The Importance of Filter Change

The importance of filter change

Filters do not last forever.

3M.com.au/ppesafety 1300 363 565 (AUS) 1 Why and when to replace your 3M filters?

The use of respiratory protection filters can be confusing and complicated and there are a number of common questions and issues that arise regularly. The questions and answers below try to briefly cover these. For complicated and high exposure situations, seek advice from an occupational hygienist or health and safety professional.

Particulate Filters - Protect only against particles There are two Australian Standards i.e. dust, mists and fumes, aerosols, smoke, mould, that pertain to respiratory bacteria and so on. protection.

2 How do particle filters work?

A bed of randomly oriented fibres is used to create the filter. How long do particle filters last? Treated fibres can be used to attract and trap particles as As particle filters load up with the contaminant, they actually they flow into and through the filter material. Increasing the become more restrictive to the passage of particles and can be thickness and capture effectiveness of the filter material a better filter. However, they also become harder to breathe increases the filter efficiency at capturing particles. through. The wearer will notice this increased load and at Particle filters are tested according to AS/NZS1716 Section some point, decide that the restriction is too high and will 4.3.5 and Appendix I and L. The physics of particle capture then need to change the filter. How soon this occurs will also indicates that the particle size range 0.02-0.2 micron be dependent on the amount of particles in the breathing air. equivalent diameter and has a mass median particle diameter A very dusty job will obviously clog the filter up more quickly of approximately 0.3 to 0.6 µm as this is the most difficult size than a relatively clean job. The change decision point will range to capture.

There are four common mechanisms of filtration being interception capture, inertial impaction and diffusion capture When do I replace my particulate filters? and electrostatic attraction.

The benefit of this high efficiency filter can only be achieved on a full facemask of head covering respirator system. It must be at least 99.95% efficient to the most penetrating particle size.

What is a N95 filter level? N95 is the United States National Institute of Occupational Safety and Health (NIOSH) classification that is similar to the P2 rating under AS/NZS1716. N refers to sodium chloride and the 95 refers to these products being at least 95% efficient to the sodium chloride test aerosol. NIOSH also have R and P type particulate filters for oily particulate. In Australia, it is common in healthcare environments for N95 respirators to be used.

3M.com.au/ppesafety 1300 363 565 (AUS) 3 How a gas and organic vapour respirator cartridge works.

3M makes gas and vapour respirator cartridges to help reduce user exposure to many different gases and vapours. To achieve this objective, respirator cartridges are filled with a material called activated carbon. Activated carbon is typically made from coal or renewable resources like wood or coconut shells. It is “activated” by heating the material in nitrogen or steam at approximate temperatures of 800 – 900°C. The resulting material has a significant number of micropores that help adsorb various organic vapours. These micropores can be measured and optimized for specific product needs and performance.

Coal or renewable resources, such as Coal or renewable resources High-temperature steam or nitrogen activation coconut shells are heated without oxygen

When gases and vapours are drawn through an organic vapour High-grade Electron micrographs of cartridge, the air is filtered as vapours condense into the activated carbon activated carbon pores carbon pores. Vapours move through the cartridge from one pore to the next. This occurs more quickly for small volatile vapours with lower boiling points (e.g., acetone). Some migration of organic vapours can even occur during storage, so care must be taken before reusing the cartridge. The effective service life is the time until vapours begin to exit the cartridge.

Unlike particle filters, service life is not indicated by change in breathing resistance. Instead, cartridges must be changed according to local regulations; end-of-service-life indicator; or ™ irritation from the contaminant; or according to 3M Service Unfiltered organic vapours Activated carbon Service life continues until Life Software calculation, whichever comes first. are drawn into the cartridge. absorbs organic vapours vapours begin to escape the on molecular level. cartridge.

Typically, the sorbent is carbon grain, which has been specifically treated. Depending on the chemical treatment of the carbon surface, this material will absorb different types of gases or vapours.

AS/NZS1716 uses a classification system to identify the different types of contaminants these treated carbon grains will capture e.g. A, AX, B, E, K, Hg and G.

Knowing the specific contaminant and exposure levels is important to determine the appropriate respirator, and cartridge or filter for your work environment. This information will also help in estimating the life of selected 3M™ Gas and Vapour Cartridges. If exposure levels are not known, advice and monitoring is required.

While 3M does not carry out exposure assessments or monitoring, we do offer 3M™ Gas Diffusion Monitors (below) which can be a useful starting point. 3M Gas Diffusion Monitors are simple and effective devices that collect certain airborne contaminants using the principle of diffusion. They assist in the assessment of exposure to workplace contaminants, both personal and background. These monitors are easy to use and simply clip onto the shirt, collar or pocket.

Contact the 3M TechAssist Helpline for further information on chemicals which can be captured and approved laboratories for monitor analysis.

3M™ Organic Vapour 3M™ Organic Vapour Monitor Monitor 3500 3520 with Backup Section Uses a single wafer carbon sorbent for Uses a dual layer carbon sorbent for collecting organic vapours. The 3500 collecting organic vapours. Especially suited can be used for most applications, for monitoring compounds such as vinyl particularly suited to routine sampling of chloride, acrylonitrile, methylene chloride exposures to common solvents such as and butadiene for which activated carbon Toluene, Xylenes, Styrene, Naptha and shows limited capacity. The 3520 has 2 White Spirits. layers for increased sampling capacity. Increased capacity may be necessary when sampling volatile compounds (compounds with low boiling points), high or unknown concentrations, complex mixtures or when sampling in high humidity.

3M™ Ethylene Oxide Monitor 3551 Designed for measuring exposures to Ethylene Oxide such as those in the pharmaceutical, health care and chemical industries. The 3551 utilises brominated carbon to collect and convert reactive ethylene oxide to a more stable derivative called 2-bromoethanol. They can be used for 15 minute STEL sampling.
