Scaffolding safety training is needed by every employee who works on a scaffold, plus anyone who erects, moves, dismantles or inspects one. OSHA requires workers on scaffolds to be trained by a qualified person, and crews that assemble or take down scaffolds need additional training from a competent person.

OSHA's construction standard 29 CFR 1926 Subpart L covers scaffolding, with training requirements in 1926.454. In general industry, 29 CFR 1910.27 states that scaffolds must meet the Subpart L requirements. State-plan states may add their own scaffold rules, so check local regulations as well.

The main scaffold hazards are falls from height, collapse when planks or supports give way, being struck by falling tools or materials, and electrocution from nearby power lines. Missing guardrails, overloading and poor footing make each of these more likely, which is why daily inspection and correct setup matter.

Under OSHA rules, a competent person must inspect scaffolds for visible defects before each work shift. Another inspection is required after any event that could affect the scaffold's structural integrity, such as high winds or an impact. Damaged components must be repaired, replaced or removed from service right away.

OSHA requires fall protection for workers on a scaffold more than 10 feet above a lower level. Depending on the scaffold type, that means guardrails, a personal fall arrest system, or both. Workers below also need protection from falling objects, such as toeboards, screens, debris nets or barricades.
