So the report identifies a major contributing factor to the lack of egress being the narrowing of Leppings Lane, largely due to double stacked coaches. This narrowed the available egress space from 17m to 8 meters. "Using Point C, 8 metre width line, the available flow rate is now around 656 ppm" As we all know Leppings Lane is temporarily closed by SYP which allows for these generous flow rates.
So now we will be exiting almost half the ground onto the pavement on a busy dual carriageway. The pavement is 3m at its widest point and almost half that in other areas (at the side of the superstore). If we apply the same flow rate calculations to the 3m pavement we will have a flow rate of 246 ppm, this means it will take 61 minutes for everyone to exit the ground safely from the Kop and North stands.
SYP need to temporarily shut Penistone Rd so we can use the whole carriageway for egress or they have just made the safety of supporters exiting the stadium from the Kop and North stand a whole lot worse.
