Book Description
This volume describes fire behavior and fire protection of timbers in outdoors and indoors application mainly in construction industry. The Authors’ novel approach considers the relationship between various species and age of timbers and its fire behavior at different thermal and fire loads. Quantitative data of ignition speed and flame propagation as well as generation of heat, smoke and toxic products are discussed. Analysis of fire resistance of various types of building materials based on timber of different species as well as the novel data on the effect of natural and accelerated aging of timbers on its fire behavior are discussed. The main practical methods of fire protection of new and ancient timber buildings and structures to increase its fire resistance are considered. The book should be useful for a wide range of readers: chemists, physicists, material scientists, architects, engineers, constructors and restorers.

Book Description
Fire resistance of timber structures is a very large field. In order to keep this document relatively small, the scope of is limited as follows: This report attempts to define a Performance-Based framework for the fire safety design of multi-story timber buildings. The report concentrates on medium-rise multi-story timber buildings from 3 stories to 10 stories tall, which are likely to be most popular and technical feasible. Taller buildings are discussed briefly. The report concentrates on mass timber buildings, constructed from large timber posts and beams (from LVL or glulam) and large wood panel construction using cross-laminated timber (CLT) or other heavy timber panels. Light wood frame buildings protected with gypsum plasterboard (2 by 4 construction) have been covered elsewhere and are not considered to be feasible for building above about 6 stories. The report concentrates on the fire resistance of structural elements and assemblies, and does not include early fire safety issues such as ignition and flame-spread on wood surfaces. It does not address broader fire safety issues such as fire safety systems, fire fighting, or evacuation. External fire spread via building facades and windows is partly included, since wooden fa ade claddings are considered by many architects to be an essential feature of timber buildings, at least up to 8-10 stories. Automatic fire sprinkler systems are discussed briefly, since the combination of active and passive fire protection is considered to be an important way to provide fire safety for tall timber buildings. Fire resistance of timber connections is included briefly, including both mechanical fasteners and glued connections. The influence of adhesives on the fire behaviour of bonded structural timber elements is discussed briefly.

Book Description
On March 22, 2018, two male career fire fighters, ages 50 and 29, died following a structure collapse while working to extinguish hot spots following a structure fire in a 140-year old mill building. The previous day, March 21, 2018, the local career fire department was dispatched at 1616 hours, for a report of a structure fire with possible entrapment. The deputy chief arrived on scene and observed heavy smoke at the site of a large Type IV (heavy timber) construction mill building under renovation to create an apartment complex. He radioed dispatch and upgraded the incident to a working fire assignment and assumed incident command. Arriving crews were assigned to an offensive interior attack with 1 3/4-inch hand lines deployed through a door at Side Alpha. A fire fighter from Engine 99-5 was injured when he fell during interior search operations for a reported missing fire fighter. The Incident Commander ordered an evacuation of the structure and requested a personal accountability report after the fire rapidly spread throughout the 53,000-square foot structure. The reported missing fire fighter was accounted for and defensive operations were initiated with elevated master streams and ground monitors on all four sides of the structure. Approximately two hours into the incident, cracks began to form in the Side Bravo exterior wall and a large portion of the structure collapsed (Sides Bravo, Charlie and Delta) just minutes after Truck 89-1 was repositioned out of the collapse zone. Fire fighters from five fire departments worked overnight to extinguish the fire. The next morning, on March 22, 2018, Fire Department officials discussed the situation with the building owner and an engineer contracted by the building owner. The Incident Commander, the city building official, the owner, and the engineer entered the structure from Side Alpha to visually inspect floors one and two. Then they used an elevated aerial platform to visually inspect the roof and top two floors for structural stability. Following the inspection, fire department officials made the decision to use the elevated aerial platform for access to send a hose line crew onto the third and fourth floors to extinguish the remaining hot spots. Truck 99-1 was repositioned at the Side Alpha / Delta corner so that fire fighters, supervised by the Incident Commander (located in the elevated platform), could access the fourth floor. At approximately 1515 hours, a collapse occurred that dropped three fire fighters and the shift commander (assistant chief) to the ground. The Incident Commander, located in the bucket of Truck 99-1 immediately radioed a Mayday and requested additional resources. Fire fighters worked for 29 minutes to free the four fire fighters trapped under the debris. Two fire fighters received fatal injuries in the collapse while the assistant chief and the fourth fire fighter were seriously injured.

Book Description
"This report examines British Columbia (BC) residential building fires as a function of the general construction type. The fires that are examined were reported to the BC Office of the Fire Commissioner (OFC) between October 20 2008 and October 19 2013. The data included in this analysis was provided by 339 reporting agencies across the province, sampled from first nations band areas, non-municipal areas (with and without fire protection), and municipal areas. There were a total of 34,708 fire incidents reported during this period, of which only 11,875 were building fires attributable to a particular type of construction. Comparisons were drawn between the 11,875 fires that occurred in the five broad general construction type categories: (1) combustible construction - exposed wood joists / wood trusses (also called "combustible construction" throughout this report, n = 2,241), (2) protected combustible construction - wood joists / wood trusses protected by plaster/gyproc (also called "protected combustible construction" throughout this report, n = 7,808), (3) heavy timber construction (n = 226), (4) non-combustible construction - exposed steel joists / steel trusses (n = 507), and (5) protected non-combustible construction - protected steel or concrete (also called "protected non-combustible construction" throughout this report, n = 1,093). Across all these fires there were a total of 772 injuries and 107 deaths reported to the OFC"--Overview of this Research.
