![]() ![]() Six soldiers demonstrating the use of a gas mask during the First World War. The HSE decided that old untested gas masks should not be handled or worn as teaching aids in schools because visually distinguishing between hazardous and safe filters is difficult or impossible. The results showed that the filters of 29 gas masks contained asbestos, and six filters included blue asbestos, considered the most hazardous for health. In 2014 the UK Health and Safety Executive (HSE) investigated 34 old British and German gas masks. Possible risks were not properly addressed until the 2000s. No research-based information is evidently available on the asbestos exposure of contemporary gas mask wearers or current gas mask owners and wearers.

Those exposed to asbestos at work have suffered from, for example, lung cancer, to a far greater degree than other members of the population. However, the focus has been on the workers of factories producing gas masks during the Second World War whose health and causes of death were analysed in the 1970s and 1980s in Britain and Canada, for instance. The connection between the filter cartridges of old gas masks and asbestos has long been known around the world. In this blog post, we explain how we investigated the matter and what we eventually found out. In spring 2020 we decided to find out whether these suspicions were true. However, we had to scrap these plans at the last minute when we discovered that the filters of old gas masks may contain asbestos. In 2015 we made plans to place one of the civilian gas masks on display in the University Museum’s new main exhibition, The Power of Thought. The collections also include an equine gas mask dating back to the 1930s or 1940s which is of an unknown origin. The University Museum has received the masks from hospitals and University of Helsinki departments. ![]() The collections of the Helsinki University Museum include eight gas masks, of which seven are from the 1930s and intended for the civilian population. The gas mask originally belonged to the University of Helsinki Department of Pharmacology. The two cheeks are not filled completely.A civil defence gas mask from the late 1930s included in the collections of the Helsinki University Museum. The form is just remembering the original filters but is much more basic Of course the new fake filters dont offer any protection, they are just for decorative purpose.Ī very big thanks to selectnone for the original design of the filter and to have attached the Fusion 360 files to make all modifications easier.Īdvantages of this remix (new 10 mm high version vs original version):ġh 23m instead of 4h 14m printing time for each filterĢ6g instead of 76g filament for each filterįilter easier to insert in the cheek pocket The filters are necessary for two reasons: to fill the space inside the cheeks and to install the filter covers over the holes without using the original filters (safety of the original filters is also not 100% demonstrated and they can release powder or substances when breathing). Fake filters that dont need support and have a really short printing time for the famous "monkey" gas mask PBF. ![]()
