IMPROVISED PROTECTION BY CONCEALMENT. IV. SUMMARY OF RESULTS. CONCLUSIONS.

Abstract

The last article discussed in details effects of various ways of sealing window frames
with adhesive tapes, and summarized resulting conclusions.
 For the seven selected toxic warfare agents (phosgene, chloroacetophenone,
chloropicrin, lewisite, sarin, mustard and VX) based on the penetration of sulphur hexafluoride,
SF6 and medium incapacitating concentration LCt50 of the given substance at pressures of 5,
30 and 50 Pa were calculated time when were this concentration reached.
 Various factors such as types of windows, sealing method, wind velocity, type of toxic
substance and its concentration were also discussed in details.
 Performed experiments indicated significance of sealing the openings of improvised
shelters, for example windows, and pointed at suitable possibility to protect thus constructed
shelters.
