ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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 , 304, 307, 332, 334, and 335.

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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.

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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.

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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”).

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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.

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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.

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M Do Not Attempt Repairs Employees should not attempt to repair electrical equipment themselves. Repairs should only be made by Qualified Persons.

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M Cord and plug applications A ground fault circuit interrupter (GFCI) must be installed between the equipment and the electrical source at all times.

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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).

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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.

ELECTRICAL SAFETY / E N V I R O N H & S T R A I N I N G P R O G R A M 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.
