From the Argyle website .....
Following a recent review of safety at Home Park by our partners, including Plymouth City Council and Devon & Cornwall Police, a potentially dangerous practice by spectators in some seats has been identified.
The wall in front of the seats immediately in front of the various vomitories around the ground is at the regulation height for people walking to, and sitting in, their seats.
However, it is not of the regulation height for people standing to watch the game. There is an increased risk of falling when standing next to this wall and, consequently, of suffering a serious injury.
Home Park is an all-seater stadium. By buying a ticket and entering the ground, spectators agree to abide by the ground regulations; these regulations forbid persistent standing.
To maintain our enviable safety record, we will continue to enforce this regulation and we ask supporters to please refrain from standing persistently. Failure to do so could result in ejection from the ground.
Your assistance in this matter is very much appreciated.
