Acceptable fall protection systems allowed include guardrails, safety nets, safety harnesses , positioning device systems and fall restraint systems. One exception is when the scaffold platform is within 14 inches of the face of the work. Tip: A scaffold can be overloaded by removing the braces, which causes the weight on the scaffold to be distributed to fewer structural members.
