Question 2

Identify mechanical hazards associated with bench top grinder

Answer 2

Entanglement

Friction

Abrasion

Ejection of material

Flying particles

Drawing in

Question 3

Outline precautions for use of bench top grinders

Answer 3

The wheel should be enclosed as much as possible in a strong casing, which should be capable of containing a burst wheel. To prevent movemnt the grinder should be securley bolted down. The adjustable tool rest should be adusted as close to the wheel as possible, the adustable screen should be fitted over the wheel to protect the operators eye and sutable PPE should be worn. Only trained and competent people should mount the abrasive wheel. Maximum speed should be marked on the machine so wheels can be matched and the machine should undergo regukar maintenance, testing and inspection.
