Transcript Recognize electrical hazards that require work practices addressed

ELECTRICAL SAFETY
OSHA requires that electrical equipment be approved for
use and be free from recognized hazards.
OSHA also requires work practice training for all
employees working with electrical equipment.
The applicable OSHA regulations for electrical safety are
contained in 29 CFR 1910.303, 304, 307, 332, 334, and 335.

Training
Employees will be trained to:
Recognize electrical hazards that require work
practices addressed (or, possibly, not addressed)
by OSHA regulations and to seek appropriate help
when such hazards are identified.
Verify that electrical equipment is approved for use and
free of hazards.
Be familiar with the safety-related work practices needed
to perform their jobs.

PROGRAM
Qualified Persons
Only Qualified Persons can enter high voltage areas.
A qualified person is an electrician or electrical worker who
has undergone training to work on live parts or circuits.
Additional training is required for Qualified Persons,
including identifying live parts, determining voltage, and
determining the clearance distances needed to work safely
near live parts.

Approved for Use
For electrical devices and parts, “approved for use” means
that each device has been approved by a nationally
recognized testing laboratory (such as Underwriters
Laboratory) for the intended application.
For installed systems, “approved for use” means that the
system as a whole meets the national electrical code and has
been approved by an agency responsible for enforcement of
the National Electric Code (“NEC”).

Verify Electrical Equipment is
Approved for Use
All equipment must be approved for use by a nationally
recognized testing laboratory.
Equipment should be used only in the manner intended.
Equipment intended for use in a hazardous location should
be rated intrinsically safe for the location.

Employee Responsibilities
Verify that electrical distribution system (if used by Environ
employee) meets the NEC
Ensure that new equipment is approved for the intended use.
Inspect equipment to identify hazards.
Report recognized hazards/dangers to the Host Facility
and/or Project Manager.

Do Not Attempt Repairs
Employees should not attempt to repair
electrical equipment themselves.
Repairs should only be made by Qualified
Persons.

Recognized electrical hazards
Recognized electrical hazards are hazards that
could cause harm to employees, such as:
Bare conductors
Overloaded circuits, outlets, or extension cords
Underground or overhead power cables or wires
Live parts
Working too closely to high voltage or
unrestricted access to high voltage
Using electrical devices in wet or damp locations
Open outlets
Exposed wiring

Cord and plug applications
A ground fault circuit interrupter (GFCI) must
be installed between the equipment and the
electrical source at all times.

Project Manager Responsibilities
Ensure that all employees have been trained for the
electrical hazards that they may encounter at job
sites.
Implement work practices when required
(lock-out/tag-out/try-out).

Work Practices
OSHA requires that work practices be
developed for:
Locking out and tagging out electrical equipment
Working with live parts
Working with or near high voltage
Selecting and using electrical protective equipment

Lock out/Tag out
OSHA standards require that all energized equipment be
de-energized prior to beginning work.
Standards cover servicing and maintenance of
machines when unexpected startup or release of stored
energy could cause injury.
Standard applies to control of energy during servicing
and/or maintenance.
NOTE: servicing/maintenance during normal production operations is
covered if an employee is required to remove or bypass a guard or if an
employee must place his/her body into danger zone.

Summary
Because Facility employees are generally not expected to
often be working on or with electrical equipment while
visiting a site, this training is designed to provide an
overview of the potential hazards associated with working
with or around electrical equipment.
