What did Edgar Stiles die from on 24?

Answer 1

Poison Gas At 6:59 p.m. in Day 5, during a Sentox nerve gas attack on CTU, Stiles was returning to the main room after trying to check on a colleague, Carrie Bendis, who had gone to check a ventilator system that set off a "trouble flag." Edgar did not make it back in time, and failed to enter the situation room before it was locked down. He died quickly thereafter from inhaling the nerve gas. He receives the silent clock in tribute, at 6:59:56. His last word was "Chloe".[9]
