    • A racking protection device that includes a housing and vibration monitor. The vibration monitor is arranged to record the vibration transmitting through a racking component. The housing includes an alert for alerting a user when the racking requires inspection for damage to impacts. The vibration monitor records the frequency and time of each impact. The vibration monitor includes a memory that counts and records the number of minor impacts. The vibration monitor determines a minor impact when the peak frequency is between a minimum and maximum pre-set level for a predetermined time period. When a predeteiiiiined number of minor impacts is exceeded, the alert is arranged to alert the user to inspect the racking for damage. When the frequency exceeds the maximum pre-set level for a predetermined time period the vibration monitor determines that a severe impact has occurred and the alert is arranged to alert the user to inspect the racking for damage.
