Some where in the back of my mind I seem to remember contents of Table 1005.1 in the past codes used to list ramps in one of the columns.

Is the egress width unit to be used for ramps to be in the Stairways column or the Other egress components column?

Some how I thought it was in the Stairway column but now as the Code reads it appears to be in the Other egress components column.
 
Mark,

The Table is a numerical factor used to determine the required egress width. My question is which column, Stairways column or the Other egress components column, does a ramp fall in?
 
Agree use other egress components but do not forget about 1010.5.1

Less than 50 OL 36 inches more than that 44" minimum.

The minimum dimensions of means of egress ramps shall comply with Sections 1010.5.1 through 1010.5.3.

1010.5.1 Width.

The minimum width of a means of egress ramp shall not be less than that required for corridors by Section 1017.2. The clear width of a ramp and the clear width between handrails, if provided, shall be 36 inches (914 mm) minimum.

1017.2 Corridor width.

The minimum corridor width shall be as determined in Section 1005.1, but not less than 44 inches (1118 mm).

Exceptions:

1. Twenty-four inches (610 mm)—For access to and utilization of electrical, mechanical or plumbing systems or equipment.

2. Thirty-six inches (914 mm)—With a required occupant capacity of less than 50.

3. Thirty-six inches (914 mm)—Within a dwelling unit.

4. Seventy-two inches (1829 mm)—In Group E with a corridor having a required capacity of 100 or more.

5. Seventy-two inches (1829 mm)—In corridors serving surgical Group I, health care centers for ambulatory patients receiving outpatient medical care, which causes the patient to be not capable of self-preservation.

6. Ninety-six inches (2438 mm)—In Group I-2 in areas where required for bed movement.
 
Thanks all. I was thinking it was Other egress components. I did look this morning in the old SBC and they have a foodnote addressing ramps and the factor to use. I forgot we had a copy and should have looked before posting. The SBC put ramps in with corridors also. As you get older and been under all the Codes you forget and get confused. Senior moment.
 
There's also a difference in the assembly seating for differing steepnesses in the ramp (Table 1025.6.2 - 2006). Maybe that's the other table you were thinking about.

But, unless it's smoke protected assembly seating with greater than 5000 seats, the factors for "other" are what is needed.
