LCt50 Calculator

Utility for determining three different lethal concentration and time (LCt50) calculations when using chlorobenzalmalononitrile (CS) non-lethal chemical agent inside a structure. The formulas are based on a government study using animals and soldiers to determine the amount of agent that will likely kill 50% of the people in a closed sealed space using the amount of agent and time as a factor.

The app's easy-to-use forms require the user to enter the length, height and width of a structure, along with how much agent was used. If you want to determine the amount of the agent you can safely use in a building, the app will tell you the LCt50 after one simple numeric entry by the user. You can also determine how much agent to use for any LCt50 you want to establish.

Every team leader responsible for the delivery of chemical agents can make use of this app.
