Which two organizations are referenced in relation to drum flange clearance above rope?

• A. ANSI and PCSA
• B. OSHA and ISO
• C. ANSI and OSHA
• D. PCSA and ISO

Answer: (A)

The point here is identifying who provides the specific guidance on drum flange clearance above the rope. The standard references for this exact detail come from ANSI and PCSA. ANSI, the American National Standards Institute, publishes crane and rigging standards that cover how rope should wrap on a drum and how much clearance is needed to keep the rope from rubbing the drum flange. PCSA, a crane-safety association, gives practical safety guidance and recommended practices on drum rope handling and ensuring adequate flange clearance. OSHA and ISO deal with broader regulatory or international standards, but the precise drum-flange–above–rope guidance cited in this context is typically drawn from ANSI and PCSA, making that pair the correct reference.
