Fire Safety Door Do Not Obstruct Do not Keep Open

Fire safety door, do not obstruct, do not keep open — the standard plate, made at 600 x 100mm horizontal. This is the one most buildings order in quantity, because it fits a standard door stile and sits comfortably above or beside the hardware.

Fire doors form part of a building’s fire-resisting construction, and they only work shut. The plate exists for the person who props one open for ventilation or convenience, and for the certifier who has to confirm the building’s fire safety measures are in place and identified.

Composite ACM in white or silver brushed at $45, satin natural anodised aluminium at $50.

Fire doors are commonly signed on both faces where both sides form part of an exit path, so count leaves rather than doorways. A four-storey building with two fire stairs will typically run to twenty or thirty plates once stair, airlock and services doors are included — which puts most orders past the first quantity tier on its own. The same legend is made at 600 x 165mm if you need a larger format for a wide or distant door.
