Preventive Electrical Maintenance from McPhee

electric safety 101
Electric Safety ‘101’
  • Three major hazardsof electricity, which are: 1) electrical shock, 2) electrical arc-flash and 3) electrical arc-blast.
  • A Qualified Personis defined as: “One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved.”
  • The safest wayto work on electrical equipment and circuits is to de-energize, lock, and tag them. Energized work is to be performed only as a last resort, when it is infeasible to de-energize.

Preventive Electrical Maintenance from McPhee

what is arc flash
What is Arc Flash?
  • OSHA/MSHA
    • Standards 29-CFR, Part 1910, sub part S (electrical) Standard number 1910.333
  • NFPA 70E
      • Standard for Electrical Safety in the Workplace 2012
  • IEEE 1564
    • Guide for Performing Arc Flash Hazard Calculations

An arc flash is a dangerous condition associated with the possible release of energy caused by an electric arc.

“Arc Flash” Generally Covers:

Electric Shock

Arc Flash

Arc Blast

Preventive Electrical Maintenance from McPhee

arc flash hazard analysis

What’s Required?

Arc Flash Hazard Analysis

An analysis investigating a worker’s potential exposure to arc flash energy.

Each analysis generally includes:

System data collection

One-line model & Analysis

Report & labeling

Each analysis generally covers:

Safe work practices

Shock & Arc flash boundaries

Proper PPE levels

Why does it matter?

The genie is (coming) out!

Injury Prevention

Safe work environment

Reduced insurance rates

It’s the law

Negligent Disregard

I don’t know what I don’t know

Why does it matter?

The associated human suffering is unconscionable

AND

mostly avoidable

  • Donnie’s Accident

slide9

Why does it matter?

OSHA

  • 13 incidents and $1.6M since the beginning of 2012
  • Violations can carry penalties of up to $250,000 for individuals or $500,000 for companies

Mine Safety and Health Administration (MSHA)

  • assessed $135,000 in fines against a contractor at the Cemex Balcones cement plant in Comal County, Texas.
  • "The contractor should have made certain the power was de-energized before testing the circuit."

How Does This Effect You?

  • Modification to current operating practices?
    • Do you allow employees and contractors to work on live electrical equipment? Procedure?
    • Lock out/Tag out procedures
  • Change to training requirements?
    • Identify who is a ‘qualified person’ and who is an ‘unqualified person’
  • Change to site contractor requirements?
    • Are your contractors trained AND following procedure?
  • Proactive or reactive?
    • Are you getting out ahead or will you be pulled kicking and screaming?

As a facility owner, you are responsible for safety of ALL workers on site and cannot pass off the liability by hiring contractors.

If you own facilities such as:

Quarries

Concrete Plants

Asphalt Plants

Sand Plants

Garages

Offices

The rest of the construction industry?

  • Electrical Workers
    • Can the work be done de-energized?
    • Threshold is ‘creating a greater (safety) hazard’ – not inconvenience or cost
    • Decision making in the absence of an incident energy calculation
  • Non-electrical workers
    • If they are not trained, they should certainly not be inside energized electrical gear
    • If energized electrical work is being performed, they should be out of the ‘approach boundaries’

As a subcontractor, owners are beginning to require specific details related to PPE and Arc Flash.

conclusions
Conclusions

The Key Question: Can it be done de-energized?

It’s important . . . . . personnel, $, liability

It’s coming . . . . . proactively or reactively

Beware . . . . . know what your buying

You’re responsible . . . . . for everyone on site

We can help . . . . . protect what matters!
