Oh no! I'm grounded
Doing this to a tool or electrical system means intentionally creating a low-resistance path that connects to the earth.
What is grounding?
The purpose of our 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?
This is an automatically operated electrical switch, designed to protect the equipment, and the electrical circuit wiring from damage caused by overload or short circuit. Not designed to protect people.
What is a circuit breaker?
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?
Electric shock may cause death by the following 4 ways.
What are Electrocution, shock, burns, and falls.
The second most frequently cited OSHA hazard
What is LOTO?
Risk of electric shock is greater in areas that are wet or damp. Install these as they will sense an imbalance of current and interrupt the electrical circuit before a current sufficient to cause death or serious injury occurs.
What is a Ground Fault Circuit Interrupters?
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).
Thomas Edison's first two children had nicknames that honored his work as a telegrapher and his love of Morse Code. What were they?
Who are dot and dash?
Though useful for temporary convenience, these items should not be used as permanent wiring.
What are extension cords?
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 awareness of dangerous electrical situations such as contact with power lines, lack of ground-fault protection and equipment not used in a manner prescribed.
What is hazard recognition/identification? completed.
In the field, one should stay at least 10 feet (3 meters) away from these electric pathways.
What are overhead wires (or power lines)?
Mechanical, electrical, hydraulic, pneumatic, chemical, thermal, stored, or other
What are energy sources?
This amount of current across the human heart can be fatal in as little as 2 seconds?
What is .1 amp
The best tool for electrical safety
What is proper training?
