ANSI B11.6-1984 prescribes the installation of a safety circuit to nullify opening or
closing of the chuck during its rotation, and the need to protect the operator from
inadvertent opening or closing of the chuck, usually by a shield.
ANSI B11.6-1984 also requires that when a foot pedal switch is used, it must be
protected from inadvertent operation.
3.6.4 End of Operations

into contact with a spinning chuck whose top jaws or gripped
work piece have irregular contours which are not readily visible
while rotating. A door or guard must be provided to prevent
anyone from approaching the spinning chuck.
Remove the work piece from the chuck at the end of operations. If
the work piece is left gripped in the chuck, the cylinder supply
pressure may decrease, or the work piece may fall oft due to
mistaken operations, it may cause severe personal injury and
machine damage.
