OPERATION AND SAFETY

• Do not use this equipment if you are in poor health, taking medications, drugs, or have been consuming alcohol, all of which may impair your ability to work safely on this product.
• All equipment must be inspected before use to ensure its integrity, good repair, and suitability for intended use.
• Inspect before use. Do not use this scaffolding if damaged or parts are missing.
• Always use this scaffolding in conformity with local or national legislation which applies.
• Scaffolding must be erected, altered, and dismantled by qualified workers or under the direct supervision of a qualified person.
• The base must be firm and level enough to support the load of scaffolding, workers, and materials. Sills and base plates are required on soil and unstable ground, or where any leveling adjustment is needed. The sill must be sound, rigid, and capable of supporting the maximum loads without settlements or deformation.
• Leveling jacks must be adjusted within the limits specified by local regulations.
• Frames must be plumb, level and spaced to adequately support loads.
• Always install inner and outer handrails to the stair before using the stairway.
• The upper adaptable handrail post MUST be secured at the correct compatibility position to the handrail with bolts.
• All handrails MUST be secured to the stair with bolts or locking pins before using the stairway. ALWAYS secure both ends of the stair to the scaffolding structure with bolts (TOP and BASE) to prevent lifting of the stairway.
• To prevent the scaffolding from overturning, scaffolding MUST be tied to a building or structure using wall attachments or guyed when built above the 3:1 ratio. Guying or tying a scaffolding may require the direction of a professional engineer. Wall attachments MUST be used to ensure stability for heights exceeding the 3:1 ratio. Wall attachment must be installed at every 15 ft in height and every 21 ft in length of the scaffolding structure.
• All workers MUST be protected from falls by guardrails or a personal fall arrest system when working at 10 ft from ground or more.
• Guardrails must be installed on all open sides of the platform where a person could fall a distance of 10 ft. or more. The top rail must be placed 40-44 in. above the work surface. An intermediate rail must be placed halfway between the top rail and the work surface. DO NOT STAND ON OR PLACE LOADS ON GUARDRAILS.
