Fall Safety Harnesses: A Hidden Danger
Summary
While safety harnesses are meant to protect, they can also pose a deadly risk. Just five minutes suspended in a harness can lead to unconsciousness, and after fifteen minutes, death can occur.Keywords

Safety harnesses are crucial in many work and recreational settings. However, it's not widely known that they can also be deadly.Harnesses become dangerous when a person is suspended for more than five minutes in an upright position, leading to suspension trauma. For instance, if a carpenter falls and is caught by his harness, he might die within 15 minutes due to this condition. Workers lowered into shafts face similar risks if left suspended too long. Although fall protection researchers have been aware of suspension trauma for years, many users and safety professionals remain unaware.
Suspension trauma results from orthostatic incompetence. This condition occurs when someone remains still and upright for extended periods, which can be worsened by heat and dehydration. It's often seen in military parades when soldiers stand at attention for long durations. Supervisors can mitigate this by training personnel to keep their knees slightly bent.
In suspension trauma, immobile legs allow gravity to pull blood downward, pooling in the lower legs and reducing blood flow back to the heart. The heart's output decreases, and it speeds up to maintain brain blood flow. If restricted too much, the heart slows abruptly, causing fainting. When fainting occurs, falling to a horizontal position helps restore blood flow. However, a harness prevents this, and the resulting low heart rate can lead to brain blood loss below critical levels.
Orthostatic incompetence doesn’t occur often because leg movement usually aids blood flow. In suspension, though, the worker's legs dangle, support is limited, and harness straps can compress veins, further restricting blood flow. These factors combined keep the worker upright, even if unconscious, which can be fatal.
To prevent these dangers, a well-planned rescue policy is essential for those using fall arrest harnesses. The very equipment designed to save a life in a fall can also be its biggest threat.
