Floor Marking Tape Colours: What Each Means and a Simple Plan
India has no law that fixes floor marking colours. So many warehouses invent their own scheme. Yellow means walkway in one shed and danger in the next, and a new picker has to learn the floor all over again at every job.
My advice is to use the scheme most of the world already follows. Yellow for walkways and traffic lanes. White for equipment positions. Green or blue for stock. Orange for goods on hold. Red for rejects and fire equipment. Stripes for hazards and keep-clear areas. Then stop. Six or seven meanings are enough for any warehouse I can imagine.
Where do these colours come from?
There are three sources, and it helps to know which one says what.
- ISO 3864-1, and India's own IS 9457 (Safety Colours and Safety Signs), which is based on it. These standards give the safety colours their meaning. Red means prohibition, stop and fire equipment. Yellow means warning. Blue means a mandatory action. Green means a safe condition, such as an exit or first aid point. They are written for signs, but every floor scheme borrows from them.
- The US rule OSHA 29 CFR 1910.144. It uses red for fire protection equipment, danger and stop buttons, and yellow for caution and physical hazards. OSHA separately requires permanent aisles to be marked, but it does not fix floor colours or line widths.
- The common 5S colour convention used by safety suppliers around the world. White, green, blue, orange and the striped patterns mostly come from here. It is a convention, not a law.
In India, the Factories Act, 1948 asks for floors, passages and gangways that are sound and kept free of obstruction. It leaves the colours to you.
So in this post I use ISO 3864 and IS 9457 for the safety meanings, the OSHA rule for red and yellow, and the 5S convention for everything else.
What does each colour mean?
| Colour | Use it for | Example in an Indian warehouse |
|---|---|---|
| Yellow | Walkways, aisles, traffic lanes | The walking path from the gate to the packing tables |
| White | Equipment and fixture positions | Where the packing table, weighing scale and hand pallet truck belong |
| Green | Finished goods, ready to ship | Packed orders waiting for the courier pickup |
| Blue | Raw material or incoming stock | Supplier cartons waiting to be put away |
| Orange | Goods on hold for checking | Returns waiting for quality inspection, inward stock before the GRN check |
| Red | Rejects, scrap, damaged goods | Returned items not fit to resell, the red-tag area |
| Red and white stripes | Keep clear for safety | In front of fire extinguishers, hydrant points and electrical panels |
| Black and yellow stripes | Physical hazard | Dock edges, ramps, steps and the base of pillars |
Some plants use green for raw material and blue for finished goods. Either is fine. What matters is that one building uses one meaning, written down.
We see the same idea in food packaging. We sell veg marking tape for cloud kitchens, and it works only because everyone in India already agrees what a green dot means.
How do you plan the colours for your floor?
Here is the plan I would follow for a small warehouse or packing unit.
- Draw the floor on paper first. Mark the gate, dock, racks, packing tables, returns corner and every fire extinguisher and electrical panel.
- Mark the walkways in yellow. A 2 inch line works well for pedestrian paths. For forklift lanes, many sites use a wider line of 3 to 4 inches so drivers see it from a distance.
- Mark red and white stripes in front of every fire extinguisher, hydrant and electrical panel. This is the one zone I would never skip.
- Mark the stock zones: blue for inward, green for dispatch, orange for hold, red for rejects.
- Put black and yellow stripes on dock edges, ramps and steps.
- Put up a colour chart at the entrance, in Hindi and English. Explain it to every new person on the first day, including the temporary staff hired for the festive season.
- Walk the floor after 30 days. Move the lines that people keep ignoring, because they are usually in the wrong place.
Never let colour carry the full message. Some people cannot tell red from green easily, and a faded line can look orange. Add a printed floor label or a sign with words near every zone.
Which mistakes make a colour scheme useless?
- Using too many colours. Ten meanings are impossible to remember.
- Using yellow for everything because it was the only roll in the store.
- Painting red lines along walkways. Red should mean stop, fire or reject.
- Marking the space in front of a fire extinguisher, then stacking cartons on it. A marking that nobody respects is worse than no marking.
Where does PackSmith fit?
I will be upfront. Our PackSmith floor marking tape is yellow, 2 inches wide, in 25 m rolls. That covers the biggest part of most floor plans: walkways, aisles and lane edges. It does not cover the red, green or striped zones.
For the other colours, hazard stripes or temporary barricading tape, write to us with your floor plan. We make tapes at JPPL and will tell you what we can supply and what you should buy elsewhere.
Before the first roll goes down, read our notes on applying floor tape so it lasts.
Send us a phone photo of your hand-drawn floor plan, and we will work out how many rolls of yellow you need.
