NFPA Today

Lately there has been discussion about the topic of recertification in the fire service in some industry publications, and there seems to be some confusion or misperceptions about our recent activity. Here is the history and the current status.


In the summer of 2016, the Fire Protection Research Foundation (Research Foundation), the independent research affiliate of NFPA, received a request to conduct a study on fire services professional qualifications and recertification requirements. The proposal asked for a review of the existing processes that are in place for emergency personnel to demonstrate their level of competency against a certain credentialing benchmark. It also requested recommendations for implementing and enforcing a proficiency system on a local, state, and national level.


The Research Foundation undertook this project in 2018. This overall effort entailed two deliverables: (1) The research report which has been available online since September 2019, and (2) the workshop proceedings which have now been finalized and are available on the Research Foundation’s website.

The research project

The contractor for this project was FireTox, LLC. They were selected through the Research Foundation’s open RFP process in accordance with our policies, and were chosen to conduct the research with a goal of identifying, comprehending, and reviewing the current fire service training and certification climate. As part of the project, approaches used by parallel professions (EMS, law enforcement, nurses, and teachers) were assessed and a continuing education model was developed. Fire service members were then surveyed to determine how implementation of that model would impact them and their organization.

Findings foster workshop discussions


The new research report was used to facilitate conversation between interested stakeholders and fire service representatives at an October workshop at NFPA headquarters.


The following was considered during the workshop:


  • The evolution, status and anticipated direction of the ProQual system and JPR development
  • Current practices for maintaining fire and emergency personnel skill proficiency in North America
  • Clarification of the relevancy and applicability of the processes adopted in parallel professions
  • Identification, prioritization, and assessment of processes that could be implemented for fire and emergency services personnel
  • The creation of a recommended action plan to provide guidance to the ProQual infrastructure to meet the needs for today and the future


The goal was not to reach consensus on any of the issues that were discussed. Instead, the objective was to gather threshold information that can be used as guidance.


This project and workshop did not, and could not, change any information in any NFPA standard. Changes can only be made to NFPA documents through the Standards Development process.

NFPA 1000 Standard for Fire Service Professional Qualifications Accreditation and Certification Systems has just begun the next revision cycle. Several Public Inputs (recommended changes) were submitted for the next edition of NFPA 1000 by the stated closing date of November 15, 2019.

All recommended changes from the public will now be reviewed by the Technical Committee at their First Draft Meeting to be held January 27-28 in Orlando, Florida. Only at that point, during the First Draft meeting, will any proposed changes to NFPA 1000 be developed by the Technical Committee. Proposed changes to NFPA 1000 that pass ballot by the Technical Committee will then be open for public review and comment. The Technical Committee will ultimately meet in November 2020 to review and act on all submitted Public Comments during the Second Draft Meeting. It is anticipated that the next edition of NFPA 1000 will be the 2022 edition, which will be released in late 2021.

The Research Foundation also undertook a project on the topic of maintaining proficiencies for the fire service that entailed two deliverables – a research report and workshop proceedings which are available on the Research Foundation’s website.


With the number of electrical contact fatalities in the workplace being relatively flat since 2012 (average 146 fatalities with a range of 134 to 156), I decided to look into what the Bureau of Labor Statistics (BLS) database provides for the electrical parts contributing to these fatalities. Perhaps if more of us have knowledge of who and what are involved in electrocutions we can further reduce the number of fatalities. 

The 1980-1992 data from the National Institute for Occupational Safety and Health (NIOSH) National Traumatic Occupational Fatalities Report (May 1998) shows a high of 582 electrical contact fatalities in 1981. An average of 411 fatalities occurred over those dozen years with the construction industry accounting for a majority of the fatalities. The most frequent victims were linesmen, laborers, electricians and painters. Thirty-three percent of the electrocutions occurred at less than 600 volts. Of these low-voltage electrocutions, 54% occurred at household voltage levels (120-240 volts). Fatalities at all voltages were caused by: direct worker contact with an energized powerline (28%); direct worker contact with energized equipment (21%); boomed vehicle contact with an energized powerline (18%); improperly installed or damaged equipment (17%); conductive equipment contact with an energized powerline (16%). Over 60% of the electrical contact fatalities occurred by contact with overhead power lines.

The BLS database shows an annual average of 269 electrical contact fatalities between 1992-2010 with a high of 348 in 1994. Although listed differently, the construction industry still suffered the most fatalities over this period. The three leading causes of electrical contact fatalities were: contact with overhead power lines (43%), contact with wiring, transformers, or other electrical components (16%) and contact with electric current of machine, tool, appliance, or light fixture (10%). 

The BLS lists an annual average of 152 fatalities between 2011-2017 with a high of 174 fatalities in 2011. Once more the construction industry suffered the most fatalities. Recording of the fatalities and the equipment involved changed in 2011. Now power lines, transformers, and convertors are included in one category which accounted for 59% of the fatalities, followed by building electrical wiring (15%) and power cords, electrical cords, extension cords (10%) and switchboards, switches, fuses (8%). 

An encouraging note from this data is that there has been an annual decrease of 76% in electrical contact fatalities since 1982. Which not surprisingly began to decrease after the issuance and increased use of the first edition (1979) of NFPA 70E, Standard for Electrical Safety in the WorkplaceA discouraging statistic is that nearly 60% of the annual fatalities over 40 years have consistently been through contact with overhead wires. I looked through available NIOSH case studies to find out who the victims were. Electricians, linesmen, painters, grounds keepers, roofers, and tree trimmers are common victims. A majority of their fatalities involved the use of a ladder. Other victims include well drillers, dump and cement truck drivers, and boom truck operators. Most of these involved parking near or beneath overhead power lines then raising a portion of the truck. It is disturbing that awareness of the work area could be a simple way to cut electrocutions in the workplace nearly in half.

NFPA 70E, Standard for Electrical Safety in the Workplace as its title suggests, is for all employees who might be exposed to electrical hazards while performing their assigned tasks. However, many employers and employees tend to believe that it is written only for those in the electrical industry. This may be one reason for so many overhead power line fatalities occurring even though NFPA 70E has requirements specifically covering this scenario. Fatalities are occurring in trades that may be mistaken in the belief that an electrical safety program does not apply to them. It is foreseeable that employees from these other trades will be exposed to electrical hazards. A field, yard, roadway or rooftop is their work environment. Federal law mandates that an employer furnish to each of his employees’ employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees. If you are not in an “electrical trade” what does your employer do to ensure your electrical safety at your workplace?

Winter doesn’t officially start for another couple weeks, but looking out the window here in New England and many other parts of the country tells a different story. Snow is covering the ground, and each additional storm will pile it higher. With the cold, wintry weather brings an increased risk of carbon monoxide (CO) poisoning from blocked heating system combustion exhaust vents. The current (2018) edition of the Life Safety Code requires the installation of carbon monoxide detectors or alarms in certain occupancies with combustion equipment, including:

  • New assembly occupancies
  • New educational occupancies
  • New day-care homes
  • New and existing health care occupancies with fireplaces
  • New one- and two-family dwellings
  • New lodging or rooming houses
  • New hotels and dormitories
  • New apartment buildings
  • New residential board and care occupancies

Most of us, however, live in existing homes – defined as those constructed prior to the adoption of the current edition of the code – with older heating equipment and vent systems. It’s in these existing homes where the greatest risk lies. In 2005, seven-year-old Nicole Garofalo of Plymouth, Massachusetts died when a snow drift blocked the exhaust vent on her home’s heating system. Several months later, the state enacted Nicole’s Law in her memory, which requires all homes in Massachusetts with combustion equipment or enclosed parking to have carbon monoxide detection equipment. The law is enforced at the time a house is sold; fire department approval is required prior to the transfer. This exceeds the minimum requirements of the Life Safety Code, which does not require CO detection in existing homes. Kudos to Massachusetts for taking the lead on requiring relatively inexpensive, life saving protection where it’s needed most.

And what is the cost to provide this valuable protection in an existing home? I’ll offer myself as a case study. When I bought my house a few years ago, it met Nicole’s Law by having two plug-in CO alarms – one on each level. I just looked on my favorite online shopping site; a plug-in CO alarm goes for under $20. For under $100, you can protect a pretty good-sized home. Now, my house has a gas furnace, a gas stove, a gas fireplace, a wood-burning fireplace, and an attached garage; I wanted something more than a couple plug-in alarms. My house already had hardwired, interconnected smoke alarms that were due to be replaced. (Smoke alarms should be replaced every ten years or as directed by the manufacturer.) Instead of buying replacement smoke alarms, I bought combination smoke and CO alarms. Again, on my favorite online shopping site, a box of six hardwire combination carbon monoxide and smoke alarms with battery backup and voice warning goes for $168. I’m pretty handy so I did the installation myself. $168 was a small price to pay for the lives of me and my family.

If you’re reading this #101Wednesdays blog, I’m likely preaching to the choir. You already know about the dangers of CO poisoning and the need to keep combustion vents clear. Most people, however, don’t think like us. So as this holiday season approaches, think about your neighbors. Check to make sure their vents are clear. Maybe if they’re older, ask if you can help to clear them. Ask if they have CO alarms in their homes. If not, for $20 you could give a gift that’s much more thoughtful than a fruitcake.

See NFPA’s website for more details on CO, including safety tips and NFPA’s nonfire CO incident report.

Thanks for reading, and stay safe.

"The Magnitude and Cost of Firefighter Injuries in the U.S." is an upcoming, free webinar that will present the results of work by NFPA and the Fire Protection Research Foundation on the extent, economic cost, and causes of firefighter injuries in the U.S. An economic model will be presented which links injury type with cost. Case studies will illustrate the cost of injury at the local level.

According to the most recent study by NFPA on firefighter injuries, 68,085 firefighter injuries were reported in the United States in 2015. Of these, 29,130 occurred at the fireground. Strain, sprain, muscular pain resulted in more than half of the injuries received during fireground operations (53%) and non-fireground activities (60%). In addition to injuries, there were 8,350 documented exposures to infectious diseases (e.g., hepatitis, meningitis, HIV, other) in 2015. This amounts to one exposure per 2,500 emergency medical service runs by fire departments. There were an estimated 27,250 documented exposures to hazardous conditions (e.g. asbestos, chemicals, fumes, radioactive materials, other) in 2015. This amounts to one exposure per 40 hazardous condition runs by fire departments. In 2015, there were an estimated 16,600 collisions involving fire department emergency vehicles responding to or returning from incidents. This is the highest number of collisions since NFPA began collecting this information in 1990. 

Firefighter injury studies by the NFPA indicate that although other loss indicators of the nation’s fire problem are declining, the rate of firefighter injury per fire incident is not. A deeper understanding of the costs associated with these injuries will illuminate their impact on the nation’s resources dedicated to fire safety and provide benchmarks to evaluate strategies to reduce these numbers in the future.

Reply to this statement if you are capable of being truthful to yourself. I have always followed my electrical safety training. Unfortunately, for majority of us, the honest answer is no, I have not always followed my safety training. For some of us it may have been when working on a 120-volt circuit. For others it may have been a 13.8 kV system. It really doesn’t matter what the voltage, current or incident energy was. Nearly 25% of the electrical contact fatalities occur at or below 220 volts. Most of us work on electrical systems that have the capacity to kill. A fatality has probably been recorded for the type of electrical system you work on. It would be surprising to meet someone who did not know that contact with electricity can be fatal. Yet, according to the Bureau of Labor Statistics, since 2003 there has been an annual average of 186 electrocutions in the workplace.

The first question is why do we put ourselves at risk of becoming a fatality? We have been trained to recognize and avoid electrical hazards but still we put ourselves at risk. We know that our death is a potential outcome of performing the task the way we intend to do the work. We know that the circuit should be deenergized regardless of voltage or incident energy. If energized work is justified, we know we should get the appropriate tools and use the correct personal protective equipment. However, at some point in our career we do not shut off the system or take the trip out to the truck to get the proper gear. The next question is why do we decide to risk our life?

Over my career, the most common answer is that we can’t be bothered: we can’t be bothered to shut the system down; we can’t be bothered to walk downstairs to the panelboard; we can’t be bothered to take the time necessary to correctly don the protective gear; we can’t be bothered to come back tomorrow to finish up the work; we can’t be bothered to take time to explain to our employer that being at risk is wrong; we can’t be bothered to forego accepting a job that puts us at risk, and/or we can’t be bothered to protect ourselves when a task will only take a few moments. 

So, we justify risking our lives to ourselves: the disconnect is too far away; I know what I am doing; they will not let me shut the production line down; the protective gear makes it difficult to work; I have never been injured doing it this way; I shut it off so it must be off; my shift is done in a few minutes; I won’t make a mistake; I’ve been shocked before; it’s only 277 volts, and/or if I don’t do it someone else will. Unfortunately for many of us, we justify putting a paycheck ahead of our life.

Sometime during our career, many of us have put ourselves at risk of becoming a fatality regardless of our safety training. We may have done so with no adverse consequence. In that case no one is the wiser. No harm, no foul? We may have taken a risk and ended up with a temporary injury or some time away from work. Were we rewarded for being a hero who took an undue risk or were we tagged as an employee who violated the rules? Worse yet, some have risked their life and lost. Was the consequence of becoming a fatality and its impact on their family considered when they justified ignoring their safety training?  No one alive can know the answer to that question.

When I host Thanksgiving, it’s a whirlwind. I’ve got multiple dishes to prepare in a very short window of time; I want my house to look welcoming, festive, and clean; and at some point (usually about 45 minutes before my guests arrive) I frantically realize that I still need to take shower and make myself look at least somewhat presentable.


From there, I’ve got to juggle a series of cooking feats to get multiple dishes on the table, all while chatting with guests, digging out a tray for my aunt’s appetizers because she forgot to bring her own, and rummaging through the bathroom cabinet for my sobbing niece who just fell on the driveway and cut her knee. 


And through it all, I need to make sure to keep a close eye on what I’m cooking. So simple!


In theory, keeping focused in the kitchen while cooking really is a simple, straightforward message. But with all the distractions of the holiday, it’s easy to see why there are more than three times as many home cooking fires occur on Thanksgiving Day as on a typical day of the year. In fact, the number of home cooking fires on Thanksgiving spikes by a whopping 238 percent.


These and a wealth of home cooking fire statistics are included in NFPA’s latest U.S. Home Cooking Fires report, which shows that cooking is the leading cause of home fires year-round, accounting for almost half of all US home fires (49 percent) and reported home fire injuries (45 percent). Cooking is the second-leading cause of home fire deaths, accounting for 22 percent of all fire deaths. Unattended cooking is the leading cause of home cooking fires.


All these statistics and risk factors beg the question: How can everyone ensure a festive, fire-safe Thanksgiving with the people we care about most?


First and foremost, plan ahead so that staying in the kitchen while you’re cooking is actually doable. Assign family members and guests to tasks like answering the door, fetching band aids, etc., so that you can do the following:


  • Stay in the kitchen while cooking on the stovetop. Some types of cooking, especially those that involve frying or sautéing with oil, need continuous attention.
  • Make use of timers to keep track of cooking times, particularly for foods that require longer cook times.
  • Keep things that can catch fire like oven mitts, wooden utensils, food wrappers, and towels at least three feet away from the cooking area.
  • Avoid long sleeves and hanging fabrics that could come in contact with a heat source.
  • Always cook with a lid beside your pan. If you have a fire, slide the lid over the pan and turn off the burner. Do not remove the cover because the fire could start again. Let the pan cool for a long time. Never throw water or use a fire extinguisher on the fire.
  • For an oven fire, turn off the heat and keep the door closed. Only open the door once you’re confident the fire is completely out, standing to the side as you do. If you have any doubts or concerns, contact the fire department for assistance.
  • When cooking a turkey, make sure to stay at home and check it regularly.
  • Keep children at least three feet away from the stove. Kids should also stay away from hot foods and liquids, as steam or splash from these items could cause severe burns.


With all that in mind, here’s the tip I keep reminding myself as Thanksgiving Day fast approaches: I can only do what I can – and I need do it safely – so that I can ensure a festive holiday for my guests while focusing on what I’m truly thankful for, first and foremost my two boys, who after dealing with me prepare for the day, are surely grateful we’re not hosting any other holidays this season.

Protection of vertical openings is a subject about which we receive a fair number of questions here at NFPA. In general, floors need to provide a smoke-resistant barrier between stories in a building to prevent smoke from migrating vertically and affecting occupants on stories other than the story of fire origin. A vertical opening is a “hole in the floor” that requires some form of protection. Different vertical openings have different names: convenience opening; communicating space; atrium; two-story opening with partial enclosure; and others. The varied protection strategies offered by the code are, I think, what creates some confusion. To determine the protection requirements, refer to Section 8.6 and the X.3.1 subsection of the applicable occupancy chapters. A quick overview of a few scenarios based on the 2018 edition of the code follows:

  • Full enclosure: Where vertical openings (holes in floors) exist, enclose the openings with fire barriers on each story exposed to the opening. The required fire resistance rating of the enclosing barriers depends on the number of stories exposed to the opening(s) and whether it is new or existing. See 8.6.5 for the required rating. Examples include elevator hoistways and utility shafts. This scenario satisfies the base requirement of 8.6.2. Note that exit stair enclosures, which are a form of vertical opening, must meet the more stringent requirements of; meeting the exit enclosure requirements inherently meets the vertical opening requirements.

Where full enclosure on all exposed stories is not practical or is undesirable, the code offers several alternatives. These are referred to as continuity exemptions in 8.6.3; here are examples of a few of them:

  • Partial enclosure: Where a vertical opening occurs in one floor only (i.e., only two stories are exposed to the opening), 8.6.8 permits the opening to be enclosed on one story or the other leaving one of the stories exposed to the opening. The required rating of the enclosing barriers is covered by 8.6.5 (1-hr for new, ½-hr for existing). No special occupancy chapter permission is required and there are no restrictions on what the opening can be used for. If the opening is used for a stair, the stair could be used as part of a required exit access, but it does not qualfiy as an exit since and require exit stairs to enclosed on every story (there is an exemption for some existing two-story exit stairs in
  • Convenience opening: Where a vertical opening occurs in one floor only (i.e., two stories are exposed to the opening), the opening might be permitted to be unenclosed on both stories if it meets the requirements of These unenclosed openings require permission in the X.3.1 subsection of the applicable occupancy chapters, where X is the chapter number (e.g., 38.3.1 for new business occupancies. Some of the key requirements of include: the opening can’t communicate with openings to other stories; new openings must be separated from any corridors (these convenience openings are sometimes found in office building tenant spaces); if the opening is used for a stair, the stair does not get any credit as a means of egress.
  • Communicating space: These are sometimes referred to as “mini-atriums.” Unlike a convenience opening, a communicating space can expose up to three stories to each other. With the increased exposure comes additional requirements and limitations in 8.6.6. Communicating spaces are permitted unless prohibited by the X.3.1 subsection of the applicable occupancy chapters; for an example, see, which prohibits communicating spaces in new health care occupancies. Portions of stories that are exposed to the communicating space must be separated from the remainder of the building by fire or smoke barriers depending on whether the building is protected by automatic sprinklers. Areas outside the communicating space need access to an exit without passing through the communicating space, and the communicating space needs to be open and unobstructed so a fire on any story within the communicating space will be readily apparent. Contents within the communicating spaces are restricted to low hazard (essentially noncombustible) unless the space has automatic sprinklers. By meeting all the criteria in 8.6.6, the unenclosed floor are openings are protected.
  • Atrium: Whereas a communicating space is limited to exposing not more than three contiguous stories, an atrium can expose any number of stories because it is subject to the stringent requirements of 8.6.7, which include automatic sprinkler protection throughout the building. New atriums must be provided with an engineering analysis to show that smoke from a fire in the atrium will not prevent the use of the highest exit access path exposed to the atrium for the time needed to evacuate; this frequently necessitates an engineered smoke control system. Think of a Hyatt or Embassy Suites hotel in which, upon leaving your guest room, you’re immediately in the atrium space. This exit access path needs to be maintained relatively smoke free to allow occupants to reach the enclosed exit stairs. The design of atrium buildings is largely performance-based and frequently involves computer fire and egress modeling.

The code offers a handful of additional vertical opening protection strategies – see Section 8.6 for the details. Be aware that some of the Life Safety Code vertical opening protection requirements might differ from those in the International Building Code; in some cases, the Life Safety Code might be more restrictive (several attendees at classes I’ve instructed have indicated this is the case for two-story, unenclosed vertical openings). Where a jurisdiction has adopted both NFPA 101 and the IBC, designers will likely need to comply with the more restrictive provisions so as to meet the requirements of both.

Thanks for reading, and stay safe.

  • 310.3(A) - Revised to include a voltage rating threshold up to 2000 volts to correlate with the relocation of medium voltage requirements to new Article 311
  • 210.8 - Revision to clarify how proximate measurement for GFCI protection is made
  • Table 220.12 – Revisions to the general lighting load table
  • 250.25 - New section covers requirements for grounding and bonding of supply-side disconnects
  • 314.27 (C) - Revision requires outlet boxes mounted in ceilings of habitable rooms in dwelling units to be provided with a box listed for ceiling fan support where a ceiling fan may be installed

But remember, the majority of questions and requests for information will come from all of you. So I invite you to join us to learn more about the changes that affect the way you use the code every day. Don’t miss out! Check out our webpage for the details and register today. I look forward to hearing from you!


The ongoing push toward sustainability of refrigeration systems requires the adoption of low global warming potential (GWP) refrigerants to meet the shift in environmental regulations. In 2016, nearly 200 countries signed the Kigali Agreement, a legally binding accord focused on the reduction of hydrofluorocarbons (HFCs) - the hydrogen, carbon, fluorine based compound that is commonly used in refrigerators and air conditioners. The new class of replacement refrigerants pose various hazards including increased flammability risks.

As new refrigerants are phased in, there are new hazards that emergency responders need to be aware of in order to adjust response tactics. It is essential that emergency response and preparedness is emphasized during the transitional process and that firefighters and others are familiar with the change in material hazards and appropriate response procedures.

The Fire Protection Research Foundation (Research Foundation), the research arm of NFPA, collaborated with NFPA on a two-year research project on flammable refrigerants. Funded by an Assistance to Firefighter Grant from FEMA, the goal of the project was to enhance firefighter safety and reduce potential injury by providing training on the hazards that may exist in appliances with flammable refrigerants. More specifically, the objective was to document key information about the technology and potential hazards so that information could be shared via interactive training modules that include classroom sessions, online learning, and educational videos for the fire service.

As part of this research initiative, the Research Foundation facilitated a workshop in September 2018 with industry stakeholders and members of the fire service. The risks that firefighters will be exposed to during a call involving flammable refrigerants were discussed, and brainstorming about the content and materials needed to inform audiences took place. One clear takeaway was that although firefighting is an inherently dangerous profession, emergency responders need to be trained and educated on the shift in refrigerant materials in order to appropriately adjust tactics and keep safe. Participants also expressed concerns about the products of combustion, and recommended that possible symptoms for exposure during and after an incident be clarified; and that the adequacy of PPE and post-event de-contamination strategies be addressed. Workshop proceedings can be found here.


In May of this year, The Research Foundation published another report documenting the hazards associated with flammable refrigerant technologies. That document contains the results of a literature review, consisting of flammable refrigerants baseline information, existing product usage details, new implementation considerations, potential integration into future technologies, and current response and tactics guidance. Additionally, researchers looked at the current and potential use cases for refrigerants, the various applications in which they are employed, the types of environments in which they might be encountered, and a range of associated threats. These hazards must be balanced against their performance for specific applications, including toxic thermal decomposition, combustion products, increased flammability, explosion risks, and pressure release scenarios.

The report also identified a few existing knowledge gaps, specifically that fire service personnel are not well-versed on the evolving hazards associated with new flammable refrigerants. Although the potential production of hydrogen fluoride and other toxic thermal degradation byproducts exists for all halocarbon refrigerants, further investigation is needed to determine the difference in the toxic quantities produced by existing refrigerants versus the new refrigerants. To date, the variations in hazards have not been completely defined - most likely because the standards governing refrigerant charges are still under review. The gap analysis was intended to inform new NFPA training for the fire service which will debut later this year to assist first responders in recognition, evaluation, and mitigation of any flammable refrigerant related hazards. As part of this research, demonstrative tests were also conducted to support the development of these training materials.

The transition to this new class of refrigerants is already underway and being led by the countries that signed on to the Kigali Agreement. Thus, it is critical that firefighters and others are aware of the potential fire hazards that may occur in various applications such as retail food refrigeration units or air conditioning systems.
