Ottawa Ontario - The latest version of Rule 112 of the Canadian Railway Operating Rules (CROR) is shown below:

In the application of this rule:
 
(i) Equipment is considered unattended when an employee is not in close enough
        proximity to take effective action to stop the unintentional moving of equipment.
(ii) Physical securement or mechanical devices are:

• hand brakes;
• air brakes;
• derails;
• mechanical emergency devices;
• locomotive equipped with a reset safety control (RSC) with roll-away protection where air pressure is maintained by continuous operation or auto start is provided;
• bowled terrain; and
• if in a yard: retarder, stop-block, wheel chocks and skates.

(iii) High risk locations, as determined by a risk assessment, must be identified in company instructions.
 
(a) When equipment, including a locomotive without an air source, is left unattended on a main track, subdivision track, siding or high risk location, at least the minimum number of hand brakes as indicated in the hand brake chart in (k) must be applied and determined to be sufficient through an effectiveness test described in (e), and at least one additional physical securement or mechanical device must be used. When air brakes are used as an additional means of physical securement:
 
    (i) the air brake system must be charged to ensure proper brake application; and
    (ii) the brake pipe must be fully vented at a service rate or have an emergency
        application and, on freight equipment, the angle cock left open.
    (iii) the equipment may only be left unattended for up to a maximum of two hours.
 
If required to be left longer, an employee must conduct a visual verification to confirm that the equipment remains secure. The verification must confirm the air brake pistons are fully extended and the hand brakes remain applied. This verification must be carried out at consecutive intervals of two hours or less. If any motion is detected during the verification, additional hand brakes must be applied. The results of that verification must be communicated to another employee.
 
(b) When unattended equipment is left coupled to a locomotive with an air source on a main track, subdivision track, siding or high risk location, at least the minimum number of hand brakes as indicated in the hand brake chart in (k) must be applied and determined to be sufficient through an effectiveness test described in (e), and at least one additional physical securement or mechanical device must be used. When air brakes are used as an additional means of physical securement:
 
    (i) the locomotive controlling the air brake system must maintain pressure;
    (ii) the air brake system must be charged to ensure proper brake application and the
        equipment must be left with air brakes applied; and
    (iii) the independent brake must be fully applied.
 
(c) When equipment is left unattended in a yard, at least one physical securement or mechanical device must be utilized.
 
(d) When equipment is left unattended on non-main track, at other than a yard, siding, subdivision track, or high risk location, a sufficient number of hand brakes must be applied and determined sufficient through an effectiveness test described in (e). Special instructions must indicate the minimum hand brake requirements for these locations where equipment is left unattended.
 
(e) When hand brakes are used, an effectiveness test must be performed as follows: release all air brakes and,
 
    (i) allow or cause the slack to adjust. It must be apparent when slack runs in or out,
        that the hand brakes are sufficient to prevent the equipment from moving; or
    (ii) apply sufficient tractive effort to determine that the hand brakes provide sufficient
        force to prevent the equipment from moving when tractive effort is terminated.
 
(f) Hand brakes must be applied on all locomotives in the lead consist of an unattended movement.
 
(g) Application of hand brakes must not be done while equipment is being pulled or shoved.
 
(h) Before leaving equipment at any location, the employee securing such equipment must confirm with another employee the manner in which the equipment has been secured.
 
(i) Exceptional weather situations, such as high winds or other unusual conditions, must be considered and factored into securement decisions. When exceptional weather situations emerge, previously secured equipment may require additional means of securement. Special instructions may contain location specific instructions where extreme weather events are prevalent.
 
(j) When advised that trespasser(s) or emergency responder(s) have been in contact with unattended equipment, the person responsible for the territory must make arrangements to have an employee verify the equipment remains secured without delay.
 
(k) In the application of this chart, the number of hand brakes on locomotives in the lead consist shall not to be included in the number of hand brakes required by the chart.
