Rope and restraint: a safety primer

What rope can actually injure

• Nerves — particularly the radial nerve in the upper arm, the median nerve at the wrist, and the peroneal nerve at the knee. Nerve injury can be permanent.
• Circulation — restricted blood flow causes numbness, colour change, and over time, real damage.
• Joints — overextension or pressure on knees, shoulders, and elbows.
• Skin — friction burns, especially if rope is pulled across the body fast.
• Falls — anyone tied up cannot catch themselves. A faint while standing tied can break bones.

Early warning signs to stop immediately

1. Numbness, tingling, or pins-and-needles anywhere.
2. A limb going pale, blue, or cold.
3. Sharp or shooting pain (not the dull "this is intense" sensation).
4. Weakness — can't make a fist, can't lift a thumb.
5. Going light-headed or grey.

Non-negotiable gear and habits

• Safety shears (EMT shears, blunt-tip) within arm's reach of whoever is tied. Always. No exceptions.
• Never tie around the front of the neck. Ever. Breath play around the neck has killed people; rope around the throat compounds the risk.
• Never leave a tied person alone, even for a minute.
• Check in regularly — "squeeze my hand," "wiggle your fingers," "colour?"

Suspension is a different sport

Floor work (tying on the ground, no weight on the rope) and suspension (any of the body's weight supported by rope) are completely different skill levels. Suspension can cause sudden nerve damage, equipment failure, and falls from height. Do not attempt suspension without years of in-person training and proper hard points.

How people actually learn

• In-person classes from named, well-reviewed teachers.
• Local rope communities — many cities have monthly "rope jams."
• Books from credible teachers (e.g. Two Knotty Boys for basics; Midori for nuance).
• Lots of self-tying practice before tying anyone else.

If something goes wrong

1. Cut the rope. Shears, immediately. Don't try to undo knots.
2. Get the person on the ground or supported.
3. Check movement, sensation, colour distally.
4. If numbness persists more than a few minutes after release, get medical care.
5. If you suspect a nerve injury, see a doctor. Catching it early matters.
