Abrasive Wheels Training Certificate UK Legal Framework for Abrasive Wheels 2 — Questions and Answers
Question 1: What is the employer's duty under the Control of Noise at Work Regulations 2005 for angle grinder operators?
- Assess noise levels, implement engineering controls to reduce noise at source, provide hearing protection when levels exceed 85 dB(A), designate hearing protection zones, and provide health surveillance for regularly exposed workers (Correct answer)
- Simply provide hearing protection to any worker who requests it
- The daily exposure limit applies only after 5 years of employment
- Noise regulations only apply to fixed machinery in factories — not portable tools
Correct answer: Assess noise levels, implement engineering controls to reduce noise at source, provide hearing protection when levels exceed 85 dB(A), designate hearing protection zones, and provide health surveillance for regularly exposed workers
The Control of Noise at Work Regulations 2005 require: noise assessment, engineering noise reduction where reasonably practicable, hearing protection provision above 85 dB(A) (mandatory at or above the upper EAV), designation of hearing protection zones, audiometric health surveillance for workers regularly exposed above the upper EAV, and health records.
Question 2: What does the Control of Vibration at Work Regulations 2005 require when a worker's vibration exposure approaches the ELV?
- The employer must take immediate action to reduce exposure below the ELV, as the ELV is the maximum permitted daily exposure that must not be exceeded (Correct answer)
- The ELV is advisory and may be exceeded with medical supervision
- Only health surveillance is required at the ELV — no operational changes are needed
- The ELV only applies if the worker has reported symptoms
Correct answer: The employer must take immediate action to reduce exposure below the ELV, as the ELV is the maximum permitted daily exposure that must not be exceeded
The ELV of 5 m/s² A(8) is an absolute legal limit that must not be exceeded. The employer must identify the cause, implement technical and organisational controls to reduce vibration exposure, and provide health surveillance. Common controls include: anti-vibration tools, job rotation, and restricting daily exposure time.
Question 3: What records must be kept under PUWER 1998 for abrasive wheel training?
- A record of each trained employee's name, training date, training content, trainer name, and any assessment outcome (Correct answer)
- Only a signed attendance register with no content details
- No formal records are required — PUWER states training must be 'adequate' but does not specify record format
- Records only for employees who mount wheels — users' training need not be recorded
Correct answer: A record of each trained employee's name, training date, training content, trainer name, and any assessment outcome
PUWER does not prescribe a specific record format but best practice and enforcement expectations require records to demonstrate: who was trained, when they were trained, what the training covered, who provided it, and (for appointed mounters) the outcome of any competence assessment. Records must be available for HSE inspection.
Question 4: What is the legal significance of CE/UKCA marking on an abrasive wheel product?
- It confirms the product conforms to the essential health and safety requirements of the relevant supply regulations, including maximum speed testing and specification marking (Correct answer)
- CE/UKCA marking on a wheel means any speed is acceptable as it has been safety-tested
- CE/UKCA marking replaces the need for a ring test before use
- Only wheels imported from outside the UK require CE/UKCA marking
Correct answer: It confirms the product conforms to the essential health and safety requirements of the relevant supply regulations, including maximum speed testing and specification marking
CE marking (and UKCA marking post-Brexit for UK market) indicates the product meets the essential health and safety requirements of the relevant EU/UK supply regulation (e.g., machinery directive / UK machinery regulations). For abrasive wheels, this includes testing to EN 12413, correct speed and specification marking, and documentation. It is a legal requirement for market placement, not a guarantee of suitability for every application.
Question 5: What specific legal requirement does PUWER 1998 impose on the spindle speed marking of abrasive wheel machines?
- The machine must be marked with its maximum no-load spindle speed, and this must be readily visible to the operator, to enable wheel speed compatibility checks (Correct answer)
- Speed marking is only required on machines above 2kW power rating
- Speed marking is required only when the machine is used for high-risk applications
- Manufacturers are encouraged but not legally required to mark spindle speed
Correct answer: The machine must be marked with its maximum no-load spindle speed, and this must be readily visible to the operator, to enable wheel speed compatibility checks
PUWER requires that the maximum spindle speed is marked on the machine so the operator can compare it against the wheel's maximum RPM before mounting. Without this information, the critical speed compatibility check cannot be performed. Speed marking is a legal requirement, not an optional recommendation.
Question 6: Under RIDDOR 2013, what type of injury from an angle grinder would require immediate reporting to the HSE?
- Any amputation of a limb, finger, or thumb (a specified injury), or any fracture other than to a finger, thumb, or toe (Correct answer)
- Only fatalities — other injuries can be reported within 15 days
- Only injuries requiring hospital admission of more than 3 days
- Any cut requiring first aid treatment
Correct answer: Any amputation of a limb, finger, or thumb (a specified injury), or any fracture other than to a finger, thumb, or toe
RIDDOR 2013 requires immediate reporting of 'specified injuries' which include: fractures (excluding fingers, thumbs, toes), amputations, any injury likely to lead to permanent loss of sight, crushing injuries to the head or torso, and others. Angle grinder amputations and serious lacerations frequently fall into specified injury categories requiring immediate reporting.
