If you use solvent in a closed space, make sure that there is good airflow in the work area.
答案解析
解析:
### 题目解析
题目是:“If you use solvent in a closed space, make sure that there is good airflow in the work area.” 这句话的意思是:如果你在封闭的空间中使用溶剂,请确保工作区域有良好的空气流通。
- **A:** “If you use cleaner in a closed space, make sure that there is ventilation in the work area.”
- **解析:** 这个选项的意思是“如果你在封闭的空间中使用清洁剂,请确保工作区域有通风。”这个选项与题目中的“solvent”(溶剂)不同,题目中提到的是“solvent”,而这里用的是“cleaner”,这可能不是一个完全匹配的答案。
- **B:** “Ensure that there is adequate airflow in the work area when using solvent in an enclosed space.”
- **解析:** 这个选项的意思是“在封闭空间中使用溶剂时,确保工作区域有足够的空气流通。”这个选项完全符合题目中的要求,强调了在使用溶剂时需要良好的空气流通来保持安全和健康。
- **C:** “If you use solvent in a confined space, make sure that there is restricted airflow in the work area.”
- **解析:** 这个选项的意思是“如果你在受限空间中使用溶剂,请确保工作区域的空气流通受限。”这个选项实际上是错误的,因为在使用溶剂时,空气流通受限会增加有害气体的浓度,对健康造成危险。
### 为什么选B是正确的
溶剂通常会释放有害气体或蒸汽,如果在封闭的空间中使用它们,空气中的这些物质浓度会增加,可能对健康造成威胁。因此,保持良好的空气流通非常重要。这可以通过增加通风、使用排风扇或确保工作区域有足够的自然通风来实现。
### 联想和生动例子
想象一下你在一个小房间里使用了一种气味很重的清洁剂。如果房间里没有足够的空气流通,气味会越来越浓,可能会让你感到不适,甚至可能引起头痛或呼吸困难。而如果房间有良好的通风,比如开窗或使用排风扇,这些气味和有害气体会被迅速排出,空气变得新鲜,你的工作环境也会更安全、更舒适。
同样的道理也适用于题目中的溶剂。保持良好的空气流通不仅可以帮助排除有害气体,还可以提高你的工作效率和舒适度。
