(e) The control station shall be supported in a manner that will protect the power-source conductors against strain.
(f) Any control station that might present a hazard to the operator if a ground fault occurs shall be grounded.
28-1.2.9 Loss of Power
Interruption of power to balancers shall not cause a hazardous situation such as loss of control, unintended movement, and unintended direction of travel.
28-1.2.10 Manuals

(a) hazards
(b) warnings that indicate the consequences of not adhering to the warning and methods to avoid the hazards
(C) installation
(d) operation
(c) inspection
(f) testing
(g) lubrication
(h) maintenance

SECTION 28-1.3: INSTALLATION
28-1.3.1 Procedure
(a) rrocedure for balancer installation as recommended by the manufacturer shall he followed.
(b) When balancers are suspended from a trolley, monorail, or bridge and the rated capacity of any of these components is different from that of the halancers, the rated load of the system shall be based on the lowest minimum rated load of any individual component within the system.
28-1.3.2 Support
The supporting structure of the halancers, including trolleys, monorails, crane, or floor supports, shall be designed to withstand the loads and forces imposed by the balancers when operated at their rated load.
28-1.3.3 Location
(a) Balancers shall be installed in locations that will allow sufficient space for the operator to stay clear of the balancer’s load and provide clearances to preclude the operator from being entrapped by the balancer or its load.
(b) Balancers shall not be installed in a hazardous location unless approved by the manufacturer.
28-2.1.1 General
All inspections shall be performed by a designated person. Any deficiencies identified shall be examined and a determination made by a qualified person as to whether they constitute a hazard and, if so, what additional steps need to be taken to address the hazard.
28-2.1.2 Inspection Classifications
(a) Initial Inspection. Prior to initial use, all new, reinstalled, repaired, or altered balancers shall be inspected to verify compliance with the applicable provisions of this Volume.
(b) The inspection procedure for balancers in regular service is divided into two general classifications based upon the intervals at which the inspections should be performed. The intervals, in turn, are dependent upon the nature of the critical components of the balancers and the degree of their exposure to wear, malfunction, or deterioration. The two general classifications are designated as “frequent” and “periodic” with respective intervals between inspections as defined below:
(1) Frequent Inspect foil. A visual and audible examination for which written records are not required.
