Firestopping is:Firestopping is:
Passive Compartmentation
Prevention:
Suppression:
Containment:
The fire is not permitted to start.
The fire is extinguished after it is started. This is known asActive Suppression.
Sometimes referred to as Passive Compartmentation. The fire is prevented from progressing to another area. This is also known as“PASSIVE” fire protection.

ASTM E814 (UL 1479): Fire Test for Through-Penetration Firestops
• Main Criteria for Through-Penetration Firestop Systems:
– T-Rating: Max. temp. rise of 325 °F above ambient on the non-fireside
– F-Rating: Prohibits flame passage through the system for the duration of the fire test.
– L-Rating: Amount of air leakage
– Hose Stream Performance Required (UL Canada Optional)

A firestop system is a specific construction consisting of a wall or floor assembly, a penetrating item passing through an opening in the wall or floor assembly, and the materials designed to prevent the spread of fire through the openings.

Time is the key in Fire Protection Systems. In construction of buildings, fire-rated walls
and floors of various materials have requirements of being penetrated by many
different items such as pipes, cables and HVAC ducts. These constructions require the correct through penetration (Firestop )
system to provide the fire protection needed.

Firestop systems are not merely the tube of caulk bearing the UL classification symbol.
The firestop system consists of a TESTED and APPROVED method of installation which includes size of opening, maximum penetrating item number and size, depths of forming material and or sealants or firestop devices required.
