Identifying numbers are embossed on chain links at intervals no greater than how many feet apart?

• A. 3'
• B. 5'
• C. 7'
• D. 10'

Answer: (A)

Readability and accountability of the chain’s capacity are what this is about. Marking identifying numbers on each link so you can tell the chain’s grade, load rating, or other specs at a glance is essential for safe use. Placing those embossed markings no more than three feet apart ensures that, along any portion of the chain, a reader will encounter a mark within easy reach and sight. This makes it practical to verify the correct chain is being used before lifting and to trace the chain’s specifications if a component is inspected or damaged. If marks were spaced farther apart, you could lose track of the chain’s identity over a longer length, increasing the risk of using a chain with an incorrect rating.

So, the identified practice is three feet between markings.
