In smoke and panic, people don't remember floor plans — they follow signs. Fire safety signage is the cheapest life-safety system in any building, yet it's the one inspectors most often find missing, faded or hidden behind storage. Indian Standard IS 9457 (safety colours and safety signs) and NBC 2016 set out what signs buildings need and how they should look. Here's the practical version.
The Four Families of Safety Signs
- Escape & first-aid signs (green/white): EXIT signs, running-man pictograms, directional arrows, assembly point markers
- Fire equipment signs (red/white): location markers for extinguishers, hose reels, hydrants, call points and alarm panels
- Prohibition signs (red circle-slash): No Smoking, No Naked Flames, Do Not Use Lift During Fire
- Warning & mandatory signs (yellow triangle / blue circle): flammable material, LPG storage, 'Fire Door — Keep Shut'
Using the correct colours and pictograms matters — IS 9457 aligns with international conventions so that anyone, in any language, reads the sign instantly.
Exit & Escape-Route Signage
Every exit and the route to it must be signed so that from any point, a person can see the next directional sign leading outward. EXIT signs go above or beside exit doors; directional arrows go at corridor junctions, turns and staircase entries. NBC expects exit signage to be illuminated — internally lit or backed by emergency power — so it stays visible in a power failure. Mount escape signage at a consistent height where it's visible over head-height obstructions, and never let furniture, plants or festive decorations block sightlines.
Photoluminescent (Glow) Signage & Way-Guidance
Photoluminescent signs charge under normal lighting and glow for hours in darkness — invaluable when power and lighting fail and smoke sits at ceiling level. Because smoke rises, low-level way-guidance (glow strips along skirting and on stair nosings) helps people crawling below the smoke layer find the way out; hotels, hospitals, cinemas and high-rises benefit most. Glow signage needs ambient light to charge, so it complements — not replaces — illuminated exit signs.
Equipment Location Signs
Every extinguisher, hose reel, hydrant landing valve and manual call point needs a sign above it at ~2 m height so the location is visible across a room even when the equipment itself is hidden by crowds, racks or vehicles. Add ID numbers matching your AMC register so audits can track every unit. Extinguisher signs that state the type (ABC/CO₂) also help users grab the right unit for the fire — critical near electrical rooms and kitchens.
Placement Rules & Common Mistakes
- Assembly point sign in the open area, visible from the building exits
- 'Fire Door — Keep Shut' on both faces of every fire-rated door
- Floor number signage inside staircases (firefighters orient by these)
- Mistake: printed A4 'EXIT' paper taped to walls — fades, falls, fails inspection
- Mistake: signs installed once, then blocked by new racks, ACs or hoardings — walk your routes quarterly
- Mistake: mixing arrow conventions (up-arrow should mean 'straight ahead', not 'upstairs' unless at a stair)
Signage is checked in every fire NOC inspection and fire audit. Discreet Fire and Safety Solutions supplies IS 9457-compliant signage — including photoluminescent ranges — with a placement plan for your building across Delhi NCR.
Frequently Asked Questions
Which Indian standard covers fire safety signs?
IS 9457 specifies safety colours and safety signs (aligned with international pictogram conventions), and NBC 2016 sets requirements like illuminated exit signage on escape routes.
What colour should fire safety signs be?
Green/white for escape and exit signs, red/white for fire equipment locations, red circle-slash for prohibitions like No Smoking, yellow triangles for warnings and blue circles for mandatory instructions.
Are photoluminescent signs mandatory?
NBC expects exit signage to remain visible in power failure — achieved with illuminated signs and/or photoluminescent signage. Glow signs and low-level way-guidance are strongly recommended for hotels, hospitals and high-rises.
Where should extinguisher signs be placed?
Directly above each extinguisher at around 2 metres height, so the location is visible across the room even when the unit itself is obscured — ideally with the extinguisher type and an ID number.
