NPORS N301

NPORS Abrasive Wheels Training (N301)

An abrasive wheel that bursts sends pieces across a workshop at the speed it was spinning. The law that used to govern it was repealed and the duty now sits in PUWER regulation 9, which says nobody uses one unless they have been trained. Half a day on selection, inspection, mounting and the guard.

What makes our N301 Abrasive Wheels different

Speed, guard, mountingThe three things that make a wheel safe or lethal. Maximum operating speed against the machine, a guard that is there and correctly set, and a wheel mounted with the right flanges and blotters.
Inspection before it goes onDamaged wheels do not announce themselves. Handling, storage, visual inspection and the ring test for the wheels where it applies.
Half a day, six peopleShort enough to run two groups in a visit, which is how most sites get a whole workforce trained without losing a day of production.
On your own machinesAngle grinders, bench grinders, cut off wheels, diamond blades. Your machines, your wheels and your material.

About this course

The NPORS N301 Abrasive Wheels category covers the selection, inspection, mounting and safe use of abrasive wheels on angle grinders, bench and pedestal grinders and cutting machines. It is the general abrasive wheels course: the one that suits fabricators, fitters, maintenance staff, groundworkers and anybody who picks up a grinder. The separate N017 category covers the hand held petrol driven cut off saw specifically, and many crews need both.

The reason abrasive wheels have their own training requirement is the way they fail. A wheel runs at very high speed and stores a great deal of energy. If it is the wrong wheel for the machine, if it is run above its maximum operating speed, if it has been dropped, chipped or stored badly, or if it is mounted with the wrong flanges or without blotters, it can burst, and the pieces travel. The other injuries come from contact with a running wheel, from a machine without a guard, and from kickback when a cutting disc binds in the cut.

The Abrasive Wheels Regulations 1970 were repealed and the duties now sit within PUWER 1998, with HSE guidance in HSG17 covering wheel characteristics, training, mounting, guards, portable and hand held grinders and the protective equipment that goes with them. Regulation 9 of PUWER requires adequate training for anybody using work equipment, and abrasive wheels are the classic case. Half a day covers wheel types and markings, checking the maximum operating speed against the machine, handling and storage, inspection including the ring test where it applies, mounting with the correct flanges and blotters, guard setting, and cutting and grinding technique.

  • Wheel types, markings and matching: bonded abrasive wheels, cutting and grinding discs and diamond blades, reading the maximum operating speed and dimensions from the wheel, and the rule that machine speed must never exceed the wheel's maximum operating speed
  • Handling, transport and storage of wheels, and the damage that makes a wheel unfit for use
  • Inspection before mounting, including visual inspection and the ring test for the wheels where that test applies
  • Mounting: spindle, flanges, blotters, tightening, running up and standing out of the plane of the wheel while it runs up to speed
  • Guards and their setting, kickback when a cutting disc binds, and correct working position
  • Dust, sparks, hot work, noise, vibration and PPE, and the duties under the Health and Safety at Work etc. Act 1974 and PUWER 1998 regulation 9

How completing this course helps you

  • The NPORS N301 Abrasive Wheels category, registered with NPORS and recognised nationally
  • An NPORS Red Trained Operator card, or a Blue Competent Operator card where you hold the relevant NVQ, carrying the CSCS logo while your CITB Health, Safety and Environment test is in date
  • People who check the wheel's maximum operating speed against the machine before they fit it
  • Evidence of the training PUWER regulation 9 requires for anybody using an abrasive wheel

Who should attend?

Fabrication and welding shops, plant and vehicle fitters, maintenance and facilities teams, groundworkers and civils crews, demolition and refurbishment contractors, joiners and shopfitters, highways and utilities teams, and anybody in a yard or workshop who changes wheels on a bench grinder. Because it is half a day for six people, it is one of the easiest categories to put a whole workforce through.

Entry requirements. You should be at least eighteen, able to handle and control a powered machine, and able to follow spoken and written English well enough for the theory test, though an interpreter or a reader can be arranged on request. No prior card is required. Tell us at enquiry what machines and wheels your people use, because the practical is built around them. For the version of the card that carries the CSCS logo you need a CITB Health, Safety and Environment test pass at Operatives level taken within the last two years, which we book for you.

Course content

What you will cover

Half a day split between the classroom, covering wheel types, speeds, inspection and the duties, and hands on wheel changing and cutting or grinding with the guard set correctly.

Theory

Wheels, speeds and duties

  • Health and Safety at Work etc. Act 1974 and PUWER 1998, including the regulation 9 training duty and the repeal of the Abrasive Wheels Regulations 1970
  • HSE guidance HSG17 and what it says about wheel characteristics, training, mounting, guards and portable grinders
  • Wheel and disc types, bonded abrasives, cutting discs, grinding discs and diamond blades
  • Wheel markings, dimensions and maximum operating speed, and matching them to the machine
  • Handling, transport and storage, and the damage that takes a wheel out of use
  • Inspection and the ring test, and where the ring test does and does not apply
  • Mounting: spindles, flanges, blotters, tightening and the correct run up procedure
  • Guards, kickback, working position, sparks and hot work, dust, noise and PPE
Practical

On the machine

  • Selecting the right wheel for the machine, the material and the task
  • Inspecting a wheel before use and rejecting a damaged one
  • Isolating the machine, removing the old wheel and fitting the new one with the correct flanges and blotters
  • Setting the guard correctly and checking it before starting
  • Running the machine up to speed while standing out of the plane of the wheel
  • Cutting or grinding with correct stance, grip and working position
  • Shutting down, isolating, storing wheels correctly and leaving the area safe

Method of assessment

How the N301 abrasive wheels test works

NPORS assess the category by theory test and practical test. The practical covers wheel selection, inspection and mounting as well as using the machine, because the mounting is where most of the risk sits.

1

1. Enquiry and group

Tell us how many people, where, and what machines and wheels they use. Six sit with one instructor, and because the course is half a day we can often run two groups in the same visit. We quote per group.

2

2. Pre course check

We confirm what machines will be used, agree whether you need the CSCS logo version of the card, book the CITB test where it applies, and take the details NPORS need.

3

3. Training

Classroom on wheels, speeds, inspection and the duties, then hands on wheel changing and cutting or grinding with the guard set.

4

4. Theory test

The NPORS theory test covering legislation and the training duty, wheel types and markings, speeds, storage, inspection, mounting, guarding and PPE.

5

5. Practical test

You select and inspect a wheel, isolate the machine and mount the wheel correctly, set the guard, run up safely and cut or grind with correct technique, assessed against the NPORS test specification.

6

6. Registration and card

We register the pass with NPORS and apply for your card, carrying the CSCS logo where you hold a current CITB Health, Safety and Environment test.

After the course

Two abrasive wheels categories, and they are not the same

NPORS run two abrasive wheels categories and they cover different machines. N301 is the general one, aimed at angle grinders, bench and pedestal grinders and the wheel changing that goes with them. N017 covers the hand held petrol driven cut off saw, the machine that gets used on kerbs, slabs, paving and steel on groundworks and highways jobs. They share the same theory about wheel speeds, mounting and guarding, but the machines behave completely differently in the hand and are assessed separately. Crews that use both need both, and it is usually sensible to run them together.

The other thing worth fixing after the course is storage. A large proportion of damaged wheels get damaged in the van, in the bottom of a tool box or on a shelf where something heavy was put on top of them. Racking wheels properly, keeping them dry and taking chipped ones out of circulation costs almost nothing and removes the most common cause of a wheel failing in use.

  • N017 Abrasive Wheels Hand Held Cut Off Saw for the petrol disc saw on groundworks and highways jobs
  • N302 Bench Saw and N303 Circular Saw where the same crews also cut timber
  • N048 Powered Hand Held Breaker for breaking out after the cuts are made
  • CITB Health, Safety and Environment test booked with us where the CSCS logo version of the card is needed

Who is coming, and how many

We do not run these to a timetable. The course is built around your people: how experienced they are and how many of them there are, which is what sets the length and the cost. Pick the mix and we will come back with a date and a price.

The course builder needs JavaScript. Without it, tell us how many people and what experience they have and we will price it up.

N301 Abrasive Wheels FAQs

N301 is the general abrasive wheels category, aimed at angle grinders, bench and pedestal grinders and wheel changing. N017 is Abrasive Wheels Hand Held Cut Off Saw, which covers the petrol driven disc saw used on kerbs, slabs, paving and steel. The theory overlaps but the machines are different and they are assessed separately. Crews that use both need both.

No. The Abrasive Wheels Regulations 1970 were repealed and the duties now sit within the Provision and Use of Work Equipment Regulations 1998, with HSE guidance in HSG17. Regulation 9 of PUWER requires adequate training for anybody using work equipment, which is where the training duty for abrasive wheels comes from.

The NPORS test sheet we work from gives a half day novice duration with six candidates and one instructor. Because it is half a day, two groups can often be run in one visit, which is how most employers card a whole workforce efficiently. We confirm the arrangement when we quote.

Not on the NPORS test sheet we work from. N301 shows a novice course and a refresher, each with a maximum of six tests, and no experienced worker figure.

Yes, and that is the most important part. Selecting the right wheel, checking its maximum operating speed against the machine, inspecting it, and mounting it with the correct flanges and blotters. Most abrasive wheel failures are set up before the machine is ever switched on.

A check for cracks in certain bonded wheels, carried out by suspending the wheel and tapping it lightly to listen for a clear ring rather than a dull note. The course covers how to do it and, just as importantly, which wheels it applies to, because it is not a universal test.

Usually yes. Six candidates per group and half a day each means a morning group and an afternoon group is a normal arrangement, and it keeps most of your workforce on the job for most of the day.

An NPORS Red Trained Operator card, or a Blue Competent Operator card where the holder has the relevant NVQ. Either carries the CSCS logo while a CITB Health, Safety and Environment test pass is in date.

NPORS courses are priced per course, not per person. What you are paying for is the instructor, the registered tester and the machine time, so the figure turns on four things: the category, which route your operators need (novice, experienced, conversion or refresher), how many people are coming, and whether we run it on your site or at one of ours. It is also why a squad works out considerably cheaper per head than sending operators out one at a time. Use the course builder on this page: tell it who is coming and it works out how many days the course takes and how many times it has to run, which is what the price is built from. Then ask us and you will get a figure for that exact group rather than a list price with conditions attached.

We run NPORS courses across the UK rather than out of one fixed centre, and for most categories the better answer is that we come to you: your operators are assessed on the machine they will be using anyway, nobody loses a day travelling, and for a group it costs less. If you would rather come to us, we have centres at Trent House in Stoke, Pride Park in Derby, Europa House in Manchester and Kingsway House in Liverpool. Tell us where the work is and we will say honestly which way round makes more sense.

There is no fixed timetable to wait for. NPORS courses here are run to order, which means the dates are built around your programme rather than ours, and a single operator or a full squad can normally be booked in within a couple of weeks. If you have a card about to expire or a start date to hit, say so when you enquire and we will work to it.
