Are you qualified to talk about this?

Yes. I [Tekenduis] am a Certified Respiratory Protection Tester/Trainer with extensive training in respiratory protection. I work at a company where my staff are exposed on a daily basis to some of the most harmful chemicals in industry. They can and will be exposed to things like silica, isocyanates and cyanide gas. Their short and long-term health is in my hands and I take that very seriously. Deadly seriously, in fact.

What is respiratory protection?

Respiratory protection is a part of your Personal Protective Equipment (PPE) designed to filter or block harmful substances from reaching your respiratory system. The hobbyists primary form of respiratory protection is the respirator. There are a great number of types of respirators, some useful only for certain applications (see more on this below). The two most common respirators for hobbyists are the disposable respirator and the half-face respirator.

The half-face respirator is a mask that covers your nose and mouth, and has cartridges that clip on, screw on, or otherwise attach to ports on the mask.

The disposable respirator looks like a dust mask or surgeon's mask. It is, as the name implies, made to be disposed of after a short period of time.

Why do I need it?

Many of the items that we work with as doll customizers are toxic and many of them are cumulatively toxic. You may feel ill for a while and then get better, but the sorts of diseases that can be caused by sanding processes and spraying processes can come back to haunt you many years down the road. These products can cause Cancer and Pneumoconiosis. Cancer may be treatable if caught early enough. Pneumoconiosis, which is respiratory diseases like asbestosis, silicosis and coalworker's "black lung" disease, is NOT TREATABLE. Your doctors will work hard to make you comfortable while you die. That is the most they will be able to do for you. If you get Pneumoconiosis you will DIE.

☠️ Are you scared? You should be. This is life and death. Do not play Russian Roulette with your health. ☠️

What do I need?

That depends on the application that you are going to be using your respiratory protection for.

Sanding

For sanding applications (including sanding of resin, apoxie and other sculpting materials, and wood), you need a respirator that provides at least N95 level protection. It should say N95 somewhere on the mask itself. If it doesn't say, it is not good enough. There is a scale to protection levels and anything above N95 is also acceptable (of course).

The levels are: N95 P95 N100 P100

What does this mean?

The prefix ahead of the number will tell you if the mask is Oil Proof or Not. The number will tell you the percentage effectiveness of the filter against particles of less than 0.3 Microns. An N100 or P100 filter may also be known as a HEPA filter. On the bright side, having a small supply of these types of respirators will mean that you are following CDC and WHO recommendations for infectious disease outbreaks, which may or may not include the Inevitable Zombie Apocalypse.

P100 filters are also effective in welding applications. N95 and above filters are most commonly found in the disposable variety and may also be referred to as "dust masks" or "surgical masks". Remember, if it doesn't say N95 (or one of the other codes listed above) it is not good enough!**

Spray

This includes all types of spray applications, whether you are spraying sealant (like MSC or Testors) or airbrushing or spraying paints. The process of spraying releases aerosols (and this is true whether or not you are using an aerosol spray can product. Airbrushing paint creates aerosols too!) for which an N95 filter is not effective.

At this point, you will need to move into a mask that protects you against Organic Vapors AND has an N95 filter. This will mean moving into a half-face respirator.

Your respirator is no longer disposable and can be used again and again without ill effect; the only thing that will need replacing is your filter and (if applicable) your prefilter. Some respirator brands have an N95 filter built right into the Organic Vapour cartridge, but I recommend looking for one that does not, for ease of replacement. Cartridges and filters have different life spans and it is more economical to replace only the part that requires replacing (more on this below!).

Okay! I've got my mask, I'm totally safe now right?

No. There are three things that can negatively impact the safety of your mask; poor fit, improper maintenance and environmental levels.

Poor Fit

A respirator (of any type) is completely and utterly useless if it is the wrong size for you and is not fitted properly. Please ensure you've read the section on fitting your mask to ensure that your mask is correctly fit.

How do I know if it fits?

According to my local Occupational Health and Safety Code, a respirator cannot legally be used in a workplace environment if it has not been correctly Fit Tested. Keep in mind that half-face respirators come in various sizes. Most women and men wear a medium but if you have a particularly slender or wide face, you may need a small or large. If you have a crooked nose, or sinus problems, look for a mask made of silicon; you will find it more comfortable than plastic or rubber.

Improper Maintenance

Your respirator is equally useless if you are not properly maintaining and caring for it. This includes care of the mask between uses and replacement. Please see the section on maintaining your mask for more information.

Environmental Levels

Environmental levels are important to take into account, as your mask can only protect you against the things it was designed to protect you against up to a certain concentration. since I'm sure none of us have the money or inclination to commit to environmental testing of our workspaces, the best way to ensure this is to make sure that the area in which you are working is properly ventilated before you start your project, and until well after you are finished. Open your windows, PREFERABLY PLEASE work outside so that there is fresh air circulating in the area you're working in. If the air is particularly still (no breeze) while you're working, it is worth investing in a simple fan. Set it up in your window, with the fan blowing out the window (ie: the front of the fan where the air blows from facing towards the window). This will help pull the toxins out of your room. Alternately, if you are working outdoors, set the fan up on your table to help promote air movement.

Fit Testing

Fit testing uses a noxious but harmless substance (usually either irritant smoke or Bitrex; an additive used to create bitterness in household cleaners to prevent children from tasting them) to ensure that the seal between the mask and the face is tight and proper. Qualitative fit testing is the most common type, and requires the user of the mask to confirm the presence of the noxious substance. In some cases (depending on chemicals in the environment or failure of the Qualitative test) Quantitative fit testing may be required; this type of fit testing uses scientific sensors to record levels inside the mask. If you have access to fit testing, especially with a half-face respirator, I encourage you to take advantage of it! Fit testing needs to be redone every two years, in the case of weight loss or gain of more than 15 lbs or in the case of surgery (including dental) involving the face.

And if I don't have access?

I have done hundreds of fit tests for staff at my place of employment and I can usually tell how well a mask is likely to fit prior to the fit test being done. This is done with a simple self test. In order to be effective this test must be done every single time you use the respirator (even if you pull it down to talk to someone and put it right back on!).

For Disposable

Step 1: Put your respirator on. Step 2: Cup your hands tightly over your mouth and nose, over top of the respirator. Step 3: Suck in a long breath. You will get air, but it should all be coming in through the small cracks between your fingers. You should not feel any air coming in from around the nose piece or under your chin. If you do, refit the mask and try again. If you cannot complete this successfully, you will need either a larger or smaller mask. Step 4: With your hands still over your mouth and nose, blow out. Again, you should feel the air moving past your fingers, and never around the bridge of your nose or under your chin.

For Half-Face

Step 1: Put on your mask and make sure the straps are tight. Step 2: Cover the cartridge, as much as possible, with the palm of your hands and suck in. The mask will likely deflate slightly. You should feel some air coming in through the cartridge but no air coming in from the sides, under your chin, or around your nose. If you do, adjust the mask and try again. If you cannot complete this step successfully, you will need either a smaller or larger mask. Step 3: Cover the exhalation valve of your respirator with the palm of your hand and blow out. You should feel the mask inflate slightly and again, you should feel no air escaping from the side of your mask, under your chin or around your nose.

😷 How do I maintain my mask?

Respirator maintenance is exceptionally simple, takes very little time, and ensures that you are not exposing yourself to toxins. Take the extra few minutes to ensure that your respirator is working right!

Before you put it on

For Disposable

Do a quick visual check of the respirator. Is it dirty? A little discolouration from the dust is fine, but too much might mean that your respirator is clogged. I'll discuss this a bit further down. Check that your straps are still in good condition. Check that the foam piece at the nose is intact (if applicable) and that the metal part that bends across your nose is not bent out of shape. If your mask is clogged or not in good condition, replace it.

For Half-Face

Do a quick visual check of the inside and outside of your mask. Make sure that the valves (the little rubbery seals on the inhalation and exhalation points) are present and in good condition. Make sure there are no cracks or tears in your mask. Ensure that your filters are firmly attached. Correct any of these issues before proceeding with your work.

After you take it off

For disposable

Do another quick visual check of your mask. If everything is still in order, seal your mask inside a baggie and put it somewhere safe.

For Half-Face

Wipe all surfaces of the mask that touch your face with a respirator cleaning wipe. If you don't have any, use the following: For masks made of natural rubber, use a non-alcohol based antimicrobial wipe. For masks made of silicone or plastic, wipe with isopropanol (isopropyl alcohol, or rubbing alcohol). This step is less about the effectiveness of your mask and more about preventing build up of oils from the skin which can degrade the mask over time, necessitating replacement, as well as causing skin breakouts!

Seal your mask inside of a baggie or well-sealed (and clean!) coffee can and put it somewhere safe.

🧼 Once a month you should remove the cartridges and clean your mask with soap and water, and hang it up to dry. This keeps the inside of your mask smelling pleasant. Sweat and condensation from your breathing can build up in there over time and cause the mask to smell unpleasant.

🤔 How often do I need to replace my respirator, or cartridges?

Filters will only last so long! Keep in mind that whether or not you are actively breathing through your respirator (IE: wearing it) it is still filtering the air around you. The average Organic Vapour filter, which is what you should be wearing at the least for spraying, lasts approximately 24–48 hours. That's it! Not very long, right?

The good news is that you can extend the life of your filters dramatically by placing them into a sealed container, like a baggie or coffee can, as discussed in the section above. My staff generally see a lifetime of 1–2 weeks from their filters, and most staff are using their filters at least once a day.

💁 How do I know it's time to replace them?

For Disposable, N95 and above Your respirator is a simple filter made up of layer of material that filter out small particulates from the air. Eventually your respirator will become clogged and need to be replaced. This is not a matter of time, it is a matter of volume of filtering, something not easily tracked.

As a general rule of thumb, when your filter is ready to be replaced, you will know it because it will get harder to suck a good deep breath in. As soon as you start to feel this, replace your respirator. For Half-Face

Organic Vapour Cartridge – Because this is filtering vapours (or aerosols), you will know it is time to replace it the moment you smell or taste anything through the filters; even the tiniest bit. Throw them out and get new ones.

N95 Prefilter

Please see the explaination for disposables above, your prefilter works the same way. If your prefilter is built into your organic vapour cartridge, it is a matter of volume of filtering, something not easily tracked.

I've got this bandana/old respirator of my uncles/some other thing…

❌ Cloth is not an effective filter against either particulate or vapours. ❌

Your respirator needs to be yours. Quite aside from the obvious sanitation issues, if the respirator belongs to someone else, it may not fit correctly and is therefore ineffective.

You're just trying to scare us. No one actually gets sick from this. ☠️ ☠️

There are several people here on the [DenofAngels] forums that have stepped up to talk about the health problems that they have suffered as a result of exposure to chemicals in either this hobby or others.

NON ORIGINAL POST NOTE: Before you dismiss the risks involved please realize that even my friend, a professional artist has experienced the direct effects of long term exposure to harsh chemicals and resins for both film and personal BJD casting even when frequently taking proper protection.

🛍️ 🛒 Where do I get these things?

Disposable respirators are readily available in home improvement stores and pharmacies; just make sure you get one that says N95, or above, as discussed earlier. You can also refer to post #3 below for a Shopping Guide.

Half-face respirators are sometimes available in home improvement stores, but are also readily available from safety suppliers (many of which are open to the general public) and online.

🤢 I worked without my mask and now I'm not feeling well. Am I going to be okay?

This question is best discussed with your Doctor. My speciality is prevention, not treatment. I can tell you what results you may incur, but I cannot and will not attempt to diagnose your health, especially not over the internet.
