ILOILO CITY — In light of the recent eruption of Mt. Kanlaon, the Iloilo City Government has issued a public health advisory warning residents about the health risks associated with volcanic ash, gases, and other hazardous materials. Wearing a mask is essential, and the public is urged to stay informed and safe.
Understanding Volcanic Ash and Its Health Effects
Volcanic ash consists of powder-size to sand-size particles blown into the air by an erupting volcano. Exposure to falling ash may cause a number of health problems, including nose and throat irritation, coughing, bronchitis-like illness, and discomfort while breathing. Eye irritation and minor skin problems are also common. More severe risks include injuries or death due to roof collapse or vehicular accidents resulting from slippery roads and poor visibility.
Anyone who already suffers from health problems such as bronchitis, emphysema, or asthma should avoid exposure to volcanic ash. The Department of Health has emphasized that these vulnerable groups face heightened risks. Children, the elderly, and individuals with pre-existing respiratory conditions are particularly susceptible to the fine particles that can penetrate deep into the lungs.
Before the Ashfall: Preparedness Steps
Preparation is the first line of defense. Residents are advised to listen to the radio for updates from authorities when an impending eruption may cause ashfall. Prepare an emergency supply kit and place it in an accessible area. Essential items include first aid kits and medications, food and water, flashlights and batteries, a radio, dust masks, goggles, blankets, and emergency contact numbers.
Families should also prepare dust masks or clean cloths for covering the nose and eyes, cleaning supplies such as brooms and vacuum cleaners with spare bags, and enough food and water for pets, poultry, and livestock. Know the location of evacuation areas and ensure children know their school's emergency plan. Having indoor games and activities ready for children will help ease anxiety during extended periods indoors.
During the Ashfall: Protective Actions
When ashfall occurs, stay calm and stay indoors. Close all windows and doors of the house and your car. Place damp towels or cloth at door openings and other open sources to prevent ash from entering. Cover your nose and mouth with a damp, clean cloth or dust mask. Keep pets inside or in a sheltered area to avoid inhaling ash.
If driving, pull to the side of the road and stop if there is heavy ashfall which causes poor visibility. If you are outside, look for shelter and wear glasses to protect your eyes. Avoid using contact lenses. Wash all fruits and vegetables thoroughly before eating, and cover water containers and food to avoid contamination from ash.
After the Ashfall: Recovery and Cleanup
After the ashfall diminishes, scrape off the ash that has accumulated on rooftops to prevent collapse. After removing ash from the roof and gutter, wash with water to prevent corrosion. Remove ash from windows and doors of the house and car, and use water before washing them with soap and lukewarm water.
Collect the ashes and put them in a container or water drainage to avoid clogging. Wash grass before feeding the animals or livestock, and boil water before drinking. Use powder detergent in washing clothes covered in ash. Use a vacuum cleaner or shake the furniture to loosen and clean the ash, covering your nose and mouth while cleaning.
Iloilo's Proactive Response
The Iloilo City Government, through its City Disaster Risk Reduction and Management Office, actively monitors air quality indices and issues timely safety bulletins and face mask recommendations during peak sulfur dioxide episodes. Municipal health units coordinate public health alerts to ensure community safety and minimize exposure risks across Western Visayas.
While Mount Kanlaon is situated across the strait on Negros Island, its eruptive activity directly and indirectly influences Iloilo Province and Iloilo City due to regional wind dynamics. Prevailing wind patterns frequently carry volcanic gas plumes northwest toward Panay Island, resulting in hazy conditions and sulfurous odors across Iloilo. The public is urged to always monitor advisories and updates about the eruption.
