What are the Importance of respiratory mask, their types & uses
Since the beginning of the industrial revolution, the quality of the Earth’s air has been degrading steadily. Large-scale production and harnessing the power of chemicals for the purpose of war have pumped large amounts of harmful substances into the air. However, technology has also given us equipment to protect ourselves from polluted air. One such amazing invention is respiratory mask.
Importance of respiratory masks
We are hardwired to protect ourselves from dangers that we can see. However, we can’t see harmful particles in contaminated air or dangerous, invisible and odorless gases. So, in essence, air pollutants are silent and invisible killers.
Polluted air means less oxygen. This leads to impaired thinking, inefficient coordination and increased heartbeat. When you are in a dangerous environment, these issues can lead to serious injury or sometimes death. It is therefore important that people, who are exposed to such work environments, wear respiratory masks.
Respirator masks filter harmful particles, vapours, fumes and gases. These are life-saving devices used by industrial workers, soldiers and public alike. There are a wide range of respiratory masks. Coming in the form of disposable and low-prized masks like the n95 mask to sophisticated military-grade masks, they are among the most ubiquitous and popular Personal Protection Equipment.
Types of respirators
We can broadly classify respirators into two main categories.
1) Air-purifying respiratory mask: These devices use a filter material to stop air contaminants from getting into the lungs of the wearer. Such devices are normally low-priced and are used by public and professionals. A common type of this mask is the N95 mask.
These are used by:
Law enforcement officers
The surgical mask used by doctors can also be included in the category of air-purifying respirator.
2) Air-supplied respirator: The devices supply clean air from an outside source. Such respirators are normally safer than air-purifying respirators. However, their major limitation is that they need an additional source, which shortens their range and portability.
These are used by:
The air-supplied respirators are further categorized into several subsections. Just like different categories of extinguishers can put out flames on different kinds of materials, there are different kinds of respirators capable of filtering different kinds of contaminants.
Many people buy dust respirators online, as e-commerce sites offer a large variety of respirators. The n95 mask price, like many other PPE products, differs in various sites. However, before buying respirators online, you need to weigh your needs and the amount you can afford to spend.
Respiratory masks are life-saving devices. These are one of the major devices that come under PPE. This amazing invention has played a major role in reducing casualties of workers, who are often exposed to dangerous air contaminants.
