driving electrical safety in your plant
DESCRIPTION
The proper use of personal protective equipment (PPE) is a critical component of any electrical safety program, and yet proper PPE use often is overlooked, diminished, or simply disregarded by electrical workers in manufacturing. Plant Engineering will present a Webcast on December 5th at 1 p.m. CT that will discuss the importance of PPE to mitigate arc flash dangers and other electrical safety issues.TRANSCRIPT

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?

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

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

Arc-Rated PPE – Clothing
Vertical Flame Test (ASTM D6413) not good enough alone.

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.

• 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

• 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

• 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.
