This chapter discusses fire service considerations relevant to timber buildings. Firefighting practices may be different in timber buildings compared with non-combustible construction. Internationally, fire services have raised concerns regarding the increased use of wood within buildings and specifically the use of timber structural elements of tall buildings. These concerns often stem from a lack of knowledge of timber performance in fire, and firefighter experience from fires in non-combustible steel and concrete construction and traditional low-rise timber buildings. This chapter discusses relevant concerns of firefighters regarding large and tall timber buildings.
