Qualified; tested; listed; classified; approved.
Certified is not the same |
|
|
The keys to fire protection are:
(7-3) |
1. Prevention; 2. detection; 3. suppression; 4. compartmentation |
|
|
What is the process of limiting fire and smoke using fire resistive barriers to contain and localize fire, smoke, and other combustion by products so that fire can be suppressed, while allowing occupants safe egress?
(7-3) |
Compartmentalization |
|
|
What is one of the three pillars of a balanced approach to fire protection and is a core strategy recommended by all building and safety codes?
(7-3) |
Compartmentalization |
|
|
What is the reference for barrier standards in the US?
(7-6) |
ASTM E119; UL 263; NFPA 251 |
|
|
What is the criteria, firestop materials and systems should be selected on?
(7-9) |
Qualification testing; installation efficiency; maintenance convenience; future cable MAC; architectural and environmental requirements |
|
|
What is the reference for firestopping test methods in the US?
(7-11) |
ASTM E814; UL 1479 |
|
|
How is hose stream pressure and duration determined?
(7-14) |
by the hourly rating period tested. For three hours and below, the pressure is 207kPa and the duration is 1.5 seconds per square foot |
|
|
What are modular devices that integrate a built-in fire stop system, which eliminates the need to remove or install firestop materials?
(7-23) |
Fire-rated pathways |
|
|
What are nominal sizes for intumescent collars?
(7-25) |
1.5 inches to 6 inches |
|
|
What are some common types of forming or packing materials?
(7-33) |
1. Mineral Wool Batt insulation
2. Glass fiber batting
3. ceramic fiber insulation
4. foam backer rods |
|
|
What is the thickness compressed to after backer rods are inserted the opening?
(7-34) |
25% |
|
|
If the ceiling material is wood, the following fire stop methods can be used:
(7-49) |
1. Sleeve systems
2. Mineral Wool
3. Top coat with fire stop caulking
4. Intumescent Materials |
|
|
Each firestop should be documented, how?
(7-57) |
Label each penetration upon fire stop completion;
take a photo or video of each penetration after labeling and submit to the AHJ |
|
|
Bags shall be tightly packed into openings and always installed with?
(7-33) |
Heavy gauge hexagonal wire mesh (or chicken wire) |
|
|
When pillows are exposed to fire, the matrix reacts in the following:
(7-32) |
Intumesces or swells to provide further sealing; becomes rigid to allow the pillow to withstand the force of a hose stream. |
|
|
Pillows are appropriate for:
(7-32) |
frequent cable changes; a fire watch would otherwise be required during construction |
|
|
What three products are used fro medium to large sized penetration openings?
(7-32) |
pillows, blocks, and bags |
|
|
These are ready to use standard size products that are stacked in an opening or as a wall.
(7-33) |
Intumescent blocks. While blocks can be retrofitted, they are more difficult to remove and replace than other re-enterable products |
