Ladders must be inspected before each use to verify structural integrity. Damaged ladders must be removed from service immediately and destroyed so they cannot be reused. Side rails must be straight without bends or dents. Rungs must be clean and free of grease or slippery substances. All fasteners must be tight; loose fasteners indicate age or damage. Rope and pulleys on rope ladders must be in good condition. Frayed or damaged rope indicates age and failure risk. Non-slip feet must be present at the base preventing slipping. Lost or damaged feet must be replaced immediately. Metal ladders must be inspected for corrosion. Rust weakens metal and may cause failure. Wooden ladders must be inspected for cracks, splits, or rot. Wood with visible damage should be destroyed. Fiberglass ladders provide non-conductive protection useful near electrical hazards. Fiberglass can become brittle with age; replacement per manufacturer recommendation is appropriate. Storage of ladders should prevent damage and weather exposure. Horizontal storage prevents bending of side rails. Vertical storage takes less space but requires secure fastening. Climate control prevents extreme temperature effects on wooden or fiberglass ladders. Heat can soften adhesives in fiberglass. Cold can make materials brittle. Proper ladder care extends useful life and prevents accidents.
