Abrasive Wheels Training Certificate PPE and Risk Assessment

Question 1

What is the minimum standard of eye protection required when using an abrasive wheel?

Accepted Answer

Safety spectacles conforming to BS EN 166 with appropriate impact rating

Answer

Safety spectacles or goggles conforming to BS EN 166 with an appropriate impact rating are the minimum eye protection required. For operations generating significant debris, full-face visors may be necessary. A wheel guard does not eliminate the need for eye protection.

Question 2

In a risk assessment for abrasive wheel operations, which of the following is NOT typically identified as a hazard?

Accepted Answer

The colour of the workshop walls

Answer

The colour of workshop walls is not a hazard associated with abrasive wheel operations. Genuine hazards include wheel burst, entanglement, dust exposure, noise, vibration, eye injuries from flying particles, and contact with the rotating wheel.

Question 3

Under the Personal Protective Equipment at Work Regulations 1992 (as amended 2022), who is responsible for providing PPE for abrasive wheel operations?

Accepted Answer

The employer must provide suitable PPE free of charge

Answer

Under the PPE at Work Regulations, employers must provide suitable PPE free of charge to employees who may be exposed to risks that cannot be adequately controlled by other means. Since 2022, this also applies to limb (b) workers (those previously classed as self-employed).

Question 4

When conducting a COSHH assessment for abrasive wheel operations, which exposure should be specifically assessed?

Accepted Answer

Exposure to respirable dust including possible silica content

Answer

Grinding operations can generate respirable dust that may contain crystalline silica (from certain wheel types and workpiece materials), metal particles, and abrasive fragments. The COSHH assessment must identify these exposures and implement appropriate controls including LEV and RPE.

Question 5

Why should gloves generally NOT be worn when operating a bench grinder or pedestal grinder?

Accepted Answer

Gloves can be caught by the rotating wheel, dragging the hand into the wheel

Answer

Gloves should generally not be worn when using bench or pedestal grinders because they can be caught by the rotating wheel, pulling the operator's hand into contact with the abrasive surface. This is an entanglement hazard. However, gloves may be appropriate for hand-held angle grinder operations.
