What is the definition of Type V construction?

Type V construction is defined as wood frame construction, which is characterized by the use of wood as the primary structural element. This type of construction utilizes light-frame materials and offers flexibility and cost-effectiveness, making it a common choice for residential buildings and smaller commercial properties.

In Type V construction, the walls, floors, and roof systems are typically made from wood, which can combust and provide less fire resistance compared to other construction types. Understanding the features of Type V construction is crucial for firefighters as it influences fire behavior, evacuation strategies, and tactical approaches during incidents. Recognizing the materials used in Type V structures helps responders to predict how fire may spread and what challenges they may face in suppressing it.

The other options represent different construction types or materials. Fire resistive construction (A) refers to Type I or II materials designed to withstand fire exposure. All masonry (C) identifies Type III construction, which uses masonry exterior walls but might include wood frame materials, while masonry and synthetics (D) may apply to specific modern materials but do not define a recognized construction type within the traditional coding framework used in fire service classifications.
