Health and safety online course

Silica dust: cutting stone, concrete, brick and block

Silica dust training for everyone who cuts, grinds or drills stone and concrete

£22.50 a place, the whole price

This is PHW training with a certificate of completion. It is not an accredited qualification, so it is for you to decide whether it is enough for your business.

Each person does the course on their own phone, passes a test that is marked automatically, and gets a certificate with a QR code that anyone can scan to check. You see who has passed. £22.50 a place.

About 30 minutes on a phone, tablet or computer. Test marked by the system.

What gets asked for. HSE has said dry cutting of engineered stone is unacceptable, and that its inspectors will make more than 1,000 visits to fabricators across Great Britain over twelve months from May 2026. HSE's own guidance tells employers to train workers on the dust risks, how to use and check the controls, how to use and look after masks, and what to do if something goes wrong. Each certificate is the dated training record for one person.

Who it is for

  • Stone and worktop fabricators and fitters
  • Groundworkers and paving crews who cut kerbs, flags and blocks
  • Bricklayers and builders who cut block, brick and tile
  • Anyone who chases, cores, grinds or drills concrete and masonry
  • Labourers and other trades who work near that dust
What it covers
  • What silica dust does to the lungs, and why you cannot see it
  • Which materials and jobs give off silica, engineered stone included
  • What COSHH asks of the employer, and the order of control
  • Stopping or cutting down the dust before the work starts
  • Water suppression on a Stihl saw
  • On-tool extraction: the right class of unit, the hood, checks and testing
  • Masks: the right type, face fit testing, clean shaven, a fit check every time
  • Cleaning up, work clothing, health surveillance and the practical sign-off

How it works

  1. Buy places. Pay by card. Your order page is ready as soon as the payment goes through.
  2. Send the join link to your staff. One link covers everyone. Each person types their name and starts.
  3. They do the lessons on their own phone. It takes about 30 minutes in all, and they can stop and carry on later.
  4. They sit the test. It is marked by the system. Anyone who misses is told which lessons to read again. After a miss there is a wait before the next try, and after six tries in a row the lessons are read again.
  5. A pass gives a certificate. It has a QR code anyone can scan to check it, and your order page links to every one.
  6. You sign off the practical. Each certificate comes with a sign-off sheet. You watch the person do the job on your own equipment, tick each check and sign. The online course teaches the knowledge. You decide who is authorised to do the work.
The law behind it
  • Employers have to prevent exposure to hazardous substances such as silica dust or, where that is not reasonably practicable, adequately control it. Source: legislation.gov.uk
  • Employers have to give employees suitable and sufficient information, instruction and training. Source: legislation.gov.uk
  • The limit for fine silica dust (respirable crystalline silica) is 0.1 milligrams in each cubic metre of air, averaged over an 8-hour shift. Source: hse.gov.uk
  • Dust extraction equipment has to be thoroughly examined and tested at least every 14 months. Source: legislation.gov.uk
  • Where workers are regularly exposed to silica dust and silicosis may develop, health surveillance has to be provided. Source: hse.gov.uk
  • HSE says dry cutting of engineered stone is unacceptable. Its guidance on this is not a new law. HSE has said its inspectors will make more than 1,000 visits to fabricators across Great Britain over twelve months from May 2026. Source: press.hse.gov.uk

What you get

  • The online course for each place you buy: nine short lessons and a test
  • A certificate for each person who passes, with a QR code anyone can scan to check it
  • A page for you showing who has taken the course and who has passed
  • A sign-off sheet for you: things to watch each person do on your own saws, extraction and masks, then your signature to authorise them in writing.

£22.50 a place is the whole price. It costs the same for one place or fifty.

The dust you cannot see

Cut, grind or drill concrete, stone, brick or block and you make dust. Some of it you can see. It settles on your jacket and your tools. The part that does the damage you cannot see.

HSE calls it respirable crystalline silica. It is fine enough to get deep into your lungs and too fine to see in normal light.

What it does to you

  • Silicosis: the lung tissue scars and hardens, and you lose lung function.
  • COPD: a lung disease that leaves you short of breath, coughing, and disabled for good.
  • Lung cancer: HSE says heavy and prolonged exposure can cause it.

Silicosis cannot be undone, and HSE says it carries on getting worse even after you stop being exposed. At the start there are often no symptoms. Shortness of breath comes later.

HSE says silicosis usually develops after at least ten years of exposure. Very high exposure can make people ill much faster.

The limit

The workplace exposure limit is 0.1 milligrams of this dust in each cubic metre of air (written 0.1 mg/m3), averaged over an eight hour day. That is a tiny amount. HSE says it is the most you should breathe in a day, even with the right controls in place.

There is good news. HSE says the risk from silica is almost entirely preventable when the dust is properly controlled. That is what the rest of this course is about.

You cannot judge silica by eye. Control the dust at the tool, every time.
Practice question

You cut a slab and see no dust in the air. What does that tell you?

Questions

How long does it take?

About half an hour on a phone. It is nine short lessons, each with one question, then a test of 15 questions. People can do a lesson in a tea break and carry on later.

What is the certificate?

It says the person completed the online silica dust course and passed the test. It lists what the course covered and carries a QR code and a certificate number. It is training evidence you can put on file and show to anyone who asks.

How does the practical part work?

Once someone has passed, you watch them set up and work with your own saws, extraction units and masks, and tick off the checks on the practical sign-off sheet. When every check is ticked, you sign to authorise them in writing for that work. The online course teaches what the dust does and how to control it. The practical on your own equipment is assessed and authorised by you.

Does the course include the face fit test?

The course explains what a face fit test is and why each person needs one on the mask they will wear. The test itself is done on the person, with that mask. The practical sign-off sheet has a line to check it has been done.

Can staff do it on a phone?

Yes. The course and the test are made for a phone screen, and each person uses their own phone.

How can anyone check a certificate?

Scan the QR code on it. It opens a page that confirms the certificate is genuine and shows what it says.

What if someone fails the test?

They are told which lessons to re-read, and they can sit the test again with a fresh set of questions. There is no limit on retakes.

How long does the certificate last?

It carries the date the person passed. You decide when to retrain people, and you can buy places again whenever you like.

Where does the course content come from?

It is drawn from the COSHH Regulations 2002 and published HSE guidance. Contains public sector information published by the Health and Safety Executive and licensed under the Open Government Licence v3.0.

What if someone loses their link?

They can ask for it again by email on the "Lost my link" page, as long as they gave an email address when they started.
