Emergency Exit

The Running Man: What E001 Shows

E001 depicts a white human figure running toward a doorway on a green rectangular field. It marks an emergency exit, or a point on the escape route leading to one, in the left-hand orientation: the figure moves toward a door frame on the left side of the sign. Green is the ISO 3864-1 safe-condition color, reserved for signs that show people where safety lies rather than what to avoid, and the white-on-green combination is chosen for legibility in poor visibility.

The running-man pictogram originated in Japan, where designer Yukio Ota's figure was selected through a national design competition in the early 1980s after fatal department store fires exposed how badly text-only exit marking served panicked crowds. It entered international standardization through ISO 6309 in 1987 and was carried into ISO 7010, and it is now the default exit symbol across the European Union, most of Asia, Australia, and much of the rest of the world. Its strength is language independence: it communicates the same instruction to every occupant regardless of literacy or native language.

Direction Variants and Arrow Combination

ISO 7010 provides E001 for left-hand situations and E002 as its mirror image for right-hand ones, and both combine with supplementary directional arrows to build a complete escape-route system. The governing convention is consistency: the figure should run in the direction of travel, and any arrow added to the sign must agree with it. ISO 16069, the standard for safety way guidance systems, sets out how escape route components are combined so an occupant moving along the route receives an unbroken chain of directional information.

In practice this means a sign at every point where the route could be misread: each change of direction, each corridor junction, each door that must be passed through, and the final exit itself. National application rules differ on details such as whether an upward-pointing arrow means straight ahead or through the door above, so facilities operating across borders should document one convention and apply it uniformly. A route where one junction uses an up arrow for straight-on and the next uses it for a level change will fail exactly when it is needed.

Green Running Man vs the US EXIT Sign

The United States is the major exception to the running man's dominance. NFPA 101, the Life Safety Code, and the International Building Code require exit signs bearing the word EXIT in plainly legible letters, illuminated at all times and backed by emergency power. The green pictogram is generally permitted only as supplementary marking, or as a primary sign where the authority having jurisdiction specifically approves it. A US facility that replaces its EXIT signs with ISO pictograms alone would typically be cited.

By contrast, EU member states implement Directive 92/58/EEC, which mandates the green rectangular pictogram format that E001 satisfies, and text-only exit signs there are the nonconforming option. Multinational operators commonly resolve the split by following the local code as the primary layer and adding the other format for their international workforce: ISO pictograms alongside EXIT text in American plants, and occasionally EXIT text panels beneath E001 in facilities hosting US-based visitors or auditors.

Photoluminescent and Low-Location Signage

Smoke stratifies at ceiling height, which is precisely where most exit signs hang. ISO 16069 therefore describes low-location safety way guidance: continuous markings and exit signs mounted near floor level along walls, where visibility persists longest as a space fills with smoke. Low-location systems duplicate the high-mounted E001 signs rather than replacing them, giving crawling or crouching occupants a readable path when the upper signage has disappeared into the smoke layer.

Photoluminescent versions of E001 absorb ambient light and continue glowing during a blackout without wiring or batteries, making them a common choice for low-location marking, stairwells, and areas where emergency lighting circuits could be compromised. Requirements tightened after the 2001 World Trade Center evacuation: New York City's Local Law 26 mandated photoluminescent exit path markings in high-rise office buildings, and the International Building Code now requires luminous egress path markings in the exit enclosures of high-rise buildings. Photoluminescent signs need adequate ambient light to charge, so they are unsuitable for spaces kept dark during occupancy.

Read the complete escape-route sign

E001 and E002 are the left-hand and right-hand emergency-exit variants. Use the complete installed wayfinding system, including directional arrows and local instructions. A running figure alone is not enough to infer the full route through a building.

US workplace context

OSHA 1910.37 requires each exit to be clearly visible and marked by a sign reading “Exit,” and provides further requirements for directional marking and sign visibility. Do not assume a downloaded ISO pictogram can replace required exit wording or an approved illumination system.
