Which of the following statements is true concerning the actions of a properly organized rescue party for removing an unconscious victim from a tank containing toxic vapors?
• Enclosed space rescue procedures and dangers of toxic or oxygen-deficient atmospheres • The priority of rescuers’ safety before assisting the victim • Difference between testing for explosive vapors vs. providing breathable air
• Ask yourself: What is the first concern when a rescue party approaches a tank with toxic vapors— the victim’s injuries, the atmosphere, or respiratory equipment? • Which action must be done before any person enters a potentially dangerous tank, even during a rescue? • Which of these options, if done first, could actually put the rescue party at serious risk?
• Verify which step comes before personnel entry in standard enclosed-space/tank entry procedures. • Check which choice focuses on ensuring the atmosphere is safe rather than treating the victim’s injuries right away. • Eliminate any choice that assumes it is already safe to be inside the tank without prior testing or control of the atmosphere.
