As a Noun: 1. A SAFETY HARNESS is a device of belts or restraints that stops a person from falling or hurting themselves if they do fall. People working on the outside of a building usually wear something like this. Note: 1. The signer in the video is giving an Auslan explanation of the English term SAFETY HARNESS. There appears to be no commonly used Auslan sign for SAFETY HARNESS (but some signers represent this visually using depicting signs, once they have established the topic). If you know a sign for SAFETY HARNESS used by you or other Auslan users (deaf people or interpreters) please go to "Report missing sign" and supply details. Thank you.
