					 plate should be put on a lathe by power, nor should any chuck wrench or key be
					 left in a chuck. When filing on a lathe, the file should be held so that if it
					 is forced back it will not be forced against the user, but to one side. Filing
					 should be left-handed with the right hand across stock when filing near the
					 chuck end of a lathe.
(c)
Drills.
Any material to be drilled should be securely
					 fastened, but never held by hand. Hands, cotton waste or rags should never be
					 used to brush borings away from the work; a brush should always be employed for
					 this purpose.
(d)
Grinders.
Any material to be ground should be held firmly
					 against the steady rest in front of the wheel. Such steady rest should be
					 properly adjusted and as near to the wheel as possible. The sides of emery
					 wheels should never be used for grinding unless they are designed for side
					 grinding.
