 For the soft mud, the arrest distance is longer and so arrest forces are lower but the egg is still stopped and is hopefully undamaged.Because fall arrest designs require high-rate-energy capacity design methods, fundamental fall arrest design is tedious and esoteric.Thus, most fall arrest parts and systems are designed to the force standards contained in Federal OSHA 29CFR1910.66 appendix c, a force-type design standard which accounts for required energy considerations.
