作業帽

1. Origins, structure, and basic meaning

• Structure: 作業帽(さぎょうぼう) refers to a cap worn for work.
• Basic usage: It appears as something put on before entering a factory or washed after use.

2. Common pitfalls and similar expressions

• Reading the compound ending
  • Unlike 帽子(ぼうし), this word ends in 帽(ぼう), giving the full reading さぎょうぼう.
• Wearing it and protective function
  • 作業帽をかぶる describes putting on a work cap.
  • ヘルメット refers to impact-protection equipment; being worn at a workplace does not make the two items equivalent in protective function.
