The differences between sit harnesses and full-body harnesses, especially in the context of fall arrest systems:
- Sit Harnesses: These are more commonly used in activities like climbing, sailing, and rigging where mobility and comfort are key. They wrap around your waist and thighs, providing good support for sitting positions. However, for fall arrest purposes, they’re not always ideal. Why? Because in the event of a fall, a sit harness can put a lot of pressure on your waist and may not distribute the force evenly across your body.
- Full-Body Harnesses: These are the go-to for most fall arrest systems. They include straps around your legs, waist, chest, and shoulders, offering a more secure fit and better distribution of force in the event of a fall. This means in case you do take a tumble, the impact is spread across a larger area of your body, reducing the risk of injury. Full-body harnesses are particularly crucial in situations where there’s a risk of a free fall or when working at great heights.
Attachment Points: The right attachment point is crucial for safety. For sit harnesses, the attachment is usually at the waist, which is great for activities where you need to stay upright. In full-body harnesses, the attachment is often at the chest or back, which is safer for fall arrest because it helps to keep you upright and distribute the force of the fall.
Remember, always choose the right type of harness based on the activity and risks involved. Safety first! And if you’re working at heights, training and proper use of equipment is key.
