Top 10 Mistakes
ElectricalWorkplace Safety
1. The 100 cal/cm² Delusion: The “err-on-the-side-of-safety-mistake”
ElectricalWorkplace SafetyHow Bad is Bad?
Electrical Hazards – Arc Flash
Watch the disconnect door.
How much protection would work in this arc?
Is over protection a good idea?
What works best here, PPE or work practices or a combination?

Arc-in-a-Box
Electrical Hazards – Arc Flash
Watch the disconnect door.
Arc-in-a-box energy can be two to twelve times greater when the arc is an arc in a box situation.

“Tracking” Arc
Electrical Hazards – Arc Flash
“Tracking” arcs are “arcs” which conduct through skin and “pop out” between skin and clothing.
• Can cause ignition of clothing in an electrical contact
• Usually occurs at higher voltages

Avoiding Mistakes
• Overkill on PPE “sounds” smart but it has two negatives
– Sends the wrong message
– If the workers don’t believe you they may cut corners when no one is watching.
– Watch out for salesmen’s little lies…
– Better safe than sorry??
– Better safe and right
Match PPE to the hazard

2. “We got ‘dem kits” programs OR“We have coveralls” programs
ElectricalWorkplace Safety
Avoiding Mistakes
• Making the program cheaper or easier for management or the safety department or for enforcement may not be the most cost effective or the best program.
• A natural program that becomes a worker’s habit is the most reliable.
• Tends to over protect or not protect at all.
• Match the kit to the level
– Don’t buy 100 cal kits for everyone.
• Arc rated daily wear is better than a “coverall program.”
– Darlene’s story
Make the program easy for the worker

3. The “get-a-Size-12-Class-2-rubber-glove-for-all-arc –exposures”
Program

She needs smaller gloves
He needs special coveralls/suits

4. The “Flame Resistant(FR)-labeled-clothing-is-all-I-need-in-the-electric-
arc” delusion.
ElectricalWorkplace SafetyArc Rated or “FR”?
Arc-Rated PPE – Clothing
Vertical Flame Test (ASTM D6413) not good enough alone.
ElectricalWorkplace Safety
Arc-Rated PPE – Clothing
Beware of:
• “FR until washed or dry cleaned”
• Melting “FR”
• “FR-treated” acrylics, polyester, nylon
Got Arc-Rating?
Because of the misuse of the term FR, NFPA 70E removed the term favoring arc-rated.
ElectricalWorkplace Safety“FR” Melted Onto the Head
Arc-Rated PPE – Clothing
ElectricalWorkplace SafetyRainwear
Arc-Rated PPE – Clothing
Not all FR rainwear is arc rated. Any FR rainwear with a melting substrate will usually increase
worker injury.

5. “We bought this PowerPoint” Programs
ElectricalWorkplace Safety
• Generic training doesn’t always get to the finer points.
• Site specific written programs are critical
• Unique hazards must be considered
– FR cotton and 20% body burns from sodium hypochlorite.
– Aramids and welding spatter.
– Melting polyester in cleanrooms.
• Train + Audit + Knowledgeable Management = A Great Program
Top 10 Mistakes
ElectricalWorkplace Safety
6. The “buy-everyone-an-arc-flash-suit-and-do-calculations-later”
delusion
ElectricalWorkplace Safety
• Assessment will not change the level of protection but it will change how often you need to wear it.
• Don’t put off PPE purchases waiting on assessment
• Daily wear for all electrical workers
• Suits for high level exposures
• Operators work in natural fiber or are rated gear depending on level of exposure.
Don’t put off PPE purchase but

7. Focusing on Arc Flash rather than Shock
ElectricalWorkplace Safety
• Shock is the number one killer of the electrical hazards.
• More bang for the buck with right PPE than engineering. Most important engineering is done by proper installations, maintenance then equipment upgrades. Engineering out the arc flash hazard is not always an option.
Top 10 Mistakes

8. Ignore specialty Gear
ElectricalWorkplace Safety
Avoiding Mistakes
• ASTM F1506
– Hairnets/beardnets
– Cleanroom gear
– Gloves (Proposed separate Standard)
– Disposable FR Wear
• ASTM F1891
– Rainwear
– Chemical gear + Chemical Standard
• ASTM D2413 + D1116
– Shoes (EH or DI or leather, etc.)
• Other Specialty PPE must be evaluated by the AHJ
Don’t forget specialty gear

9. Safety Department Can Do it On Our Own, Safety Myopia:
“The Daisy Chain Delusion”

Avoiding Mistakes
• The five people you need to do proper hazard assessment for electrical
– Trouble making electrician
– Nicest electrician
– Smartest electrician
– Electrical Engineer
– Safety Person

Three Types of Audits Required
Observations required to do the following:
• Identifies:• Demonstrate task
proficiency • Retraining needs• Supervisory level• Part of evaluating
Qualified Persons
Supervisory Safe Work Practice Inspection
NFPA 70E 110.2(D)(1)(f)
Minimum annual supervisory work practice inspection to monitor safe work practices

Three Types of Audits Required
Better practice: Separate from Supervisory Audit.Observations required to do the following:• Prove procedures work• Identify:
• Procedures that don’t work• Changes that should be
made• Retraining needs
Annual Field Work Audit
Site audit looks at the site’s practices and could include NEC auditing and NFPA/OSHA auditing 110.4 (H)(2)
Best practice: Separate from Supervisory Audit.• Year One: Internal by
local safety/electrical dept.
• Year Two: Cross-pollinate using another professional from another plant or industry
• Year Three: Outside Audit by competent auditor

Avoiding Mistakes
• Documented electrical safety program audit (not more than every 3 yrs.)
NFPA 70 E 110.3 (H)(1)
• Must reviewed Arc Hazard Assessment minimum of every five years.
– Updates required if major modifications or renovations.
– Required for calculations or if Tables used.
– Should include audit of labeling.

Safety-Related Work Practices
Habit 1 Always verify absence of voltage & use VR gloves & tools.
Habit 2 Establish worker safety boundaries from shock & arc flash.
Habit 3 Always wear arc-rated daily wear and a face shield.
Habit 4 Always use GFCI with cord connected tools & extension cords.
Habit 5 When feasible create an electrically safe work condition.
Habit 6 Plan your jobs, use standards to identify greater hazards, & adopt controls & PPE to mitigate hazards.
Habit 7 Measure, audit & continuously improve electrical safety processes.
