Death Due to Lack of Ground-Fault Protection


A journeyman HVAC worker was installing metal duct work using a double-insulated drill connected to a drop light cord. Power was supplied through two extension cords from a nearby residence. The individual's perspiration-soaked clothing/body contacted bare exposed conductors on one of the cords, causing an electrocution. No GFCI's were used. Additionally, the ground prongs were missing from the two cords.

Safety Does not Just Happen

Planning for a job properly prevents mistakes and injuries from occurring. Safety on the job is not
something that just happens; it should be an integral part of the planning process. Job briefings are a
great way to include and encourage all crew members in the safety planning process. Job briefings can be
held at the start of work shifts, as work tasks or hazards change, and as additional personnel arrive.

The hazards
The voltage levels involved
Skills required
Any “foreign” (secondary source) voltage source
Any unusual work conditions
The shock protection boundaries
The available incident energy
Potential for arc flash (Conduct a flash-hazard analysis)
Flash protection boundary
Number of people needed to do the job
Can the equipment be deenergized?
Is a “standby person” required?
Are backfeeds of the circuit to be worked on possible?
Job plans
Single-line diagrams and vendor prints
Status board
Information on plant and vendor resources is up to date
Safety procedures
Vendor information
Individuals are familiar with the facility
What the job is
Who else needs to know—Communicate!
Who is in charge
About the unexpected event...What if?
Test for voltage—First
Use the right tools and equipment, including PPE
Install and remove grounds
Install barriers and barricades
What else...?
Prepare for an emergency
Is the standby person CPR trained?
Is the required emergency equipment available? Where is it?
Where is the nearest telephone?
Where is the fire alarm?
Is confined space rescue available?
What is the exact work location?
How is the equipment shut off in an emergency?
Are the emergency telephone numbers known?
Where is the fire extinguisher?
Are radio communications available?

PPE Saves Lives

In the event of a momentary electric arc, flash fire, or exposure to energized equipment, a worker can find himself completely unprotected against forces that cause severe or fatal injuries. Everyday work clothes can ignite and will continue to burn even after the source of ignition has been removed. Normal clothes will continue to burn until the fabric is totally consumed, or will melt and cause severe contact burns to the skin.
Personal protective equipment (PPE) is your last line of defense and will be the major factor in differentiating between an electrical event you walk away from and one that requires months of painful healing. PPE comes in many different forms, including hard hats, gloves, goggles, safety shoes, flame-resistant shirts and pants, safety glasses, face shields, fall protection equipment, and more.

Too Many Workers Put Themselves at Risk
Each day, nearly 3 million professionals participate in
work activities where lockout/tagout procedures should be
used. Unfortunately, too many workers still put themselves
unnecessarily at risk by working energized or neglecting to
follow their company’s lockout/tagout procedures. Failure to
comply with the lockout/tagout standard is listed as one of
the top OSHA violations year after year.
Deenergize — Be Proactive About Your Safety
The number one way to prevent electrical injuries and fatalities
is to deenergize the equipment being worked on. It may take
a little more time and planning, but your life and your health
are worth it. Be proactive about deenergizing equipment and
taking steps to ensure that your work environment remains
Lockout/Tagout Helps Prevent the Unexpected
Lockout/tagout procedures safeguard workers from the
unexpected energization, or startup, of machinery and
equipment. They also can prevent the release of hazardous
energy during service or maintenance activities.
Lockout/Tagout Could Save Your Life
Always deenergizing and following established lockout/
tagout procedures saves lives. Compliance with OSHA’s
lockout/tagout procedures prevents an estimated 120
fatalities and 50,000 injuries each year. Workers injured on
the job from exposure to hazardous energy lose an average of
24 days of work to recuperation.
