Difficulty: EasyDirect Fact Retrieval

When operating heavy cargo winches in muddy terrain, operators must inspect the synthetic line before each recovery cycle. Unlike steel wire rope, ultra-high-molecular-weight polyethylene winch lines must be rinsed thoroughly with clean, lukewarm water to remove abrasive grit from between the braided strands. Using chemical detergents or high-pressure washers is prohibited because pressurized water forces fine silt deeper into the core fibers. After rinsing, the line should be unspooled completely and air-dried in the shade prior to tension spooling on the winch drum.

According to the passage, what should operators use to remove abrasive grit from synthetic winch lines?

  1. A
    Chemical detergents
  2. Clean, lukewarm waterAnswer
  3. C
    High-pressure washers
  4. D
    Wire rope lubricant

Clean, lukewarm water
The author explicitly states in the second sentence that synthetic winch lines must be rinsed with clean, lukewarm water to remove abrasive grit from between the braided strands.

Step-by-Step Solution
