Overview

Our caution non ionising radiation sign printing starts with one job: the sign warns of non-ionising radiation such as from radio or microwave equipment. It earns its place in industrial equipment, rooftops with antennas and plant rooms.

Where to fix it

At the access point to the equipment. Give people time to react: the sign should come before the hazard, not after it.

Before you order caution non ionising radiation sign printing, think about how far away people will be. 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. Long corridors, yards and car parks need the bigger sizes.

What the sign says

It reads "Caution Non-Ionising Radiation". Yellow triangle, black border: the shape everyone reads as "watch out". The layout is a yellow triangle above black wording, plus the ISO 7010 W005 symbol (non-ionizing radiation). The CAUTION heading tells people to watch out; the line beneath says for what.

Caution non ionising radiation sign printing: choosing the board

There is a board for each kind of spot in our caution non ionising radiation sign printing range:

  • 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.

A warning sign sits alongside your risk assessment and other controls; it does not replace them.

Under the Health and Safety (Safety Signs and Signals) Regulations 1996, employers put up a safety sign wherever a risk is still there after other controls. Warning signs take the yellow triangle with a black edge.

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 non ionising radiation sign printing job is printed to order and sent out from the UK. We charge £7.95 to send it anywhere on the UK mainland, and nothing once your goods come to £100 or more after discounts. Mainland Highlands postcodes add £10; Northern Ireland, the islands, the Isle of Man, the Channel Islands, Scilly and the Isle of Wight are quoted. Full details are on the delivery page.

Also worth a look: warning 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.

SizeReadable 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 non ionising radiation sign printing.

Which size of Caution Non-Ionising Radiation sign can be read from across the room or yard?

Measure the distance first, then match it: 8 m calls for A4 (210 × 297 mm), 12 m calls for A3 (297 × 420 mm), 17 m calls for A2 (420 × 594 mm) and 24 m calls for A1 (594 × 841 mm). Traffic, dim corners or glare all justify going one size bigger. The largest, A1 (594 × 841 mm), is the choice for wide open spaces.

Is the symbol on this sign an ISO 7010 one?

Yes: W005, Non-ionizing radiation. The "Caution Non-Ionising Radiation" text sits alongside it, and the pictogram is taken from public domain artwork.

Where should the "Caution Non-Ionising Radiation" message go so people act on it?

The right place is at the access point to the equipment. Walk the route yourself and make sure it is seen from the direction people come.

Is there a legal rule behind the Caution Non-Ionising Radiation sign?

The Health and Safety (Safety Signs and Signals) Regulations 1996 say employers must put up a safety sign when a risk remains that other measures cannot remove. A warning uses the yellow triangle with a black border. For the "Caution Non-Ionising Radiation" sign, your risk assessment is what decides the exact positions.

Is it possible to order a batch of these?

Of course. Set how many you want at checkout and we make each one for your order. For a large run of assorted signs, send the list through the Get a quote page and we will price it together.

What do I need to mount the "Caution Non-Ionising Radiation" sign?

For a rigid board, either double-sided sign tape or a drill and screws. Vinyl needs nothing extra: peel and stick onto a clean, dry, smooth surface.

Which material works best for the "Caution Non-Ionising Radiation" sign?

Inside, 3mm Foamex is light and quick to put up. Self-adhesive vinyl sticks to smooth doors, glass and machines. If it is going outside, or needs to take knocks, choose Dibond aluminium composite.

What is the delivery time on the "Caution Non-Ionising Radiation" sign?

Count 4 working days on Standard before it ships, then 1 to 3 working days by courier with email tracking. 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 Non-Ionising Radiation Sign?

Picked the way the page first loads, with A4 (210 × 297 mm) and self-adhesive vinyl, the Caution Non-Ionising Radiation 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 Non-Ionising Radiation Sign?

Allow 6 working days on Saver, 4 on Standard or 2 on Express before the Caution Non-Ionising Radiation 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 Non-Ionising Radiation 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. 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 Non-Ionising Radiation Sign starts from £5.02.

Vinyl, Dibond or Foamex: which should we pick for a Caution Non-Ionising Radiation Sign?

Decide by where "Caution Non-Ionising Radiation" is going and how long it has to last. Staying outside for years, or somewhere busy where it may get knocked? 3mm Dibond aluminium composite, with metal skins, is the tough one. Indoors or under a porch? 3mm Foamex gives a light, smooth board. Going straight onto a door, window or smooth wall? The self-adhesive vinyl sticks flat with no drilling.

Which size of the Caution Non-Ionising Radiation Sign can people read from further away?

Rough reading distances for "Caution Non-Ionising Radiation": 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.

Which sizes can the Caution Non-Ionising Radiation Sign be printed in?

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 this page, Caution Non-Ionising Radiation Sign starts from £5.02.

What message is a Caution Non-Ionising Radiation Sign giving?

Start with the symbol on "Caution Non-Ionising Radiation". W005 is the ISO 7010 pictogram for non-ionizing radiation, 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 lab, a clinic or an equipment room.

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. Nothing is printed ahead of time: each sign is made to order for you. On its opening option, Caution Non-Ionising Radiation 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 Non-Ionising Radiation 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.

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. 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 Non-Ionising Radiation Sign leaves us after 6 working days on Saver.

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 Non-Ionising Radiation" the sizes are A4, A3, A2 and A1. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all.

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. Before delivery, this sign costs from £5.02. On this page, Caution Non-Ionising Radiation Sign starts from £5.02.

Our event is close. Can the Caution Non-Ionising Radiation Sign be rushed?

Yes. Choose Express and the Caution Non-Ionising Radiation 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.

Can I send a Word or Canva file for the Caution Non-Ionising Radiation Sign?

Word, PowerPoint and Canva are a fair place to start, but export a high quality PDF from them before uploading. Our first choice is always a PDF at the ordered size with fonts embedded or outlined, followed by AI, EPS or SVG, then high resolution JPG, PNG or TIFF. You can add three files, each up to 25 MB, on this page, or upload them after ordering from the email we send. 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 this page, Caution Non-Ionising Radiation Sign starts from £5.02.

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. Make the artwork for this sign the same size as the one you order, such as A4 (210 × 297 mm). 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 Non-Ionising Radiation Sign starts from £5.02.

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. For reference, Caution Non-Ionising Radiation Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).

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 this page, Caution Non-Ionising Radiation Sign starts from £5.02.

Can the wording on a Caution Non-Ionising Radiation Sign be changed, or our logo added?

Yes. To reword "Caution Non-Ionising Radiation" 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. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.

Does the Caution Non-Ionising Radiation 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. For reference, Caution Non-Ionising Radiation Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).

What thickness is the Caution Non-Ionising Radiation 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. Material choices for Caution Non-Ionising Radiation Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

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: Ice Warning Sign and Caution Pinch Point 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 Non-Ionising Radiation 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 its opening option, Caution Non-Ionising Radiation Sign leaves us after 6 working days on Saver.

Will a Caution Non-Ionising Radiation Sign cope with rain and wind outdoors?

Rain is rarely the problem for "Caution Non-Ionising Radiation"; 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 Non-Ionising Radiation Sign?

To mount "Caution Non-Ionising Radiation" 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 Non-Ionising Radiation 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 this page, Caution Non-Ionising Radiation Sign starts from £5.02.

Do we legally have to display a Caution Non-Ionising Radiation Sign?

Your risk assessment answers that one for "Caution Non-Ionising Radiation". 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 W005.

I have spotted a typo after paying. Can it be fixed?

Tell us quickly through the Contact page, quoting your order number. Before production starts we can take a corrected file, or cancel and refund the whole order. After that it cannot be changed. A print that matches your finished design or the file you sent is not a fault, so it pays to read every word and number before you order. 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 Non-Ionising Radiation Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

Next year we will want the same sign again. Is reordering easy?

Very. Choose the same product with the same options and upload the same file, and it is made again exactly as before. Save the final print file somewhere safe, as that makes a repeat order a two-minute job. Before you repeat it, read the wording again: dates, prices, opening times and contact details are the things that go out of date. Nothing is printed ahead of time: each sign is made to order for you. Before delivery, this sign costs from £5.02. Material choices for Caution Non-Ionising Radiation Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

Can I pay for the Caution Non-Ionising Radiation 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. 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 Non-Ionising Radiation Sign starts from £5.02.

Can I send this sign back if I no longer need it?

If it arrives faulty, damaged or not what you ordered, yes: under the Consumer Rights Act 2015 we reprint or refund. A change of mind is different. Each order is made to your specification, and reg. 28(1)(b) of the Consumer Contracts Regulations 2013 takes those goods out of the 14-day right to cancel. Before production starts, though, you can cancel for all your money back. 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 Non-Ionising Radiation Sign starts from £5.02.

How do I work out how many Caution Non-Ionising Radiation 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. 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 Non-Ionising Radiation Sign leaves us after 6 working days on Saver.

I am not sure which options to pick for this sign. Can someone advise me?

Yes. Type your question into the box on this page and a real person replies. Mention where the sign will be used, how long you need it to last and the date you need it by. Answered questions may be shown on the page for other buyers, so leave personal details out of it. Private questions can go through the Contact page, and anything the options here cannot price can go through the Get a quote page. 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 Non-Ionising Radiation Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

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 this page, Caution Non-Ionising Radiation Sign starts from £5.02.

Do I pay delivery on each item in my basket?

No. One delivery charge covers the whole basket, so adding the Caution Non-Ionising Radiation 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.

Should I send my file as RGB or CMYK?

CMYK if you can. An RGB file gets converted to CMYK for printing, and vivid greens, blues and oranges may lose a little brightness on the way. Have a Pantone number for your brand colour? Tell us and we match it as near as the material lets us. Expect a small shift between screen and print either way: a screen shines light at you, while a printed item reflects it. 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 Non-Ionising Radiation Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.

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 Non-Ionising Radiation 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.

Some of our visitors have poor eyesight. Will this sign be easy for them to read?

Three things help most: strong contrast between the words and the background, a plain bold font, and a size that matches how far away people will be. Our standard safety sign layouts use the high-contrast colour pairings laid down for safety signs. Mount the sign at eye height, where it is well lit and not catching glare, and keep the message short. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Make the artwork for this sign the same size as the one you order, such as A4 (210 × 297 mm). For reference, Caution Non-Ionising Radiation Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).

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. Nothing is printed ahead of time: each sign is made to order for you. On this page, Caution Non-Ionising Radiation Sign starts from £5.02.

Could the Caution Non-Ionising Radiation Sign go on a door, say an office or classroom door?

Start with the position: eye level, on the push side or on the wall next to the frame, so the message is still visible with the door open. For the door itself, choose self-adhesive vinyl, which suits painted doors and glass panels. A 3mm Foamex board on foam tape also sits well on a flat door. On a fire door, get the go-ahead from whoever looks after the building before any screws go in. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On this page, Caution Non-Ionising Radiation Sign starts from £5.02.

What is the safest way to clean this sign?

Treat "Caution Non-Ionising Radiation" 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.
