As the smoke from the Sumatra fire swept through Singapore, more and more people were masked to protect themselves from the smog.
Surgical masks and N95 masks are sold quickly or have been sold out nationwide.
But is there enough protection for either of them?
Particles in smog can increase the risk of a person suffering from viral and bacterial infections, heart and lung disease, cancer, and stroke. According to U. S.
Environmental Protection Bureau (EPA)
, Particles less than 10 microns are dangerous when the respiratory system is inhaled and accumulated.
The agency said on its website that because of the small size of these particles, they can \"go deep into the lungs \".
According to the Health Promotion Committee, smog particles are mainly composed of two kinds of particles.
5 micron or smaller, the N95 shield is effective for particles of about 0. 1 – 0. 3 microns.
\"It protects at least 95 of PM 2. 5 (
Particulate matter 2. 5)
This caused the biggest damage during the smog, \"Dr. Lee Yeow Hian, a respiratory physician at Mount Elizabeth Novena, said in a telephone interview with Yahoo! Singapore.
According to the United States, the N95 respirator mask also provides the closest fit for the face, and users can ensure this by adjusting the strap. S.
Website of Food and Drug Administration (FDA).
According to the health consultation of the Ministry of Health, it should be used according to \"health status, PSI level, physical exertion and outdoor time (MOH).
According to the FDA, those with chronic respiratory, heart, or other diseases affecting the respiratory system should consult a healthcare provider before using the mask, as the mask may require more breathing efforts.
The respirator is not suitable for children because it is not suitable for children.
They are also not suitable for those with facial hair, which destroys the contact of the mask with the skin.
Dr. Li said, \"in order to allow the mask to fit normally, the mask needs to be in direct contact with the skin.
Having a beard can prevent this from happening, as smoke can still pass through the hair.
\"Since we can\'t try on masks before we buy, I recommend that everyone buy a few first in order to find the most suitable one before buying,\" he added . \".
\"Continue to use the mask until it gets dirty or wet and make sure not to fold it, otherwise it no longer provides the proper seal.
According to the Ministry of Health, there is enough N95 mask inventory in the country to meet the expected needs, and \"N95 masks should be purchased only when needed, and there is no need to store them \".
It also said that masks can be found in large retail/pharmacy chains such as Guardian, Unity, refrigeration and Giant, and more will be in stock on Friday night.
The government also reported on its \"emergency 101\" website that 7,000 and 21,000 masks had been distributed to Unity and Guardian on Friday afternoon, respectively.
How to ensure that the N95 mask meets the health promotion board provides a simple guide to wearing the N95 respirator mask on its website.
Surgical masks are also labeled as dental or medical surgical masks and are not as effective as N95 masks.
According to Dr. Li, it \"does not work \".
\"Surgical masks are not used to block any particles,\" he said, adding that they are only effective if they prevent bacterial transmission from patients with flu or cough.
Loose surgical mask-
Install and filter only large particles of droplets, such as splashes, sprays, or splashes, according to the FDA.
Due to loose fit between the mask and the face, the agency says it cannot provide \"complete protection\" from small particles in the air, such as bacteria.
However, due to the strong demand for N95 masks, it is becoming more and more difficult to buy, and Dr. Li said the use of surgical masks is \"better than nothing \".
N95 masks can be purchased from retail outlets such as Guardian Pharmacy and Watsons.
For those who do not have a surgical mask and a N95 respirator mask, they have used bandages and paper towels, and dust and smoke particles can still pass through these materials, Dr. Lee said.
Without masks, Dr. Li advised people to stay indoors and reduce the \"exposure\" of the smoke \".
The Ministry of Health also provided details of medical plans for young and elderly people affected by smog.
