Certain types of scaffolding require the use of a personal fall-arrest system to safeguard workers against the dangers of falling from high elevations. A few examples include Aerial lifts, Float scaffolds, Ladder jack scaffolds, and Needle-beam scaffolds. Others require a combination of a personal fall-arrest system and guardrails to ensure worker safety and meet OSHA requirements. Among others, these include Supported scaffolds, Single-point and two-point suspension scaffolds, and Self-contained scaffolds. Whenever you use a personal fall-arrest system, it must include a scaffolding harness to secure workers and prevent dangerous falls. A scaffolding harness is also essential to maintain OSHA compliance.
