In NFPS 130 (NFPA 2003), other parameters are also suggested, such as air velocity, temperature, radiant heat flux, toxicity, and other sub-lethal smoke effects (Gann 2004).
While previous studies and some building codes have suggested a visibility of 30 ft (10 m), NFPS 130 (NFPA 2003) suggests a visibility of 100 ft (30 m) for illuminated signs and 30 ft (10 m) for doors and walls.
NFPS 130 (NFPA 2003) specifies the exiting time requirements for a station as follows: (1) the exiting time for the platform is four minutes or less and (2) the exiting time from the most remote point in the station to a point of safety is six minutes or less.
Given the "hydraulic" flow approach in NFPS 130 (NFPA 2003), this result suggests that consideration not only of the accessibility of the stairways but also of the "area accessibility" is important in predicting exiting time.
The same circulation capacities as in NFPS 130 (Table 1) are applied.
In general, the STEPS simulation results are consistent with the NFPS 130 (NFPA 2003) results.
Table 4 compares the predicted exiting times with those of case 5 by NFPS 130 (Table 3).
This is used in a parametric study applying the NFPS 130 (NFPA 2003) exiting calculation approach.
A comparison has also been made between the NFPS 130 (NFPA 2003) results and those predicted by the micro-simulation model STEPS.

I believe this is also one of the objectives of the required Public Address (PA) system in NFPS 130 (2003).
