SCOPE AND PURPOSE
This Standard outlines the requirements for, and safe use of ground fault circuit interrupters at Sarnia
Refinery. This standard replaces S.O. #2.009.
ROLES AND RESPONSIBILITIES
Employees and Contractors are accountable to this Standard and to follow operating
procedures and work practices.
Refinery Leaders are accountable to ensure compliance to this Standard
Refinery Vice President is accountable to approve, maintain and ensure compliance to this
standard.

Operations & Director, Maintenance. Approval will be considered only after completion of a formal
risk assessment. Our Management of Change process will be employed to document mitigating
actions, assign accountabilities and track the abnormal condition. The Management of Change
document must be reviewed and approved by the Director, Operations & Director, Maintenance

RISK CONTROLS
Approved Ground Fault Circuit Interrupters (GFCI’s) are designed to reduce the risk of severe or
fatal electric shocks when using portable electrical equipment in outdoor or wet locations. This
personal protective equipment (PPE) senses when electrical current leaks to ground (i.e. through
a human) and isolates the power at the receptacle within a fraction of a second. GFCI’s shall be
used when operating 120VAC portable electrical devices (e.g. power tools, trouble lights, etc.) in
an outdoor or wet environment. It is the responsibility of the user to ensure that the GFCI is in
good working order and tested prior to each use. When required, portable GFCI sets may be
obtained from the tool-crib (subject to defined terms on specified contracts). In certain situations,
the Contractor will be responsible for providing GFCI’s as deemed necessary and shall be
installed in one of the three following configurations:
1. When a cheater cord is required, a portable GFCI shall be physically installed between the
cheater cord and the portable electrical device. This will ensure the GFCI is kept within the tested
area of the Hot Work Permit (reference “Explosion Proof Extension Cords, Cheater Cords and
Dog Houses” Standard). As an alternate, a cheater cord containing a built-in GFCI (i.e. an
integrated cheater cord/GFCI assembly) may be used.
2. For outdoor portable explosion-proof equipment, when no cheater cord is required, a portable
explosion-proof GFCI shall be physically installed between the explosion-proof receptacle (source
of power), and the electrical device to be operated. The explosion-proof GFCI shall be located
nearest to the permanently installed explosion-proof receptacle.
3. For general purpose applications, where there is no requirement for a cheater cord, or an
explosion-proof plug, a portable GFCI shall be physically installed between the receptacle (source
of power), and the portable device. The GFCI shall be located nearest to a permanently installed
receptacle. Example - plugging an extension cord into a receptacle inside a building, which
powers a portable electric drill, used outdoors. This would require a GFCI to be inserted between
the wall receptacle and the extension cord plug.
This Standing Order supports the Ontario OHSA regulations for Industrial Establishments
or Construction sites.
