Dear Gary:
This is a Fire and Life Safety Plan Review and is based on the 1985 editions
of the Fire and Life Safety Code (UBC). Mechanical Fire and Life Safety Code
(UMC), Uniform Fire Code (UFC), and other local ordinances and regulations.
Plans are conditionally approved subject to the following items:
1. Gauge of Ducts: Ducts shall be gauged in not less than that
stipulated in the Tables at the end of the Chapter 11 of the Uniform
Mechanical Code.
2. Explosion Vent: Explosion venting shall be provided along the main
run of 10 inch ducting, preferably close to the vacuum unit to relieve
possible explosion that may occur. UMC Chapter 11. This Plans
Examiner would think that a slip joint in the 10 inch piping system
would be a good equivalent unless other provisions have been provided.
3. Velocity, Velocity in piping systems shall be in compliance with
Uniform Mechanical Code Table 11 -A which is 3500 fpm. Please provide
this department and the City of Tigard with calculations showing that
this velocity will be met in 10 inch ducting.
4. Approved Plans on Job Site: One set of approved plans bearing the
stamps of the Tigard Building Department and this office must be
maintained on the project site throughout all phases of construction
and must be made available to building and fire inspectors for
reference during required construction inspections. (UBC Sec. 303)
