Yes
From 2008 to 2018 what was the estimated rate of increase of the need for qualified electricians in percentage
12%
List two main electrician categories
Construction electrician 309A, industrial electrician 442A
List three attributes to a construction electricians role
Basic knowledge of electrical theory, extensive knowledge of Canadian electrical code and wiring practice
What are industrial electricians general concern like what is typically the role?
Maintaining equipment that has already been installed
List three aspects of an industrial electricians role in industries
Installation of motors, basic knowledge of electrical devices and motor controls
Are instrumentation technicians considered electricians
Yes
List at least five industries that are related to the electrical industry
Arc conditioning and refrigerator, aircraft electronic, automotive, cable TV and broadcast media
There are union and non-union electricians which of these two represent the larger percentage of electricians
Non union electricians
In a paragraph or point form discussed ethics and how it relates to being a successful electrician
Having a good reputation for doing quality work and dealing honest with customers
In a paragraph or point form discussed the role that an electricians appearance make in the electrical industry
A professional person is expected to look professional no filthy clothes
List the three main components of communication
Speaking, listening and writing
In paragraph or point form, discuss the importance of each of these main components of communication
When speaking, no slang and communicate with people in your field, when riding, you must have clean writing when listening, understand what someone is saying
When looking at figure occupations with regards to working as a part of a team, discuss in either point form or paragraph with the point this image is trying to make
Communicate to people around you be respectful of other people‘s trades and help other people
Do electricians need to understand the role that building code plays in the electrical industry
Yes
What is the first role with regards to an electrician performing tasks?
never work energized
List the three step check to verify that the power is turned off
Test the metre on known live circuit turn off power and test the circuit that with metre and test the metre on the known live circuit again to make sure the metre is working
When you are using a multimeter, is this considered to be working energized
Yes
If using a multimeter is considered to be energized work then how can an electrician safely use a multimeter in the electrical industry ?
By taking precautions and using the lockout tag out to be sure, no one energize the circuit
Is it illegal for electricians in Ontario to use a multimeter at work to do live testing if they have not had training and or if the company they work for does not have procedures and or if there is a safer method other than live testing to determine functionality
Yes
Why is it important to think before before you touch something that could cost you your life?
Cause many technicians have been killed by dead circuits when they’re not really dead so double check to be sure
Why is it important to avoid horse play when at work?
Because horse play can get people hurt or killed
When is it especially important to never work alone?
To have someone with you to turn the power off or give artificial respiration (CPR)
Why should you work with one hand around electrical equipment when possible?
To prevent the path of electricity to go to one hand to another in going through your heart killing you
Why should anyone who is working on electricity learn first aid
A knowledge of CPR could save someone’s life
Why is it important to avoid drugs and I’ll call on a works site
Alcohol and drugs abuse have killed thousands of people
We all know that electricity has the potential to kill a person, but what aspect of electricity actually causes a death is it the voltage or the current?
Current
Does every person have the same effect on their body if they get electrocuted please explain in paragraph or point form
No cause everyone has different amount of resistance in their body all depending on what they ate to how much they sweat
What is the current range expressed in amps that crosses the heart that can cause death?
200 mA or 0.2 A
Why is 120 V AC considered to be the most dangerous voltage to work with?
Because that causes a current flow between 100 to 200 mA, which can cause death and it’s the most common circuit
Standard 100 W lightbulb in most home use about one amp of current how many milliamps does that single lightbulb pack use?
1000 mA
If it takes 200 mA to kill a person, what percentage of current does the single hundred watt lightbulb possess?
thousand milliamps
Large amount of current can cause severe electrical burns. Why are they often very serious?
Because they occur on the inside of the body
What is CCOHS and OH&S and what is their purpose?
To advocate for the complete physical, psychological and mental well-being
What is CSA-Z462
The requirement for workplace electrical safety in Canada. It is necessary for the protection of electrical worker, only acceptable standard safety in Canada.
What is your employers responsibility?
Identify potential workplace hazards, and carrying out preventive measures that prevent accidents or injuries caused by the hazards
What is a lockout and tag out LOTO
Procedure are generally employed to prevent someone from energizing a piece of equipment by mistake
Is it important to follow your companies prescribed LOTO procedures?
Yes, some companies have their own policies
Other than feet protection, safety boots list, the six heading of protective clothing listed in the textbook in which electrician should be aware of and will need to wear at all times in the electrical industry
Head protection, eye protection, hearing protection, fire, retardant, clothing, gloves, and safety harnesses
What is a ground fault
It is a circuit interrupter to prevent people from being electrocuted
What does GFCI stand for and what is it
Purpose
Ground fault, circuit interrupters
At what milliamps is a GFCI designed a trip
5 mA
What does AFCI stand for and what is it intended to protect against?
Ark fault circuit interrupters it is intended to protect against fires
What is the purpose of grounding and bonding?
To provide a low resistant path for ground to prevent conductive objects from existing at a high potential
Is it considered to be extremely dangerous to install a system that has incorrect bonding and grounding?
Yes
Is it illegal an extremely dangerous to use a plug that has had the bonding prong removed?
Yes
