Natural Gas Fires in BSCs - Statement by NSF 49 - 2018 Annex E - Page 13: E.3.3.1 Service valves 
"Service valves allow inert gases, air or vacuum lines to be plumbed into the BSC. Many models allow for the easy installation of these valves in the field, however, it is generally less expensive and easier to have the required number of valves installed when the unit is ordered. Although many users connect natural gas to a service valve in the cabinet, this practice should be avoided if possible, because open flames in a Class II BSC disrupts the airflow, and there is the possibility of a buildup of flammable gas in BSCs that recirculate their air."

40-Year Anniversary of Sverdlovsk Anthrax Accident
Forty years ago, on [2 Apr 1979], there was a major leak of deadly anthrax spores from the Soviet biological warfare facility at Military Compound 19 on the edge of Sverdlovsk. The strain of the pathogen, Anthrax 836, was the deadliest.

Characterization of the total and viable bacterial and fungal communities associated with the International Space Station surfacesChecinska Sielaff et al. Microbiome (2019)
To fully appreciate the true number and diversity of microbes that survive in the ISS, molecular and culture-based methods were used to assess microbial communities on ISS surfaces. Samples were taken at eight pre-defined locations during three flight missions spanning 14 months and analyzed upon return to Earth.

The cultivable bacterial and fungal population ranged from 104 to 109 CFU/m2 depending on location and consisted of various bacterial (Actinobacteria, Firmicutes, and Proteobacteria) and fungal (Ascomycota and Basidiomycota) phyla.
