The Department of Health (DOH) urged the public, particularly those living near the Taal Volcano, to be vigilant and wear the necessary equipment in order to protect themselves against sulfur dioxide and ashfall.

“In view of recent developments at Taal Volcano, the Department of Health advises the public residing at or near its shores and other high-risk areas to be vigilant,” the DOH said in an advisory.

The public should remain on guard for sulfur dioxide inhalation, said the DOH. Sulfur dioxide is a “colorless toxic gas” and a person may be exposed to it by “breathing air containing sulfur dioxide or through skin contact.”

“Short-term exposures to sulfur dioxide can harm the human respiratory system and make breathing difficult. People with asthma, particularly children, are sensitive to these effects,” the DOH said.

The DOH advised residents to avoid unnecessary trips out of their houses; close the doors and windows, especially if you are living near the caldera of Taal Volcano; and always wear a face mask, protective gears for eyes, and coverings for the skin.

Volcanic ash

The DOH also warned the public against volcanic ash. “Exposure to falling ash may cause a number of health problems. Anyone who already suffers from problems such as bronchitis, emphysema, or asthma should avoid exposure to volcanic ash,” it said.

Some of the adverse effects if exposed to volcanic ash include nose and throat irritation, coughing, bronchitis-like illness, discomfort while breathing, eye irritation, minor skin problems,” the DOH said.

This may also cause injuries or death due to “roof collapse or vehicular accident resulting from slippery roads and poor visibility.”

Here are some ways to minimize exposure to volcanic ash according to DOH: stay indoors as much as possible, keep doors and windows closed; keep home from infiltration by using damp curtains, blankets, or clothing; use dust or N95 mask; wear goggles or eyeglasses to protect eyes from irritation; keep pets in closed shelters; dampen ash in your yard to prevent it from billowing up into the air, clear your roof of ash, and observe traffic notifications and road safety measures.
