What if an Arc Flash Hazard Exists?

An Arc Flash Assessment determines if an Arc Flash Hazard exists. If an Arc Flash Hazard exists, the assessment determines 3 important items: Safety-related work practices to use. Arc Flash Boundary PPE to use within the Arc Flash Boundary To learn more about an Arc Flash Assessment and for a review your company’s electrical equipment needs, contact Reuter Hanney today at bids@reuterhanney.com.

If an Arc Flash Hazard exists during an Arc Flash Assessment, three (3) important items are determined:
  1. Safety-related work practices to use
  2. Arc Flash Boundary
  3. PPE to use within the Arc Flash Boundary

An arc flash is the result of a rapid release of energy due to an arcing fault between phase bus bar and another phase bus bar, neutral or a ground. An arc flash can generate over 5,000o F in under a second.

Shock Protection Boundaries – How are they determined?

Shock Protection Boundaries - NFPA-70E

Shock Protection Boundaries, According to NFPA 70E-2015, is determined by a Shock Risk Assessment. The Shock Protection Boundaries as follows:

  • Limited Approach Boundary. Unqualified persons may not cross a limited approach boundary, except if escorted by a qualified person and they are advised of possible hazards.
  • Restricted Approach Boundary. Only qualified persons may cross a restricted approach boundary and only with appropriate PPE.

Reminder: Shock Protection Boundaries no longer include a Prohibited Approach Boundary.

NFPA 70E: Standard for Electrical Safety in the Workplace®. Originally developed at OSHA’s request, NFPA 70E responds to the latest information about the effects of arc flash, arc blast, and direct current (dc) hazards, and recent developments in electrical design and Personal Protective Equipment (PPE).

Preventive maintenance including inspection, testing, and servicing of electrical equipment should be done on a regular basis. Contact Reuter Hanney, The Electrical Power Specialists, today at bids@reuterhanney.com for a review of your company’s electrical equipment needs and to learn more about safety, and safety maintenance procedures.

When is an energized work permit NOT required?

Energized Work Permit Not Required - NFPA-70EEnergized work permit not required, according to NFPA 70E-2015, if a qualified person is provided with and uses PPE and safe work practices under the following conditions:

  1. When testing, troubleshooting, and voltage measuring.
  2. When thermography and visual inspections are conducted as long as the restricted approach boundary (RAB) is not crossed.
  3. When entering and leaving an area with energized electrical equipment if no electrical work is performed and the RAB is not crossed.
  4. When performing general housekeeping and other non-electrical tasks, if the RAB is not crossed.

When is energized work required?

Energized Work Required - NFPA-70EEnergized Work Required Compliance

Energized work must meet NFPA 70E: Standard for Electrical Safety in the Workplace® requirements to be performed safely. Energized work is required when a person must show demonstrated skills and knowledge related to the construction and operation of electrical equipment and installations and has received safety training to identify and avoid the hazards involved.

When is energized work permitted?

Energized Work Permitted- NFPA-70E

Energized Work Permitted Compliance

Energized work must meet NFPA 70E: Standard for Electrical Safety in the Workplace® requirements to be performed safely. Energized work is permitted when:

  • It can be demonstrated that de-energizing introduces additional hazards or increased risk.
  • It can be demonstrated that the task to be performed is infeasible in a de-energized state due to equipment design or operational limitations.
  • Electrical conductors and circuit parts operate at less than 50 volts.

Circuit Breaker Panel Covers Provide Protection

Circuit Breaker Panel CoversCircuit Breaker Panel Covers Provide Protection when they are properly installed and maintained.

How many times have you seen circuit breaker panel covers with loose or missing screws? The covers are intended to prevent accidental contact with energized parts inside the enclosure. Loose or missing screws may allow access to those energized parts by unqualified persons.

Many panels are in locations accessible only to qualified personnel, but many are not. For example, many schools, hospitals, and office buildings have panels located in hallways accessible to unqualified people. Objects have been known to be poked through openings such as these.

Securing the circuit breaker panel covers also helps in the event of a failure within the inside of the panel. While the cover may not completely contain an arc flash event inside a panel, it would limit the flash escaping. Completely securing the cover would make it less likely to become a missile due to an arc blast.

Preventive maintenance including inspection, testing, and servicing of electrical equipment should be done on a regular basis. Contact Reuter Hanney, The Electrical Power Specialists, today at bids@reuterhanney.com for a review of your company’s electrical equipment needs and to learn more about safety, and safety maintenance procedures.

 

Oil Filled Electrical Power Equipment Tests

Oil Filled Electrical Power Equipment TestsRecommended Tests for your oil filled electrical power equipment:

1. Liquid dielectric screen test

2. Karl Fischer moisture analysis test

3. Dissolved Gas Analysis test

Stress on the electrical power equipment needs to be monitored to ensure reliability. Regular sampling and testing of insulation oil taken from the transformer is a valuable technique to understand the condition of the oil. The testing can identify measures needed for preventative maintenance action including extending the life of the transformer.

Run Dielectric Fluid Test Annually

Ideal Time to Run Dielectric Fluid TestRun Dielectric Fluid Test Annually. It is ideal to run a Dielectric Fluid Test at least once a year. In certain circumstances such as if test results indicate a significant change such as a large increase in key gasses or moisture content then a Dielectric Fluid Test should be run every three to six months.

Test the insulating fluid in the power transformer before a failure occurs. As a transformer ages, the dielectric fluid can contain gas and contaminants that have dissolved in it over time causing a transformer failure. Dielectric fluids in a transformer can be analyzed to find out the condition of the dielectric fluid. The testing can identify measures needed for preventative maintenance action. Transformer oil analysis is a cost-effective preventive maintenance tool for your electrical power system.

Preventive maintenance including inspection, testing, and servicing of electrical equipment should be done on a regular basis. Contact Reuter Hanney, The Electrical Power Specialists, today at bids@reuterhanney.com for a review of your company’s electrical equipment needs and to learn more about safety, and safety maintenance procedures.

Prevent Transformer Failures with Dieletric Liquid Testing

Prevent Transformer FailuresPrevent transformer failures with dielectric liquid testing on transformers. As a transformer ages, the dielectric fluid can contain gas and contaminants that have dissolved in it over time causing a transformer failure. Three reasons to test transformers with dielectric testing:

1. Early indicator of a problem you may have

2. Relatively easy to do

3. Inexpensive test that provides a lot of diagnostic information.
