Overview
Our caution ammonia sign printing starts with one job: the sign flags chemical hazards and limits who goes in. It earns its place in waste compounds, cleaning stores, plant rooms and chemical stores.
Caution ammonia sign printing: choosing the board
Our caution ammonia sign printing comes on three kinds of board:
- 3mm Foamex, a rigid PVC foam board that screws or sticks up easily and is happiest indoors or out for a season
- 3mm Dibond, aluminium skins on a solid core, the one to pick for a sign that stays outside for years
- self-adhesive vinyl, which sticks flat to smooth walls, doors, glass and machine guards
Inside, Foamex or vinyl does the job. Outside for the long haul, go Dibond.
The message
It reads "Caution Ammonia". Yellow triangle, black border: the shape everyone reads as "watch out". The layout is a yellow triangle above black wording, plus the ISO 7010 W001 symbol (general warning sign). The CAUTION heading tells people to watch out; the line beneath says for what.
Putting it up
On the store door or cage, where it is seen before anyone opens up. Mark the store and the route to it, so the warning is seen before anyone opens a door.
Sizing your caution ammonia sign printing comes down to distance. Reading distance is worked out from the sign’s short side: about a metre for every 25 mm, the distance factor from ISO 3864-1. That makes A4 to about 8 m, A3 to about 12 m, A2 to about 17 m and A1 to about 24 m. Anything read from a distance or a moving vehicle wants the larger sizes.
Match the sign to what is actually stored, and update it if the contents change.
COSHH and the Health and Safety (Safety Signs and Signals) Regulations 1996 both expect areas holding hazardous substances to be marked, so nobody walks in without knowing the risk.
Got artwork? Upload it. No artwork? Use the online designer, or our paid artwork service (1 design, 2 rounds of changes). Either way a person looks over the file first, free. Each caution ammonia sign printing job is printed to order and sent out from the UK. Delivery to a UK mainland address is £7.95, or free once the order passes £100 after any discount (artwork fees are not counted). The Highlands add £10, and addresses in Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, Scilly or the Isle of Wight get a quote. Full details are on the delivery page.
Also worth a look: chemical and hazard signs and everything in safety signs. The guide to safety sign colours covers the choice in more depth.

Which size do I need?
A safety sign must be large enough to read from where people will see it. Our conservative guide, based on the distance-factor method in ISO 3864-1, is about 1 metre of viewing distance for every 25 mm of sign height (the shorter side). Use it with your own risk assessment.
| Size | Readable from up to about |
|---|---|
| A4 (210 × 297 mm) | 8 m |
| A3 (297 × 420 mm) | 12 m |
| A2 (420 × 594 mm) | 17 m |
| A1 (594 × 841 mm) | 24 m |
Well lit or internally lit signs can be read from further away; dim areas need larger signs.
Questions
Quick answers about caution ammonia sign printing.
How big should the Caution Ammonia sign be?
Think about the furthest point someone needs to read it from. For "Caution Ammonia", A4 (210 × 297 mm) for readers up to 8 m away, A3 (297 × 420 mm) for readers up to 12 m away, A2 (420 × 594 mm) for readers up to 17 m away and A1 (594 × 841 mm) for readers up to 24 m away. Those distances assume ordinary light, so if it is gloomy or people are driving past, step up one size.
Is the symbol on this sign an ISO 7010 one?
Yes: W001, General warning sign. The "Caution Ammonia" text sits alongside it, and the pictogram is taken from public domain artwork.
Where is the best place to put the "Caution Ammonia" sign?
Put it on the store door or cage, where it is read before the door opens. Fix it where it will not be hidden by doors, deliveries or vehicles.
Does the law say I must put up a Caution Ammonia sign?
COSHH and the Health and Safety (Safety Signs and Signals) Regulations 1996 expect stores and areas holding hazardous substances to be marked. That way people know the risk before they walk in. Your risk assessment is what decides the exact positions for "Caution Ammonia".
Is the price shown for the "Caution Ammonia" sign the full price?
Yes, for the goods. The price you see is the price you pay at checkout. Mainland UK delivery adds £7.95 to the basket, and nothing once the goods reach £100 after any discount code.
Can I buy more than one Caution Ammonia sign?
Yes, change the quantity before you check out; every sign is made to order. Need a big mix of different signs for a school, club or site? Use the Get a quote page. Postage to the UK mainland is £7.95 per basket, not per item, and free when your goods total £100 or more.
Asked by buyers
How cheaply can I get hold of the Caution Ammonia Sign?
Picked the way the page first loads, with A4 (210 × 297 mm) and self-adhesive vinyl, the Caution Ammonia Sign comes to £5.02. Any other mix of options, a faster turnaround included, gets its own price the moment you choose it, and that figure is what you pay at checkout. Only delivery is left to add. On its own the opening price of £5.02 would add £7.95 for mainland delivery; reach £100 of goods and that goes to zero.
Which turnaround speeds can I choose for the Caution Ammonia Sign?
Allow 6 working days on Saver, 4 on Standard or 2 on Express before the Caution Ammonia Sign is handed to the courier, based on the options the page opens with. Weekends and bank holidays are not counted, and nothing starts until the order is paid and the artwork is confirmed. Pick another size or material and the days beside each speed update, sometimes by a day. After it leaves us, the courier normally delivers in one to three working days and you get the tracking link by email.
Which artwork services are offered with the Caution Ammonia Sign?
Several routes, all chosen under Artwork on this page. Send your own finished file (no charge), we set your words and logo on a tidy layout, called typesetting (£15), we design it from your brief (£35), we redraw a blurry or low quality logo as sharp vector art (£30) or we create a brand new logo (£50). Typesetting and design from a brief each come with one first draft and two rounds of changes. The fee is the same whatever quantity you order and shows separately in the basket. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
Which is the smallest and which the biggest sign I can order here?
The table has 4 sizes. At the small end, A4 (210 × 297 mm) costs from £5.02; at the top, A1 (594 × 841 mm) costs from £15.12. Each figure is for the cheapest set of options at that size. Unsure? Measure where it will go and check the view from the spot people will stand. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
Which size of the Caution Ammonia Sign can people read from further away?
Rough reading distances for "Caution Ammonia": about 8 m for A4, 12 m for A3, 17 m for A2 or 24 m for A1. The rule of thumb behind them: each 25 mm of height buys roughly one metre of distance. If the light is poor, or people pass quickly on foot or at the wheel, go for the next size up. The figures use the distance factor from ISO 3864-1, and your own risk assessment should settle the final choice. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all.
What message is a Caution Ammonia Sign giving?
Start with the symbol on "Caution Ammonia". W001 is the ISO 7010 pictogram for general warning sign, so even someone without much English gets the gist at a glance. The design follows the warning sign pattern (a black-edged yellow triangle), used to flag up a hazard. That colour and shape code is laid down by the 1996 Safety Signs and Signals Regulations. Typical spots: a cleaning cupboard, a pool plant room or a garden centre store.
Can I mix different safety signs in a single order?
You can. Each sign gets a separate basket line, with whatever size and board suit it, and you pay once at the end. Delivery is charged per order, not per sign: £7.95 to the UK mainland, or free once the goods come to £100 or more. For "Caution Ammonia" the sizes are A4, A3, A2 and A1. Nothing is printed ahead of time: each sign is made to order for you.
Could you price an A2 (420 × 594 mm) sign for me?
From £9.33, with the cheapest settings and the Saver service. Material by material, it is 3mm Foamex at £42.91, 3mm Dibond aluminium composite at £61.17 and self-adhesive vinyl at £9.33. Add £7.95 for UK mainland delivery, or nothing at all once the goods reach £100. Select it on the page and swap materials, finishes and speed to watch how the figure moves. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
I am not a business. Can I buy just one sign?
Of course. Anyone can order, with no trade account and no minimum beyond one. Prices for the Caution Ammonia Sign begin at £5.02, checkout works without an account and you pay by card. Parents, clubs, churches and small shops order single items all the time. On its own the opening price of £5.02 would add £7.95 for mainland delivery; reach £100 of goods and that goes to zero.
And the largest sign, A1 (594 × 841 mm): how much is that one?
From £15.12, with the cheapest settings and the Saver service. Material by material, it is 3mm Foamex at £63.13, 3mm Dibond aluminium composite at £88.40 and self-adhesive vinyl at £15.12. Add £7.95 for UK mainland delivery, or nothing at all once the goods reach £100. Select it on the page and swap materials, finishes and speed to watch how the figure moves. Before delivery, this sign costs from £5.02. On this page, Caution Ammonia Sign starts from £5.02.
Could the total go up after I reach the checkout?
No surprises: what the page shows for this sign is the goods figure you pay at checkout. Delivery is the one extra, £7.95 to a UK mainland address, and it drops away when the goods reach £100 after discounts. Paid artwork help shows up as its own basket line, so you can check each amount before paying. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. Nothing is printed ahead of time: each sign is made to order for you. On this page, Caution Ammonia Sign starts from £5.02.
I need several signs, some in different sizes. How do I buy them?
Each price on the page is for a single sign in the size and material chosen. Put the number you want in the box beside Add to basket and the total multiplies. For a different size or material, add it as a separate line; the basket keeps them apart. An artwork fee is charged once per line, whatever the quantity, and choosing to reuse the artwork from another item in your basket costs nothing more. Very large runs can go through Get a quote. Before delivery, this sign costs from £5.02. Nothing is printed ahead of time: each sign is made to order for you. Material choices for Caution Ammonia Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.
Our event is close. Can the Caution Ammonia Sign be rushed?
Yes. Choose Express and the Caution Ammonia Sign can be on the way in 2 working days on the opening option, for £6.68, where Saver is £5.02 and takes 6 days. Then give the courier one to three working days, and send the artwork with the order, because the clock does not run until the file is sorted. If the date is really tight, message us on the Contact page before paying and we will tell you honestly.
How many pixels does a photo need to print well on this sign?
Close-up items need about 300 dpi at full size. So an A1 (594 × 841 mm) layout wants about 7,016 by 9,933 pixels. Keep lettering and logos as vectors if you can. An image copied off a web page or a social post rarely has enough pixels; if yours looks likely to print soft, our file check flags it. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
Someone else is putting our file together. How does it reach you?
Easiest route: they send the finished file to whoever placed the order, and it gets uploaded after ordering. Up to 3 files of 25 MB each are fine. They can also reach us through the Contact page, as long as they quote your order number so it lands on the right job. Production waits for the checked file, so a late file means a later dispatch date. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
Can the wording on a Caution Ammonia Sign be changed, or our logo added?
Yes. To reword "Caution Ammonia" or add a logo, pick the typesetting option (£15) for your text and logo on a clean layout, or the design-from-your-brief option (£35), then send us the details. Both paid options include one first draft and two rounds of changes. Uploading your own print-ready file costs nothing, and someone on our team looks it over before printing. Leave the safety symbol and its colours untouched, though: altering them makes the meaning less clear. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all.
Will anyone look at my file before it is printed?
Yes, a real person on our team opens every uploaded file and checks the size, the bleed and the resolution. If something is off, you hear from us before anything is made. We print what you send, though, so read the spelling, numbers and dates yourself as well. Making starts when the order and the file are both confirmed. Make the artwork for this sign the same size as the one you order, such as A4 (210 × 297 mm). For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Material choices for Caution Ammonia Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.
Does the Caution Ammonia Sign come in a peel-and-stick version?
It does. Pick self-adhesive vinyl from the material list and it comes as a peel-off sticker. That is handy on a glass shop door, a classroom cupboard, a machine or a smooth painted wall, anywhere screwing a board up would be awkward. Wipe the spot, let it dry, then press it down from the centre outwards to push the air away. On rough brick or dusty surfaces, a board will hold better. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Material choices for Caution Ammonia Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.
What thickness is the Caution Ammonia Sign, and does it feel sturdy?
Three millimetres, whichever board you go for. Pick self-adhesive vinyl instead and you get a thin film that lies flat against whatever you stick it to. Dibond feels stiff because a plastic core is sandwiched between two thin aluminium sheets, yet it is still simple to screw or stick up. Foamex is foamed PVC, so it weighs very little in the hand. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. For reference, Caution Ammonia Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
We are putting up a full set of signs at our premises. Which ones sit well next to this one?
A school corridor, a shop floor or a club house rarely needs just one notice. Two that often go up beside this one: Caution Asbestos Sign and Caution Battery Acid Sign. Keep every sign in one board type so the set matches, look up sizes and prices on each page, then check out once: one delivery charge for the whole basket, free over £100 of goods. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
It gets dark early in winter. Can people still read the Caution Ammonia Sign in the evening?
Not in pitch darkness. Pick Foamex, Dibond or vinyl sticker and it is the same story: nothing on this page reflects headlights or glows by itself. Fix it where a street light, porch light or security lamp already shines, or fit a small light above it. Where a risk assessment asks for photoluminescent or reflective signs, those need to come from a specialist maker rather than from us. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Before delivery, this sign costs from £5.02. On this page, Caution Ammonia Sign starts from £5.02.
Will a Caution Ammonia Sign cope with rain and wind outdoors?
Rain is rarely the problem for "Caution Ammonia"; sunshine is. Every printed sign fades slowly in strong sun, so make a habit of checking outdoor ones and renew any that have faded too far. Dibond is the board to pick for a permanent outdoor home. Foamex copes with a covered spot but prefers life indoors. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
What is the easiest way to put up a Caution Ammonia Sign?
To mount "Caution Ammonia" on a wall, drill a hole near each corner of the board and screw it on with a washer under each head; stop once it feels snug, as Foamex in particular does not like being overtightened. Where drilling is not wanted, say on a painted door or a smooth wall inside, double-sided foam tape or sticky pads hold it well. For a fence, make a hole at each corner and loop cable ties through. The vinyl one needs no tools: peel off the backing and press it on once the surface has been wiped and dried. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
Does the material change the price of the Caution Ammonia Sign?
Taking the smallest size, A4 (210 × 297 mm), as the example: self-adhesive vinyl at £5.02, 3mm Dibond aluminium composite at £40.79 and 3mm Foamex at £27.79. Larger sizes follow a similar pattern, and the full grid sits in the size table further up the page. Think about where it is going first: a cheap material in the wrong spot can end up costing more. Before delivery, this sign costs from £5.02. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
Do we legally have to display a Caution Ammonia Sign?
Your risk assessment answers that one for "Caution Ammonia". Where it shows a risk still remains after other steps, the 1996 Safety Signs and Signals Regulations say an employer must signpost it, and that applies to a cafe with two staff as much as a factory. Signs back up the other measures you take; they are never a substitute for them. The symbol on this sign follows ISO 7010, reference W001.
We need a few different designs. Do they each need their own order?
No. Each design goes into the basket as a separate line with its own file or online design, and you pay for them all in one checkout. Delivery is counted once for the whole order and costs nothing when the goods reach £100. If two lines share the same artwork, pick the artwork option that reuses a file already in your basket, so any design fee is only paid once. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. Before delivery, this sign costs from £5.02. Material choices for Caution Ammonia Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.
Our club needs a big batch of signs, or an odd size. Can you price it?
Yes. Fill in our Get a quote page, giving the size, how many, the material, when you need it and the delivery postcode, and attach your artwork if it is ready. A price comes back to you by email. Get a quote is also how delivery to Northern Ireland and the islands gets priced. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. Before delivery, this sign costs from £5.02. Material choices for Caution Ammonia Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.
Do I have to register before I can buy?
There is no need to sign up. Pay as a guest with a bank card, handled securely by Stripe, and you still get an order confirmation email and a tracking email on dispatch. An account is optional; it just keeps your order history in one place. Before delivery, this sign costs from £5.02. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
Can I pay for the Caution Ammonia Sign by card as a guest?
Yes. Guest checkout is fine, and any debit or credit card works. Stripe processes the payment for us, which keeps your card number off our system entirely. We begin making this sign once the payment has cleared and the artwork is confirmed. Large or out of the ordinary jobs can be quoted first from the Get a quote page. Before delivery, this sign costs from £5.02. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
I am ordering this sign for a school or charity. Do I need to open an account?
No account is needed. Guest checkout lets a parent, volunteer or club secretary order once and pay by debit or credit card through Stripe. The price you see is the price you pay at checkout, and the confirmation email you receive lists the items and the amount paid for your records. If the committee needs a price agreed before anyone pays, the Get a quote page is the better starting point. Nothing is printed ahead of time: each sign is made to order for you. Before delivery, this sign costs from £5.02. For reference, Caution Ammonia Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
How do I work out how many Caution Ammonia signs to order?
Picture someone arriving for the first time. Every door they could come through, every approach to the risk and every corner where the route bends is a place for a sign. Large sites and long corridors usually need repeats, with bigger versions where people read from a distance. Put matching signs on a single basket line and raise the quantity; different sizes or materials go on lines of their own. Before delivery, this sign costs from £5.02. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On this page, Caution Ammonia Sign starts from £5.02.
Who looks after me once I have bought the Caution Ammonia Sign?
FatPrint does, from start to finish. We take your order and payment, a person on our team checks your file, and the Caution Ammonia Sign is made to order for you rather than taken off a shelf. It then goes to you by courier, with tracking sent by email. Questions before or after ordering go through the box on this page or the Contact page, and a person replies.
Do I pay delivery on each item in my basket?
No. One delivery charge covers the whole basket, so adding the Caution Ammonia Sign to other items does not add a second one. It is £7.95 to a UK mainland address and nothing once the goods total £100 after any discount code. Using the same design on two items? Pick the reuse-artwork option on the second one and you pay the artwork fee just once. Each line keeps its own size and quantity.
Our treasurer needs a receipt for the accounts. What do we get?
Keep the order confirmation email we send: it itemises the purchase and the payment, and works as a plain receipt for your records. The total at checkout for this sign is the goods price on the page plus delivery, so the email matches what left the account. Need something more formal for an audit or a grant claim? Message us from the Contact page with your order number. Nothing is printed ahead of time: each sign is made to order for you. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
The parcel turned up damaged. How do I sort it out?
Take photos of the damage and the box it came in, then send them through the contact form within 48 hours of delivery, with your order number. Hold on to the item rather than posting it back; we reply and arrange a reprint or refund. This sits alongside your legal rights, which the returns page covers. Choose Saver and this sign leaves us after 6 working days; Express brings that down to 2. Before delivery, this sign costs from £5.02. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
Bleed and dpi mean nothing to me. Can I still get printing done?
Yes. You do not need any print knowledge to order the Caution Ammonia Sign. Send us your words and logo with the typesetting option (£15) and we build the layout, then you get a first draft and two rounds of changes. Whatever you choose, a real person looks at the file before printing.
Does a Caution Ammonia Sign come upright or wide?
"Caution Ammonia" is laid out in portrait format, available as A4, A3, A2 and A1. Upright layouts fit doors, posts and narrow bits of wall. Need it turned the other way? Choose one of the design options and we will rearrange it for you. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all.
What if A1 (594 × 841 mm) is still too small for the Caution Ammonia Sign?
We can still help. Put the size you need, the material and the quantity into the quote request form and we will send a price. For reference, the listed range ends at A1 (594 × 841 mm), and that size costs £15.12 or more. Bear in mind that anything past A0 goes by oversize courier, a one-off £15 on the order. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
The spot gets full sun all afternoon. Could this sign warp in the heat?
Foamex can, Dibond will not. A big, thin Foamex board warms up in direct sun and may bow, especially with fixings only at the corners. Dibond has aluminium faces and keeps its shape, so it is the sensible pick for a long-term outdoor sign. With Foamex, more fixings across a flat wall, or a thicker board, helps it stay straight. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Before delivery, this sign costs from £5.02. On its opening option, Caution Ammonia Sign leaves us after 6 working days on Saver.
What is the safest way to clean this sign?
Treat "Caution Ammonia" gently: a soft cloth and soapy warm water, a rinse, then a dry. Strong cleaners, solvents and scourers can take the shine off the print or lift it, so leave them in the cupboard. Store spares flat, not leaning, to stop them bowing. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.

The star rating is the average of every published review. We never pay for reviews or give discounts or gifts in return for them.
Reviews show the reviewer's first name and initial. To have your own review taken down, contact us.
