Bangkok: The Department of Health has issued a warning for residents to brace for elevated PM 2.5 levels on 7-8 February, recommending the use of appropriate masks to mitigate health risks. The PM 2.5 dust concentration is anticipated to remain above the standard threshold of 37.5 micrograms per cubic meter, prompting the department to advise the public on preventive measures.
According to Thai News Agency, Mr. Somsak Thepsuthin, Minister of Public Health, has expressed concern for citizens' well-being in light of forecasts from the Pollution Control Department. The projections indicate that the northern, northeastern, and eastern regions, including Bangkok and its vicinity, will experience PM 2.5 dust levels exceeding standard values during the specified period. Residents are urged to adhere to the "Check, Use, Avoid, Reduce, Close" guidelines, with a strong emphasis on mask usage. The recommended first choice is the N95 mask, known for its high filtration efficiency, certified by standards such as the American NIOSH, European EN149:2001, and Chinese GB2626-2019. Alternatively, surgical masks are advised, provided they meet relevant certification standards.
Dr. Amporn Benjapolpitak, Director-General of the Department of Health, emphasized the importance of proper mask usage. Masks should fit snugly over the nose and chin, and users should assess the fit to ensure comfort. If discomfort occurs, such as difficulty breathing or symptoms like headaches or nausea, alternative protective measures should be considered. Special populations, including young children, the elderly, pregnant women, and individuals with underlying health conditions, may opt for surgical masks. It is crucial to replace masks if they become loose, damaged, or contaminated. Proper disposal methods involve sealing masks in bags before discarding them and ensuring hand hygiene post-disposal.
