Disc And Wheel Inspection

1. The disc type is correct for the material and task (grinding, cutting, flap disc, wire wheel)


Photo Comment

2. The disc maximum RPM rating meets or exceeds the no-load RPM of the grinder it is fitted to


Photo Comment

3. The disc is free from cracks, chips, notches, or delamination visible to the naked eye


Photo Comment

4. New discs are ring tested before fitting - tapped lightly and listened to for a clear tone, not a dull thud indicating an internal crack


Photo Comment

5. The disc diameter matches the guard and is within the size range specified for the grinder model


Photo Comment

6. The disc has not exceeded the manufacturer's specified shelf life or storage period


Photo Comment

7. Discs that have been dropped are inspected for damage or ring tested again before use


Photo Comment
Disc Fitting And Changing

1. The grinder is isolated from its power source before any disc change is carried out


Photo Comment

2. The disc has come to a complete stop before the guard is opened or the disc is removed


Photo Comment

3. The inner and outer flanges are clean, undamaged, and correctly sized for the disc being fitted


Photo Comment

4. The disc is fitted in the correct orientation as indicated by the manufacturer's markings


Photo Comment

5. The retaining nut is tightened using the correct spanner only - not improvised tools


Photo Comment

6. After fitting, the grinder is run briefly in a safe direction to confirm disc seating before use


Photo Comment
Work Area And Fire And Spark Controls

1. The workpiece is secured with clamps, a vise, or fixed support and will not move during grinding


Photo Comment

2. Flammable materials, liquids, and gases are removed or shielded from the spark zone


Photo Comment

3. Other workers and bystanders are positioned outside the spark and debris exclusion zone


Photo Comment

4. The spark and debris deflection direction is planned before grinding begins


Photo Comment

5. Fire suppression equipment is accessible in the work area where hot work is being conducted


Photo Comment

6. The grinding surface and surrounding area are checked for residual heat after operations cease


Photo Comment
Safe Operating Practices

1. The operator maintains a two-handed grip on the grinder body and auxiliary handle throughout operation


Photo Comment

2. The grinding disc is applied to the workpiece at the correct angle recommended by the manufacturer - typically 15 to 30 degrees for grinding


Photo Comment

3. Cutting discs are used only in a straight line and are not twisted, levered, or used for grinding


Photo Comment

4. Excessive pressure is not applied to the disc - the tool's weight and speed are allowed to do the work


Photo Comment

5. The operator's body is positioned to one side of the disc plane, not directly in line with the disc


Photo Comment

6. Loose clothing, jewelry, long hair, and beards are secured or covered before operation begins


Photo Comment

7. The grinder is not set down until the disc has come to a complete stop


Photo Comment

8. The grinder is not left running unattended at any point during operations


Photo Comment
PPE

1. Safety glasses and a full-face shield are both worn during all grinding and cutting operations


Photo Comment

2. Hearing protection rated for the noise level of the task is worn throughout operations


Photo Comment

3. Cut-resistant gloves appropriate to the grinding hazard are worn and do not impair tool grip


Photo Comment

4. Respiratory protection is available and worn where grinding generates hazardous dust or fumes


Photo Comment

5. Flame-resistant or spark-resistant clothing is worn where the volume of sparks warrants it


Photo Comment

6. Safety footwear is worn in all areas where angle grinder operations are taking place


Photo Comment
Disc Storage And Condition Management

1. Discs and wheels are stored in a clean, dry location away from moisture, solvents, and direct sunlight


Photo Comment

2. Discs are stored flat or on dedicated racks and are not stacked in ways that cause edge damage


Photo Comment

3. Discs with visible storage damage, impact marks, or contamination are removed from service


Photo Comment

4. The storage area stock is checked against manufacturer shelf life dates and out-of-date discs are disposed of


Photo Comment

5. Damaged or rejected discs are marked and disposed of so they cannot be retrieved and reused


Photo Comment
Periodic Inspection And Records

1. The grinder has a current, in-date inspection tag attached with the last and next inspection dates


Photo Comment

2. The electrical condition of the cord, plug, and insulation has been checked within the required inspection interval


Photo Comment
