A vibration monitor is provided which is worn on the wrist of an operative for an operating plant or apparatus. The monitor includes a piezoelectric transducer and associated circuitry which generates electronic digital signals during the periods when vibrations are experienced by the operative. Preferably, the plant or apparatus has a transmitter which transmits a code identifying the plant which is received by the monitor. Alternatively, the code may be entered manually. The monitor preferably includes a logger which can be connected to a host computer which data can be transferred over an external communications link. The logger includes a storage device for storing how long the operative is subjected to vibrations.
