Rationale
The
two-hand push button control devices are commonly used in
press machines to ensure that both hands are busy while
the machine is performing a dangerous motion.
However, these controls are oftentimes blocked or
bypassed to ease operation, and to speed up production;
thus, jeopardizing the safety of the operator.
This
device is designed to require simultaneous pressing of the
controls and releasing them prior to the next operation;
thus, preventing workers from making the safety device
inoperable, and avoiding mishaps.
Objectives
1.
To develop a low-cost safety device that can
effectively prevent work-related accidents
2.
To evaluate its efficiency in terms of controlling
accident and productivity.
Methodology
1.
Design and develop a two-hand push button safety
device capable of withstanding continuous operation
2.
Pilot-test the device in the industrial sector.
3.
Monitor and maintain the safety device.
Features
The
main function of this safety device is to protect the
operators from possible injury.
The simultaneous pressing of two push buttons to
allow movement of the die makes it impossible for the
operator’s hands to be caught in between the upper and
lower dies.
The
use of safety relay prevents the worker from permanently
tying the switch so that it can be operated with one
switch, while the other hand is in action.
The
attention of the operator will no longer be divided
between the work he is doing and the fear of being
injured, thereby making him more productive and effective.
