Why Coupling Guards Matter

If a flexible coupling breaks during operation, it can result in a serious accident. Unfortunately, coupling guards are often removed during maintenance, which is a common but dangerous mistake on many sites. In the event that a coupling with a 3-inch radius detaches from a running pump or motor, the lack of a guard can cause it to be ejected at high speed in any direction. Given that the pump's shaft rotates at 1450 revolutions per minute, the velocity of the detached part can be extremely dangerous.

Although the piece may travel at a slower speed (11.56 m/s) compared to a bullet, its weight and momentum make it a significant hazard. Momentum shows that even slower-moving objects, if heavy, can cause serious harm. This incident highlights the critical importance of maintaining safety guards. Failing to do so not only endangers workers but also risks damaging expensive equipment and causing costly production delays.

Always prioritize safety in the workplace. Essential safeguards, like coupling guards, are designed to prevent avoidable accidents and should never be overlooked.
