With electricity, we are dealing with
something that cannot be seen but can be very destructive if the proper precautions are not taken. The
danger is always there so it is important to know the basics of protection in
order to eliminate the hazards. The rules listed here apply to electrical
installations used on a construction site--both temporary and permanent--but
can easily be applied to home use as well.
- Extension cords used with portable electrical
tools and appliances shall be of three-wire types. Grounds are never to be
removed from the extension cords.
- Temporary lights shall be equipped with
guards to prevent accidental contact with the bulb. Guards are not required
when the reflector is constructed in such a way that the bulb is deeply
- Temporary lights shall not be suspended by
their electric cords unless cords and lights are designed for this means of
- Splices shall have insulation equal to that
of the cable. NO TAPE!
- Electrical and extension cords or cables are
not to be laid on floors, in walkways, etc., unless it is impractical to do
otherwise. They should be suspended or secured in such a way as not to block or
hang in walkways, doorways or work areas.
- Panel boxes shall have a cover on them at all
times, except when being serviced and when a temporary cover is in place it
should be marked "HOT" to denote live current.
A GFCI MUST BE USED AT ALL TIMES.
- Before using make a safety check for loose
cable connections, bare wires, cracked outlets and missing or damaged face
- During use, be sure plug fits firmly and
check for any signs of heating caused by faulty connections.
- When finished, grab the plug to remove. Yanking
a cord from an outlet can:
- Break cord insulation and wires
- Pull loose wire connections
- Bend plug prongs
clips inside outlets
THE THIRD PRONG IS THE GROUND.
WITHOUT IT, ELECTRICITY ONLY HAS
ONE PLACE TO GO – THROUGH YOU!

Over the next few weeks, we will be focusing on electrical
safety and what to look for when inspecting tools, cords, and other sources
that carry electrical current. We start our series by focusing on the basics: electrical
Voltage - electrical pressure
Resistance - restriction to
electrical flow (pipe friction)
Amperes - electrical flow rate
Watts – amount of electricity
There are four main hazards
associated with electricity:
Shock: A shock can be defined as an electrical current travels in
closed circuits; occurs when a part of
your body becomes part of an electric circuit; or when an electric current enters the
body at one point and exits the body at another
Arcing or Sparking: Arcing or sparking occurs when
high-amperage currents jump from one conductor to another
Explosions: Occur when electricity
provides a source of ignition for an explosive mixture in the atmosphere
Fires: Electricity is one of the most
common causes of fire

February 14, was not only Valentine’s Day, it also marked our 75th anniversary.
Happy Anniversary to everyone at Donley’s and to all of our clients and team partners! Thank you for being such important part of our history and future.
Ernest F. Donley’s Sons was founded on February 14, 1941. The Founders started the business in February, 1941 by purchasing the Construction Department of Donley Brothers . Donley's started as a formwork contractor and jobbers of contractor 's hand tool s. At the time, there was a small lathing for plaster business, mainly residential and light commercial. The formwork business was mainly pans and open centering, plus beams and columns. For pan or one-way, joist jobs, Donley's was very competitive and was the only local source for metal pan forms. World War II started just after Donley's was incorporated and very quickly the emphasis changed from construction to industrial mill supplies, including saw sales and sharpening. The basic tool lines being distributed to contractors also had industrial application. The saw sharpening and hand tool business expanded and various lines were added that broaden the scope to include automotive tool jobber lines.
Today marks the beginning of our anniversary celebrations. You will notice that our new anniversary logo has been integrated into our website, email signature and letterhead. We will also creating job site banners that will be put in place in March. There will be many different ways that we celebrate this year, so stay tuned.
Due to the building boom of the 60’s and 70’s in downtown areas, many office buildings and parking structures are nearing or have passed 50 years of use. As these facilities age, concrete is one area in particular that can be susceptible to structure and aesthetic damage due to wear and tear of operations. Since the 1990’s Donley’s Restoration Group has been focused on assisting building owners assess these issues and develop and implement plans restore these facilities.
Structural concrete repair is a dynamic process by which deteriorated elements of a structure--such as a parking deck-- are removed and new materials are integrated into the existing structure to form a restored structure capable of withstanding the elements. The final result is a beautiful and smooth surface which will last for years, without the expenses associated with a complete tear-down and rebuild.
Donley’s Restoration Group (DRG) specializes in the latest state-of-the-art structural repair solutions that will maintain the structural viability of your concrete structures. What sets DRG apart from our competition is our quality, workmanship, and technology. Concrete is at the core Donley’s business and has been since its founding in 1941. The organization has perfected its operation over the past 75 years. We know what products work best in different environments, how to apply them, and what it takes to maintain them. We are a licensed applicator for all of our protective and preventative maintenance products. This expertise ensures that not only will the correct products be used in their intended application, but they will also be installed correctly.

We previously posted an article regarding power tool inspections and safe use. Because power tools are important in any job and if not used properly can result in serious injury, we thought it worth sharing again.Pre Use Inspection
Ensure work area is free of any potential trip hazards and is clean. If a power tool has any of the following issues, it should not
be used for any job:
- Damaged or cracked housing, power source, or bits/accessories
- Dull blades (often more dangerous than sharp blades)
- Missing guards or protective devices
- Leaking gasoline, oil or other fluids
- Appears to be in poor condition
- Tool does not have 3-wire cord or is not double insulated
In construction, portable power tools with defective wiring cause many injuries. The following practices will help everyone stay safe:
- Wear correct PPE
- Always wear eye protection
- Use proper tool for the job
- Use tools with 3-wire plug and make sure connections are tight
- Disconnect tool before making adjustments
- Follow the manufacturer’s instructions
- Ask supervisor or coworker about use, if unsure
- Do not point or operate tools in close proximity to other individuals
- Use spark resistant tools when working near a fuel source
- Do not use excessive force to cut/drill through hard materials
- Never place hand behind the material that is being worked on when the tool could push through
- Gasoline/ mixed fuel powered tools must be off and cool when re-fueled; use only in well ventilated areas
