Mich. Admin. Code R. 408.40127 - Machine installations and guarding
Rule 127.
(1)
The power source of any machine that is to be repaired, serviced, or set up,
where unexpected motion or an electrical or other energy source would cause
injury, shall be locked out by each employee doing the work, except when motion
is necessary during setup, adjustment, or troubleshooting. Any residual
pressure shall be relieved before and during the work. A machine connected by a
cord and plug to an electric power source shall be considered in compliance if
the plug is disconnected and tagged and the disconnection is within view of the
operation.
(2) An employee shall
not place his or her body beneath equipment such as a vehicle, a machine, or
materials, that is supported only by a jack, overhead hoist, chain fall, or any
other temporary single supporting means, unless safety stands, blocks, or
another support system that is capable of supporting the total imposed weight
is used to protect the employee if the temporary single supporting means
fails.
