Abrasive wheels training in Ireland: duties for employers and wheel mounters

Irish workplace rules distinguish between using an abrasive wheel safely and being authorised to mount one. Employers must ensure wheels are suitable, properly mounted and used within safe speed limits, with guards where required. An employee may mount a wheel only if the employer has authorised that person for the wheel or class of wheels, following specified training and instruction and a check of competence. A course completion record on its own is not the employer's authorisation.

Which rules apply?

The Safety, Health and Welfare at Work (General Application) (Amendment) Regulations 2016 inserted Part 12, “Abrasive Wheels”, into the General Application Regulations. Part 12 applies to employers responsible for abrasive wheels used for grinding or cutting at a place of work. Its definition covers more than a traditional bench grinder wheel: it includes certain discs, cones, mounted points and diamond-abrasive wheels used in powered cutting or grinding.

The rules address suitability, speed, mounting, authorisation, training, guarding and rests. The Health and Safety Authority (HSA) explains that the 2016 provisions replaced the older 1982 abrasive wheels rules. Employers should base procedures on the current Part 12 and on the wheel and machine involved, rather than relying on an old course title or a general statement that “abrasive wheels training” has been done.

The special rule for mounting wheels

Regulation 213 says an employer must not allow an employee to mount an abrasive wheel unless the employee is authorised by that employer for the wheel or class of wheels. Before authorising, the employer must ensure the employee has been trained and instructed in accordance with Schedule 14 and is competent to mount the wheel. There is a specific exception for an employee undergoing mounting training while working under the immediate supervision of an authorised employee.

This is more precise than saying that every person who uses a grinder must hold a mounting certificate. The express authorisation rule concerns mounting. Operators still need the information, instruction and training necessary to use equipment safely under the wider 2005 Act duties and the employer's risk assessment. If a worker both operates the machine and changes wheels, the mounting authorisation requirement applies to that part of the job.

What must mounting training cover?

Schedule 14 sets out subjects for each wheel or class of wheels covered by the proposed authorisation. They include proper mounting methods, hazards and precautions, wheel markings and speed information, safe storage and handling, inspection and testing for damage, the functions and assembly of components such as flanges and washers, balancing, dressing, adjustment of rests and use of relevant guidance. Training also needs to cover Part 12 of the regulations.

The employer should check that the employee can apply this knowledge to the actual wheels and machines used. A person familiar with one wheel class is not automatically authorised for every other class. The authorisation should identify its scope. Regulation 213 requires details of each authorisation, including the wheel or class, to be entered in the employer's Safety Statement. The employer may revoke an authorisation and must update the statement if it does.

Speed, condition and guarding

Regulation 210 requires the wheel to be suitable for the work, having regard to injury risk. Regulation 211 deals with maximum permissible wheel speed, markings and spindle speed. Employers must not operate a wheel above the appropriate manufacturer-specified maximum speed, subject to the regulation's stated exceptions. Machine and wheel information therefore has to be checked together when selecting or replacing a wheel.

Regulation 212 requires proper mounting. Regulation 214 requires a guard to be provided and kept in position at a moving abrasive wheel unless a specified impracticability applies, and sets requirements for guard design and maintenance. It also addresses workpiece rests and protective flanges where needed. Some wheel types and uses have stated exceptions, so employers should read the relevant provisions rather than assume every machine has identical guarding rules.

What an employer should put in place

Identify each powered cutting or grinding task and the wheels used. Assess the risks and choose equipment suitable for the work. Make sure users understand the machine's controls, the wheel's intended use and speed limits, guarding, safe handling and what to do if a wheel is damaged. Keep instructions and supervision proportionate to the risks. Only employees who meet Schedule 14 training and competence requirements should be authorised to mount wheels, and the authorisation should be recorded in the Safety Statement.

Check practices when new machines, wheel types or processes are introduced. A change may call for further instruction or a new authorisation scope. The employer's duty is to maintain a safe system for actual work, not simply collect course certificates. Wheel selection, competent mounting, condition checks and guarding must all work together.
