A recent CROSS Safety Report discusses how building close down procedures that include isolating automated water systems might result in the drying out of green walls, thus presenting a significant fire hazard in external walls. If the vegetation is allowed to dry out, it may become a fuel for fire.
This risk could also arise through a faulty system or poorly maintained system, resulting in the same drying out of green walls.
It is probably not currently on people’s radar that irrigation may fall under the same category as sprinklers or fire alarms, so fire strategies and fire risk assessments need to reflect its importance.
