When arriving at a tower site where a worker has been found unresponsive, the very first action must be to:
Answer: Ensure the scene is safe before approaching the victim
Scene safety must be confirmed before any rescuer approaches an unresponsive victim to avoid creating additional casualties from the same hazard.
Current American Heart Association (AHA) guidelines recommend a CPR chest compression rate of:
Answer: 100–120 compressions per minute
The AHA recommends a compression rate of 100–120 per minute to generate adequate blood flow during cardiac arrest.
The correct compression-to-ventilation ratio for single-rescuer adult CPR is:
Answer: 30:2
For adult CPR with one rescuer, the AHA standard is 30 chest compressions followed by 2 rescue breaths, repeated continuously.
An AED (Automated External Defibrillator) is specifically designed to treat:
Answer: Ventricular fibrillation and pulseless ventricular tachycardia
AEDs deliver a controlled electrical shock to reset shockable cardiac rhythms — specifically ventricular fibrillation and pulseless ventricular tachycardia.
OSHA requires that first aid kits on construction job sites be:
Answer: Readily accessible to all workers at all times
OSHA mandates that first aid supplies be immediately accessible to every worker so care can be administered without delay after an injury.
A worker who has been suspended in a fall arrest harness and rescued must:
Answer: Be evaluated by medical personnel before returning to work
