The IEEE / NFPA Arc Flash Collaborative Research Project is ready to begin testing that, ultimately, should lead to more accurate and effective arc flash standards. An article on the IEEE site provides background on the project.

The goal of the IEEE / NFPA joint research is to create rigorously-tested models of arc flash phenomena that can serve as a reference in creating improved formulas and safety codes. In addition to exploring the effects of varying voltages, arc gaps, enclosures, and so forth on incident energy, researchers will be investigating secondary hazards of arc flash such as toxic gases, sound waves, and ultraviolet radiation.

A network of laboratories around the world, carefully vetted by IEEE / NFPA project members over the last year, will be participating in the study. Total costs of the research are expected to be $6.5 million, of which more than half has already been raised. Ben Johnson, project co-chair, stated: "I expect that we’ll gain information that can lead to improved equipment...if we can save just one life, all this is worth doing.”

A recent article in the NFPA Journal discusses the thorny question of whether, and in what circumstances, personal protective equipment should be worn when there are no live, exposed electrical parts. Technically, when there are no exposed parts, there is no flash protection boundary—but there may still be a risk of injury. Equipment doors can be blown open and panels blown off by an arc flash explosion, and hot gases can escape through louvers or cracks and cause burns.

In a facility using the PPE tables provided in NFPA 70E, there are a few instances where PPE is required even though no live parts are exposed. For instance, Table 130.7(C)(9)(a) lists the required PPE for "Circuit breaker (CB) or fused switch operation with doors closed" as hazard/risk category 2. However, even for facilities which do not rely on the NFPA 70E tables, safety-consciousness will often suggest wearing more PPE than is explicitly required.

In the 2009 edition of NFPA 70E, a new fine-print note will be added, which will state in part,
The collective experience of the task group is that in most cases closed doors do not provide enough protection to eliminate the need for PPE for instances where the state of the equipment is known to readily change, i.e. doors open or closed, rack in or rack out.

While a fine-print note is not a formal requirement, arc flash safety isn't about following the letter of the law. True safety consciousness requires taking appropriate steps to minimize all hazards—and wearing PPE is often one of those steps.

Bill Giffen was hit by an arc flash incident last year while working as a Master Electrician. The resultant injuries have left him permanently disfigured, and have had a serious impact on his personal life. On his web site, www.arcflashsurvivor.com, Bill tells his story and provides photos of the accident's aftermath.

Bill sees his first-hand experience with the dangers of arc flash as giving him a mission to help inform other electrical workers of the importance of safety consciousness. He offers a presentation designed, in his own words, "to bring the very real face of an accident to you, your employees and your co-workers." More than a run-through of dry safety procedures, Bill's presentation is designed to provide a wake-up call to the importance of using well-planned, safe procedures every time--because it only takes one lapse of judgment to change a worker's life forever.

A portion of the proceeds from Bill's presentation is donated to trauma and burn centers.
An article in IMPO Magazine, written by Joseph Weigel of Square D Services, Schneider Electric, discusses the important role that electrical system maintenance plays in protecting against arc flash.

Fault clearing time is central to mitigating the danger posed by an arc flash. However, without proper maintenance, upstream overcurrent protective devices may not be able to respond adequately in the event of an arc fault. Weigel writes,

When these devices are not maintained on a regular basis, their clearing time may increase, allowing more energy to be released in an event. If maintenance is deferred long enough, it may result in a worst-case condition that may render the device completely inoperable, meaning it will not open to clear a fault of any magnitude.

An improperly maintained electrical system may look safe on paper, but pose significant dangers in reality. Malfunctioning protective devices can greatly increase the incident energy released by an arc flash; devices which don't function at all may as well not exist.

NFPA 70B, "Recommended Practice for Electrical System Maintenance," provides a useful guide to ensuring that protective devices maintain full functionality. Unfortunately, NFPA 70B compliance is far from universal, as it is a voluntary standard not required by OSHA.

An article by Larry Altmayer of Littelfuse, published at PlantServices.com, outlines the expertise and resources needed to perform an adequate electrical safety assessment and arc flash hazard analysis. The article addresses the important issue of whether to take on the cost of hiring an electrical safety consulting firm, or to face the considerable task of performing an analysis in-house.

Electrical engineering know-how is, of course, a key factor. Altmayer states, "Electrical hazard assessments are complex, and unless you understand the special expertise required you risk falling short of OSHA requirements." Engineering expertise, and familiarity with your facility's electrical systems, are necessary for a hazard assessment, but they're not enough. In-depth understanding of OSHA, NFPA 70E, and IEEE 1584 requirements and procedures is needed in order to ensure accuracy and compliance with the relevant codes.

Expertise isn't the only thing to consider in deciding whether to outsource or work in-house. A thorough hazard analysis is time-consuming and can be costly. Also, specialized equipment such as arc flash software and Category 4 PPE (for use while determining device characteristics) may be necessary to complete the assessment, while the ability to produce warning labels in large quantities is necessary for implementing the study's results. Liability for the safety of assessment workers is another concern. A final factor to consider is training: do you have the staff and resources to fully train workers on the hazards they will encounter in your facility?
An article in the May/June issue of the NFPA Journal discusses the changes in arc flash labeling requirements that are included in NFPA 70E - 2009. The opening paragraph states:

"Since arc flash labels were first required in 2002, there have been many differences throughout the industry between the wording and the choice of signal word and color. The 2009 edition of NFPA 70E, Electrical Safety in the Workplace, will require, for the first time, that one of two pieces of information be on the label: either the required level of personal protective equipment (PPE) to wear or the available incident energy. However, it leaves the color and signal word of the label and any other information the facility wants to put on the label up to the discretion of facility management."

This is currently the most read online article in the NFPA Journal. You can read the article here.

We are one of the largest suppliers of arc flash labeling equipment and supplies. We also offer the Vinyl Zapper, a device that quickly removes old labels without damaging te underlying surface. This allows old labels to be quickly and easily replaced.

Arc flash helmet and face shield from Extreme Safety

Protecting the face and head region from arc flash hazards is crucial. The face shield and helmet combination does the job effectively and barely restricts movement or causes an inconvenience.

The face shield is designed to deflect blast energy away from the face, while absorbing heat and spatter. The helmet is simply a mounting device for the face shield, but is made of similar material. Standard face shield and hardhats will melt in an arc flash; for that reason you should only use arc flash approved PPE.

A new add-on for the face shield is the Nomex flap. The flap attaches to the bottom of the face shield, and hangs down to the chest. This creates a mechanical barrier between to cover the gap between the face shield and chin area.

Although the face shield and helmet achieve their 10ka/1sec arc flash rating without this flap, it is an approved extra feature suitable for some applications.

More information is available from Extreme Safety.

Graphic Products has just released the new DuraLabel PRO 300 industrial label printer. This is a high resolution 300 dpi thermal transfer printer that incorporates high-speed processing to provide fast printing of labels and signs.

This new printer provides five options for printing arc flash labels and signs.

The DuraLabel PRO 300 comes with the Flash Label database software. This software is used to create, print and store arc flash labels. Labels are printed using preformated 4"x6" die-cut labels that are available with either a danger or a warning header. Die-cut labels are available in both English and Spanish.

The die-cut labels may also be printed using generic software such as Microsoft Word or Excel, or using arc flash calculation software such as EasyPower.

As a third option the DuraLabel PRO 300 can use continuous two-color vinyl. This is a white vinyl tape with a colored header section typically used for a signal word. Two-color arc flash labels can be formatted to include any desired information. Two-color vinyl is available in four inch widths and may be printed in nearly any desired length. Two-color continuous vinyl is unique product available only for the DuraLabel line of printers.

Single color continuous vinyl is an option that provides total flexibility in label design. Information can be formatted and arranged to suit facility requirements.

The DuraLabel PRO 300 can also print text and graphics spanning multiple strips of vinyl. This means arc flash signs can be printed by combining strips of single color vinyl. For example, two 36" strips of orange tape and four 36" strips of white tape would be combined to create a 24" x 36" arc flash warning sign.

In addition to arc flash labels the DuraLabel PRO 300 can print a wide range of other types of labels and signs. From wire markers to pipe markers, tamper evident labels to glow-in-the-dark signs... the DuraLabel PRO 300 gets the job done right.

Use the links above for more information about the DuraLabel PRO 300 printer.

An article in Plant Engineering Live, by Joseph Weigel, of Square D Services, Schneider Electric, provides some recommendations for selecting an arc flash analysis provider.

The article begins by providing an overview description of an arc flash analysis followed by a short discussion of standards. It then talks about the factors that should be considered when selecting a provider of your arc flash analysis.

The article concludes by saying:

"Purchasing an arc flash analysis for an industrial facility is very important for electrical safety standard compliance and also is required in order to provide the safest possible workplace for employees. However, like any product or service, when purchasing an arc flash analysis, one tends to get what one pays for, which is why qualifying providers should not be taken lightly. But more importantly, a facility owner or manager should also be careful not to be wooed by low bids.

Thus, a careful and thoughtful approach to an arc flash analysis purchase and qualifying providers, can help ensure the best possible result for a company’s investment."

OSHA has proposed $193,000 in penalties against Howard Industries for 54 violations of federal safety rules at the company's two manufacturing locations in Laurel, Miss.

The producer of electrical power products is being cited with 36 serious violations and proposed penalties of $123,500 at its Pendorf Road plant, with an additional 15 serious violations and proposed penalties of $41,000 at its Eastview plant. The violations include failing to provide employees with proper protective equipment, and to provide machine guards and lockout-tagout procedures. Lockout/tagout refers to preventing accidental start-up of machinery during maintenance.

Two repeat violations with penalties of $27,500 are being proposed for violations similar to those noted during earlier inspections in 2007. Chemical containers lacked identification labels and chains used as slings for lifting loads were shortened using makeshift measures rather than reducing the number of links.

One citation with a $1,000 penalty has been proposed for the company's failure to make material safety data sheets (MSDS) readily accessible to employees in their work area. A MSDS provides both employees and emergency personnel with information that is of particular use if a spill or other accident occurs.

"It is unconscionable for an employer to tolerate serious injuries, including amputations, as just a cost of doing business, rather than get out into the production areas and fix these numerous problems before employees get injured," said Clyde Payne, director of OSHA's Jackson Area Office.

The company has 15 business days to contest the citations and proposed penalties before the independent Occupational Safety and Health Review Commission.
The following is a press release from Electrophysics

An article in Processing Talk, asks industries in the U.K. "How do plants protect operators from Arc Flash?"

The article announces an arc flash survey to be conducted by TAS. The purpose of the survey is to assess the level of knowledge about Arc Flash hazards in U.K. industry, and to understand what plant operators are doing to mitigate the possible dangers and protect their workforce.

The article states:

"Initially the survey is being conducted by mailing the questionnaire to UK engineers in industries that are higher power users, (the mailing will go out in June) and there is also an on-line survey form on the TAS website, http://www.tas.co.uk/researcharcflash.

Respondents from overseas are welcome, but their experiences, attitudes and knowledge of arc flash hazards may be reported separately, to see and identify where differences exist compared to UK practice."

We will follow what happens with this survey and report on the results when they are available.
The following is a press release from LumaSense Technologies. They are a provider of sensor instrumentation for "monitoring, detecting, analyzing and measuring."

Broadcast date: Tuesday, June 3rd 2008
Broadcast Time: 11:00 AM PDT (2:00 PM EDT)
Speakers: Lowry Eads, Lowry Eads & Associates (Lanny Floyd, Dupont)
Hosted by: Brett Sargent, LumaSense Technologies ( John Snell, The Snell Group)

Most of us know that the words "Arc Flash" mean something serious. But, most of us do not know how dangerous an Arc Flash can be. Some things to consider are:

• There are approximately 2,000 Arc Flash events that occur in the United States every year
• Temperatures can reach 35,000°F in less than 1 second
• When copper vaporizes, a dynamite like explosion will occur

So, now that we have your attention, Arc Flash events can be minimized and avoided if you understand safety standards and adhere to published requirements. Documents such as NFPA 70E can help save lives and avoid catastrophic incidents.

Safe maintenance practices, knowing what to look for, thermal imaging of electrical switchgear using safe equipment and protective gear can all help.

Join us on Tuesday, June 3rd 2008 in this informative web seminar "Arc Flash Avoidance and NFPA 70E Compliance" to understand what an Arc Flash is and safety standards you should follow to save lives.

An article in today's online edition of Consulting-Specifying Engineer by Nicholas Chalhoub, Senior Electrical Engineer with CH2M HILL, is called "An Arc Flash Primer".

As most other articles about arc flash do, Mr. Chalhoub begins this article with an explanation of what arc flash is. I found it refreshing that he began his description of arc flash with the statement "The primary cause of arc fault is human error." He then describes how human error leads to arc flash and how arc flash hazards can be reduced.

The next topics are proper design, preventative maintenance and arc flash calculations. He discusses the goals and objectives of arc flash calculations and provides an example calculation. He then points out:

"After these calculations are generated, the arc flash and shock hazard tags must be printed and placed on the specified equipment. The flash hazard boundary, flash hazard, and the category type should be listed on the tag. Many maintenance and safety personnel have been requesting that the limited, restricted and prohibited approach be listed also."

In today's issue of Plant Engineering Live Michael Stuart of Fluke Thermal Imaging talks about using themal imaging to both detect hazards and pinpoint problems. The article is called Teaching An Old Dog New (Electrical) Tricks - Too many people have been injured by attempting to measure voltage on a circuit they thought was dead. Using thermal imaging avoids this deadly contact.

The article points out the capabilities of thermal imaging and suggests appropriate applications:

"When choosing between an infrared thermometer and a thermal imager, the choice is situational. Most technicians now carry a small infrared thermometer in their pocket for on-the-go checks. However, the infrared thermometer gives you only a 'spot' temperature reading. If you know what you’re looking for, infrared may be enough. But if you’re hunting an elusive problem, a full thermal map of the entire unit is more effective."

He provides a list of common components that are typically inspected using thermal imagers and also gives a list of typical reasons for temperature hotspots or deviations. Both of these can serve as useful memory jogger checklists.

Joseph Deane is principal owner of KTR Associates, spoke about arc flash at the Electric Power Conference this morning. Mr. Deane has over 25 years of experience as an Electrical Engineer, Project Manager, and Executive, working in both the industrial and utility business sectors.

The following is an abstract of his presentation:

The NFPA 70E standard was created at the request of OSHA in 1979 to recognize the difference between design and workplace safety. The National Electric Code (NEC) provides the installation (design) standard while the NFPA 70E is the workplace safety standard.

NFPA 70E describes employer responsibilities and recommendations on topics such as employee training, safety-related work practices, tagout procedures, calculating flash protection boundaries and PPE requirements. The current standard recognizes arc flash as a serious hazard and establishes PPE requirements that apply when working around energized equipment.

Why is the NFPA-70E Standard Important? Because following the NFPA-70E standard may save a life. Hazardous arc flashes can occur in any electrical device in which energy is high enough to sustain an arc. The heat exposure due to an electrical arc can produce first-degree burns, permanent blindness, or even death.

In an effort to reduce the extent of potential injuries NFPA-70E specifies boundaries within which flash protection (PPE) is required.

The National Safety Council estimates that an average of more than one fatality a day occurs while working around electrical equipment. Of these fatalities, more than half occurred while working on energized equipment rated 600 volts or below. In addition, five to ten electrical “arc flashes” occur in the workplace everyday. The medical costs for an individually exposed to an electrical arc flash is around $12 to $20 million.

Employers need to include both shock and arc hazard identification in their safety programs.

When working on electrical apparatus (switchgear, panelboards, motor control centers, etc.) the incident energy or available fault current to produce an arc flash needs to be clearly identified on each respective enclosure or piece of electrical equipment. As a part of that label, when employees must work within the flash protection boundary, it is important to include the incident energy. Producing a Flash Hazard Analysis can do this.

Does OSHA recognize the NFPA 70E? Absolutely. OSHA has recently updated their electrical standards to reflect the latest in both the NEC and NFPA 70E standard. OSHA will cite companies for non-compliance with 29 CFR 1910.335(a)(1)(i) which requires the use of protective equipment when working where a potential hazard exists and 29 CFR 1910.132(d)(1) which requires the employer to provide an assessment of the workplace for hazards and the need for personal protective equipment.

OSHA also utilizes the “General Duty Clause” which states, "each employer shall furnish to each of its employees a place of employment that is free from recognized hazards that are likely to cause death or serious physical harm."

The following is a press release from OSHA dated April 14, 2008.

OSHA cites DCS Sanitation Management Inc. for multiple safety and health violations following an electrocution death.

KANSAS CITY, Mo. -- The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) has cited DCS Sanitation Management Inc. for 10 alleged violations of federal safety and health standards following the Oct. 12, 2007, death of an employee at a Springfield, Mo., poultry processing facility.

An employee of Cincinnati, Ohio-based DCS Sanitation Management, working to sanitize poultry processing equipment, was electrocuted when the equipment's conductive surface became energized.

"Our inspection revealed multiple violations of OSHA's electrical standards," said Charles E. Adkins, OSHA's regional administrator in Kansas City. "It is imperative that employers remain committed to keeping the workplace safe at all times."

An alleged willful violation addresses hazards associated with the company's failure to ensure employees are removed from equipment hazard areas, all tools are removed, and equipment is operationally intact prior to its release from lockout/tagout safeguards and employee use. Lockout/tagout refers to preventing accidental start-up of machinery during maintenance. Willful violations are those committed with an intentional disregard of, or plain indifference to, the requirements of the Occupational Safety and Health Act and regulations.

An alleged repeat violation addresses a hazard associated with the lack of suitable facilities for quick drenching and/or flushing of the eyes and body in the event of an emergency when employees were working with injurious corrosives. Repeat violations are issued when an employer previously has been cited for the same, or a substantially similar, violation that has become a final order.

Alleged serious violations address the following hazards: failure to ensure electrical equipment was free from recognized hazards; failure to ensure the means of grounding machines and equipment was continuous and effective; enclosures for electrical components in wet environments that were not waterproof; failure to provide all flexible cords with a strain relief; failure to provide a standard guardrail system for every floor opening or platform above dangerous equipment; failure to provide and/or require the use of appropriate eye and face protective equipment; and allowing the consumption of food and beverages in areas exposed to toxic chemicals.

An other-than-serious violation addresses the employer's failure to report the fatal accident to the nearest OSHA area office within the required eight hours of occurrence. The agency's proposed penalties for all violations total $124,500.

DCS Sanitation Management Inc. has 15 business days from receipt of the citations and proposed penalties to comply, request and participate in an informal conference with OSHA's area director, or contest the citations and penalties before the independent Occupational Safety and Health Review Commission.

The Texas Christian University Daily Skiff (the student newspaper) reports in today's edition that two university employees were injured by an arc flash. The article reports that:

"Two physical plant employees were injured Wednesday morning in an electrical accident in the basement of Tandy Hall, university officials said."

"One employee who suffered injuries to his eyes and forearm was still in the hospital late Wednesday, and the other, who injured his knee while moving to avoid the shock, was treated and released, said Tracy Syler-Jones, associate vice chancellor for marketing and communication."

There had been a power outage and the two employees were working to start a backup generator. This incident should make us aware that we must always be alert to the possibility of an arc flash when working with electrical equipment. My guess is that the two workers who were injured never even considered the possibility of an arc flash. Training, proper labeling, and the use of PPE are three pillars that can not be ignored or forgotten.
Square D Schneider Electric has released another video on their website which is also available for online viewing or download. The new video is called "Solving the Puzzle of Electrical Safety Compliance".

This new video provides a basic seminar about electrical safety compliance which thoroughly explains the details about electrical hazards and NFPA 70E, and how OSHA enforces this important electrical safety standard. The non-technical treatment is suitable for anyone who is responsible for, or concerned with electrical safety.

The running time for this video is approximately 75 minutes. It is available in four formats (two for streaming video and two for download). Each option has two file sizes to accommodate different internet connection speeds. Because the video length is 75 minutes, you may prefer to use one of the two download options that are available. Download will take several minutes to complete, depending on your internet connection quality.

Norcross is uniquely positioned in a number of core vertical segments including General Safety and Preparedness (respiratory protection; protective footwear; hand protection; eye, head, face and ear protection; first aid; and fall protection); Fire Service (firefighter turnout gear, footwear, helmets, gloves and other accessories); and Electrical Safety (gloves and sleeves, lineman equipment and arc flash protection). Norcross sells its products under trusted, long-standing and well-recognized brand names, including North, KCL, Fibre-Metal, Morning Pride, Pro-Warrington, Salisbury and Servus.

“Becoming a part of Honeywell is a terrific opportunity for our business, customers and employees.

The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) has cited two contractors - J&S Carpentry of Columbia, Maine, and Irving Equipment Inc. of Hampton, N.H. - for 15 alleged violations of safety standards following the electrocution death of an employee at a Hermon, Maine, residential construction site.

On Sept. 12, 2007, an Irving crane contacted an energized 7,200 volt overhead power line as two J&S Carpentry employees were attempting to attach the crane's rigging equipment to a section of a modular home that was being constructed at 28 Lily Lane in Hermon. One of the employees was killed and the other seriously injured by the electric current.

OSHA's inspection found that the crane was being operated within 10 feet of the power line, which had not been de-energized beforehand, as required. The two contractors face a combined total of $121,500 in proposed fines.

"The basic safeguards designed to prevent just this sort of accident were ignored here, with fatal results," said William Coffin, OSHA's area director for Maine. "De-energizing the power line and maintaining a safe working distance from it would have prevented this death and injury."

J&S Carpentry, for whom the employees worked, was issued two willful citations for allowing employees to work in close proximity to the energized power line and for not protecting employees against fall hazards. OSHA also issued the company four serious citations for a lack of on-site medical attention; absence of hardhats and electrical warning signs; and ladder hazards. J&S Carpentry faces a total of $32,000 in proposed fines for these conditions.

Irving Equipment, which owned and operated the crane, has been issued three repeat citations for operating the crane in high winds, inadequate support for the crane's outriggers, and not inspecting the job site to identify and correct these and other hazards. OSHA had cited the company in May 2005 for similar hazards at a Freeport, Maine, job site.

Irving Equipment also has been issued six serious citations for operating the crane within 10 feet of the power line; not operating the crane in accordance with the manufacturer's specifications and industry standards; and lack of fall protection, hardhats, on-site medical attention and an electrical warning sign. Irving Equipment faces a total of $89,500 in proposed fines for these conditions.

OSHA defines a willful violation as one committed with plain indifference to or intentional disregard for employee safety and health. A serious citation is issued when death or serious physical harm is likely to result from a hazard about which the employer knew or should have known.

Each company has 15 business days from receipt of its citations to contest them before the independent Occupational Safety and Health Review Commission. The inspection was conducted by OSHA's Bangor District Office.
