Which of the following states that a lithium-ion battery involved in a fire shall not be moved in an elevator or interior stairs?

The statement is true. When a lithium-ion battery is involved in a fire, it poses significant hazards, including the risk of explosion, release of toxic gases, and further fire propagation. Moving such a battery through an elevator or along interior stairs can escalate dangers both to the individuals involved and to others in the vicinity.

Specifically, using an elevator to transport a battery in a fire scenario could trap people in a confined space if the battery were to ignite or explode, making evacuation more challenging. Similarly, using interior stairs could expose first responders and civilians to the smoke and toxic fumes emitted from a burning battery.

Due to these safety concerns, protocols often dictate that lithium-ion batteries—especially those suspected to be hazardous—remain in place and are handled with care by trained professionals in a controlled manner. Therefore, the regulation not to move a lithium-ion battery involved in a fire aligns with best practices for ensuring safety during emergency situations.
