Make sure two-hand trip devices used to safeguard the point of operation meet these requirements.
You must:
⢠Make sure presses requiring more than one operator:
â Have separate two-hand trips for each operator.
â Need concurrent application of all operators' controls to activate the slide.
⢠Make sure the two-hand trips are fixed in position and can be moved only by authorized persons.
⢠Make sure the controls are located farther from the point of operation than the minimum safety distance as determined by the following formula:
DÂ =Â 63 x T
Where:
DÂ =Â minimum safety distance (in inches)
TÂ =Â the maximum time the press takes for the die to close after the press has been tripped (in seconds)
Example:
The number in the formula represents the hand speed of the operator (63 inches per second). If your press has a die closing time of one-half second (.5 second), the calculations would be:
Â
DÂ =Â 63 x .5Â =Â 31.5
Â
The trip devices would need to be at least 31 1/2 inches from the point of operation.
