She went over the information Dubois-Volkov had given them on what to expect at the facility, and how to identify the different agents correctly in case they couldn't make sense of the Russian labelling, or it was labelled in code. The Kolokol-1 that they wanted would be stored in aerosol form, suspended in small glass-lined metal cylinders and must not be confused with sarin gas, which was a fatal nerve agent also stored in aerosol form, and which the facility had in short-term storage at the moment in the same room, according to Yuri. There were also going to be stores of mustard gas, chlorine gas, cyanogen chloride, or CK, hydrogen cyanide, and phosgene. All of them could be fatal, but the likelihood of anything actually happening was very low – everything was very carefully stored; safety being of paramount importance to the people working in the facility.
