For how long should vinegar be applied liberally over the affected area to prevent further venom release from remaining nematocysts?
Answer
At least 30 seconds.
The application time for vinegar during the deactivation phase is a specific protocol designed to ensure comprehensive chemical neutralization of the stinging cells. Medical guidance advises that vinegar must be applied liberally to cover the entire affected zone and left in place for a minimum duration of 30 seconds. This contact time allows the acetic acid to fully penetrate and deactivate the venom-injecting mechanisms housed within the nematocysts, thereby halting any further injection of venom before the physical removal process begins. Insufficient contact time risks incomplete deactivation.
