The purpose of our NEC electrical policy
What is to eliminate injuries and accidents associated with work on or near electrical circuits and equipment?
What equipment each authorized employee needs to have to perform LOTO
What is a lock and tag?
Thermal burns including burns from heat generated by an electric arc, and flame burns from materials that catch on fire from heating or ignition by electrical currents or an electric arc flash.
What is an electrical burn?
*Contact burns from being shocked can burn internal tissues while leaving only very small injuries on the outside of the skin.
Type of tools to be used when working on electrical work
What is insulated?
The color insulation you are allowed to use for a Grounding Electrode Conductor.
What is bare, green or green with yellow?
The only type of person that may work on electrical hazards
What is a qualified person?
An employee that is not authorized to perform LOTO, but works in the area where locked, tagged, and energy-controlled devices are present.
What is an affected employee?
Muscle contractions, or a startle reaction, can cause a person to do this
What is fall?
The second most frequently cited OSHA hazard
What is LOTO?
How often extension cords need to be tested
What is once per quarter?
**Note: all new cords need to be tested before use and should be visually inspected before each use thereafter.
Electrical panels need to have a clear space of this distance in front of the access panel
What is 36 inches (3 feet)?
A hidden energy source that is capable of releasing energy suddenly
What is a stored energy source?
Direct contact with exposed energized conductors or circuit parts.
What is electrocution?
*When electrical current travels through our bodies, it can interfere with the normal electrical signals between the brain and our muscles (e.g., heart may stop beating properly, breathing may stop, or muscles may spasm).
What OSHA stands for
What is Occupational Safety and Health Administration?
How often power hand tools need to be tested
What is once per quarter?
*Note: all new tools must be tested before use and should be visually inspected before each use thereafter.
Type of outlet that needs to be used in wet, or potentially wet areas
What is a GFCI outlet?
The process that is used to disconnect and isolate a system from a source of energy in order to prevent the release of that energy
What is de-energization?
When the electricity arcs (jumps, or "arcs") from an exposed energized conductor or circuit part (e.g., overhead power lines) through a gas (such as air) to a person who is grounded (that would provide an alternative route to the ground for the electrical current).
What is electrical shock?
Common, natural event that can cause arc flashes to occur
What is a thunderstorm?
The color code system for signifying tests have been done on the electrical cords.
What is WHITE for 1st quarter, GREEN for 2nd quarter, RED for 3rd quarter, and ORANGE for 4th quarter.
***This color tape should be put near the end of each cord to signal the inspection has been completed.
How much clearance a forklift needs when working near powerlines
What is 10 feet?
Mechanical, electrical, hydraulic, pneumatic, chemical, thermal, stored, or other
What are energy sources?
This can include a potential pressure wave released from an arc flash. This wave can cause physical injuries, collapse your lungs, or create noise that can damage hearing.
What is an arc blast?
The best tool for electrical safety
What is proper training?
The most frequently failed inspections.
Electrical rough in.
The wires to the outlets.
What are branch circuit conductors.
The primary requirement for all disconnecting means.
What is they must be lockable in the open position.
This is the "can't let go" threshold of current flow for human exposure.
What is 9 to 25 mA.
The units used to measure resistance.
Ohms.
The maximum distance a GFCI can be located from the outside edge of a bathroom basin.
3 Feet.
Approximately 1/25th of a second.
What is how fast a standard job site GFCI trip and cut power.
Verification of isolation (trying to start the equipment or using a meter to verify zero energy state).
What is the critical final step of LOTO.
The term for dangerous explosive release of energy caused by an electrical fault.
What is an Arc Flash (or Arc Blast).
The chapter in the NEC that contains the regulations specifically for Emergency Systems.
Chapter 5
This must be inspected once a month and annually.
What is a fire extinguisher.
This type of jewelry is strictly prohibited when working on or near exposed energized parts.
What is Conductive metal jewelry or accessories.
This employee is the trained worker who locks out the machinery to perform service.
What is an Authorized employee.
It is acceptable to use double-insulated power tools in standing water or heavy rain because their housing protects against internal shorts.
(True of False)
What is False.
Double-insulated tools protect against internal electrical faults.
This safety device is specifically required in wet or damp areas.
What is GFCI.
Temporary string lights do not need protective bulbs or cages if they are shatterproof LED lights.
(True or False)
What is false.
Daisy chaining power strips to gain more outlets is a common workplace fire hazard.
(True or False)
What is True.
To save time during group maintenance, it is acceptable for a supervisor to hold the master key to all locks on a lockout box.
(True or False)
What is False.
"One Worker, One Lock, One Key"

What is before first issue and every 6 months thereafter.
This is the class of fire extinguisher used if an office computer monitor begins to smoke and spark.
What is class C.
