Abrasive Wheel Awareness

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.

Understanding People in the Workplace Environment

Understanding people in the workplace environment is essential if we are to achieve a safe workplace. In reality, accidents in the workplace are ‘people’ problems. At some point in any work-related situation, immediate or distant, people and decisions were involved. Undoubtedly, it is the task of modern safety management systems to recognise that fact. Consequently, the opportunities for mistakes and the harm that can arise when they are made should be minimised.

To err is human. We all make mistakes. Awareness of our limitations is needed before we can set up systems successfully which take those limitations into account and maximise safety efforts in any workplace.

Behavioural factors

Understanding behavioural factors, or as often referred to as ‘human factors’ are essential in understanding people in the workplace environment. These factors which may affect human performance include:

Perceptual, mental and physical capabilities of people.
Interaction of people with their organisations, jobs and working environment.
Influence of equipment and systems design on human performance.
Organisational characteristics which influence safety-related behaviour.
Social and inherited characteristics of people.

Modern techniques of managing safety and health incorporate best practice within them so as to produce and influence a positive safety culture.

Promotion of a Positive Safety Culture

Promoting and fostering positive attitudes to safety and health can be done by:

Effective communication. Passing information to and from, and regular consultation with the employees.
Achieving a positive commitment to safety by senior management that is both real and visible.
Maintaining good training standards.
Maintaining good working environments with a high potential for safe working conditions to be achieved.

All these can be, and must be, found within organisations committed to a high standard of excellence in safety and health at work.

Maintaining Good Training Standards

Training for health and safety is not an end in itself, rather, it is a means to an end. With this in mind, a few conditions need to be present for any safety training to be successful:

The active commitment, support and interest of management,
Necessary finance and organisation to provide the opportunity for learning to take place, and
The availability of suitable expertise in the subject.

eLearn Safety is a training organisation which provides high quality online, blended and face-to-face safety training courses. To this end, eLearn Safety program development and delivery is driven by customer service values where the learner is able to engage in the learning process however and wherever they want. In addition, all eLearn Safety staff are highly trained and receive ongoing CPD. A number of fully online Occupational and Environmental Health and Safety courses is available through eLearn Safety courses website page.

Safety is not just for the workplace. Safety is part of everyday life; from first aid to food safety, these skills improve the quality of life not only in the workplace but at home and in the community.

In addition to eLearn Safety courses, there is a number of available workplace safety information available online. For example, the Health and Safety Authority (HSA) provides a wealth of information about the topic via their Workplace Health website page. Additionally, Citizens Information offers a number of relevant information via their website page Health and safety at work.

Understanding People in the Workplace Environment – Why does it Matter?

The main health and safety regulations in Ireland are the Safety, Health and Welfare at Work Act 2005 and Safety, Health and welfare at Work (General Application) Regulations 2007. The Act 2005 applies to employers, employees and the self-employed. Indeed, this is done in the interest of securing a preventive approach to occupational health and safety. In addition, the GA Regulations 2007 outline the specific workplace safety matters.

Many specific pieces of health and safety legislation contain requirements to provide training for employees engaged in certain tasks. However, it should be noted that there is a general duty placed on employers to ensure that all employees are trained and provided with information, instruction and supervision as necessary to ensure their health and safety so far as is reasonably practicable.

The support of management demonstrates the presence of the environment into which the trained person can return and exercise new skills and knowledge. The management team also demonstrates support by setting good examples. Workers are most likely to stop obeying safety rules if supervisors and managers are known to ignore them.

Dangers of Vibration at Work

Use of plant and equipment that produces vibration is often not considered as a serious risk and dangers of vibration at work are often overlooked.

Vibration is the transmission of force from work processes into the worker. The Health and Safety Authority of Ireland (HSA) defines vibrations as ‘rapid movement to and fro or oscillating movement‘.

Examples of Vibration at Work

People in the course of their work life may be exposed to many sources of vibration. Dangers of vibration at work are more often overlooked than not. Some vibration affects the whole body (WBV), e.g. when driving a dumper truck over rough and even ground. Here the vibration, in the form of large shocks or jolts, is transmitted to the whole body via their feet or the seat. This could cause injury to the lower back and spine.

The most common problem is Hand Arm Vibration (HAV). HAV is caused by exposure to vibration, e.g. from using hand power tools. This can be very disabling, causing severe pain in hands and arms and lack of hand movement and feeling in the fingers. It is preventable but permanent once the damage is done.

Dangers of Vibration at Work – HAV Symptoms

The most common HAV symptoms to look for are:

Tingling in the fingers.
Loss of feeling and sensation in the fingers.
Reduced strength in the hand.
Fingers that go white in the cold and then red and painful on recovery.

Dangers of Vibration at Work – HAV Controls

Dangers of vibration at work, i.e. risk from vibrating tools or machines can be minimised by:

Introducing methods that eliminate, substitute or reduce the exposure to vibration.
Avoiding prolonged or frequent use of vibrating equipment.
Keeping cutting tools sharp so they remain efficient.
Making sure equipment is well maintained.
Avoiding forcing or gripping the tool more than is necessary.
Wearing gloves to protect the hands.
Exercising and massaging the fingers during breaks to restore circulation.

Health surveillance is crucial to spot and respond to early signs of damage.

Dangers of Vibration at Work – Further Reading

Chapter 2 of Part 5 and Schedule 6 to the Safety, Health and Welfare at Work (General Application) Regulations 2007 (S.I. No. 299 of 2007) as amended by the Safety, Health and Welfare at Work (General Application) (Amended) Regulations 2007 (S.I. No. 732 of 2007) sets down the minimum requirements for the protection of workers from the health risks associated with vibration in the workplace. This is a legislation that looks into dangers of vibration at work.

The Health and Safety Authority of Ireland (HSA) on their webpage Vibration at Work provide relevant to vibration at work information.
