, 2.26.8.2, 2.26.9.4(b), 2.26.9.5.1(b), or
2.26.9.6.1(b) shall not be affected by other replacement(s) such that the listing/certification is
invalidated.
(b) Where a SIL Rated Device (see 1.3) used to satisfy 2.26.4.3.2, 2.26.8.2, 2.26.9.4(b),
2.26.9.5.1(b), or 2.26.9.6.1(b) is replaced, it shall be considered a replacement only when the
replacement device is the original manufacturer’s listed/certified SIL rated device or the original
manufacturer’s listed/certified SIL rated replacement device; otherwise it shall be considered an
alteration [see 8.7.1.9(d)].
(c) Where a non-SIL Rated Device used to satisfy 2.26.4.3.1, 2.26.8.2, 2.26.9.4(a), 2.26.9.5.1(a),

8.6.11: Special Provisions (Partial)
8.6.11.11 Examination After Shutdown Due to Traction Loss: Where the traction-loss detection
means has been actuated [see 2.20.8.1 and 8.6.1.2.1(g)], the elevator shall not be returned to
service until a physical examination of the drive sheave and suspension means has been
conducted. The elevator shall not be moved until all passengers are out of the elevator and the
elevator is posted out-of-service. In addition to the suspension-means evaluation criteria in
8.11.2.1.3(cc), any suspension-means or drive-sheave condition that would adversely affect the
traction capability of the system (see 2.24.2.3) shall be corrected before returning the elevator to
service. NOTE: See lockout/tagout procedures in Elevator Industry Field Employees’ Safety
Handbook for procedure for removing the elevator from service.
8.6.11.12 Examination After Safety Application: After any safety application on a traction
elevator has occurred, whether due to testing or during normal service, the driving-machine
sheave, all other sheaves, where furnished, and retainers and suspension members shall be
examined throughout their complete length to ensure that all suspension members are properly
seated in their respective sheaves, and that no damage has occurred to sheaves, suspension
members, or retainers. The elevator shall not be returned to service until this physical examination
has been conducted and any repairs made, if necessary.
8.6.11.14 Examination After Shutdown Due to Broken-Suspension-Member Detection
Means: After any application of the broken-suspension-member detection means, whether due to
testing or during normal service, the driving-machine sheave, all other sheaves, where furnished,
and retainers and suspension members shall be examined throughout their complete length to
ensure that all suspension members are properly seated in their respective sheaves, and that no
damage has occurred to sheaves, suspension members, or retainers. The elevator shall not be
returned to service until this physical examination has been conducted and any repairs made, if
necessary. Where a single suspension member has been damaged or broken, the entire
suspension means shall be replaced in accordance with 8.6.3.2.
