Toxic Gas Threat Behind the Merapi volcano ash rain

The rain of ash is not the only threat of the eruption of Mount Merapi, because bursts of volcanic material that is usually accompanied by toxic gases. Because of its mild and colorless gas that sometimes slide further but not realized. 3 types of toxic gas that can be found in any volcanic eruptions, including Mount Merapi. All three are sulfur dioxide, carbon dioxide and hydrogen sulfide.

sulfur dioxide poisoning is characterized by difficulty breathing, chest pain, irritation to eyes, nose and throat, coughing and others. Because it contains sulfur, are easily recognizable from the stinging stench that can cause shortness of breath.Poisonous gas that is also easily recognizable from the odor is hydrogen sulfide, which smells like a fart sharp. In the lower levels even if this gas can lead to irritation of the eyes, while at high levels can irritate penafasan channel.While the poisonous gases from volcanic eruptions that its appearance is often not realized because carbon dioxide is odorless. And this gas has a higher density than air, so easily carried away to a place that is lower settlements.Increased carbon dioxide can cause respiratory problems, with appropriate severity levels in the inhaled air. At levels of more than 5 percent of this gas can cause shortness of breath, while at levels more than 30 percent can cause death.

several steps to prevent the negative effects of poison gas.
