Scenario 1: Retrofit
Joe from
"Joe's Hospital Group" calls your office. He is concerned about some
cables penetrating fire rated walls and saw you listed as a Certified
Installer on the Unique Fire Stop website. The Joint Commission
will pay him a visit soon and he is about to panic. He is interested
in the Split sleeve System. Can you help
him? Joe has (50) Cat 5 UTP cables that are routed through a fire
wall with (4) sheets of 5/8" fire rated gypsum. The cables are
.20"
in diameter. The holes look a lot like the first picture on the Split Sleeve
System Installation Pictorial. Use "Firestopping by the Numbers" to answer
the following:
1. What is
the rating of the barrier?
2. What UL
System # did you select for this job?
3. What %
cable load is permitted with this Listing?
4. How
much intumescent putty should be packed in the ends?
5. Does the
listing require mineral wool batt insulation as packing?
6. What
size Split Sleeve did you spec for this job?
7. How
will you go about seeking pre-approval from the AHJ?
8. Why take
a digital photo when finished?
9. What is
a MSDS?
10. What
are the dimensions of the SSS-4 washers?
