If the MRT is not present, what else can be used to manually open any oxygen compartment?

• A. Screwdriver
• B. Coin
• C. Toothpick
• D. Stir stick or straw, a pin, paperclip

Answer: (D)

Opening an oxygen compartment without the MRT relies on reaching the release mechanism with a small, rigid object. The door’s latch can be actuated by tools that can be inserted through the access opening. A stir stick or straw provides the right length and stiffness to push or twist the latch and release the door. A pin or paperclip can be straightened and used as a makeshift instrument to depress the release or engage the latch if the mechanism accepts a small rigid probe. These options fit through the opening and can operate the latch without damaging the door. Screwdrivers are typically too large and risk damaging parts or causing injury. A coin may not engage the release reliably or reach the mechanism. A toothpick is usually too fragile for this task. Hence, a stir stick or straw, a pin, or a paperclip are the practical substitutes.
