"Touch": The perimeter area beyond the sidelines of the playing area, but between the goal lines. "Touch-in-goal": The perimeter areas behind each goal line outside of the playing area. Some may refer to a ball which crosses the dead-ball lines as "dead", rather than touch-in-goal. For the purposes of determining if a ball is "out-of-bounds" (i.e. has left the playing area), the perimeter area extends indefinitely away from the playing area. When a ball or player goes into touch, a lineout throw is generally awarded to the opposition at the spot on the sideline where they left the field. Exceptions include a kick out "on the full" (i.e. the ball did not land in the field-of-play before going into touch) in which case the lineout would still take place on the sideline but back in line with where the ball was kicked, or when a team takes a free kick from a penalty where they would retain the right to throw-in. The perimeter area should be clear and free of obstructions and heavy, solid objects which could pose a danger to players for at least 5 metres from the playing area, according to the Laws. Players often leave the playing area whether accidentally or due to being forced off of the field, sometimes sliding or needing to slow down from a sprint. Many venues at elite levels leave larger spaces around the field to accommodate fitter and faster (or heavier) players. Fixed cameras on tripods and advertising hoardings are often the main culprits for injuring players in the perimeter area. Flag posts Also required in the perimeter area are a set of 14 flag posts, each with a minimum height of 1.2 metres, marking the intersections of certain lines or other nominated distances. These are generally a plastic pole on a spring loaded or otherwise soft base, sometimes with a flag on top, covered in foam padding. Others may be moulded plastic or disposable cardboard. At lower levels, these flags may not be used, but are still specified in the Laws. Flags are placed as follows: One flag post at each intersection of the touch-in-goal lines and the goal-lines (4 flags total) One flag post at each intersection of the touch-in-goal lines and the dead-ball lines (4 flags total) One flag post positioned 2 metres outside of both of the sidelines, in line with both of the 22-metre lines (4
