General Safety Guidelines while Working on Grinding Machines:

1. Grinding wheels badly worn or cracked should be replaced.
2. The grinding wheel should be properly balanced while mounting.
3. One should ensure that no combustible or flammable materials are nearby that could be ignited by sparks generated by grinding wheels during grinding operations.
4. One should allow the grinding wheel to reach full speed before stepping it into the grinding position. Faulty wheels usually break at the start of an operation.
5. Always use the face of the grinding wheel that is meant for grinding.
6. One should slowly move job-pieces across the face of wheel in a uniform manner. This will keep the wheel sound.
7. Grinding wheels should be checked properly timely for soundness. Suspend the wheel on a string and tap it. If the wheel rings, it is probably sound.
8. One should not use a grinding wheel that has been dropped or dealt with a heavy blow, even if there is no apparent damage.
9. Before using a new grinding wheel, let it run for a few seconds at the full speed to check and make sure that it is perfectly balanced.
11. One should not operate the grinding wheel beyond its bursting speed.
12. Follow the manufacturer's instructions for the correct use of the grinding wheels.
13. Always wear goggles during grinding or allied processes.

Safety Precautions while Working on Lathe Machine

1. One should always be sure that all guards are in place before running the machine.
2. Always clamp the work and tool properly with correct size of work and tool holding device.
3. Always keep the machine clear of tools.
4. Machine should be stopped before making measurements or adjustments.
5. Wear an apron or a properly fitted shop coat. Goggles should also be used.
6. One should remove necktie, wrist watch and jewellery while working.
7. One should not operate the lathe until he knows the proper procedure.
8. One should check the work frequently when it is being machined.
9. One should check the face-plate or chuck by hand to be sure that there is no danger of the work striking any part of the lathe.
10. Stop the machine and remove chips with pliers. One should not remove the chips by hand.
