Risks specific to the grinder
An angle grinder uses a high-speed accessory for cutting, grinding or other authorised operations. A jammed disc can cause a sudden reaction, alongside cutting and projectile risks. Sparks, dust, noise and vibration are also assessed. Risk changes with the material, accessory, posture and presence of other people.

Machine and disc compatibility
Intended use, diameter, mounting and permissible speed must match. A cutting disc must not be treated as capable of withstanding arbitrary side loads. Damage, storage condition and manufacturer requirements are checked before mounting. Removing the guard to fit a larger accessory removes a safety barrier and does not make the machine suitable for that work.
Preparing the workpiece and surroundings
The workpiece is secured so it cannot close the cut or move unexpectedly. A stable posture and the intended handles are maintained. Sparks and particles must be directed away from people and combustibles. Cutting used containers or unknown materials requires assessment of residues and composition; a clean-looking surface does not exclude other hazards.
Dust and personal protection
Extraction must suit the material and operation. Cutting mineral products may cause silica exposure; coatings also matter. Eye and face, hearing and respiratory protection are selected through assessment. Personal protective equipment supplements process control and does not justify working without a guard or with an unstable workpiece.
Repair example
A hypothetical operator needs to cut a section installed at an awkward height. Before starting, the team reviews whether it can be removed or another method used with stable support. The decision must not focus solely on having a powerful grinder. Tool reaction can turn a loss of control into a fall or serious injury.
Stopping and changing accessories
The tool must stop completely before being set down. Disc changes and maintenance require prevention of accidental startup appropriate to the equipment. Experience does not replace knowledge of the specific accessory. References explain technical principles; manufacturer instructions determine permitted operations and specific checks.
