Understanding Respirators: Selecting the Right Protection for Your Needs
Respirators are essential personal protective equipment (PPE) in various industries. In this blog post, we’ll provide information on different types of respirators, their applications, and how to choose the right protection for specific needs.
Types of Respirators
P2 (N95) Disposable Respirators: These cover the nose and mouth and filter out at least 95% of respirable airborne respirable particulates and are commonly used in healthcare and construction in situations where the use of the respirator is required sporadically for activity specific purposes. Appropriately fitted to a clean-shaven face, a P2 Disposable respirator may only be used when the exposure of a worker is likely to exceed a workplace exposure standard by less than 10 times.
Half-Face Respirators: These cover the nose and mouth, offering protection against gases, vapours, and respirable particulates depending on the filter cartridge fitted. They are versatile and used in various industries, including painting and agriculture. Appropriately fitted to a clean-shaven face, a Half-Face Respirator may only be used when the exposure of a worker is likely to exceed a workplace exposure standard by less than 10 times.
Full-Face Respirators: These covering the entire face and offer comprehensive protection against gases, vapours, and particulates depending on the filter cartridge fitted. They are essential in environments where significantly elevated exposures are likely or where eye and face protection are necessary, such as chemical handling. For particulate contaminants, appropriately fitted to a clean-shaven face, a Full-Face Respirator may only be used when the exposure of a worker is likely to exceed a workplace exposure standard by less than 100 times.
Powered Air-Purifying Respirators (PAPRs): These also generally cover the entire face (although some half face PAPR are available at lower protection factors). Full face PAPRs use a battery powered fan to draw air through filters, providing high levels of protection and with added comfort factor to the wearer, particularly under strenuous activity. . For particulate contaminants, appropriately fitted to a clean-shaven face, a Full-Face Respirator may only be used when the exposure of a worker is likely to exceed a workplace exposure standard by less than 2000 times.
Supplied Air Respirators (SARs) – Also called Airline Respirators: These also cover the entire face. Full face SARs makes use of a hose to deliver clean, safe air from a stationary source of compressed air supplied from outside the contaminated work zone. These provide the highest levels of protection. SARs limit the range of user-mobility and may fail due to hose damage. Appropriately fitted to a clean-shaven face, SARs are used in any highly contaminated atmosphere.
Choosing the Right Respirator
Selecting the appropriate respirator depends on the specific hazards in your workplace, the level of protection required, and individual comfort. It’s crucial to conduct a hazard risk assessment and consult with safety experts to determine the most suitable type of respirator required.
