Fire Insp & Code Enf Ch 5

_____ - Rating assigned to an opening in a fire wall to indicate the length of time a protective assembly (door, window) can withstand fire conditions. This application may use a lower rating than the surrounding fire-resistant barriers because of the assumption that the fire load will no be close to these assemblies.

• Fire Protection Rating

• Fire-Resistant Materials

• Fire-Retardant Coatings

• Ignition-Resistant Construction

Answer explanation

See page 154

_____ - Wall assemblies that are rated through laboratory testing to determine their ability to withstand fire conditions over a set amount of time.

• Fire-Resistant Materials

• Fire-Protection Rating

• Fire-Retardant Coatings

• Ignition-Resistant Construction

Answer explanation

See page 154

_____ - Applied to the surface of combustible materials to suppress, reduce, or delay the flame-spread rating of a material. Fire retardant coatings behave in unique ways depending on their chemical make-up and application.

• Fire-Retardant Coatings

• Fire Protection Rating

• Fire-Resistant Materials

• Ignition Resistant Construction

Answer explanation

See page 154
