Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'люк' (hatch) generically; 'manway' is specifically for human entry in technical contexts. Not equivalent to 'проход' (passage/corridor).

Common Mistakes

  • Using it as a general synonym for 'door' or 'hallway'. Confusing it with 'walkway'. Assuming it is a common word.
