What are the principal fire safety features of a completed EMTC building?
How do the principal fire safety features compare with steel and concrete buildings of a similar height and area?
Though the primary structural materials are different, 7 to 12-storey EMTC and non-combustible buildings share the same principal fire safety features
What’s the difference between a fire resistance rating and an encapsulation rating?
A fire resistance rating (FRR) represents the time that an assembly of materials will withstand the passage of flame or transmission of heat. A material assembly includes the main material (e.g., mass timber) and the encapsulation material if present.
An encapsulation rating represents the time that a material will delay ignition and combustion of an encapsulated mass timber element.
What types of materials are used for encapsulation?
Type X gypsum board, gypsum concrete topping or any non-combustible material with an encapsulation rating of no less than 50 minutes can be used for encapsulation.
What is the role of the fire safety plan?
As for all buildings, a fire safety plan will be required for all buildings. The process for enabling tall wood construction will require local authorities ensure that there is an enforced holistic strategy to address exposed mass timber during the course of construction in the fire safety plan. Additional protective measures can be included in the fire plan.
What are the principal fire safety features of an EMTC building that is under construction?
New requirements related to EMTC buildings are noted in the revised 2018 BC Fire Code. These include:
Limitations on Exposed Wood:
