用法說明
How is "Safety" different from similar structures?What usage mistakes are common with "Safety"?
safety of doing vs. safety to do
- safety of doing 通常用於描述「進行某項活動本身的安全性」，強調活動的性質或狀態。
- safety to do 則較常出現在「it is safe to do」的結構中，用於評估「去做某件事是否安全」，是一個更整體的判斷。
- 在名詞性短語中（如報告標題、規則說明），safety of [名詞/V-ing] 是更標準的搭配。
- 口語中，safe to do 的用法遠比 safety to do 常見；後者有時被視為較不正式的簡化說法。 EN: The report questioned the safety of operating the machinery alone. 翻譯: 這份報告對獨自操作這台機器的安全性提出了質疑。
EN:It is not safe to operate the machinery without training.
翻譯:未經訓練就操作這台機器是不安全的。
總結建議
一般情況下，使用「safety of + 名詞/V-ing」來描述事物內在的安全屬性，而使用「(it is) safe to + 動詞原形」來表達做某事的建議或評估。

常見錯誤
What are common mistakes with "Safety"?Which "Safety" sentences look correct but are wrong?
×We need to ensure the safety of the workers.
✓We need to ensure the safety of the workers.
The original sentence is grammatically correct. This entry highlights that learners sometimes mistakenly think 'safety' is uncountable in all contexts. While 'safety' is primarily uncountable, it can be used countably in specific, formal contexts (e.g., 'road safeties' is wrong, but 'different safety features' uses it as a modifier). The main mistake is over-correcting and never using it in a countable way when appropriate.
×For safety reason, please wear a helmet.
✓For safety reasons, please wear a helmet.
The phrase 'for safety reason' is incorrect. The standard fixed phrase is 'for safety reasons' (always plural), or alternatively 'for reasons of safety'. This is a common collocation error.
×Your safety is the most important.
✓Your safety is most important. / Safety is the most important thing.
Using 'the most important' is incorrect because it implies a comparison within a specific group (e.g., the most important *of these*). When stating a general, absolute priority, 'most important' (without 'the') is used. Alternatively, complete the comparison with a noun like 'thing' or 'factor'.
×I worry about your safeness.
✓I worry about your safety.
'Safeness' is a rarely used word that sounds unnatural in most contexts. The standard and natural noun form is 'safety'. Learners sometimes incorrectly create nouns from adjectives by adding '-ness' where a different noun form exists.
×He is in safety now.
✓He is safe now. / He is in a safe place now.
The phrase 'in safety' is not used to describe a person's state. 'In safety' is an adverbial phrase describing how an action is performed (e.g., 'They arrived in safety'). To describe a person's condition, use the adjective 'safe'.
×This is a good safety.
✓This is a good safety feature. / This provides good safety.
As an uncountable noun, 'safety' typically cannot be used with an indefinite article ('a') or described with 'good' directly before it when standing alone. It needs a following noun (like 'feature', 'measure', 'record') or should be used in a phrase like 'provides safety'.
