Overview
If "Danger 440 Volts" needs saying clearly, this is the sign, and danger 440 volts sign printing is what we do. It flags the voltage behind the door and the shock risk that comes with it, and you will find it in plant rooms, distribution boards, switch rooms and substations.
Reading the sign
It reads "Danger 440 Volts". The DANGER header is saved for hazards that can kill or badly injure, which is why it gets noticed over the everyday caution signs. The layout is a yellow triangle with a heavy DANGER heading, plus the ISO 7010 W012 symbol (electricity).
Putting it up
On the door or cover of the electrical kit. Fix it at eye level on the enclosure, so it is seen before the door or cover is opened.
Sizing your danger 440 volts 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. Pick bigger for car parks, yards and long runs of corridor.
Danger 440 volts sign printing: choosing the board
There is a board for each kind of spot in our danger 440 volts 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.
Anyone working on the equipment should see the warning before they see the kit.
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.

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 danger 440 volts sign printing.
How big should the Danger 440 Volts sign be?
Think about the furthest point someone needs to read it from. For "Danger 440 Volts", 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.
Does "Danger 440 Volts" come with a recognised safety symbol?
It does. The pictogram is ISO 7010 W012, Electricity, drawn from public domain artwork and paired with the "Danger 440 Volts" wording.
Where do I fix the Danger 440 Volts sign?
For "Danger 440 Volts", the usual spot is on the door or enclosure of the electrical equipment. Walk the route yourself and make sure it is seen from the direction people come.
Does the law say I must put up a Danger 440 Volts sign?
The Health and Safety (Safety Signs and Signals) Regulations 1996 call for a safety sign wherever a significant risk is left after other controls. Live electrical equipment is a common case. Where signs go is set by your own risk assessment for "Danger 440 Volts".
Foamex, Dibond or vinyl: which should I choose?
Ask where it is going. Outdoors or somewhere it may get knocked: Dibond aluminium composite. Smooth doors, glass or machinery: self-adhesive vinyl. Anywhere else indoors: 3mm Foamex, which is light and easy to fix.
How do I put the Danger 440 Volts sign up?
The rigid boards arrive without holes. On smooth walls and doors, sign-fixing tape is quickest; otherwise drill the board and screw it to a wall or post, or cable tie it to a fence. The vinyl version is self-adhesive: press it onto a clean, dry, smooth surface.
Could the Danger 440 Volts sign say something different, or carry our logo?
Yes, we can make it as a custom job. Tell us the text you want in place of "Danger 440 Volts", or send your logo. Send the details through the question box on this page or the Contact page.
Asked by buyers
How much will the Danger 440 Volts Sign set me back?
£5.02 is where the Danger 440 Volts Sign starts, set up as A4 (210 × 297 mm) and self-adhesive vinyl on the Saver speed. Change the size, material, extras, quantity or speed and the total on the page moves straight away. The price you see is the price you pay at checkout, with delivery the only thing that can be added. Delivery anywhere on the UK mainland is £7.95 an order, and it costs nothing once the goods come to £100 or more after any discount code (design and artwork fees are not counted).
If I buy the Danger 440 Volts Sign today, when will it leave you?
As the page first opens, the speeds for the Danger 440 Volts Sign are Express 2 working days, Standard 4 and Saver 6, counting Monday to Friday and skipping bank holidays. The count begins once we have your order and a file ready to print. A bigger size or a different material can move it by a day either way; each speed shows its own days as you choose. Tracking arrives by email on the day it ships, and the courier usually takes one to three working days from there.
Is delivery ever free?
It is £7.95 for the whole order, not per item, and free once the goods reach £100 after any discount code; design or artwork charges are left out of that £100. 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. A mainland Highlands postcode puts a single £10 on the order.

Dim corners or people on the move call for one size bigger. Those distances follow the ISO 3864-1 distance-factor method (25 mm of height per metre) and sit alongside your risk assessment, not in place of it. 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 Danger 440 Volts Sign be printed in?

The picture is W012 from ISO 7010 (electricity), which gets the point across to visitors who read little or no English. Those colours and shapes come from the 1996 Safety Signs and Signals Regulations, which is why they look familiar.
How much does an A2 (420 × 594 mm) sign cost?
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.

Can a private person buy a single sign?

Before delivery, this sign costs from £5.02. On its opening option, Danger 440 Volts Sign leaves us after 6 working days on Saver.
We are kitting out a hall with several different signs. Can they all go in one order?

I need several signs, some in different sizes. How do I buy them?
Set up the first size, type how many you need next to Add to basket, then go back and set up the next size as another line.

I live in the Scottish Highlands. Will the Danger 440 Volts Sign cost more to send?

Can the wording on a Danger 440 Volts Sign be changed, or our logo added?
A school can add its crest to "Danger 440 Volts", a club its badge, a shop its name. Choose typesetting (£15) if you know the words, or design from your brief (£35) if you would like us to lay it out; each comes with one first draft and two rounds of changes. Have your own finished file? Upload it free and one of our team will look it over. Keep the symbol and safety colours unchanged so the sign still reads the right way. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all.
How many pixels does a photo need to print well on this sign?
Roughly 7,016 pixels across and 9,933 down for an A1 (594 × 841 mm) design, which is 300 dpi. Things read at arm's length need that 300 dpi at full size to stay crisp. Text and logos are safest as vector art, which never goes fuzzy. Pictures saved from a website or social media are nearly always too small, and our file check will point out any that could print blurred. Make the artwork for this sign the same size as the one you order, such as A4 (210 × 297 mm). For reference, Danger 440 Volts Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
I am not a designer. What if the file I send turns out to be unusable?
You will not be left guessing. Each uploaded file is opened and looked over by a member of the team, and problems such as low-resolution pictures, no bleed or the wrong page size are sent back to you to fix before printing. If fixing it sounds like a chore, choose typesetting for £15: we lay out your text and logo, show you a first draft, then make up to two rounds of changes. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On this page, Danger 440 Volts Sign starts from £5.02.
Will anyone look at my file before it is printed?
Every file gets a human check for size, bleed and resolution, and we contact you about any problem before printing. Nobody can know your details better than you, so double-check names, numbers and dates: we print what is supplied, and work begins once the order and file are confirmed. 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, Danger 440 Volts Sign starts from £5.02.
What thickness is the Danger 440 Volts Sign, and does it feel sturdy?
The sticker version, in self-adhesive vinyl, is only a film, so it sits flush on a door or wall. Every rigid option measures 3 mm. Foamex is a lightweight PVC foam board. Dibond has aluminium on both faces around a plastic middle, so it stays flat and firm but is easy to fix. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On this page, Danger 440 Volts Sign starts from £5.02.
Does the Danger 440 Volts Sign come in a peel-and-stick version?
Yes: self-adhesive vinyl is one of the material choices, and that version is simply a sticker with a backing to peel off. Use it on smooth things like glass, doors, cupboards, machines or painted plaster. Clean and dry the surface first, then smooth it on working out from the middle. If the wall is rough or dusty the sticker will not grip well, so go for one of the boards. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On its opening option, Danger 440 Volts Sign leaves us after 6 working days on Saver.
We are putting up a full set of signs at our premises. Which ones sit well next to this one?
Two good companions for it are Danger 6,600 Volts Sign and Danger High Voltage Keep Out Sign. Each has a page of its own with every size, material and a live price, and picking one material for all of them makes the wall look like a matching set. Put the lot in a single basket and you pay one delivery charge, which drops to nothing when the goods reach £100. You will also find this sign in our Electricians section.
Would the Danger 440 Volts Sign be useful for electricians?
For rewires, testing and inspections, look under Electricians in the shop: the Danger 440 Volts Sign is listed there. Prices begin at £5.02; 4 sizes are listed, starting at A4 (210 × 297 mm); the material choices are self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. People buying for that kind of work often add Danger High Voltage Sign or Taxi Magnetic Signs. Put everything in one order and delivery is free at £100 or more.
It gets dark early in winter. Can people still read the Danger 440 Volts Sign in the evening?
Only if a light falls on it. The Foamex, Dibond and vinyl sticker versions are printed without any reflective or glow-in-the-dark layer. So for a church car park, a school path or a yard used on winter evenings, put it beneath a lamp that is already there, or add a light. If your risk assessment says a sign has to reflect or glow, buy that one from a firm that makes them. 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. For reference, Danger 440 Volts Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
Will a Danger 440 Volts Sign cope with rain and wind outdoors?
"Danger 440 Volts" can go outside as long as you match the material to the job. For a sign that stays out for years, Dibond is the one to choose. Foamex will manage a sheltered spot, such as a porch or under a canopy, but it is really an indoor board. Strong sun slowly fades any print, so glance at outdoor signs every so often and swap any that have become hard to read. 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 Danger 440 Volts Sign?
It depends what "Danger 440 Volts" is going on. Brick or plaster: screws through holes near the corners, washers under the heads, and a light hand (Foamex especially). Painted doors and smooth walls inside: foam tape or sticky pads, no drilling needed. Fences and railings: two or four holes, then cable ties. Glass and glossy panels: the vinyl version, pressed on after a wipe and a dry. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
Which material is cheapest for the Danger 440 Volts 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. For reference, Danger 440 Volts Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
Do we legally have to display a Danger 440 Volts Sign?
Not in every case. The Health and Safety (Safety Signs and Signals) Regulations 1996 require employers to put up safety signs where a risk is left over once other controls are in place. So whether you need "Danger 440 Volts" on display, and where it goes, comes out of your own risk assessment. A sign adds to other safety measures and never takes their place. The symbol on this sign follows ISO 7010, reference W012.
Can I swap my file once I have paid?
It depends on timing. Until production begins, a new file can replace the old one, or the order can be cancelled with a full refund; once it has begun, nothing can be changed. Message us straight away on the Contact page with your order number. Items printed exactly as supplied or designed do not count as faulty, so check names, numbers and dates first. 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, Danger 440 Volts Sign leaves us after 6 working days on Saver.
Next year we will want the same sign again. Is reordering easy?
Yes. Treat it as a fresh order of the same item with the same settings, and attach the file you used last time. Keep a copy of the print file in a shared folder so whoever orders next year can find it. Change any details that have moved on, such as a new email address or this year's date, before uploading. 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, Danger 440 Volts Sign leaves us after 6 working days on Saver.
Can I send this sign back if I no longer need it?
Not for a change of mind. This sign is made for your order, and goods made to your specification fall outside the 14-day cancellation right (reg. 28(1)(b) of the Consumer Contracts Regulations 2013). You can still cancel and get all your money back before production begins. Anything faulty, damaged or wrong is covered by the Consumer Rights Act 2015, and we reprint it or refund you. Before delivery, this sign costs from £5.02. Nothing is printed ahead of time: each sign is made to order for you. For reference, Danger 440 Volts Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
Our treasurer needs a receipt for the accounts. What do we get?
Every order gets a confirmation email listing what was bought, the options chosen and the amount paid, and a club, school or small firm can file that as its record of payment. What you pay for this sign is the price shown on the page plus any delivery charge, nothing more. If your accounts need a particular kind of invoice, ask through the Contact page before you order and we will tell you what we can provide. 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 Danger 440 Volts 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?

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, Danger 440 Volts Sign starts from £5.02.
Can the Danger 440 Volts Sign carry wording in two languages, for example English and Welsh?
A community centre or a surgery often wants every visitor to understand a notice, and this sign can do that. Tick typesetting for £15, then give us your wording in each language, already translated, since translation is not something we do. You get one first draft and two rounds of changes. Keep the same symbol and sign colours so nobody misreads it. Sizes for this sign go from A4 (210 × 297 mm) at the small end to A1 (594 × 841 mm), 4 in all. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On this page, Danger 440 Volts Sign starts from £5.02.
Will my logo colours come out the same as on screen?
Very close, but not always identical. A screen glows, print reflects light, so a small difference is normal. Sending CMYK artwork keeps it nearest; RGB is changed to CMYK before printing and the brightest greens, blues and oranges can look a touch flatter. For an exact brand colour, give us the Pantone reference and we get as close as the material allows. 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, Danger 440 Volts Sign starts from £5.02.
I have never ordered printing before. Do I need to know the technical words?
No. A person on our team checks every file for size, bleed and resolution and tells you in plain words if anything needs changing. Or pick typesetting for £15 and we lay out your words and logo for you, with a first draft and two rounds of changes. 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, Danger 440 Volts Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
What if A1 (594 × 841 mm) is still too small for the Danger 440 Volts Sign?

Does a Danger 440 Volts Sign come upright or wide?

The spot gets full sun all afternoon. Could this sign warp in the heat?
It depends on the board. Foamex is foamed plastic, and a large, thin sheet in strong sun can curve, most of all when it is held only at the corners. Dibond sandwiches a core between aluminium skins and stays flat, which is why people choose it for signs that live outdoors for years. If you go with Foamex, fix it flat to a wall along its length or pick a thicker option. 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. For reference, Danger 440 Volts Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
Can I cut this sign down to size, or drill fixing holes, at home?
Foamex and Correx cut cleanly with a sharp craft knife run along a metal rule: score it a few times, then cut or snap along the line. Dibond is aluminium on both faces, so use a fine-tooth saw and take it slowly. Holes for screws or ties can be made with a normal drill bit at low speed; keep each hole 10 mm or more in from the edge. Trimming eats into the bleed area, so leave room in the design if you plan to trim anything off. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. For reference, Danger 440 Volts Sign is listed in 4 sizes, the smallest being A4 (210 × 297 mm).
Could the Danger 440 Volts Sign go on a door, say an office or classroom door?
It can, and the vinyl sticker version is the tidiest way to do it on a door or a glass panel. On a flat door, the 3mm Foamex board with foam tape on the back is a good alternative. Aim for eye height, either beside the door or on the side people push, so an open door does not hide it. Fire doors are different: ask the person responsible for the building before you drill into one. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
