Rule 4541. (1) A manually tended die casting machine shall be equipped with 1 of
the following:
(a) Two-hand constant pressure anti-repeat controls requiring concurrent use of both
hands during the die closing cycle. The movable platen shall stop or reverse if either
control is released before the die closes.
(b) A constant-pressure anti-repeat single hand control located at a point where
the operator cannot reach the point of operation. The movable platen shall stop or reverse
if the control is released before the die is closed.
(c) A safety door, interlocked with the control system, which when opened will
prevent closing of the dies. The door shall be of a size to keep the operator from
reaching into the point of operation when the door is closed.
(d) A manually tended die casting machine installed after July 11, 1973, shall be
equipped with an interlocked safety door.
(2) A die casting machine shall have a barrier interlocked to the control system
on the side opposite the operator. The barrier shall cover the die opening in a manner to
prevent an employee from reaching into the point of operation. Where the operation
requires a helper, the barrier may be removed but the controls prescribed in R
408.14522(2) shall be provided.
(3) A die casting machine shall be equipped with an interlocked safety door or by
metal shielding which will protect the operator and other employees from inadvertent
metal splash or squirting from the parting line.
(4) Either a long-handled tool shall be furnished and used to remove castings or
flash from a die casting machine if they are not automatically extracted or ejected or the
employee shall be protected by a mechanical device which automatically prevents
closing of the machine.
(5) An automatic die casting machine shall be equipped with interlocked doors or
barrier guards of a size and design to keep an employee from reaching into the point
of operation. A door or barrier may be removed or maintained in an open position where
an extractor would interfere with its use, if the extractor is guarded as prescribed in R
408.14544.
