Sources Of Vibration Vibration results from some part of moving machinery being out of balance, turbulent fluid flow, rattling of loose objects, impulses, shocks etc. Vibration is normally undesirable but it can be reduced by careful design or by development modification. Some times, however, vibration is introduced to make things work, such as vibrating conveyor belt, mechanical hammers and even musical instruments. In such cases resulting noise is unavoidable. It is then important to isolate it as much as possible by providing barriers like Protective Personal Equipment (PPE).
IMPORTANT EFFECTS OF VIBRATION ON HUMAN HEALTH –
Excessive exposure to high vibration offers following gifts to Human beings:
o Blurred vision
o Loss of balance
o Retardation in performing the task
o Damage of internal body organs
o Fatigue
o Noise generation
o Irritation
Blurred vision: Person capability in identifying the object reduces due to regular shaking of object.
Loss of balance: Fluid near the ear gets disturbed due to continuous vibration. As this fluid is providing the balancing sense to Human being, we loose the balance until the fluid is brought to stable condition.
Retardation in performing the task: Personnel perform at reduced rate in vibrating environment.
Damage of internal body organs: Tissues get disturbed. Microbial movement gets disturbed due to vibrating scenario. This amounts to internal damage which could be well experienced during journeys by elderly persons.
Fatigue: Repeated impact takes place in vibrating environment and that is why the tiring conditions are faced due to fatigue.
Noise generation: Leads to vascular effects, hypertension as a result of blood pressure rise.
Irritation: Vibration and noise combined effect results in irritation of the personnel subjected to this environment.
Your Views?: Have you ever encountered issues that you suspect could be associated with noise vibrations all around you? Share your views and comments, we would love to get your feedback and hear from you!!!
