, by Tatianna Gerard, 15 min reading time
In high-risk environments, workers are often exposed to airborne hazards that can lead to serious health issues over time. Dust, fumes, bacteria and infectious particles are just a few of the dangers that can compromise respiratory health, especially in industries like construction, healthcare, and agriculture. To mitigate these risks, respiratory protection is essential, and one of the most commonly used forms of protection is the P2 mask.
P2 masks are designed to filter out at least 94% of airborne particles, making them a vital tool in protecting workers from inhaling harmful substances. However, while P2 masks are highly effective in many settings, they are not suitable for all environments. In some high-risk jobs, such as asbestos removal or certain types of mining, more advanced respirators are required to ensure complete protection.
In this blog, we will explore the role of P2 masks in the workplace, examining the industries where they are most beneficial, as well as the limitations that need to be considered when selecting the right respiratory protection for the job.
What is a P2 mask? How does it work?
A P2 mask is a type of respiratory protective device designed to filter out harmful airborne particles, offering a minimum of 94% filtration efficiency for particles as small as 0.3 microns. This makes it highly effective at protecting workers in environments where fine dust, aerosols, or pathogens are present. P2 masks are commonly used in industries such as construction, agriculture, and healthcare, where exposure to airborne hazards is a regular concern.
Some of you may be confused about the difference between a P2 mask and an N95 mask. While both masks are designed to provide protection from airborne particles, the key difference lies in their filtration efficiency and standards. N95 masks offer a higher filtration efficiency of ≥95%, meeting the stricter standards set by the US regulatory authorities, while P2 masks meet Australian and New Zealand standards, with a ≥94% filtration efficiency.
Filtration technology in P2 masks
P2 masks are designed with specific filtration technologies that enhance their protective capabilities. Two of the most common filtration methods used in P2 masks are meltblown and nano-fibre technology.
Meltblown filtration:
This is a widely used technology in which ultra-fine fibres are created by melting a polymer and blowing it through high-pressure air. These fibres form a dense filter layer that effectively captures particulate matter, offering high filtration efficiency. Meltblown filters are commonly used in many P2 masks, providing excellent protection against dust, smoke, and other airborne particles.
Nano-fibre filtration:
Another advanced filtration technology used in P2 masks is nano-fibre. Nano-fibres are even smaller than traditional fibres, offering superior filtration efficiency and allowing for a finer, denser mesh that captures even smaller particles. Nano-fibre technology is becoming increasingly popular due to its enhanced protection capabilities, especially in environments with a higher concentration of fine particulate matter.
One example of a mask that utilises nano-fibre technology is the Australian-made AMD P2 Respirator, which is designed to provide top-tier filtration for a wide range of airborne hazards. With its nano-fibre technology, the AMD P2 Respirator offers improved particle capture, making it ideal for workers exposed to fine dust, smoke, or other fine particulates in demanding environments. This innovation ensures that users benefit from enhanced protection, combining the latest in filtration technology with the trusted quality of Australian manufacturing.
Both of these filtration technologies are designed to ensure that harmful particles are effectively trapped, preventing them from being inhaled into the lungs. However, the choice between meltblown and nano-fibre technology can influence the overall performance of the mask, with nano-fibre generally offering a more advanced and durable solution.
Industries that benefit from P2 mask use
P2 masks are an essential piece of personal protective equipment in many industries, where workers are routinely exposed to airborne hazards. These masks provide an effective barrier against dust, fumes, and particles, ensuring the safety of employees in various high-risk environments. Below are some of the industries where P2 masks, including the AMD P2 respirator masks, play a crucial role in safeguarding workers’ respiratory health:
Construction industry
The construction industry is one of the primary sectors where P2 face masks are used to protect workers from airborne dust and particulate matter. During activities like sanding, demolition, and mixing cement or plaster, fine dust particles can be released into the air, posing significant health risks if inhaled over time. P2 respirator masks are designed to filter out these harmful particles, preventing respiratory conditions such as asthma, and other lung diseases. Workers involved in tasks like cutting, grinding, or plastering benefit greatly from the protective capabilities of P2 respirators, which offer high-efficiency filtration.
Healthcare and medical settings
In healthcare environments, P2 respirators provide protection against airborne infectious diseases, such as tuberculosis, flu, and COVID-19. Medical professionals, including doctors, nurses, and laboratory staff, are often exposed to infectious particles in patient care settings or when handling medical samples. P2 masks help reduce the risk of inhaling bacteria, viruses, and other pathogens, offering a vital layer of protection for those working in hospitals, clinics, and other healthcare facilities. While surgical masks are typically used in lower-risk situations, P2 face masks provide more robust protection in environments with higher concentrations of airborne pathogens.
Agriculture and farming
Agricultural workers are regularly exposed to airborne particles such as dust, pollen, pesticides, and animal dander, all of which can trigger respiratory issues like asthma or allergic reactions. Additionally, agricultural environments, particularly in tropical regions, can present the risk of contracting melioidosis, a bacterial infection that affects the lungs and can be contracted through inhalation of contaminated dust or soil. P2 masks are commonly worn during activities like grain handling, pesticide spraying, and when working in areas with high levels of airborne allergens, animal waste, or contaminated soil. These masks help filter out fine dust, chemicals, and pathogens, protecting workers from long-term lung damage and potential infections like melioidosis.
Additionally, P2 face masks are beneficial for farmers working in areas prone to seasonal crop dust or environments with high levels of hay or silage dust, ensuring they have the respiratory protection they need to safeguard their health and prevent respiratory infections.
Manufacturing and warehousing
In manufacturing plants, warehouses, and factories, workers may be exposed to a variety of airborne contaminants, including fine particulate matter from welding, grinding, and other industrial processes. P2 respirators help protect workers from inhaling dust, fumes, and vapours that could cause chronic respiratory conditions. In environments where substances like wood, metal, or plastic are processed, P2 masks are essential for ensuring the long-term health of employees. Similarly, warehouse workers handling products like flour, sugar, and spices, which create airborne dust, benefit from P2 respirator masks to avoid inhaling fine particulates.
Food processing and handling
Food production workers are often exposed to airborne allergens, dust, and fine powders in environments such as flour mills, bakeries, and food factories. P2 masks are crucial in protecting workers from inhaling particles that could cause respiratory irritation or long-term health issues. For example, workers in flour mills or those packaging powdered foods are at risk of developing conditions like baker's asthma or allergic alveolitis, which can be prevented by using P2 face masks. These masks also help in preventing contamination by minimising the risk of inhaling harmful substances during food production processes, making masks an ideal choice for workers in this industry.

When P2 masks are not suitable
While P2 masks are highly effective in many work environments, they are not appropriate for all situations. It's essential to recognise when P2 respirators are not suitable, as relying on them in high-risk environments could expose workers to dangerous levels of harmful particles or gases. Below are some instances where P2 face masks are not the right choice for respiratory protection:
1. Asbestos removal
Asbestos is a highly toxic material that can cause severe respiratory conditions, including asbestosis, lung cancer, and mesothelioma. P2 masks are not suitable for environments where asbestos is present because the fine asbestos fibres are much smaller than what P2 masks are designed to filter out. To protect workers from inhaling these deadly fibres, much more advanced respiratory protection is required, such as P3 respirators or full-face respirators equipped with specific filters that can capture even the smallest asbestos particles. In any case where asbestos removal or handling is involved, it is vital to ensure the correct respiratory equipment is used.
2. Mining and silica dust exposure
In industries such as mining, workers may be exposed to silica dust, which is highly hazardous and can cause lung disease, including silicosis. P2 masks do not provide adequate protection against the fine and toxic particles found in silica dust. For these environments, a P3 respirator or more specialised equipment is necessary to provide sufficient protection. P2 respirators are effective for blocking everyday dust particles, but they are not suitable for environments where the concentration of toxic dust or particulate matter exceeds their filtration capacity.
3. Chemical and gas exposure
P2 masks are designed to filter out solid particles, but they do not offer protection against gases, vapours, or fumes. In industries where workers are exposed to hazardous chemicals or toxic gases, such as in chemical plants, laboratories, or areas dealing with industrial solvents, a P2 respirator mask is not enough. Instead, workers should use gas masks or chemical-resistant respirators that are designed to filter out harmful gases and vapours. These specialised respirators have additional filters that can protect against chemicals and hazardous fumes that P2 masks are not equipped to handle.
How to select the right respirator for your workplace
Selecting the right respirator is crucial for ensuring the safety and health of workers in environments with airborne hazards. The right choice depends on several factors, including the type of contaminants, their concentration, and the specific risks associated with the job. Below are key considerations to help guide your decision-making when choosing a respirator for your workplace:
1. Identify the type of hazard
Before choosing a respirator, it's essential to understand the specific airborne hazards present in your workplace. Are you dealing with dust, fumes, gases, or pathogens? Different types of respirators offer varying levels of protection against different contaminants:
-
Dust and particulates: For dust and fine particulate matter (e.g., construction dust, pollen, or grain handling), P2 masks are effective as they filter out 94% of airborne particles ≥0.3 microns.
-
Gases and vapours: If you're working in an environment with gases or vapours, such as chemical processing, a P2 respirator mask will not provide sufficient protection. In these cases, a gas mask or chemical respirator should be used instead.
-
Airborne pathogens: If you're working in healthcare settings or dealing with airborne pathogens (e.g., tuberculosis or flu), masks with higher protection levels, like N95 or P3 respirators, may be required to ensure adequate filtration. Standard P2 masks might not be helpful but AMD’s nano-fibre P2 masks offer ≥99.66% Particle Filtration Efficiency (PFE), and ≥99.92% Bacterial Filtration Efficiency (BFE) which makes it the more suitable type of P2 mask to be worn in medical environments.
2. Consider the filtration efficiency
When selecting a respirator, pay close attention to its filtration efficiency (PFE) and bacterial filtration efficiency (BFE). The particle filtration efficiency determines how effective the mask is at capturing harmful particles, while BFE focuses on how well the mask prevents bacterial transmission.
For instance, AMD P2 masks offer impressive filtration capabilities with a ≥99.66% PFE and ≥99.92% BFE. These high-efficiency P2 respirator masks are ideal for environments where fine particulate matter is prevalent, such as construction sites, food processing, medical or agricultural settings, where the air is filled with dust, allergens, or contaminants. Their exceptional performance makes them a reliable choice for ensuring worker protection in environments where both dust and airborne pathogens could be a concern.
3. Fit and comfort
A key factor in selecting a respirator is ensuring that it fits properly. A well-fitting mask creates a seal around the nose and mouth, preventing harmful particles from bypassing the filter. P2 respirators should be tested for fit, especially for individuals who may wear them for extended periods. Masks that don't fit properly may allow air and contaminants to leak in, reducing their effectiveness. For added comfort during long hours of wear, choose respirators with adjustable straps, a soft seal, and breathable material.
4. Duration of use and maintenance
Some work environments require continuous use of respiratory protection for hours at a time. In these cases, comfort and breathability are critical factors when selecting a respirator. AMD P2 masks, for example, are designed with comfort in mind, offering lightweight and breathable materials, making them a suitable option for workers who require prolonged wear in environments with moderate airborne risks.
However, it’s important to note that most P2 masks are designed for single use and are disposable. For safety reasons, disposable P2 face masks should be replaced after each use or when they become damaged, so they can maintain their full protective capacity. Reusing P2 respirators can compromise their effectiveness, which is why they are generally intended for short-term exposure scenarios.
