ELECTRICAL SAFE WORK PRACTICESELECTRICAL SAFE WORK PRACTICESI.

PURPOSEThis program provides guidelines for safeguarding personnel and property from electrical hazards presented by energizedor potentially energized exposed electrical components.
II. SCOPE
This program covers all work activities on or near energized parts. Examples may include but are not limited to working onelectrical equipment related to elevator machine rooms, controllers, motors, power panels, relays, escalators, anddisconnects.
III. DEFINITIONS
a. Accessible (as applied to equipment) – Admitting close approach; not guarded by locked doors, elevation, orother effective means.
b. Accessible (as applied to wiring methods) – Capable of being removed or without damaging the building
structure or finish or not permanently closed in by the structure or finish of the building.
Alternative Methods – Equivalent means of protection to lockout tagout when lock out tagout is infeasible orcreates a greater risk to the employee. These methods must provide effective employee protection to prevent theunexpected energization of equipment being serviced.
d. Barricade – A physical obstruction such as tapes, cones, or A-frame-type wood or metal structures intended toprovide a warning about and to limit access to a hazardous area.
c.

e. Barrier – A physical obstruction intended to prevent contact with equipment or live parts or unauthorizedaccess to a work area.
f. Bonding – The permanent joining of metallic parts to form an electrically conductive path that ensures electricalcontinuity and the capacity to conduct safely any current likely to be imposed.
g. Bus – A conductor or group of conductors that serve as a common connection for two or more circuits.
h. Cable Tray System – A cable tray system is a unit or assembly of units or sections, and associated fittings, madeof metal or other noncombustible materials forming a rigid structural system used to support cables. Cable tray
systems include ladders, troughs, channels, solid bottom trays and other similar structures.
i.

Capable of being locked out - An energy isolating device is capable of being locked out if it has a hasp orother means of attachment to which, or through which, a lock can be affixed, or it has a locking mechanism
built into it. Other energy isolating devices are capable of being locked out, if lockout can be achieved without
the need to dismantle, rebuild, or replace the energy isolating device or permanently alter its energy control
capability.

j.

Circuit Breaker – A device designed to open and close a circuit by non-automatic means and to open the circuit
automatically on a predetermined overcurrent without damage to itself when properly applied within its rating.

k.

Conductive – Suitable for carrying electric current.

l.

Conductor, Bare – A conductor having no covering or electrical insulation whatsoever.

m. Conductor, Covered – A conductor encased within material of composition or thickness that is not recognized bythis standard as electrical insulation.
n. Conductor, Insulated – A conductor encased within material of composition and thickness that is recognized bythis standard as electrical insulation.

e. Isolation Verificationi. The qualified personnel entering into the protection boundaries shall don appropriate protection equipment(PPE).
ii. PPE shall be worn continuously throughout all tasks or procedures until equipment is verified to be electricallysafe.
iii. Appropriate voltage-rated equipment shall be used only by a qualified person for such tasks.

f.

Release From Control/Isolation
i. Ensure all personnel are clear of the equipment.
ii. Remove all ground conductors.
iii. Replace all removed equipment components (doors, guards, etc.)
iv. Remove all tools and equipment.
v. Remove lockouts from electrical isolation devices.
vi. Energize system.

ALTERNATE METHODS (SERVICE AND REPAIR)
The primary means for the elimination of electrical hazardous energy is lockout tagout. In the event that it is infeasible, lacks
practicability or is more hazardous to remove the employee from the area to perform LOTO, control circuitry shall be utilized.
The elevator industry poses some unique situations when the elevator is in certain locations in the hoistway or certain
positioning in the pit. Under these conditions it may be impossible, or it may create a greater hazard to exit the work area
to perform LOTO, hence an alternate effective measure of protection must be provided. In addition, ANSI Z244.1 hasprovided guidance in determining the applicability to the use of alternative methods (control circuitry) as an alternative to
LOTO.
For control circuitry to be an acceptable alternate method to lockout tagout a Practicability/Justification Evaluation was
conducted, in conjunction with a hazard risk assessment. These results have been grouped into key categories based on
the tasks. This is the approved process to determine the method of control. There are no acceptable scenarios where
alternative methods can be used for convenience (ANSI B11.1 Analysis – Process for how to employ Control Circuitry.
Alternate effective means needs to have written procedures).

to the National Electric Code and as specified in the Engineering Standards.
A visual inspection and connections tightness of grounds shall be made annually, and additional resistance tests
performed if a ground is suspect.
Temporary Wiring
Temporary wiring shall only be used in areas under construction or repair, for experimental units and for the operationof equipment during emergencies.
Flexible cords and cables with ground wire and conductors preferably smaller than #6 AWG shall be used if necessary.

For example, an individual may have received the necessary training to be consideredon a particular piece of equipment. However, if that same employee were to work on other types of equipment for which
they had not received the necessary training, they would be considered “unqualified” for that other equipment.
All personnel who are required to perform work on electrical devices and systems shall be competent in all safety related
work practices, procedures and requirements that pertain to their respective work assignments. These practices shall
include, but not be limited to, the following.
1. Skills and techniques necessary to distinguish exposed energized components from the other components ofelectrical equipment.

3. Skills and techniques necessary to operate, maintain and service electrical equipment.
4. Knowledge and understanding of the clearance distances corresponding to voltages which personnel may be
exposed to.
5. Proper use of the special precautionary techniques, PPE, insulating and shielding materials, and insulated tools
associated with working on or near exposed components of electrical equipment.
