====Damage control====
The tank has a [[gaseous fire suppression|halon firefighting]] system to automatically extinguish fires in the crew compartment. The engine compartment has a firefighting system that is engaged by pulling a T-handle located on the left side of the hull. The Halon gas can be dangerous to the crew.<ref>{{cite web |url=https://www.cdc.gov/niosh/npg/npgd0634.html |title=NIOSH Pocket Guide to Chemical Hazards |publisher=CDC |url-status=live |archive-url=https://web.archive.org/web/20170818091459/https://www.cdc.gov/niosh/npg/npgd0634.html |archive-date=18 August 2017}}</ref> However, the toxicity of [[Halon 1301]] gas at 7% concentration is much lower than the combustion products produced by fire in the crew compartment, and CO<sub>2</sub> dump would be lethal to the crew.<ref name="The_Chieftain">{{Citation|last=The_Chieftain|title=Chieftain Chats Abrams|date=14 October 2018 |url=https://www.youtube.com/watch?v=aladW_D4nKU|access-date=21 February 2019|archive-date=14 October 2018|archive-url=https://web.archive.org/web/20181014180752/https://www.youtube.com/watch?v=aladW_D4nKU&gl=US&hl=en |url-status=live}}</ref>

The crew compartment also contains small hand-held [[fire extinguisher]]s. Fuel and ammunition are stored in armored compartments with [[blowout panel]]s intended to protect the crew from the risk of the tank's own ammunition [[cooking off]] (exploding) if the tank is damaged. The main gun's ammunition is stored in the rear section of the turret, with blast doors that open under power by sliding sideways only to remove a round for firing, then automatically close. Doctrine mandates that the ammunition door must be closed before arming the main gun.<ref name="The_Chieftain"/>
