Mount volcanic dust volcano flying and in order to maintain our health, family and children do not forget to use a mask cover the nose. Because Inhaling volcanic dust is very dangerous for respiratory health. The dust material that enters through the respiratory tract can cause respiratory irritation to the infection, known as ISPA (acute respiratory infection). Exposure to volcanic ash in the respiratory tract can also cause acute effects in people with respiratory diseases such as asthma, bronchitis and enfisema (chronic obstructive pulmonary disease / COPD).
So through this paper I told the people, friends to use a mask when there is volcanic ash.
Masks are self-protective devices covering the mouth and nose (such as those used by doctors, nurses in hospitals at the time of checking their patients or during surgery) are used by a practitioner / worker to protect / prevent / reduce his / her risk of infection / contamination environment.
so hopefully useful thanks
