Arc Flash Hazards: Ensure your facility follows the latest standards to provide maximum safety around equipment and other electrical hazards.

DEFINITIONSWhat is an Arc Flash?An arc fl ash is a rapid, explosive discharge of electrical energy that usually results from a short circuit fault. Metal vaporized by the 5,000+ degree temperatures of an arc fl ash produces a high-temperature plasma. A shock-wave blast can propel metal shrapnel at high velocities in many directions. An arc fl ash can occur in very little time. Explosions have been known to occur in as little as 1/1000 of a second. The event is unexpected, violent and deadly.

The potential for injury can be reduced using various electrical safety tools and techniques. Remote breaker racking, remote door opening and closing and wearing the proper personal protective equipment (PPE) all offer improved safety. A key element in any arc fl ash safety program is good visual communication. Using labels and signs to warn workers, emergency responders and others of a potential arc fl ash hazard is critical safety information and saves lives.


DEFINITIONS

Limited Space

Restricted Approach Boundary

Restricted SpaceAny point on an exposed, energized electrical conductor or circuit part

Prohibited Space

Prohibited Approach Boundary

Defi nitions of Terms (from NFPA 70E, 2012 Edition)The following terms are frequently found on arc fl ash labels and signs.

Nominal System Voltage (NSV) – The NSV is normally the voltage required by the largest loads in a system. Common industrial values are 120, 208, 220, and 480 volts. This measurement can be VAC or VDC and required by 2012 NFPA 70E (130.5(C)) to be displayed on arc fl ash labeling.

Arc Flash Boundary – The arc fl ash boundary is the distance at which a person is likely to receive a second degree burn. The onset of a second degree burn is possible when the skin receives 1.2 cal/cm2 of incident energy. Calculations based on 2012 NFPA 70E Annex D.7.5. This measurement is required by 2012 NFPA 70E (130.5(C)) to be displayed on arc fl ash labeling.

Available Incident Energy at a Working Distance – This is the energy per unit area on a surface located at the normal working distance from the potential arc fault. The incident energy is most commonly measured in units of calories per square centimeter. Second degree burns occur at an energy level of approximately 1.2 cal/cm2.

Required Level of PPE – The Personal Protective Equipment required is dependent on the incident energy at every point a person may perform work on energized equipment. An electrical engineer or other qualifi ed person should cover all parts of the body that may be exposed to an arc fl ash. This could include boots, gloves, fl ame resistant clothing, safety glasses, etc. Hearing protection and leather gloves are required for all hazard risk categories (Tables 130.7(C)(14)).

Hazard Risk Category (HRC) – A general classifi cation of hazard involved in performing specifi ed tasks. HRC typically ranges from zero to four, with zero denoting minimum-risk activities and four denoting high-risk activities. The NFPA provides a recommended list of PPE for each HRC in Table 130.7. HRC levels are not associated with a specifi c measurement of cal/cm2 by the NFPA, but rather a defi ned list of PPE.

Shock Protection Boundary (Not Required) – Limited Approach Boundary (Annex C.1.1 and C.1.2.2)

This boundary may only be crossed by a qualifi ed person. An unqualifi ed person, wearing appropriate PPE may cross if accompanied by a qualifi ed person. Becoming qualifi ed requires special training.

– Restricted Approach Boundary (Annex C.1.2.3)This boundary may only be crossed authorized management using adequate shock prevention equipment and techniques.

– Prohibited Approach Boundary (Annex C.1.2.4)This boundary may only be crossed by a qualifi ed person that has the same level of protection required for direct contact with live parts.

As the distance between a person and the exposed energized conductors or circuit parts decreases, the potential for electrical accidents increases. The NFPA defi nes eight boundaries around an arc fl ash fault.

Limits of approach (NFPA 70E-2012)


EVALUATION – FACILITY INSPECTION

FACILITY INSPECTIONS: Stay compliant with today’s standards and inspect facilities regularly to assist in arc fl ash safety.

NOTE: Arc fl ash calculation is not an exact science. Always

use caution and multiple methods to verify results.

Incident energy is a calculation that determines the radiated heat falling on the surface, produced by an arcing fault. Although no single method can fully calculate an arc fl ash hazard, it is recommended that IEEE 1584-2002 be used as the primary calculation method - especially for determining fl ash protection boundaries. IEEE 1584, “Guide For Performing Arc Flash Hazard Calculations,” provides the equations and methods used to calculate the incident energy level a worker could be exposed to in a measurement of cal/cm2. If IEEE 1584 is not available in your facility, then the NFPA 70E-2012 is the next best option.

Tables 130.7(C)(15)(a) and 130.7(C)(16) from NFPA 70E-2012 are popular references for determining exposure levels and required PPE. However, these tables are based on assumptions using engineering principles about electrical systems. Each table includes notes to help you determine whether an electrical system falls within the engineering principles described. At a minimum, electrical equipment carrying 50 volts or higher should always display a label with OSHA required information. OSHA 29 CFR§1910.303 requires employers to mark electrical equipment with descriptive markings, including the equipment’s voltage, current, wattage, or other ratings as necessary.

There are a number of calculation methods available to help you determine arc fl ash boundaries. IEEE 1584-2002 and NFPA 70E-2012 are the most popularly used. IEEE 1584 is generally accepted as the recommended method for most arc fl ash analysis calculations because of its comprehensiveness. The NFPA 70E version is easier to use and offers quick references to predefi ned articles and tables. Having both guides to reference, however, is always going to be the best option. This way you have the largest number of options available to suit individual needs.

Conduct an inspection of your facility to determine the need for new and replacement arc fl ash labels.

When evaluating your facility, pay attention to:▪ Existing labels

▫ Are they still legible? (Damaged, deteriorated, etc.)

▫ Are they accurate? (Proper calculations, boundaries, PPE, etc.)

▪ Equipment without labels

▪ New equipment

▫ Does the new equipment pose an arc fl ash danger?

▫ Have boundaries been calculated?

▪ Areas where maintenance has been performed

▪ Traffi c areas

▪ Areas from which people should be excluded due to arc fl ash hazard

Also be sure to note the date of your last arc fl ash analysis. NFPA 70E Article 130.5 states you must re-evaluate an arc fl ash analysis at least every 5 years. If this re-evaluation shows a change, your labels need to be updated.

General facility inspections are not just voluntary, OSHA requires employers to assess hazards in the workplace.

OSHA 29 CFR 1910.132(d)(2)The employer shall verify that the required workplace hazard assessment has been performed through a written certifi cation that identifi es the workplace evaluated; the person certifying that the evaluation has been performed; the date(s) of the hazard assessment; and, which identifi es the document as a certifi cation of hazard assessment.

Recording the information listed will help you meet this OSHA requirement in your facility.

ELECTRICAL EQUIPMENT

TRANSFORMER IDENTIFICATION

Qualifying Electrical Equipment

IEEE 1584-2002In general, electrical equipment qualifying for an arc fl ash analysis are also locations where arc fl ash labeling must be posted. IEEE 1584 states that, “Equipment with less than 240 volts need not be considered unless it involves at least one 125 kVA (kilo-volt-amps) or a larger low-impedance transformer in its immediate power supply.” The same guide also states that an, “arc-fl ash hazard need only be considered for large 208 volt systems. Systems fed by transformers smaller than 125 kVA should not be a concern.”

The prevailing interpretation of IEEE 1584: An arc fl ash analysis shall be performed on equipment with 208 volts or greater and fed by a transformer with 125 kVA and greater.

Keep in mind, these standards are considered the bare minimum for facility safety and many organizations supersede IEEE 1584 standards. Commonly used, self-imposed standards, require analyzing and labeling equipment with 208 volts or greater and fed by a transformer with 75 kVA and greater.

NFPA 70E-2012The 2012 NFPA 70E standards identify fi ve specifi c types of electrical equipment requiring arc fl ash labeling. The equipment identifi ed is not located in dwellings, meets the minimum IEEE 1584 requirements for an arc fl ash analysis and is likely to require examination, at the very least, while energized.

Newly specifi ed pieces of electrical equipment include:

Equipment ResearchAlways wear the highest level of PPE your equipment may potentially require while researching equipment. For many facilities, this means wearing a 40-calorie arc rated suit, hearing protection and arc rated gloves while performing examinations. Start by photographing each potential piece of equipment that is a candidate for an analysis. Then document its voltage and facility location onto a copy of your facility’s blueprints or map.

If a piece of equipment isn’t labeled with voltage, the primary voltage may be labeled on the back or elsewhere on the equipment. If the voltage isn’t provided on the equipment, research your facility’s single-line-drawings and other electrical documentation. Many times, this information will tell you what voltage each piece of equipment is carrying. Once you know the primary voltage for each piece of equipment, you can eliminate equipment carrying less than 208 volts from your list.

If you don’t know the transformer size for your equipment, you can often use the secondary voltage as your guide. However, there may be exceptions. Research your equipment documentation for verifi cation. Generally, transformer sizes are based on the total connected load on the secondary side. Many times you can do so by fi nding the primary voltage of the downstream piece or pieces of equipment. Use this total amount to determine your transformer size by selecting the next size up from the following list:*

*Most commonly available transformers (GE, Square D, Eaton, etc.)

As an example, a piece of equipment may be delivering all of its secondary power to a downstream piece of equipment or device with a primary of 120 kVA. In the example shown, you could estimate the transformer is likely 150 kVA since this is the next size up from a 120 kVA secondary.

Once you have the voltage and transformer size, you should now know if your piece of equipment qualifi es for analysis and labeling.

EVALUATION

▪ 15 kVA ▪ 30 kVA ▪ 45 kVA ▪ 75 kVA

▪ 112.5 kVA ▪ 150 kVA ▪ 225 kVA ▪ 300 kVA

▪ Switchboards ▪ Panelboards ▪ Industrial control panels

▪ Meter socket enclosures ▪ Motor control centers

The equipment listed in the NFPA 70E-2012 is provided as examples of commonly used pieces of electrical equipment. Similar pieces of equipment, meeting the NFPA/IEEE qualifi cations, would of course, require the same treatment.

Transformer: Remember to account for all secondary electricity. Equipment and transformers may supply multiple secondary devices.


ARC FLASH LABELS: The DuraLabel PRO 300 & 9000 are great printers for customizing Arc Flash labels on demand and at a low price.

*Exception: Labels applied prior to September 30, 2011, are acceptable if they contain the available incident energy or required level of PPE.

LABEL CREATIONThe 2012 NFPA 70E now requires arc fl ash labels to display a list of defi ned information. These new requirements help bring uniformity to arc fl ash labeling so similar information is used to describe this hazard throughout the U.S.

Signal Word UsageIn most arc fl ash labeling, a Danger or Warning signal word is used to describe this hazard. Exceptions are when an overriding federal, state or local code, standard, regulation or guideline specifi es a different signal word than ANSI specifi es. ANSI defi nes how each word should be used (ANSI Z535.4-2011§4.14.2 and §4.14.3). The Danger signal word is reserved for, “... a hazardous situation that, if not avoided, will result in death or serious injury. The signal word is to be limited to the most extreme situations.” The Warning signal word is reserved for, “a hazardous situation that, if not avoided, could result in death or serious injury.”

Generally, arc fl ash locations presenting a hazardous situation that, if not avoided, will result in death or serious injury, are also locations where no known PPE exists to safely work while equipment is energized. Organizations may wish to use the maximum level of PPE available, generally greater than 40 calories, to set this as their cut off for Danger. As an example, if a facility can only provide workers with PPE rated for a maximum of 50 calories, that

ANSI Z535The NFPA relies on many of the same design standards as OSHA and similar agencies and associations for safety labeling. ANSI Z535 sets these standards to help bring uniformity to all labeling and improve recognition by workers, emergency responders and anyone else who must easily identify what a label means from a safe distance. ANSI compliant arc fl ash labels generally contain fi ve elements.

would be the cut off. Danger labels, in this example, would be reserved for use at arc fl ash locations where greater than 50 calories of incident energy are possible. The Warning signal word would then only be used at arc fl ash locations where 50 calories or less are possible. The Caution signal word is also an option, but should only be used where an arc fl ash analysis determined there is no risk of death. Therefore, Caution signs should only be displayed at locations where an arc fl ash is not possible.

Each signal word uses a specifi c color scheme when displayed on an arc fl ash label. The Danger signal word is white on red. Warning is black on orange and Caution is black on yellow.


Safety Alert Symbol The triangle/exclamation point symbol. The safety alert symbol must precede the signal word and the base shall be on the same horizontal line as the base of signal word letters. The height of the symbol shall be equal to or exceed the signal word letter height. For Danger, the triangle shall be fi lled with white and have a red exclamation mark inside. The triangle on a Warning label shall be fi lled with black and contain an orange exclamation mark. Caution labels shall have an all black triangle with a yellow exclamation mark.

Signal Word PanelThe colored panel the signal word appears on. This panel always appears horizontally across the top of the label. For arc fl ash Danger labels the panel shall be red. For Warning the panel should be orange and Caution labels should have a yellow panel.

The position of the Safety Alert Symbol must be aligned with the base of the safety word. The height of the symbol should be equal to or exceed the letter height of the associated signal word. Both the Safety Alert Symbol and Signal Word should then be centered.

Message Panel The white or black background beneath the signal word panel. The message panel in an arc fl ash label is where the safety message, analysis information and PPE requirements are printed. The message panel can be either black or white. A white panel requires black text and a black panel requires white text. The white message panel is recommended for most arc fl ash applications, since it is generally easiest to see.

What should be included on a label used for these applications?Arc fl ash labels should alert workers to the seriousness of the hazard and clearly state the information necessary to safely work inside and around an arc fl ash boundary. Use the appropriate signal word in the label’s signal word panel when identifying equipment meeting IEEE 1584 analysis requirements.

LABEL CREATION

Arc Flash Label Elements In addition to signal word requirements, ANSI Z535.4 sets standards for general label design elements used in arc fl ash Danger, Warning and Caution labeling. The following design elements are required by ANSI Z535.4 standards:

DANGERSafety Alert Symbol Signal Word Panel

2012 NFPA 70E requires labels to display the following: 1. Nominal system voltage

2. Arc fl ash boundary

3. At least one of the following:

(a) Available incident energy and the corresponding working distance

(b) Minimum arc rating of clothing

(c) Required level of PPE

(d) Highest Hazard/Risk Category (HRC) for the equipment

Message Panel


LABEL CREATION

Canadian Arc Flash Labeling (2012 CSA-Z462)Although date of analysis is commonly displayed on arc fl ash labels used in the U.S., it is not required by the NFPA. The benefi t of including this date on U.S. arc fl ash labels is to inform workers how long its been since an analysis has been completed. Workers can then confi rm the validity of the analysis by researching facility electrical documentation and history, before exposing themselves to the hazard.

WARNING LABELS: Die-cut warning labels make application easy.

Understanding Arc Flash PPE One of the most important factors to understand about arc fl ash labeling is the relationship it has with the arc fl ash PPE. Practically everything now required by the NFPA 70E-2012 on a label relates to PPE selection. Ensure your facility has adequate PPE to safely work on or around the equipment that must be analyzed. As an employer, you have legal responsibilities to fulfi ll.

NON-COMPLIANT ARC FLASH LABEL DESIGN:

Since a message panel is required, all red Dangersigns and tags and all orange Warning signs and tags are no longer compliant with NFPA and ANSI standards.*

An example of a non-compliant, all orange Warning arc fl ash label*ANSI.4-2011, §7.3

The Canadian Standards Association (CSA) bases many of their standards on the 2012 NFPA 70E and, for the most part, they are very similar. The only difference between CSA-Z462-2012 and 2012 NFPA 70E is the additional arc fl ash labeling requirement for date of analysis. This means, in addition to 2012 NFPA 70E requirements, you only need to display the date your analysis was performed on to comply in Canada.

OSHA 29 CFR 1926.95(a)“Protective equipment, including personal protective equipment for eyes, face, head, and the extremities, protective clothing, respiratory devices, and protective shields and barriers, shall be provided, used, and maintained in a sanitary and reliable condition wherever it is necessary by reason of hazards of processes or environment, chemical hazards, radiological hazards, or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation, or physical contact.”

OSHA 29 1926.416(a)(1)“No employer shall permit an employee to work in such proximity to any part of an electric power circuit that the employee could contact the electric power circuit in the course of work, unless the employee is protected against electric shock by de-energizing the circuit and grounding it or by guarding it effectively by insulation or other means.”

Layering PPE is a method the NFPA often promotes to increase the protective resistance a piece of clothing has against incident energy. Arc rated clothing can be grouped by displaying multiple arc rated pieces on a label. As an example, one of the most popularly used PPE in electrical work is the “40 calorie suit.” Layering additional pieces of arc rated clothing under this suit helps increase its protective resistance so higher calorie equipment can be safely worked on or around.

LABEL CREATION


LOCATION OF LABELS: It is critical labels are placed appropriately to be seen from normal approach and applied correctly for longevity.

LABEL PLACEMENT: Labels should be placed on or close to the appropriate system or equipment.

LABEL PLACEMENTLabels Should Be Placed:▪ On or close to the appropriate system or equipment.

▪ To be visible from the point of normal approach.

Removing Old LabelsWhen removing labels, use extreme caution. Labels may be removed by carefully scraping them off with a putty knife. However, with strong adhesive labels such as those provided by DuraLabel, this can be a labor intensive process. A heat gun might be considered as a means to speed up the process.

For some applications, a powered wire brush can be used to quickly remove labels. The use of this type of tool must take into consideration the type of surface the label is applied to and whether that surface will be damaged.

LABEL MAINTENANCELabels should be properly maintained to ensure legibility and readability. Under normal conditions labels will last fi ve to seven years. Environmental conditions can result in a shorter, or a longer life.

Labels should be inspected periodically and replaced if they are missing or have deteriorated beyond legibility. Accumulation of debris, grease, oil, or other materials should be cleaned off.

Labels are only useful if they are visible. DuraLabel offers a wide selection of chemical resistant supplies, therefore

solvents and cleaning agents may be used when necessary to clean off dirt, grime, oil, etc… If cleaning is not possible and the label is not readable, replace the existing label.

Set up a schedule to reevaluate your facility. Refer to the section “Evaluation – Facility Inspection” on page 4 of this guide for help.

Tagout example procedure (lockout elements not included):1. Provide all employees, and others who might be in the area,

with tagout safety instruction and explain its signifi cance. All persons installing tagout shall sign their names and provide a date on the tag.

2. Inspect current diagrams, tags, labels and signs. Identify and locate all circuit breakers and switches to determine power is interrupted by a physical break and not de-energized by a circuit interlock. Create a list of each to be tagged.

3. Inspect circuit breakers and switches to determine adequacy of their interrupting ability. Determine if it will be possible to verify a visible open point, or if other precautions will be necessary.

4. Inspect other work activity to identify where and how other personnel might be exposed to sources of electrical energy hazards. Review other energy sources in the physical area to determine employee exposure to sources of other types of energy. Establish energy control methods for control of other hazardous energy sources in the area.

5. Test each phase conductor or circuit part with an adequately rated voltage detector to verify they are de-energized. Test the voltage detector to ensure proper operation.

6. Where the possibility of induced voltage or stored electrical energy exists, create labels that call for grounding the phase conductors or circuit parts before touching them. Post these labels at visible locations wherever this hazard exists. Where it could be reasonably anticipated that contact with other exposed energized conductors or circuit parts is possible, create labels that call for applying ground connecting devices. Post these labels at locations wherever this hazard exists.

7. Notify employees a tagout system is going to be implemented and explain the reason. A qualifi ed employee should lead this implementation. The leader should be knowledgeable of the circuit breaker and switches for all sources of electrical energy and the location of all sources of stored energy as well as hazards associated with electrical energy.

8. If the electrical supply is energized, the implementation leader shall de-energize and disconnect the electrical supply and relieve all stored energy.

9. Tagout all disconnecting means with tagout devices. Open, block or remove any additional circuit elements.

10. Use a voltage-detecting instrument. Verify the instrument is properly functioning before and after testing for absence of voltage.

11. Where required, install a grounding device on the phase conductors or circuit parts to eliminate induced voltage or stored energy before touching them. Apply devices rated for the available fault duty.

12. The equipment, electrical source or both are now tagged out.

When tagouts are ready for removal:1. Visually verify the job or task is complete. Remove all tools,

equipment and unused materials.

2. Notify all personnel involved that a tagout is complete and the electrical supply is being restored. All workers must stay clear of the equipment during startup.

3. Perform quality control tests or checks on repairs. The person who installed the tagouts should then remove tagouts.

.

NOTE: Employers must develop their own procedure based on the needs of their specifi c application.

Nominal System Voltage (NSV) The NSV is normally the voltage required by the largest loads in a system. Common industrial values are 120, 208, 220 and 480 volts. This measurement can be VAC or VDC and is required by 2012 NFPA 70E (130.5(C)) to be displayed on arc fl ash labeling.

Arc Flash BoundaryThe arc fl ash boundary is the distance at which a person is likely to receive a second degree burn. The onset of a second degree burn is possible when the skin receives 1.2 cal/cm2 of incident energy. Calculations based on 2012 NFPA 70E Annex D.7.5. This measurement is required by 2012 NFPA 70E (130.5(C)) to be displayed on arc fl ash labeling.

Available Incident Energy at a Working DistanceThis is the energy per unit area on a surface located at the normal working distance from the potential arc fault. The incident energy is most commonly measured in units of calories per square centimeter. Second degree burns occur at an energy level of approximately 1.2 cal/cm2. You have the choice to display available incident energy at a working distance to fulfi ll one of three 2012 NFPA 70E labeling requirements (130.5(C)) as indicated in #3 at top.

Minimum Arc Rating for ClothingThe measurement used to determine Hazard Risk Category (HRC) can be used for the minimum arc rating for clothing. However, organizations may choose to exceed NFPA 70E requirements and give a higher level of PPE than the HRC calls for. The arc rating for a particular clothing system can be obtained from the arc rated clothing manufacturer. You have the choice to display minimum arc rating for clothing to fulfi ll one of three 2012 NFPA 70E labeling requirements (130.5(C)) as indicated in #3 at top.

Required Level of PPEThe Personal Protective Equipment required is dependent on the incident energy at every point a person may perform work on energized equipment. An electrical engineer or other qualifi ed person should perform the calculations that determine the incident energy. The appropriate PPE should cover all parts of the body that may be exposed to an arc fl ash. This could include boots, gloves, fl ame resistant clothing, safety glasses, etc. Hearing protection and leather gloves are required for all hazard risk categories. (Tables 130.7(C)(14)) You have the choice to display required level of PPE to fulfi ll one of three 2012 NFPA 70E labeling requirements (130.5(C)) as indicated in #3 at top.

Hazard Risk Category (HRC)A general classifi cation of hazard involved in performing specifi ed tasks. HRC typically ranges from zero to four, with zero denoting minimum-risk activities and four denoting high-risk activities. The NFPA provides a recommend list of PPE for each HRC in Table 130.7. HRC levels are not associated with a specifi c measurement of cal/cm2 by the NFPA, but rather a defi ned list of PPE. You have the choice to display hazard risk category to fulfi ll one of three 2012 NFPA 70E labeling requirement (130.5(C)) as indicated in #3 at top.

Shock Protection Boundary (Not Required)• Limited Approach Boundary (Annex C.1.1 and C.1.2.2) This boundary may only be crossed by a qualifi ed person.

An unqualifi ed person, wearing appropriate PPE may cross if accompanied by a qualifi ed person. Becoming qualifi ed requires special training.

• Restricted Approach Boundary (Annex C.1.2.3) This boundary may only be crossed by a qualifi ed person that has

a documented plan approved by authorized management and uses adequate shock prevention equipment and techniques.

• Prohibited Approach Boundary (Annex C.1.2.4) This boundary may only be crossed by a qualifi ed person that has the

same level of protection required for direct contact with live parts.

Requirements for Arc Flash Label ComplianceThe 2012 edition of NFPA 70E requires labels used for specifi c applications to include standardized information

Electrical equipment such as switchboards, panelboards, industrial control panels, meter socket enclosures and motor control centers that are in other than dwelling units and are likely to require examination, adjustment, servicing, or maintenance while energized must contain a check list with*:(1) Nominal system voltage(2) Arc fl ash boundary(3) At least one of the following:

a. Available incident energy and the corresponding working distanceb. Minimum arc rating of clothingc. Required level of PPEd. Highest Hazard/Risk Category (HRC) for the equipment

Method for calculating analysis data shall be documented.

NFPA 70E Article 130.5 states that an arc fl ash hazard analysis must be reviewed every 5 years or whenever a major modifi cation or renovation occurs.

*Exception: Labels applied prior to September 30, 2011, are acceptable if they contain the available incident energy or required level of PPE.
