Hot work vest-style safety harnesses for general fall arrest have two vertical shoulder straps that have webbing and a buckle to connect across the chest for a secure fit. Vest-style harnesses are easier to put on and take off than crossover harnesses. Hot work harnesses are made from materials that resist damage from flames and sparks that would fray, melt, or burn standard safety harnesses. They are typically worn by workers who are welding and grinding at height.
