Around Vibrating Screens, the 2 primary Safety considerations to have in mind are NOISE and DUST.  These two are harder to deal with than most because of their nature.

A hazard that involves blood and pain is an immediate thing and very easy to understand. But something that may take years of development before it becomes a problem just doesn’t seem that important at the time. As time passes and the effects of the noise and dust start to be apparent they are often mistakenly attributed to aging. The worker will think that he or she is just getting old, not becoming a victim.

You see, both of these dangers effect the worker in slow stages. With dust the sharp edges of the particles scratch the surface of the lungs, and after a time, scar tissue will form. The scar tissue prevents the lungs from processing the oxygen from the air. Breathing wi11 slowly become harder and harder and stairs will become longer and longer. Once the scar tissue has been formed it is there for good and so is the shortness of breath.
With noise, things just become quieter and quieter until nothing is left.

The sad part is that both of these problems are easily prevented. There are many very adequate devices for both dust and hearing protection. But unfortunately some workers feel that ear plugs, muffs and respirators are too uncomfortable to wear.
