A SAR helicopter has landed a litter on deck to medevac a patient from your vessel. After ensuring that it has been grounded, what precautionary action should you take prior to loading the patient into the litter?

Correct Answer: Option B — unhook the litter from the winch cable while the patient is being loaded

During helicopter medevac operations, the rescue litter must be grounded to discharge static electricity before personnel touch it, and the rescue hoist cable must remain unhooked while loading the patient to prevent sudden snatch loads or winch activation injuries.
