This electrical awareness video is focused on identifying hazards
around electricity on the job-site.
All other hazards on the job require the same focus and respect while
performing your hazard assessments.
And should not be disregarded or have any less importance placed on them.
Electricity is all around us.
It is an essential element in our daily lives.
Nearly everything we do is connected with electricity.
On the job-site, working around electricity
can be very safe when workers properly identify and mitigate the hazards.
If hazards are ignored, electricity can strike out,
and its effects can be devastating.
As with any task on the job-site, you should never
attempt to perform work without the proper training and experience.
Only qualified personnel should be involved in the operation
or repairs of electrical equipment.
Inadequate training, lack of experience, and failure
to recognize potential hazards could result in electric shock or arc flash.
Electric shock can occur when a worker approaches or contacts
exposed energized electrical equipment.
Workers' exposure to electric shock can vary
from a tingling sensation to involuntary muscle contraction causing
respiratory paralysis, ventricular fibrillation,
and severe internal and external burns, and even death.
The victim is also at risk of other serious physical harm
such as falling from heights.
Arc flash results from two electrical components sustaining an arcing fault.
If conditions are correct an arc flash will result, followed by a blast wave
containing molten metal, shrapnel, and toxic gases.
No matter the severity, any worker exposed
to any level of electrical shock or flash must seek medical attention.
While electricity has the power to seriously harm you,
the risks of electrical shock can be mitigated.
And work can be safely carried out without incident.
Electrical safety begins with the proper use of field level hazard assessments,
and identifying the potential hazards.
Your hazard assessment is the first step in protecting you
and everyone else on your job-site from any associated hazards, which
may include electric shock.
A brief inspection of your job-site will help identify
other potential electrical hazards.
While performing your walk-through, look, listen, and smell.
This will assist you in identifying the hazards on your site.
All power tools and equipment should be plugged into a GFCI, this is a must
when working in wet, moist, or exterior locations.
Ground-fault circuit interrupters monitor
the balance of electricity flow.
And can detect even minor imbalances, and will trip,
reducing the risk of electric shock.
Bump testing the GFCI before for must be done to ensure the unit
is functioning properly.
By pressing the Test button, the receptacle should trip.
Pushing the Reset button should restore power to the GFCI.
If this fails, the GFCI unit is defective,
and must be taken out of service.
Adequate lighting is a must in your work area.
If light levels are too low, additional lighting
must be installed on either a temporary or permanent basis.
Whenever working directly around electrical equipment,
the deenergizing of equipment is the recommended practice.
Deenergizing equipment removes the potential for electrical shock
as power is removed.
This can be achieved with the proper use of a lockout/tagout system.
While basic procedures may vary from site-to-site, it is essential for you
to understand the lockout/tagout procedure being used at your job-site.
One thing that does not change from site-to-site,
however, is that you may never remove another party's
lock in a lockout/tagout system.
Before using any electrical cords or tools,
always inspect individual items to ensure they are in good working order.
Faulty equipment can lead to personal injury, and poses a risk to all those
on a job-site.
If items are damaged or are in poor working condition, tag the item,
and take it out of service for repair or replacement.
Always know the locations of fire extinguishers on your site.
These should be rated safe for use with electrical fires.
Common practice is the use of a dry chemical type ABC fire extinguisher.
Depending on the type of work you're doing, a hot work or electrical permit
may be required.
Always ensure you're in compliance with your site-specific policies
and procedures regarding permitting controls.
Always consider overhead hazards in your work area.
Power lines are an ever-present danger due to the possibility
of electrical or direct contact, and should always be marked.
High voltage hazards can also be in the ground.
Line locates are required by law before any ground disturbance takes place.
Always call before you dig.
Occupational Health and Safety regulates minimum work distances
to electrical sources with certain voltages,
and should be referred to before working near any high voltage sources.
It is extremely important to recognize equipment
in an abnormal condition such as an open electrical panel, exposed
wiring, sparks, smoke, or fire.
When you encounter this situation, use the look, listen, and smell approach,
as this is an immediate cue that extra caution should be used.
And may indicate a potentially dangerous situation is present.
Water or liquids pose additional risk of electrical shock
due to high conductivity.
The hazard should be removed, only after the area is deenergized.
If you recognize a hazard that you cannot rectify,
ensure that you ask questions and seek solutions from the appropriate
personnel on-site.
Do not take it for granted that other workers understand
the scope of your work or that there is a potential danger to you or to them.
Common PPE requirements on job-sites include cotton or fire-resistant pants.
A cotton or fire-resistant shirt with a minimum 6 inch to full length sleeve.
Electric shock-resistant or static-dissipative footwear.
Type one and two class E and G protective headwear.
Additional high vis clothing, safety glasses, and work gloves.
For electrical workers that conduct their tasks around energized equipment,
you should be aware of the CSA standards Z462.
Competent workers need to be trained to this standard, which
will help identify the hazards associated around electrical sources.
What controls can be best used, as well as the additional specialized PPE
required, such as arc flash clothing, arc
flash face shield, rubber-insulated gloves which
include leather protectors, and more.
PPE is your last line of defense.
Do not use PPE as a substitute for the opportunity
to control or remove existing hazards.
In the event that all safeguard systems have failed
and a co-worker is being shocked, never come in direct contact with the worker
or you may become entrapped in the shock cycle.
If possible, deactivate the power source,
and activate your emergency response plan.
Working around electricity can be performed safely and without incident.
By executing sound judgment and diligent observations in order
to create your field level hazard assessment
And by following the proper safe work procedures, you'll be well on your way
to completing your task without incident.
Remember the importance of using the proper equipment in good condition.
And by wearing the proper personal protective equipment.
By employing all these safeguards, not only will you
help keep yourself and your co-workers safe,
you'll help ensure that you'll return safely every day to the people who
count on you the most.
