Halon gas

"I have found an interesting way of rerouting your new halon fire suppression system all the way from Hazmat storage to personnel quarters."

- Dr. Elizabeth Weir

Halon gas is a material used in many fire suppression mechanisms. It is quick acting, non-conductive, non-volatile and leaves no residue behind, which makes it a perfect choice for areas such as a computer labs, libraries and museums. However the gas can be deadly to humans when they react with fire.
