Toxic gas

{{I=gas grenade.jpg=200=right=The gas grenade Ben used in {{crossref}}}}
In the Purge, the Hostiles used a '''toxic gas''' to kill the DHARMA staff on the Island. Ben used a gas grenade to kill Roger Linus in the DHARMA van. The delivery method at the Barracks is not known. The gas causes severe coughing and bleeding from the nose, leading to death shortly thereafter. The grenades are labeled "...431CTP; ...ARGE GAS". The Hostiles protected themselves from the gas by using gas masks. 

A poison warning label can be seen running up the side of the can with a skull and crossbones at the bottom. The poison label consists of a message in large letters over a message in small latters. The visible characters in the large message are "D-------SON". The visible portions of the small message are "CONTE----OSED." {{crossref}}

Some time later, after Juliet came to the island, Goodwin told her that Ben had him working with chemicals that could kill everyone on the island.

In December 2004, Charlotte and Daniel sneaked away from Jack's group on the beach, making their way to the Tempest, where they ostensibly prevented a toxic gas from being released on the island.  Harper had appeared to Juliet, claiming that Ben wanted the latter to stop them from ''releasing'' the gas, but she was unsuccessful in doing so, and the fact that everyone survived afterwards indicates that it was more likely Ben who wanted to release the gas, as Charlotte suggested. {{crossref}}

* CTP is an abbreviation for the http// MIT Center for Theoretical Physics.
* CTP is also an abbreviation for Critical Temperature and Pressure.
* On the computer screen in the Tempest station is a list of chemicals, O-Ethyl O-(2-diisopropylaminoethyl) methylphosphonite and N,N-diisopropyl-2-aminoethane thiol, which are the immediate precursors for WikipediaVX_(nerve_agent) (http// screencap). WikipediaThionyl_chloride is also shown, and is used to make G series nerve gas. Arsenic trichloride is also shown, as well as benzilic acid.
