REQUIREMENTS FOR SAFE ABRASIVE STOCK REMOVAL
A) SAFETY GLASSES MUST BE WORN AT ALL TIMES WHEN WORKING WITH ABRASIVE STOCK REMOVAL EQUIPMENT! Failure to comply may result in revocation of shop privileges. These tools are prone to catastrophic failure. When they fail, material is thrown from the machine at high velocity.
B) Know how to stop the sander or grinder under all conditions before you attempt to start the machines.
C) WARNING!! Loose clothing, long hair, personal stereo wires and jewelry may become entangled in rotating equipment leading to serious injury or death! Make certain that such articles are removed or securely fastened to avoid entanglement.
D) WARNING!! Abrasive machines remove material at an incredibly rapid rate. You must pay extreme attention to what you are doing! If your hand comes into contact with the media, you WILL get cut severely! It is not uncommon for these cuts to go to the bone! Report all injuries immediately!
E) Always use a brush to clean the machines. Do not use compressed air to blow the chips off of the machine or your clothes. Never clean the machines while the media is moving.
F) Since the abrasive machines do not have power feed, you will have to feed stock into the blade by pushing with your hands. ALWAYS KEEP IN MIND THAT IF YOUR HANDS SLIP, YOU MAY GET CUT! Keep your hands out of a direct line with the media if possible. If it is not possible, push lightly and be careful.
G) Never wear gloves while using the bench machines. Gloves can very easily get caught, pulling them into the machine and taking your hand with them!
H) Before changing media, make certain that the power to the drive motor is shut down. If you are not sure of the procedure for changing media, ask your supervisor for detailed instructions.
I) Before powering the machine up, make certain all loose tools have been removed from the machine and put in the proper location.
J) Make certain that the tool rests are set to within 1/8” of the abrasive media. If this clearance is not maintained, the workpiece can easily be pulled into the media. This will happen so fast that you may not have time to leave go and your hand may get pulled into the grinder. If the piece goes around the wheel, it will come out as a projectile. You may be in its path. Additionally, the media may disintegrate and become additional shrapnel for you to deal with. IF YOU HAVE ANY DOUBTS ABOUT THE CONDITION OF THE MACHINE, REPORT IT TO YOUR SUPERVISOR!!!
K) MAKE CERTAIN THAT THE MEDIA HAS COME TO A COMPLETE STOP BEFORE ADJUSTING THE TOOL RESTS!
L) Never cut wood, plastic, brass, aluminum, or other soft materials with a grinding wheel. These materials will melt, and the slag will flow into the pores of the wheel, ruining the wheel. Should this inadvertently happen, please report this condition immediately so that repairs can be attempted before someone gets hurt.
M) Soft materials should only be abrasively machined on the belt or disk sander. The media on these machines should be changed if it becomes loaded or worn. Ask your supervisor if you are not certain of the condition of the equipment.
N) Watch for oil or grease spilled on the floor. This is an extreme slip hazard and needs to be reported immediately!
O) ALWAYS USE THE TOOL RESTS WHEN WORKING WITH THE ABRASIVE STOCK REMOVAL MACHINES!!
If you do not know how to operate a machine or do not fully understand the instructions you have been given, ask a supervisor until you are certain about what is required. IF YOU DON’T KNOW, ASK!
In signing this statement, I acknowledge that I have carefully read and fully understand the serious nature of working with machine tools. I also realize that other, undefined hazards will always exist in the machine shop environment therefore, MY OWN SAFETY IS ULTIMATELY MY OWN RESPONSIBILITY.
