Which is most important when rescuing someone from a permit-required confined space?

• A. having a lifeline attached to the rescuer
• B. providing artificial ventilation
• C. having someone outside to assist
• D. supplementary oxygen

Answer: (D)

The most important factor in rescuing someone from a permit-required confined space is having a trained person stationed outside the space to assist. This standby attendant coordinates the rescue, monitors the atmosphere with appropriate equipment, communicates with the person inside, and can summon emergency responders if conditions deteriorate. Their role is to keep the entry controlled, ensure that only trained rescuers enter, and provide immediate support or abort entry if danger rises. Without this outside support, the rescue becomes chaotic and dangerous, increasing the risk to both the victim and the rescuer. Ventilation can help reduce hazards inside the space and a lifeline or retrieval system aids the rescuer, but these measures depend on good outside oversight and training. Supplementary oxygen, on the other hand, is not a general rescue remedy; introducing oxygen can worsen hazards, ignite flammable atmospheres, and give false readings of safety.
