As industries advance, a number of new techniques are being developed for machine protection – and one of the best is vibration monitoring.
However, it’s important to note the possible hazards you may encounter due to vibration in order to get the most benefit out of your device. If not considered, this can lead to serious problems and critical consequences.
Once you know the main things you need protection from, you can better utilize vibration monitoring to fit your needs.
Vibration Monitoring 101
Often referred to as accelerometers, vibration sensors come in different types, such as:
- Vibration Sensors – Raw sensors
- Vibration Transducers – More complex sensors that output a voltage or current signal
- Vibration Transmitters – Sensors packaged with the means to transmit a more complex output
- Vibration Switches – Using an integral sensor to make or break contact when certain vibration levels are detected
Overall, each vibration sensor measures, displays, and analyzes a machine’s linear velocity (speed), vibration displacement, and vibration acceleration.
Proper guidelines on vibration monitoring can prevent injury.
Hazards of Excessive Vibration
Vibration hazards directly affect your employees, especially those directly involved with machinery. Repeated exposure to high levels of vibration can significantly harm your employees, which is why implementing safety protocols and guidelines is so important.
Typically, vibration hazards are separated into two categories:
Whole Body Vibration
Whole body vibration (WBV) means any instance where vibrations of any frequency are transferred to the human body.
Symptoms include loss of feeling, inability to grip items, and lowered dexterity. These tactile issues also directly affect judgment-making and sensitivity.
WBV is one of the top causes for lost time and production output, according to the Journal of the American Medical Association. It often leads to low back pain and injury.
Also called HAV, hand arm vibration exposure is very serious. It is reported to increase your risk of carpal tunnel syndrome and other ergonomic injuries.
HAV injures your hand and fingers, causing a loss of feeling, dexterity, and grip. HAV injuries are extremely debilitating and often covered by worker’s comp. If left untreated, it can lead to permanent disability.
Working with vibration machines put workers at risk of various health hazards such as mucous disorder, dust-related disorders, and musculoskeletal disorders.
These hazards are connected and may lead to other problems like disability, difficulty in performance of manual tasks, lowered ability to withstand cold temperatures, increased anxiety and stress, and pain or function loss.
How it Affects Your Body
Vibration affects the neurosensory system first, leading to loss of manual dexterity and sensibility. It affects musculoskeletal functions, leading to reduction in the neuromuscular function and even osteoarthritis and muscular pain, plus reduction in manual dexterity.
These effects can be elevated because of ergonomic loads and excessive work in vibration tempered environments; thus, leading to a loss in hand strength.
Varicose veins are also affected. Your blood pressure may change and lead to heart problems if not addressed quickly.
Further exposure to excessive vibration may lead to bone damage and motion sickness.
The amount of damage typically depends upon several factors: the length of exposure, the vibration levels, the frequency of vibration, and amplitude.
How to Protect Your Workers from Excessive Vibration
Set limits on vibration exposure for your workers to keep them safe.
Typically, vibration exposure of 5m/s² is allowed for HAV and 1.15m/s² is allowed for WBV.
Exposure assessment and monitoring are employed for vibration monitoring and measurement. All instruments used should be ISO-8041 certified. The monitoring includes the measurement of daily exposure time and the duration of vibration measurement by using accelerometers.
If you take the above precautionary measures, you can protect your workers from excessive vibration. The right vibration monitoring strategy can help you.
