Abrasive Wheel Awareness

23 August 2024

Abrasive wheels awareness is an extremely important aspect of an overall employee’s health and safety – where the employee is to use such tools. The abrasive wheel, if not properly used or maintained, is an extremely dangerous tool. The periphery of an abrasive wheel usually travels at a speed faster than a mile a minute. If a wheel should be broken while travelling at that speed, serious personal injury or damage to machinery or equipment might result. Unfortunately, serious injuries or fatalities are possible.

What is an Abrasive Wheel?

According to the Part 12 of the Safety, Health and Welfare at Work (General Application) (Amendment) Regulations 2016 (Regulations), an abrasive wheel can be:

wheel, cylinder, disc or cone which, whether or not any other material is comprised in it, consists of abrasive particles held together by mineral, metallic or organic bonds, whether natural or artificial,
a mounted wheel or point and a wheel or disc having (in either case) separate segments of abrasive material,
a wheel or disc made (in either case) of metal, wood, cloth, felt, rubber or paper and having any surface consisting wholly or partly of abrasive material, or
a wheel, disc or saw, to any surface of which is attached a rim or segments consisting of diamond abrasive particles,
which is, or is intended to be, power-driven, and is for use in any grinding or cutting operations.

Causes of Abrasive Wheel Accidents

Unfortunately, injuries or damage caused by use of abrasive wheels are in most cases not accidents at all. They are usually a result of carelessness or lack of knowledge in use of the tool. The most common causes are:

Using the wrong tool, or wheel for the job.
Careless handling, such as holding the tool and the material improperly, removing the guards, etc.
Improper mounting.
Incorrect speed of the disk and the tool.
Too much pressure applied.

The main dangers to an operator arise from pieces of the wheel or workpiece coming away, workers coming into contact with the wheel, and workers trapping their fingers between the wheel and the work rest.

Importance of Abrasive Wheel Awareness Training

Abrasive wheel awareness training is extremely important since the number of accidents and the circumstances in which they happen show that most can be avoided if workers know the risks and follow safety measures. The simple safety steps given below will help to prevent most accidents at grinding machines:

Step 1 – Inspection

When you receive a wheel, you should carefully inspect it, clean it with a soft brush and examine it for damage. In addition, you should carry out a ‘ring’ test as part of the examination. The ‘ring’ involves tapping the wheel with a non-metallic tool such as a screwdriver handle. If the wheel is safe to use a clear ring will be heard. But if the ring is ‘dead’ the wheel is cracked and you should not use it.

Step 2 – Storage

You should store wheels in a cool, dry area. Equally important is to provide suitable racks or bins and take precautions to prevent the wheels rolling or falling over.

Step 3 – Grinding Machines

All machines must be stable. Machines on benches should be bolted to the bench or securely fastened in some other way. A notice should be displayed on the machine showing the maximum speed of its spindle within each of its operating speeds. The operator should know how to start and stop the machine safely.

Step 4 – Choosing Wheels

The wheel must be suitable for the jobs in which it will be used. In general, soft wheels should be used on hard materials and hard wheels on soft materials. You should ask manufacturers for advice on which wheels to use. You should consider the following things when choosing the wheel:

The type of machine on which it will be fitted.
The speed of the machine or spindle – this must never be more than the maximum speed of the wheel.
The material to be used on the machine.
The finish needed.
The area of contact between the workpiece and the wheel.

Step 5 – Mounting the Wheel

The wheel must be mounted by someone who has been properly trained and appointed by their employer to do the work. The employer must keep a register of people who have been appointed to do this work. Abrasive wheels should only be mounted on the type of machine for which they were designed. It is essential that the speed of the spindle is not more than the maximum speed marked on the wheel.

Step 6 – Guarding

The wheel should be guarded so that only the area of the wheel needed for the work to be done is exposed. Guards should be fitted to contain the wheel parts if the wheel bursts and to prevent, as far as possible, the operator from coming into contact with the wheel.

Step 7 – Using Abrasive Wheels

Operators must be properly trained. In addition, operators should not wear loose clothing such as ties or jewellery. These items could become caught between the wheel and the workpiece. Furthermore, they should tie long hair back out of the way. Guards should always be in place. Equally important, eye protection should be worn for all dry grinding work, or transparent screens should be fitted to fixed machines to protect against sparks and particles. In addition, the floor space around the machine should be kept free of obstructions and slippery substances.

Obviously, the machine should only be used by one person at a time. It should be switched off always when not in use. To prevent the workpiece jamming between the work rest and the wheel, the work rest should be positioned as close as possible to the face of the wheel. It should be adjusted as the wheel wears. Lastly, the operator should hold the workpiece firmly and move it across the face of the wheel so that the wheel wears evenly. Clamps or similar devices can be used for small jobs.

Abrasive Wheels Awareness Training

The formal training in the safe use of abrasive wheels is required by law. There are no exemptions to this requirement. All personnel using any form of abrasive wheels must be trained in its proper use.

The Abrasive Wheels Awareness course developed by eLearn Safety is designed to supplement and provide additional training but not to replace formal training. It is the online part of a blended training program and students must also complete a practical session in order to be competent operators. Under the current legislation an employer must not allow any person to operate the wheel unless they are trained and competent to mount the wheel.

The Health and Safety Authority of Ireland (HSA) provides a wealth of relevant information via their website.

Online Health and Safety Training

Proactive Health and Safety training is critical to ensure a safe workplace. An effective training program can reduce the number of worker injuries and deaths. It can also reduce instances of property damage, legal liability, illnesses, and missed time from work.

Health and Safety training helps establish a culture in which employees themselves help promote proper safety procedures while on the job. It is important that new employees be properly trained and embrace the importance of workplace safety. The role of training in developing and maintaining effective hazard control activities is a proven and successful method of intervention.

This is why we have established Myelearnsafety school. We pride ourselves in how we guide, support and mentor our students. They receive support throughout their learning experience and into their working lives. Our staff have extensive training experience and also have many years industry experience. We understand the challenges that exist within Environmental and Occupational Health and Safety. Our priority is to ensure that all learners are fully prepared to differentiate themselves in the workplace after completing our Health and Safety courses.

Myelearnsafety offers fully online Health and Safety courses.
