How to Control Risk [5 Techniques]


With the record breaking and devastating wildfires in California, private fire protection services are becoming more visible. These services are offered by insurers, such as AIG and Chubb, to add an extra layer of protection to their high value insured properties. Much of the media seeks to vilify the “rich” for engaging in this practice. However, as any of us would, we merely use the tools at our disposal to reduce our exposure to loss.

BusinessDictionary.com defines risk as, “A probability or threat of damage, injury, liability, loss, or any other negative occurrence that is caused by external or internal vulnerabilities, and that may be avoided through preemptive action." This definition, as it applies to the insurance industry reads, “A situation where the probability of a variable (such as burning down of a building) is known but when a mode of occurrence or the actual value of the occurrence (whether the fire will occur at a particular property) is not.”

The most succinct definition of risk comes from NFPA 1250, “a measure of the probability and severity of adverse effects that result from an exposure to a hazard”.  NFPA 1250, Recommended Practice in Fire and Emergency Service Organization Risk Management, provides this definition of risk, and outlines risk managements plans and processes that should be implemented by fire departments.  Understanding that risk is an inherent part in our daily duties, there are five techniques that can be employed to manage or control this risk.
  1. Exposure Avoidance
  2. Loss Prevention
  3. Loss Reduction
  4. Segregation of Exposures
  5. Contractual Transfer
Exposure Avoidance. This is risk control by simply opting out, and steering completely clear, of a particularly high hazard activity, event, or location.

Loss Prevention. This is the use of methods and measures to reduce the probability of a loss from occurring.  These can include inspections, audits, or training programs.

Loss Reduction. Theses are measures used to reduce severity of loss, even if engaging in a high risk activity. A good example would be the use of PPE when entering a structure fire. This would also include post-accident/loss activities, procedures, and processes.

Segregation of Exposures. This could also be a loss reduction tactic. This is accomplished by breaking large units into smaller ones, and distributing equipment and resources, throughout a large area. This reduces the likelihood of a total loss if all items, personnel, resources were to be located in a single area.

Contractual Transfer. This is the use of a formal insurance policy. This is affected by the transfer of responsibility from one entity to another.

These five methods of risk management are defined and outlined in NFPA 1250.  The insurance industry, however, would add one additional method to the list - retention.

Retention. This is when an organization acknowledges that there is a risk, and prepares for the loss (financially and physically) themselves. They are self-insured, which simply means that they control all the money, instead of an outside or third-party “insurance company”.

Power Lines and the WUI

Photo from: LA Times
As fires continue to rage throughout California, investigations into the twelve fires that occurred earlier this year, and burned 245,000 acres, have been concluded. Investigators with Cal Fire have determined that these fires were caused by Pacific Gas & Electric Company power lines. High winds in the area caused trees and branches to fall onto the lines, and in at least one case a power pole failed and collapsed. PG&E currently has a vegetation control program in place with a budget of $400 million per year.

NFPA 1, Fire Code provides clear guidance on how to prevent fires from electrical lines. Chapter 17, Wildland Urban Interface outlines the following  requirements for vegetation clearance around electrical transmission and distribution lines, conductors, and their appurtenances.

  • 10 feet clearance is required around all poles or towers
  • At the time of trimming, the following minimum clearances should be provided based on the line voltage:

  • As the growth returns, it is permitted to grow to within the clearances shown in the table below. Once this minimum distance is reached vegetation must be trimmed back to the required minimum clearance.
                             
  • The AHJ has authority to adjust clearance requirements based on local needs or conditions, and vegetation type

NEC Hazardous Locations


Though many jurisdictions have electrical inspectors that enforce the provisions of NFPA 70, National Electrical Code (NEC), there are provisions and requirements that overlap with the duties of the fire inspector. Some of these areas or occupancies include high hazard industrial facilities, paint rooms and spray booths, hazardous materials storage, and fuel handling processes and operations. These areas require that the fire inspector properly classifies the hazardous location in order to ensure proper installation of electrical wiring and components.


NFPA 70, Article 500 defines these hazardous classifications as follows, “Locations shall be classified depending on the properties of the flammable gas, flammable liquid–produced vapor, combustible liquid–produced vapors, combustible dusts, or fibers/flyings that could be present, and the likelihood that a flammable or combustible concentration or quantity is present. Each room, section, or area shall be considered individually in determining its classification.”  These are divided into classes and divisions.


Class I - locations in which flammable gases, or flammable or combustible liquid-produced vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures.


Class II - locations that are hazardous because of the presence of combustible dust.


Class III - locations that are hazardous because of the presence of easily ignited fibers, or where combustible flyings are handled, manufactured, or used.


The charts below show the Class and Divisions categories.






*Group E. Atmospheres containing combustible metal dusts, including aluminum, magnesium, and their commercial alloys, or other combustible dusts whose particle size, abrasiveness, and conductivity present similar hazards in the use of electrical equipment.




In some instances a “zone” designation may be used as an alternative to the division classification system shown here. These zones will either be Zone 0, Zone 1, Zone 2, or Zone 20, Zone 21, Zone 22. These are defined in NFPA 70, Article 505 and Article 506.


Article 505 defines Class 1, Zone 0, Zone 1, and Zone 2 as “locations where fire or explosion hazards may exist due to flammable gases, vapors, or liquids.” Article 506 defines Zone 20, Zone 21, and Zone 22 as “locations where fire and explosion hazards may exist due to combustible dusts or ignitable fibers/flyings.”


As a tool for the field inspector or plans examiner we have created a single page reference that provides quick access to the classification and division definitions.

Kent's 9 Rules of Analysis [for Fire Protection Professionals]


In the 1940's, Sherman Kent, a Yale professor and father of American analytical intelligence, authored a book entitled, Strategic Intelligence for American World Policy. In his book, written for intelligence analysts, Kent outlines nine rules of analysis. Though written for the intelligence community, these nine rules of analysis can be applied to what fire protection professionals do everyday.

As fire protection professionals we are constantly faced with a barrage of data and information.  This data and information must be analyzed and evaluated to specify and approve life safety features, design fire protection systems, promote and develop prevention programs, and more. How can we ensure that the right information is being analyzed and the best options are being presented? To be great at the art and craft of analyzing and presenting information, we should learn and apply Kent's nine rules of analysis.

9 Rules of Analysis


1. Focus on Policymaker Concerns. Who are the policymakers in your community? What is their primary concern? The "policymaker" can be the client, the commissioners, or other group or individual that will be making the final approval decision and releasing needed funds. Issues and requests will be better received if presented in a manner and time-frame that suits the affected policymaker.  
"Accommodate clients by producing assessments timed to their decision cycle and focused on their learning curve".

2. Avoidance of a Personal Policy Agenda. What is best for the policymaker (client,group, community)? This may directly conflict with the needs of the individual, the department, or the company. 
"Identify and evaluate alternatives...allow the client to recommend and choose."

3. Intellectual Rigor. Information and solutions should be "rigorously evaluated for validity".  
"Judgments are based on evaluated and organized data, substantive expertise, and sound, open-minded postulation of assumptions."

4. Conscious Effort to Avoid Analytic Biases. Review the data, information, and problem with an open mind. Don't get tunnel vision that tries to fit the problem into your 
"Resist the tendency to see what they expect to see in the 

5. Willingness to Consider Other Judgments. Argument and dissent should be encouraged, as long as, the dissenter's judgement is made clear and based on alternative assumptions or different interpretations of information. A good example of this is the model code development process. A group of individuals that gather, share their "judgments", to create the most useful and relevant code or standard. 


6. Systematic Use of Outside Experts. The more we know about new technology, new processes, new structure or building methods, the better we can serve those "policymakers" and our communities. This can be largely accomplished by building the right relationships with experts in other fields, that can provide and interpret the new information. 
"Take account of a wide range of outside opinions...cultivate working relations with outsiders..."

7. Collective Responsibility for Judgment. Collective responsibility is the idea that individuals who are part of of a group (the "collective") are responsible for the groups actions and occurrences by tolerating, ignoring, or harboring them, without being actively engaged in the decision. Being aware of this, fire protection professionals should always speak up, represent, and defend their analysis, to their clients best interest.
"Allow time for coordination and accommodate collective responsibility."

8. Effective Communication of Policy-Support Information and Judgments. A good method to use is The Pyramid Principle developed by Barabara Minto. This is a method of corporate communication that starts with the solution then presents recommendations, and supporting ideas.
"Shorter is usually better, with key points stated quickly... If the tradeoff is between adding length and allowing brevity to cause confusion, provide a carefully measured dose of detail."

9. Candid Admission of Mistakes. If you have made a mistake readily admit it and present solutions for corrections. Master your subject and trade-craft, study mistakes, learn by conducting a critical review of failures.
 "Admission and explanation of analytic errors are likely to increase credibility with policy clients."

These decades-old postulates can serve as a refreshing blueprint for the development, presentation, and analysis of information and solutions to problems. Define the "policymakers" primary concern. Seek intellectual rigor, and strive to never bring personal agenda or bias to the task. Seek advice and test other’s hypotheses. Take responsibility and credit as a group. Hold yourself to the highest standards of professionalism and excellence in your field.  Admit mistakes and be quick to respond to, and correct, them.

Fire Inspector Qualifications - A Path for Professional Development

Photo credit: Los Angeles Fire Department
It has been almost thirteen years since I walked into the fire academy to get the education I needed for a career. My intention was to become a “firefighter” however, it was in the academy, that I learned of the various pathways that title and role could follow. Of the nearly 400 hours of training that is required to become a certified firefighter in the state of Florida, about four of those hours are dedicated to fire prevention. It was with this brief introduction that I knew the path my career would follow.


A quick search on professional development in the fire service will return a plethora of information on career guidance and advancement. The majority of this information will be based on the operations and suppression side of the industry.  There is a disproportionately small amount of information on career development for the fire prevention, inspections, and plan review divisions of this field.


With the many different certification bodies, educational programs, and course options, it can be difficult to create a clear path for success in the field.  However, with some simple guidance and a bit of persistence success can be had. The starting point is within yourself. You must determine the goals and objectives that you have for your career. Do you want to work for a municipal fire department or an industrial type of department? Do you want to work in public service, or the private sector? Are you excited about a career in your “hometown” department, or are you looking forward to the travel and “adventure” that overseas contract work can provide? What part of fire prevention do you want to focus on - inspections, plan review, public education, or investigations? Where are you now and where do you want to be, and what is the ultimate goal of your career? Do you desire to move up the career ladder - inspector, supervisor, chief? The answers to these questions will help to shed light on your career pathway.


After you have an idea of what direction you want your fire inspection and plan review career to follow, you will need to obtain the necessary certifications.  Typically, you will find that these requirements follow these four primary certification paths. These are State specific requirements, IFSAC/ProBoard, International Code Council (ICC), and National Fire Protection Association (NFPA).

Always start with your state’s requirements. Some states defer the certification process to these other listed certifying bodies, and others have their own programs for certification.  Beyond the state requirements, the chart below, shows the certification levels that are available, in the order they should be obtained within.



For certifications related to advancement, there are many options. There is currently no set standard for obtaining the top rank within fire prevention (such as Fire Marshal or Chief of Prevention). The state of Florida and the state of California are two states that provide a formal certification for these positions. Their programs can serve as a model for other states, departments, and organizations to follow.


Model Programs

Florida

California

The chart below is based on the Department of Defense (DoD) requirements for fire service positions. This can serve as a general guide to professional development and advancement. In the least, this provides a framework to build your career on, it can be modified to meet your particular state or departments requirements.





Keep in mind that the career path presented here is showing only the path of fire inspector and plans examiner, to Chief Officer.  There are additional certification requirements for those who desire to take the fire prevention path of public educator, fire investigator, or community risk reduction specialist. Though there is overlap in the certification process, each of these have their own path to the top positions in this field.

Benefits of Fire Door Commissioning

This guest post is provided by our #FireDoorSafetyWeek partner, Aegis Fire Barrier Consultants, and is written by, Justin B. Biller, P.E., CHFM, CLSS-HC, CFPS | AEGIS Technical Director.



Doors are a major concern for building owners and facility managers. Ongoing maintenance of doors and architectural hardware represents a significant cost margin to building owners. Nowhere, is this more true than for healthcare facility and engineering managers where building footprints are vast - often in excess of 1 million square feet or more. Maintaining all doors in large facilities is always a challenge, but of even higher concern for healthcare engineers is fire and smoke barrier management, wherein door maintenance is a critical component. This point is not lost on a highly accomplished architect, Amanda Adams AIA, who has spent much of her career in significant restoration projects – she has noted first- hand how important fire and smoke door assemblies become in sustaining code compliance, providing a safe and healthy environment for building occupants, and in achieving her overall architectural vision for a space. Ms. Adams highlighted this point to us at AEGIS, wherein she states,


“the foremost requirement of architecture is shelter. This ranks above aesthetics and creative efforts. All building occupants - users, visitors, tenants, residents - expect a building to provide shelter from the elements. At times, emergency situations arise that cause a building to offer shelter or protection from internal threats (often this is a fire threat)....whether that be protect in place or provide a safe exiting scenario. Passive life safety systems hold top priority in life safety; active systems increase safety and provide additional time. Properly functioning fire doors are a critical basic component to the passive system. A door must fit properly in its frame. Closing hardware must work properly. Positive latching hardware completes the barrier.”

The added strain on fiscal responsibilities for healthcare facilities to “do more with less” heightens the need to challenge installers to do the work right the first time – it is often noted on annual inspections of fire and smoke door assemblies that the ongoing challenges to maintenance stem from improper installation (i.e., improperly plumbed door frame and jamb, incorrect or insufficient hardware, incorrect door or glazing type, etc.).
According to the Door Security and Safety Foundation, although doors only represent 2% of a typical construction budget, on average more than 30% of punch-list items are door-related. It is, therefore, the opinion of many within the industry that it is in the best interest of building owners to verify fire and smoke doors are installed properly from the outset – a determination that committee members of NFPA 80, Standard for Fire Doors and Other Opening Protectives also found imperative. In its most current published editions (2016 and 2019), NFPA 80 prescribes in section 5.2.1 that “upon completion of the installation” these assemblies are to be inspected and tested.
Here at AEGIS we believe as well that a comprehensive survey of door installation during construction benefits the building designer and can dramatically decrease ongoing maintenance costs associated with fire and smoke door assemblies. We are here to help you implement this on your next project and can work with your design team through specification and installation through final punch-out.
What is Fire System Commissioning (FCx)
NFPA 3, Recommended Practice for Commissioning of Fire Protection and Life Safety Systems delineates that the commissioning and integrated testing process would include both, active and passive components of fire protection systems. Commissioning is a procedure of verifying a quality process from design inception through development and construction and extends through the life of the building by ongoing maintenance and operations. Passive fire protection systems, including fire and smoke rated door assemblies, serve as a primary component for most building life safety systems with varying degrees of complexity (based on factors such as occupancy and building geometry). Fire and smoke rated doors are often integrated with fire and life safety systems such as fire alarm, sprinkler, smoke control, and emergency electrical systems, thus it becomes imperative for the fire commissioning team (FCxT) to include qualified fire door commissioning agents (Cx) to be employed. Along with NFPA 3, NFPA also developed NFPA 4, Standard for the Integrated Fire Protection and Life Safety System Testing to work in concert with the recommended practices of commissioning, outlined in NFPA 3, to accomplish this task.
AEGIS with its partnerships with engineers and architects, has the practical experience and expertise to support your commissioning team with passive fire protection system components.

Smoke Gasketing and Edge Sealing in Healthcare Occupancies


This guest post is provided by our #FireDoorSafetyWeek partner, Aegis Fire Barrier Consultants, and is written by, Justin B. Biller, P.E., CHFM, CLSS-HC, CFPS | AEGIS Technical Director.



Do corridor doors require smoke gasketing in healthcare occupancies (which are classified as Group I-2 under the International Building Code® (IBC)?


There is often confusion encircling this question with facility managers, designers, and even fire door inspectors. Gasketing is often perceived as an ambiguity in the codes. This fire door component is routinely missed during design and construction, and often leads to further confusion during the life cycle of the building. The question is multi-faceted as there is various criterion to consider.

This is the final installment of a three part series that addresses the more common questions that we have noted in our work with fire and smoke door code compliance. Parts 1 and 2 of the series can be accessed from the Aegis Fire Barrier blog page.

Part 1. When is edge sealing specifically required for fire protection rated doors?
Part 2. Do fire and smoke rated doors require smoke gasketing in healthcare occupancies which are classified as Group I-2 under the International Building Code® (IBC)?
Part 3. Do corridor doors require smoke gasketing in healthcare occupancies (which are classified as Group I-2 under the International Building Code® (IBC)?

For a general listing classification of protection methods, reference to UL is helpful in understanding the parameters of installation regarding Gasketing and Edge-sealing Materials for Fire Doors, Positive-pressure Tested, GVYI.

To address the question – do corridor doors require smoke gasketing in healthcare occupancies (which are classified as Group I-2 under the International Building Code® (IBC), in general the following code excerpts from the model codes are included below.

Corridor Doors - NFPA 101, Life Safety Code, 2012
“18.3.6.2* Construction of Corridor Walls. 18.3.6.2.1 Corridor walls shall be permitted to terminate at the ceiling where the ceiling is constructed to limit the transfer of smoke. 18.3.6.2.2 No fire resistance rating shall be required for corridor walls. 18.3.6.2.3* Corridor walls shall form a barrier to limit the transfer of smoke.”

“18.3.6.3* Corridor Doors. 18.3.6.3.1* Doors protecting corridor openings shall be constructed to resist the passage of smoke, and the following also shall apply: (1) Compliance with NFPA 80, Standard for Fire Doors and Other Opening Protectives, shall not be required. (2) A clearance between the bottom of the door and the floor covering not exceeding 1 in. (25 mm) shall be permitted for corridor doors. (3) Doors to toilet rooms, bathrooms, shower rooms, sink closets, and similar auxiliary spaces that do not contain flammable or combustible material shall not be required to be constructed to resist the passage of smoke.”

As regards the application of NFPA 101 requirements for corridor walls and doors, it is important to recognize the distinction that this code makes from IBC, wherein it does not require corridor walls to be smoke partitions – note the explanatory annex language below specific to this issue:

“A.18.3.6.2.3 While a corridor wall is required to form a barrier to limit the transfer of smoke, such a barrier is not required to be either a smoke barrier or a smoke partition — two terms for which specific Code definitions and requirements apply.”

It is also important to note specifically, that NFPA 101 indicates that gasketing is NOT REQUIRED for corridor doors – note this explanatory language below:
“A.18.3.6.3.1 Gasketing of doors should not be necessary to achieve resistance to the passage of smoke if the door is relatively tight-fitting.”

Corridor Doors – International Building Code, 2012
“407.3 Corridor wall construction. Corridor walls shall be constructed as smoke partitions in accordance with Section 710. 407.3.1 Corridor doors. Corridor doors, other than those in a wall required to be rated by Section 509.4 or for the enclosure of a vertical opening or an exit, shall not have a required fire protection rating and shall not be required to be equipped with self-closing or automatic-closing devices, but shall provide an effective barrier to limit the transfer of smoke and shall be equipped with positive latching. Roller latches are not permitted. Other doors shall conform to Section 716.5.”

“710.5.2.2 Smoke and draft control doors. Where required elsewhere in the code, doors in smoke partitions shall meet the requirements for a smoke and draft control door assembly tested in accordance with UL 1784. The air leakage rate of the door assembly shall not exceed 3.0 cubic feet per minute per square foot (0.015424 m3/(s • m2)) of door opening at 0.10 inch (24.9 Pa) of water for both the ambient temperature test and the elevated temperature exposure test. Installation of smoke doors shall be in accordance with NFPA 105.”

Conclusion
The IBC again is more stringent in its application than NFPA 101 is for this requirement – note the ICC commentary for this section which clearly identifies corridor doors are to meet UL 1784:
“Only doors in smoke partitions that are required elsewhere in the code to be smoke and draft control doors must comply with section. Section 407.3.1 requires corridor doors in Group I-2 to ‘limit the transfer of smoke’; therefore, those doors must meet this section.”
As such, IBC does require corridor doors in I-2 occupancies to meet UL 1784. This results in the effect that life safety surveys involving the use of NFPA 101, 2012 cannot technically mandate the installation of smoke gasketing either for existing or new construction involving corridor doors.
The same would not hold true for fire prevention inspections conducted under the International Fire Code® for facilities constructed to meet either the IBC or the legacy Uniform Building Code (UBC) – previously adopted throughout Western Pacific regions of the US. What strategy should facility managers take about existing fire doors where edge sealing is not equipped on fire doors in their facility? Like so many things in code compliance, the answer depends on the specifics of your individual facility. If you need any assistance in understanding this parameter for your facility, AEGIS has fire protection specialists here to help you with code consulting services and inspection services that can help maintain compliance with fire door strategies.
