A Suspension Trauma Strap is a safety device designed to be used in situations where a person is suspended in a harness for an extended period, such as in rescue or fall protection scenarios. The strap helps prevent suspension trauma, a condition caused by prolonged hanging in a vertical position, which can lead to serious health issues like blood pooling in the legs, fainting, or even death. Suspension trauma occurs because when a person is suspended upright without movement, blood circulation is impaired, particularly in the legs.
