Noise Emission
Given that there exists a relationship between noise level and exposure times, it is not precise
enough to determine the need for supplementary precautions. The factors affecting the true
level of exposure to operators are clearly the amount of time exposed, the characteristics of the
working environment sources of dust and noise, etc. For example, adjacent machines; in other
words, the level of ambient noise. Therefore, it is recommended that the operator(s) of this
machine wear hearing protection whenever this machine is in operation.
Combustion Hazard
Combustion and Explosion Conditions
The first three elements are those needed for a fire, i.e., the familiar "fire triangle":
•
Combustible dust (fuel);
•
Ignition source (heat); and,
•
Oxygen in air (oxidizer).
An additional two elements must be present for a combustible dust explosion:
•
Dispersion of dust particles in sufficient quantity and concentration; and,
•
Confinement of the dust cloud.
If one of the first three elements is missing, a fire cannot occur.
If one of the above five elements is missing, an explosion cannot occur.
