Emergency release
Getting a tied person out of rope quickly when something goes wrong; rope teachers advise keeping safety shears within reach so the rope can be cut.
Emergency release means getting someone out of rope fast, for example if they faint or a fire alarm sounds, the cases Anatomie Studio gives for keeping safety shears at hand at all times. The ESINEM Shibari Classes course calls a bladed knife a very bad idea around someone who is panicking or having a fit and favors emergency (EMT) shears, which it describes as having a blunt, flat tip that can slide under rope without injuring the person. It advises keeping the cutting tool in a fixed place that can be found even in the dark, never leaving a tied person alone, and tying hands so they can be freed without undoing everything. Rope 365 also mentions safety hooks, discourages knives and kitchen scissors, and recommends a first-aid course.
