(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.Mich. Admin.
