Filtering facepiece respirators (FFR), which are sometimes called disposable respirators, are subject to various regulatory standards around the world. These standards specify certain required physical properties and performance characteristics in order for respirators to claim compliance with the particular standard. During pandemic or emergency situations, health authorities often reference these standards when making respirator recommendations, stating, for example, that certain populations should use an "N95, FFP2, or equivalent" respirator.

This document is only intended to help clarify some key similarities between such references, specifically to the following FFR performance standards:

Gold Coast coronavirus case is a beautician recently returned from Iran

A 63-year-old woman has been put into isolation on the Gold Coast after testing positive to coronavirus.

On Saturday it was revealed the number of confirmed coronavirus cases in Australia has increased by two to 25, including the Queensland woman.

The beautician saw up to 40 people at a Southport salon on Thursday before she started to develop symptoms and went home.

Prime Minister Scott Morrison has moved Australia into pandemic mode, as the coronavirus spreads to 42 countries across the world.

“We’re effectively operating now on the basis that there is one, a pandemic,” Morrison said, declaring the government was now activating its emergency plan.

Using proper cleaning and storage practices ensures that respirators remain effective and uncontaminated.

Common mistakes that limit the effectiveness of respirators.

1. Upon returning from the field on a hot and humid day, a worker haphazardly removes the personal protective clothing. The worker pulls off the respirator and hangs it on a nail in the barn, next to a pesticide container.
2. Rather than taking the time to put the respirator away, a worker tosses it on the dashboard of the truck. The truck is parked in a very sunny spot.
3. A respirator is in an enclosed cab. The cartridge is inside the sleeve of a plastic glove. The respirator has been there for two months.

Respirators should be stored away from dust, sunlight, heat, extreme cold, excessive moisture and damaging chemicals. Respirators, a piece of personal protective equipment (PPE), must be stored away from personal clothing and pesticide-contaminated areas.

People often ask how long a respirator cartridge lasts. The answer is significantly less if they are not properly cared for. I'll admit in the past I have not been kind to my respirator cartridges. I haven't treated them well. I've finished my work and shoved them in the shed with the other painting supplies, or worse left them on the work bench in an the area I just finished painting. As a result, they haven't lasted very long. It's a waste of money, it adds plastic trash to the landfill, and it's just plain irresponsible. I'm sorry.

Understanding the different types of particulate filters and gas and vapour cartridges will help you select the right one.

As per AS/NZS 1715 there are 3 different classes of particulate filters, P1, P2 and P3.

The negative pressure particulate categories are based facepiece coverage. All particulate filtering facepieces that cover the nose and mouth area only can achieve only a P1 or P2 classification. A P3 classification can ONLY be achieved when worn with a full facepiece.

• Class P1 particulate filters are used against mechanically generated particulates e.g. silica and wood dust.
• Class P2 particulate filters are used for protection against mechanically and thermally generated particulates or both e.g. metal fumes.
• Class P3 particulate filters are used for protection against highly toxic or highly irritant particulates e.g. beryllium (when worn with a full facepiece).
• NOTE: certain contaminants may have specific respiratory selection criteria outside this guide e.g. asbestos.
• Gas and vapour cartridges categories are distinguished by their filter type and class. Refer to AS/NZS 1715 for the complete list of filter types and what they are used for. Some commonly used filter types are:
• Filter type A = Certain organic vapours (boiling point above 65⁰C) from solvents such as those in paints and thinners (cartridge label colour = brown)
• Filter type B = Acid gases such as chlorine, hydrogen sulfide (sulphide) and sulfur dioxide (cartridge label colour = grey)
• Filter type E = Vapours from sulfur dioxide (cartridge colour = yellow)
• Filter type ABE = are suitable for both certain organic vapours/acid gases and sulfur dioxide e.g. solvents, chlorine and sulfur dioxide (cartridge label colour = brown, grey and yellow)
• Filter type K = ammonia gas (cartridge label colour = green)
• Filter type ABEK = are suitable for both certain organic vapours/acid gases, sulfur dioxide and ammonia (cartridge label colour = brown, grey, yellow and green)

Novel coronavirus (2019-nCoV)

Information for university and vocational educations students and staff arriving from Hubei Province, China

An outbreak of novel coronavirus (2019-nCoV) was detected in Wuhan, Hubei Province, China in late December 2019.

Coronavirus reaches Australia: Man is quarantined in Melbourne after testing positive to deadly Chinese disease - as seven others are isolated amid fears more Aussies could be infected

• A man has been quarantined in Melbourne after contracting coronavirus 

• The man travelled to Australia alone from Wuhan, via Guangzhou, on January 19

• He initially showed no symptoms, but eventually became ill when in Melbourne 

• There is said to be little risk of the man spreading the deadly virus in Melbourne 

• The Chinese-national is now isolated at Monash Medical Centre in Clayton

• Five people in NSW are being assessed for potential infection of the deadly strain

• Over 40 people have died in China, and 1000 have been affected globally
