Evacuation plans — what a building must have

An evacuation plan is not a drawing for a folder but a sign on a wall read under stress. That difference decides whether the plan works.

The duty to hold an evacuation plan follows from fire safety regulations and is established for the specific building, through its fire safety design and classification. So the first question is never "what does a plan cost" but "what does this building's fire design say" — the escape routes, exits and assembly points a plan shows all come from it.

What is most often missed in practice is not content but legibility. A plan that is the architect's drawing shrunk down, with every partition and dimension, cannot be read in a few seconds. A plan that works has a simplified floor plate, a clearly marked you-are-here position, the direction to the nearest exit and a legend that fits in one glance — and it is always oriented the way the person stands in front of it.

Alongside the plan goes the marking of the route itself: direction signs along corridors and stairs, exit signs and equipment that has to be findable in the dark. Photoluminescent signage is therefore not an extra but part of the same system — the plan says where, the signs lead while you walk.

What this covers

Per-floor plans

Simplified floor plate, observer position, routes and exits, legend and assembly point.

Plan orientation

The plan is turned to match where it hangs, not to north on the drawing.

Placement at decision points

At entrances, lifts, stairwells and wherever a corridor branches.

Escape route marking

Direction and exit signs along the whole route, photoluminescent where required.

Equipment marking

Hydrants, extinguishers, call points and power isolation points.

Updates after refit

Revising plans when the layout changes, without remaking the whole set.

Frequently asked questions

Its content comes from the building's fire safety design. We do the graphic production and installation — a plan that can be read, and the route marking that goes with it. Where no fire design exists or it is out of date, we say so before starting.

Where people stop and choose a direction: at entrances, by lifts and stairs, and on garage levels. Exact positions are fixed by walking the building, because a plan behind an open door does not exist.

The plan is updated. On buildings where we hold a maintenance arrangement this follows a change notice; otherwise on request, and only the affected floor is reissued.
