OECP Exam Reviewer — Crane Operations, Rigging, Safety & OSHA Compliance (100% Correct Answers)

OECP Exam Reviewer — Crane Operations, Rigging, Safety & OSHA Compliance (100% Correct Answers)A complete OECP (Operator & Equipment Certification Program) exam reviewer featuring verified questions and answers across crane operations, rigging, lifting safety, and OSHA requirements. This resource is designed to help construction professionals, crane operators, and riggers prepare for certification exams with confidence. Key topics covered include: - Crane Signals & Communication - Four types of signals: hand, voice, audible, new - Signal training requirements (mandatory in construction industry) - Only one signal person on a two‑crane pick - New signals must be equally effective - Load Charts & Lifting Safety - Shaded area = structural chart - Load radius = horizontal distance from rotation center to suspended load - Critical lifts = >75% of rated capacity - All lifting devices load tested to 125% - Multi‑crane picks limited to 75% capacity per crane - Electrical Safety & OSHA Standards - Minimum distance to unknown voltage lines = 50 ft - Known voltage lines: never closer than 20 ft (Table A) - Passing below power lines in transport = 4 ft clearance - Highest cause of crane fatalities = electrocution - OSHA tie‑off height during assembly/disassembly = 15 ft - Rigging & Sling Inspection - Qualified rigger required for A/D - Synthetic sling inspection: missing tags, burns, broken stitches, snags, tears, discoloration - Wire rope inspection: corrosion, crushed strands, bird caging, core protrusion, heat damage - Never open wire rope to expose the core - Horizontal sling angle decreases → rated capacity decreases - Personnel Lifting & Man Basket Safety - Man basket doors must swing inward - Smooth edges to prevent injury - Personnel basket proof load tested to 125% - Rated capacity de‑rated 50% when handling personnel - Pre‑lift meeting required before lifting personnel - General Engineering & Operations - Concrete weight = 150 lbs/ft³ - Principle of leverage: weight × distance = distance × weight - Estimated weight formula: length × width × height × unit weight - Boom assembly requires boom composition chart - Pre‑lift planning documented in checklists - Recommended fleet angle for smooth drum = 0.5–1.5° - Maximum shackle/collector ring angle = 120° This reviewer provides exam‑style Q&A with concise rationales, making it ideal for OECP candidates, crane operators, riggers, and safety professionals preparing for certification or compliance assessments
