Gas masks are also reusable after decontamination. For this reason, the MSA CBRN Ultra Elite Gas. Gas masks can be useful when FFP3 masks are lacking or when operating in restricted military situations. The filter and the powered air-purifying respirator are also positioned at the back of the surgeon, away from the patient’s airways and from virus projection during the trachea incision. SGE 400/3 Tactical 40mm NATO Gas Mask with NBC-CBRN Filter Exp 07/2025 BRAND NEW 3 - SGE 400/3 Tactical 40mm NATO Gas Mask with NBC-CBRN Filter Exp Surf. The filter in the device is comparable with an FFP3 filter and can be fully effective for hours without performance degradation.

2 By contrast, the gas mask, originally designed to protect soldiers against biological and chemical attacks, provides full protection. 1 An additional concern is the potential risk of progressive degradation and increasing porosity, which could explain the lower efficiency of FFP2 or FFP3 masks compared with powered air-purifying respirators. However, their efficacy for SARS-CoV-2 protection has not been explored, and the virus has a smaller calibre (0.1–0.15 µm). FFP2 or FFP3 masks can provide proper protection, as these masks have an efficiency of 95%–99% when tested with 0.30 µm particles.
The French Army Biomedical Research Centre provided our hospital with military masks equipped with P3 filter cartridges and an integrated ventilation unit that would allow safe performance of this procedure when faced with a high risk of virus transmission ( Figure 1). Tracheotomy is frequently indicated for patients with COVID-19 suffering from severe acute respiratory syndrome (SARS).
Awareness of this device and the ability to perform surgery with this procedure could be crucial during pandemics.
