Like in every work involving electricity, electrical safety comes first in the protection of both you the installer and any other person around you.
In this very important course, we shall look at electrical safety and we will let the experts and professionals in the electrical electronics industry guide and instruct us on measures and what to do.
Electrical safety is simply any measure we undertake to prevent anyone from getting exposed to the dangerous effects and harm of electricity.
We will look at electric safety basics. This time we will learn from University of Washington:
Don’t work with exposed conductors carrying 50 volts or more.
Make sure electrical equipment is properly connected, grounded and in good working order.
Extension cords may not be used as permanent wiring and should be removed after temporary use for an activity or event.
Surge suppressors with built-in circuit breakers may be used long-term and are available with three, six and 15 foot-long cords.
High amperage equipment such as space heaters, portable air conditioners and other equipment must be plugged directly into permanent wall receptacles.
Do not access, use or alter any building’s electrical service, including circuit breaker panels, unless you are specifically qualified and authorized to do so.
Wet environments can increase the risk of an electrical shock.
Also, we will look at the general protective equipment and tools. This is according to Princeton University.
Use of Protective Equipment
Employees working in areas where there are potential electrical hazards must be provided with and use electrical protective equipment appropriate for the parts of the body to be protected and the work performed. Protective equipment must be maintained in a safe, reliable condition and be periodically inspected or tested as required by 29 CFR 1910.137, Electrical Protective Devices. Where the insulating capability of protective equipment is subject to damage during use, the insulating material must be protected by covering with leather or other appropriate materials. Nonconductive head protection must be worn wherever there is danger of head injury from electrical shock or burns due to contact with exposed energized parts. Protective equipment for the eyes must be worn where there is danger of eye and/or face injury from electric arcs and flashes or flying objects resulting from electrical.
General Protective Equipment and Tools
Insulated tools and handling equipment must be used by employees working near exposed energized conductors or circuit parts if the tools and/or equipment may make contact with the conductors or parts. The insulating material of tools and equipment must be protected where it is subject to damage. Fuse handling equipment, insulated for the circuit voltage, must be used to remove or install fuses when the fuse terminals are energized. All ropes and hand lines used near exposed energized parts must be nonconductive. Protective shields, protective barriers, or insulating material must be used to protect employees from shock, burns, or other electrical related injuries while employees are working near exposed energized parts which might be contacted or where dangerous electric heating or arcing might occur. When normal enclosed live parts are exposed for maintenance or repair, the parts must be guarded to protect unqualified persons from contact with the live parts.
