What is the correct action after Halotron used to extinguish a lithium ion battery fire must be cooled with?

• A. Water
• B. Air
• C. Foam
• D. Dry ice

Answer: (A)

Cooling with water is necessary after using Halotron because Halotron stops the flame and interrupts the chemical reactions, but it doesn’t remove the significant residual heat from hot lithium-ion cells. These batteries can continue to undergo thermal runaway internally, so applying water provides the needed cooling to absorb heat, bring the temperature down, and reduce the risk of reignition. Water’s high heat capacity makes it effective for this purpose, plus a fine spray helps reach exposed cells and surfaces. Air won’t remove heat, foam isn’t a reliable cooling method for this scenario, and dry ice could complicate heat transfer and safety. So cooling with water is the correct action.
