Introduction to ASTM E 119


The IBC, IFC, and NFPA require minimum fire-resistance ratings for various building materials, components, and assemblies. These fire-resistance ratings are based on the data and testing provided by ASTM, according to the procedures outlined in ASTM E 119. These codes point the user, by reference, to ASTM E 119,  Typically this reference is preceded by terminology such as, “...tested in accordance with”.


ASTM E 119 is the guiding document for the Standard Test Methods for Fire Tests of Building Construction and Materials. This document provides the fire-test-response criteria and procedures for structural materials used in building construction. The application of the test procedures contained in ASTM E 119 is to “evaluate the duration for which” building construction materials and assemblies can either contain a fire, retain structural integrity or both. The types of assemblies to be tested include, bearing walls and partitions, columns, floors and roofs, beams, and protective membranes. Specific requirements must be met for these building products to produce a successful (passing) result. These requirements are referred to as “conditions of acceptance”. The conditions of acceptance outline what makes a successful test. If these conditions are not met, then the material or assembly being tested will fail.


The fire-resistance of building materials is determined and based on the standard time-temperature curve. In this temperature controlled environment, building materials receive their hourly rating. The standard time-temperature curve looks like this:


The temperature is measured by the use of thermocouples strategically placed across the product or material to be tested. Utilizing the time temperature curve the temperature data produced by the thermocouples are read and recorded every five to ten minutes.


Both sides of the material, exposed and unexposed, are to be monitored by thermocouples. Both, the IBC and the NFPA, have requirements for nonsymmetrical building assemblies and components. Nonsymmetrical assemblies are constructed of different components on each side. Based on the order in which the materials are assembled, a fire will burn differently, or at a different rate, depending on which side the fire is on. The test report for these types of assemblies will indicate the fire-resistance rating for both sides. This is important to note, as some code requirements state that the fire-resistance rating should be based on the shortest test duration.


Building construction materials and assemblies can be subjected to two types of tests, the fire endurance test and the hose stream test. Based on the type of assembly being tested (floor, wall, column, etc.) there may be a requirement for a load to be applied. To successfully pass, the assembly or material must support the load throughout the duration of time that it is exposed to fire.  The hose stream test is conducted to measure the “impact, erosion, and cooling effects” of a hose stream on the heated surface of the test material. The test types and duration required will be based on the conditions of acceptance for the material being tested.

"Want to play a game?" [How to Survive an Escape Room]

AP Photo

The energy in the room was suddenly heightened as smoke began to slowly filter through the from some other, outside and unknown, location. How could they escape? The puzzles and riddles didn’t make sense, the clues weren’t coming together, the tumblers weren’t tumbling in the locks.   They were still trapped. With the additional stress of a real (or perceived?) emergency, clear heads became foggy, and chances of escape diminished to nearly zero. As their eyes met, the girls were suddenly and simultaneously gripped by the terror of the realization that this was going to be there permanent grave and final resting place.

The room seemed to be a perfect square or cube, considering the ceiling and floor.  The walls were the drab brown of wood paneling made even darker and dingier by the countless fingers and hand prints from others that had come before. It looked like an old office or library, maybe a study.  A bookshelf along one wall, an antique roll-top secretaries desk on the other. Loosely mounted on the wall to her back was a nearly wall-sized, sepia toned, map of the world. On the floor in the center of the room was a large round rug, probably Persian or Oriental. They didn’t know. The rug was a plush woven pattern of small star-type shapes, sewn within larger star-type shapes. Neatly positioned on the rug, was a brown leather chair. The leather was worn and scratched. A few miniature tears permitted the protrusion of wisps of cotton from the seat, back, and arms. Next to the chair, plugged directly into an outlet on the floor, was a tall slender lamp.  The lamp was a brushed bronze, with a single bulb. The bulb was surrounded by a tassled cloth lampshade. The yellow hues cast by the dark shade, added to the already low visibility within the room. Of all the rooms features and decor, the most ominous was the illuminated wall clock. The clock had been counting down. Now, as smoke filled the room, the clock had stopped at 00:28. Twenty-eight minutes until, what? How did they get here? How did they end up in this locked room? Where was the way out?

This could be the start of another film in the Saw franchise. Or, it could be the beginning of locked-room, pulp fiction mystery of the early 1900’s.  For Julia, Amelia, Gosia, Karolina, and Wiktoria, however, this is no work of fiction, instead, it was the final activity of their young lives. The five girls from Koszalin, a city in northern Poland, were celebrating the birthday at an “escape room” game attraction. What should have been a joyous and momentous occasion, a birthday party for a fifteen year-old, ended in tragedy.

A fire investigation determined that the cause of the fire was a gas leak in the heating system. Local fire authorities also noted the presence of faulty, non-compliant electrical wiring co-mingled with flammable materials. The fire started in the lobby or one of the other rooms of the establishment, and smoke filled into the girls locked escape room. One employee was taken to the hospital in serious condition from direct burns to his body. One report states that the firefighter had significant difficult entering the building to extinguish the fire and recover the girls. This is consistent with statements that the injured employee had tried to get to the escape room but could not due to fire damage.

The girls cause of death was ruled carbon monoxide poisoning. Carbon monoxide (CO) is only one half of the “toxic twins” of smoke.  The other is hydrogen cyanide (HCN). The danger of hydrogen cyanide lies in the fact that it can immediately start to attack and kill the organs, in a fire and smoke scenario this danger is further enhanced by the presence of carbon monoxide. As the HCN attacks the organs, the CO is depriving the oxygen from those same organs. The common materials that are used in the makeup of our homes, businesses, clothing and automobiles - plastics, resins, nylon, polyurethane, melamine, acrylonitrile - produce very high levels of CO and HCN when burning.  These chemicals result in the slow painful death of asphyxiation and bodily organ shut-down.

Originating in Japan, but popularized within just the last few years, escape rooms allow small groups of people to work together using clues, riddles, teamwork, and communication to escape an enclosed space. Typically these rooms are themed, and involve competition with groups in other rooms. The clues are comprised of various combinations of puzzles, props, and riddles.

The thirst for adventure, an adrenaline rush, and an emotion filled social experience has contributed to the growing trend of escape room attractions In the United States.  There is an estimated 2,300 escape room facilities in the US. This is up from only twenty-two in 2014. Bringing in nearly $125,000 a year per room, this is a business that will continue to grow.  How can we prevent the ingredients of escape rooms (and nightmares) - locked in a windowless room, imminent danger, no way of escape - from becoming disaster and tragedy?

One tool we can use is building and fire codes and standards. In the United States there are two primary code-making bodies, the International Code Council (ICC), and the National Fire Protection Association (NFPA). Each of these organizations publish multiple codes and standards including a building code and a fire code.  The ICC publishes the International Building Code (IBC), and the International Fire Code (IFC). The NFPA publishes NFPA 5000, Building Construction and Safety Code; NFPA 1, Fire Code; NFPA 101, Life Safety Code.

Utilization of these codes and standards for building construction, fire protection, or life safety is not mandated or required.  However, all fifty states do voluntarily adopt some version of these, or have created their own codes and standards based on their content.  Once adopted by the state, the provisions then become enforceable as law. Currently neither of these code bodies publishes a code or standard specific to “escape rooms”. They do have sections in their codes for “special amusement buildings”.  This is the section of code that is typically applied to these structures. Escape rooms and special amusements fall into the general building classification of an “assembly occupancy”.

The National Fire Protection Association defines an assembly occupancy as, “an occupancy (1) used for a gathering of 50 or more persons for deliberation, worship, entertainment, eating, drinking, amusement, awaiting transportation, or similar uses; or (2) used as a special amusement building, regardless of occupant load.”

Similarly, the International Code Council defines an assembly occupancy as an occupancy that “includes, among others, the use of a building or structure, or a portion thereof, for the gathering of persons for purposes such as civic, social or religious functions; recreation, food or drink consumption or awaiting transportation…”

A thorough review and application of these codes and standards generates the following mash-up of requirements.

Automatic Fire Sprinkler Systems.
A fire sprinkler system is required for the protection of these structures. Both code bodies allow the omission of fire sprinklers for amusements and attractions that are less than 1,000 sq.ft. and when the travel distance to an exit is less than 50 feet. If the space is less than 10 feet high and 160 feet wide, then sprinklers may also be omitted.

Smoke and Fire Detection.
Smoke alarms and other fire detection devices are required to be installed throughout the amusement space.

Fire Alarm System.
The smoke and fire detection devices are required to send any activation signals to a constantly monitored location.  Additionally, the system must be equipped with an emergency voice/communication system that can be clearly heard throughout the facility. If the fire alarm or fire sprinkler is activated, lighting should be activated so that the exits and exit pathways are clearly illuminated.  Any other sounds or visual application that may be confusing or conflicting are required to be terminated.

Exit Markings.
Exit signage is required to show the location of exit doors and pathways. Directional markings are also required, but they can be setup to be visible only in the event of an alarm or fire sprinkler activation.  Floor proximity exit signage is required and must be mounted with the bottom of the sign between 6” and 18” above the floor. The IBC states that the bottom of the sign must be no more than 8” above the floor. If the exit sign denotes the location of a door, the sign must be within 4” of the door frame.

Interior Finish.
Interior finish includes paints, fabrics, carpets, and other items that are applied to the walls, floors, or ceilings of a structure. These products are classified based on flame spread and smoke development. Class A is the most flame resistant, with a flame spread index of 0-25 and a smoke developed index of 0-450, and is the rating required for special amusement structures.

Another tool that can be utilized for the protection of occupants within escape rooms is to follow industry best practices. The primary best practice is to have a sufficient number of personnel, that are properly trained, to staff the escape room attraction. The staff must be knowledgeable of emergency procedures, fire alarm response, safe exiting and emergency egress procedures, and proper operations of the escape room components and access ways.  Staff should provide instructions on emergency procedures and exit locations to participants prior to the start of the event. Staff should monitoring the rooms via live video feeds. This allows for prompt notification of issues or injuries, and can also be an effective method of communication with participants, if needed.

In construction of the room itself, it is recommended that they have a simple progression and avoid many twists, turns, or small passageways. This contributes to a more quick and direct  exit access in case of emergency. Utilizing only low-voltage electronics for room equipment and props can minimize any potential fire hazard.

It is always a good practice for escape room owners and managers to maintain clear and open communication with the local fire department.  Regular inspections of fire protection and life safety equipment, and the space as a whole, should be encouraged and conducted.

Don’t let the fun, excitement, and faux-adventure of the special amusement of an  “escape room” become a tragedy. Before starting the game ensure that you know where the exits are, you know how to get out of the building, and you know how to notify staff of any issue that may arise.  

John Denley, whose company Escape Room International designs and builds escape rooms across the country, tells owners this, “In order to stay in business, you have to stay up with safety standards, and you have to play by the book. It helps everyone sleep better at night...You want to go into a place with as much safety as possible because you also want to know your investment is safe.”

The man who ran the escape room that killed Julia, Amelia, Gosia, Karolina, and Wiktoria has lost his livelihood and his standing in the community. He is facing up to eight years in prison for “intentionally creating a fire danger and unintentionally causing the deaths.”  At the girls’ funeral, Rev. Wojciech Pawlak eulogized, “In their friendship they were and will remain together. They were together when their lives were ending, they are together here and they will rest together in the cemetery. Forever…”

NFPA, IBC, and ISO Construction Classifications, in Comparison

Building construction classifications are determined based on the buildings structural elements and the fire-resistance rating of those elements.  These elements include, structural framing, exterior and interior bearing walls, and floor and roof construction and their supporting features.

There are three governing “bodies” that provide building construction classifications.  Each group provides a different classification designation, however, they all contain the same construction elements and fire-resistance ratings of materials. These three organizations are:
The National Fire Protection Association defines each construction type and classification in NFPA 220, Standard on Types of Building Construction. The International Building Code defines these construction types and classifications in Chapter 6, Types of Construction. The Insurance Services Office defines these construction types and classification in its Construction Briefs page on its website.

The chart below shows a side-by-side comparison of all three construction type classifications.




Type I and II - Fire Resistive, Noncombustible


NFPA: “...those types in which the fire walls, structural elements, walls, arches, floors, and roofs are of approved noncombustible or limited combustible materials.”

IBC: “...those types of construction in which the building elements...are of noncombustible materials.”

ISO Class 6 (Fire Resistive): “The exterior bearing walls and load-bearing portions of exterior walls must be of noncombustible materials or of masonry, but exterior nonbearing walls and wall panels may be slow burning, combustible, or with no fire-resistance rating.”



ISO Class 5 (Modified Fire Resistive): “...Building construction consists of fire resistive materials such as masonry and protected steel materials not less than 4” thick.”




ISO Class 4 (Masonry Noncombustible): “...Buildings with walls made of masonry, consisting of concrete block, reinforced masonry and can be combined with steel framing..”




ISO Class 3 (Noncombustible): “...Buildings with exterior walls, floors and roofs of noncombustible or slow-burning materials.”




Type III - Ordinary


NFPA: “... that type in which exterior walls and structural elements that are portions of exterior walls are of approved noncombustible or limited-combustible materials...fire walls, interior structural elements, walls, arches, floors, and roofs are entirely or partially of wood…”

IBC: “...that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of any material permitted by this code.”

ISO Class 2 (Joisted Masonry): “...Buildings with exterior walls of masonry or fire-resistive construction rated for not less than one hour and with combustible floors and roofs.”



Type IV - Heavy Timber


NFPA: “...that type in which fire walls, exterior walls, and interior bearing walls and structural elements that are portions of such walls are of approved noncombustible or limited combustible materials...other interior structural elements...shall be of solid or laminated wood without concealed spaces…with the allowable dimensions of [this code]...”

IBC: “...that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of solid or laminated wood without concealed spaces.”

Type V - Wood Frame


NFPA: “...that type in which structural elements, walls, arches, floors, and roofs are entirely or partially of wood…”

IBC: “...that type of construction in which the structural elements, exterior walls and interior walls are of any materials permitted by this code.”

ISO Class 1 (Frame): “...Buildings with exterior walls, floors and roofs of combustible material.”








QA Inspections for Firestopping




The model code organizations, International Code Council (ICC) and National Fire Protection Association (NFPA), each require special inspections for fire firestopping of penentrations and joints. These inspections are required to be conducted to ensure that the proper firestopping system has been utilized and installed properly.

Where is the requirement stated?

NFPA 1, Chapter 12, section 3 states that inspections must be conducted to ensure quality assurance for penetrations and joints.

The International Building Code, Section 1705.16 requires verification and inspection of fire-resistant penetatrations and joints.

When is an inspection required?

NFPA requires inspections of penetrations and joints, “In new buildings three stories or greater in height…” Additionally, fire-resistance rated assemblies in high-rise builidngs are to be visually inspected every 5 years.

The International Building Code, requires these inspections in all high-rise buildings (75’ high and over), and all buildings assigned a Risk Category of III and IV.  Buildings within these risk categories are those structures that “represent a substantial hazard to human life in the event of failure,” or those “designated as essential facilities”.  A complete list of these structures can be found in IBC 1604.5.

What inspection criteria is required?

These inspections will be conducted based on the following ASTM standards:

  • ASTM E2174, Standard Practice for On-site Inspection of Installed Fire Stops
  • ASTM E2393, Standard Practice for On-site Inspection of Installed Fire Resistive Joint Systems and Perimeter Fire Barriers

Firestop Training On-line

The 2012 International Building Code requires special inspection of firestopping for certain structures.  The International Firestop Council has created an in-depth on-line training course for third party firestop inspectors.  The on-line course is free (requires 40-60 hours of time), upon completion of the course a certification test is offered ($250 now, $500 after July 31, 2014).

Link to the program --> http://www.firestop.org/inspection.html

The below article announcing the program was recently released on Fire Engineering.

IFC INTRODUCES CONSTRUCTION INDUSTRYS MOST 
COMPREHENSIVE ONLINE FIRESTOP TRAINING PROGRAM

The construction industry's most comprehensive online firestop inspection training and education program has been developed by the International Firestop Council (IFC) for code officials, inspectors and all building trades professionals associated with commercial building firestopping from design through installation.
The IFC Recommended Training and Education for Third-Party Firestop Inspectors program is a free 40 to 60-hour, firestopping self-study program that educates via recommended outsourced videos, PowerPoint® presentations and documents all available via 22 Internet website links from Underwriters Laboratories (UL), International Code Council(ICC)Federal Emergency Management Agency (FEMA), American Society of Testing and Materials (ASTM), the IFC and other industry-leading sites.  
The IFC created the program, because the industry's one-day classes and other training and education programs were either limited in depth, or not conveniently structured as online programs where applicants learn at a self-study pace on a computer, smartphone or printouts of public domain material.
The program is also important, because the 2012 International Building Code (IBC) requires special inspection of firestopping for buildings over 75-feet-high and for Risk Category III and IV facilities in compliance with ASTM E 2174 and E 2393 standards. The IFC program is the only curriculum currently available that provides third-party inspectors with the high training and competency level required to conduct such inspections. The program's syllabus is available as an interactive webpage or downloadable nine-page document at www.firestop.org/inspection.
While there is no charge for the program's self-study portion, registrants can opt for a two-hour, $250 ($500 after July 31, 2014) IFC-sponsored online, post-training certification test, which requires a minimum passing grade of 80-percent.
The exam's comprehensiveness is illustrated in recent IFC beta test results of several veteran firestop industry experts who did not achieve optimal exam grades. "Even firestop experts would find this test challenging if they don’t go through the self-study curriculum," said test co-author, Pat Tesche, Firestop Inspectors Committee chair of the IFC, which is a Washington-based not-for-profit trade association of manufacturers, distributors, installers and inspectors of passivefire protection materials and systems in North America. "So spending the hours needed to study the entire online curriculum will allow any dedicated student to succeed in the exam, whether they are starting from a low or high level."
Passing students will receive a certificate from the IFC and a free listing at the www.firestop.org website. A free enhanced website listing is also available for students opting for two-hour, hands-on product training from four or more participating firestop manufacturers. "The theory and reading is very effective when combined with hands-on training, and will enable the IFC to offer firestop inspection competence and excellence to the construction industry," said John Valiulis, IFC's Code Action Committee chair.
The program's other features include:
a Study Skills refresher posted by Athabasca University for registrants that haven't taken educational courses recently.
A free pre-exam practice test can be taken online to evaluate full exam readiness.the test consists of 85 questions with multiple choice answers.
The test consists of 85 questions with multiple choice answers.
"Ultimately, well-trained, knowledgeable firestop inspectors will help reduce property loss as well as save lives during a fire," said James P. Stahl Jr., CFPS, president of IFC.
"The construction industry and building officials should accept nothing less than special inspectors who have completed this program."
