Mich. Admin. Code R. 408.14522 - Machine controls
Rule 4522.
(1)
An operating control on a machine, except a stop button, shall be so located or
guarded to prevent accidental contact.
(2) A machine requiring more than 1 operator
shall have controls for each operator which shall be activated concurrently
before the machine will operate as prescribed in
R
408.14541(1).
(3) A machine shall be provided at each work
station with a non-concealed emergency stop device distinguished by its size or
color.
(4) A machine shall be
equipped so that upon power failure it will not automatically restart upon
restoration of the power.
(5) An
automatic die casting machine shall be equipped with a time delay device or
circuit that will prevent the machine from recycling if more than 2 seconds
delay occurs between the automatic demand for recycle and its commencement. It
shall be necessary for the operator to reset the controls before the machine
will restart. Other equivalent means may be used that will prevent recycling
until the machine is cleared if the intent of this subrule is met.
(6) A safety interlock, exposed to contact,
shall be guarded against accidental actuation.
